LPC (Low Pin Count) is a family of 32-bit microcontroller integrated circuits by NXP Semiconductors (formerly Philips Semiconductors).[1] The LPC chips are grouped into related series that are based around the same 32-bit ARM processor core, such as the Cortex-M4F, Cortex-M3, Cortex-M0+, or Cortex-M0. Internally, each microcontroller consists of the processor core, static RAM memory, flash memory, debugging interface, and various peripherals. The earliest LPC series were based on the Intel 8-bit 80C51 core.[2] As of February 2011, NXP had shipped over one billion ARM processor-based chips.[3]

[edit]
Flash programming via UART

All LPC microcontrollers have a ROM'ed bootloader that supports loading a binary image into its flash memory using one or more peripherals (varies by family). Since all LPC bootloaders support loading from the UART peripheral and most boards connect a UART to RS-232 or a USB-to-UART adapter IC, thus it's a universal method to program the LPC microcontrollers. Some microcontrollers requires the target board to have a way to enable/disable booting from the ROM'ed bootloader (i.e. jumper / switch / button).

  • lpc21isp A multi-platform open-source tool to flash LPC microcontrollers over the UART.
  • Flash Magic, a commercial program for Windows and macOS to perform in-system programming of the LPC flash via its UART.
  • nxp_isp_loader, an open-source tool to flash LPC microcontrollers over the UART.
Debugging tools (JTAG / SWD)
  • OpenOCD, an open source software package for JTAG access using a wide variety of hardware adapters.
  • LPC-Link 2, by NXP, a JTAG / SWD debug adapter that has multiple firmware releases available to emulate popular debug adapter protocols, such as: J-Link by Segger, CMSIS-DAP by ARM, Redlink by Code Red Technologies. All connectors are 1.27 mm (0.05-inch) pitch.[36][37]

Documentation

[edit]

The amount of documentation for all ARM chips is daunting, especially for newcomers. The documentation for microcontrollers from past decades would easily be inclusive in a single document, but as chips have evolved so has the documentation grown. The total documentation is especially hard to grasp for all ARM chips since it consists of documents from the IC manufacturer (NXP Semiconductors) and documents from CPU core vendor (ARM Holdings).

A typical top-down documentation tree is: manufacturer website, manufacturer marketing slides, manufacturer datasheet for the exact physical chip, manufacturer detailed reference manual that describes common peripherals and aspects of a physical chip family, ARM core generic user guide, ARM core technical reference manual, ARM architecture reference manual that describes the instruction set(s).

NXP LPC

View on Grokipedia
from Grokipedia
The LPC (Low Pin Count) is a family of 32-bit integrated circuits developed by , featuring processor cores and targeted at embedded applications from low-power sensors to high-performance industrial systems. Originally introduced by Semiconductors in the early as one of the first integrated flash-based microcontrollers, the LPC line transitioned to NXP following the spin-off of Philips Semiconductors into an independent company. By 2018, the portfolio had grown to over 400 devices, building on more than 11 years of innovation to support diverse markets including IoT, automotive, and . Key defining characteristics include scalable performance with clock speeds up to 204 MHz, memory options reaching 1 MB of flash and 282 KB of SRAM, and integrated peripherals such as USB, CAN, Ethernet, and LCD controllers for enhanced connectivity and efficiency. The LPC family encompasses multiple series tailored to specific needs, including the entry-level LPC800 with Cortex-M0+ cores for cost-sensitive designs, the LPC1100 for ultra-low power applications, the performance-oriented LPC4000 and LPC4300 series with Cortex-M4 and dual-core options, and advanced lines like LPC54000 and LPC5500 for IoT and secure processing using Cortex-M33 cores. Supported by NXP's MCUXpresso software ecosystem and a 10-year product longevity program, the LPC microcontrollers emphasize ease of development, reliability, and long-term availability for engineers.

Overview

Introduced in 2014 as part of NXP's push toward accessible Cortex-M0+ solutions, the LPC81x series saw updates like the LPC82x by around 2014-2020 for greater peripheral density and memory, targeting applications in simple control systems, LED lighting, energy metering, and sensor interfaces. Memory configurations in the LPC81x family vary by variant, with the base LPC81x models offering up to 16 KB of on-chip and 4 KB of SRAM, while the higher-integration LPC82x extension doubles these to 32 KB flash and 8 KB SRAM, enabling more complex without external components. A key feature is the support for flash read-while-write operations through In-Application Programming (IAP) and (ISP), allowing code updates without halting execution. The family emphasizes versatile integration, including an analog comparator for , multiple s such as the multi-rate timer (MRT), state-configurable /PWM (SCTimer), windowed (WWDT), and self-wake-up (WKT), as well as flexible GPIO with up to 29 pins supporting configurable pull-up/pull-down resistors, open-drain modes, interrupts, and high-current drive (up to 20 mA on certain pins). Packages range from compact TSSOP20 and HVQFN33 options, ensuring pin compatibility across variants for scalable designs.

Legacy Series

LPC900 Series

The LPC900 series comprises a family of low-cost, 8-bit microcontrollers from (formerly Semiconductors), built around an accelerated two-clock 80C51-compatible core that executes instructions in reduced clock cycles for improved performance over traditional 80C51 devices. The core operates at up to 18 MHz using an external , enabling efficient handling of basic embedded tasks while maintaining compatibility with legacy 80C51 software and tools. Some variants support an internal RC oscillator for simpler designs, though external clocks provide the highest speeds. Memory configurations in the LPC900 series emphasize flexibility for small-scale applications, with on-chip ranging from 1 kB to 16 kB that is byte-erasable and supports (ISP) and in-application programming (IAP) for field updates without specialized hardware. Data RAM is typically 128 to 256 bytes, sufficient for stack and variable storage, while higher-end models like the P89LPC935 and P89LPC936 include an additional 512 bytes of auxiliary RAM. options up to 512 bytes are available in select devices for non-volatile data storage, such as serialization codes, with endurance ratings of 100,000 erase/write cycles. In-circuit programming is facilitated through a serial interface, allowing reprogramming via standard connectors without removing the device from the board. Key integrated peripherals simplify system design by reducing external components, including an enhanced UART with fractional baud rate generation and break detection for , a 400 kHz interface for peripheral connectivity, and two 16-bit timers/counters that support PWM, functions, and capture/compare modes. Brown-out detection circuitry monitors supply voltage (2.4 V to 3.6 V range) and can trigger a reset or to protect against power glitches, enhancing reliability in unstable environments. Additional features like and a with oscillator fail detection further support robust operation. The series is housed in compact, cost-effective packages such as 8-pin to 44-pin DIP, PLCC, TSSOP, and LQFP, with pin counts scaling from basic 20-pin DIP/PLCC for minimal I/O to 44-pin options for more GPIO and peripherals, making it suitable for legacy upgrades in space-constrained designs. Introduced in the early , the LPC900 series found use in simple appliances like vacuum cleaners and handheld devices, as well as early PC interfaces requiring low-power, high-integration control.

LPC700 Series

The LPC700 series represents Philips Semiconductors' (now NXP) early entry into 8-bit microcontrollers, based on an accelerated version of the 80C51 core. These devices were designed for cost-sensitive, high-volume applications requiring minimal external components, with the core executing instructions at twice the speed of a standard 80C51, achieving cycle times of 300–600 ns. Introduced in the late , the series emphasized one-time programmable (OTP) variants alongside mask-programmed options to enable flexible production without the need for full mask ROM customization. Memory configurations in the LPC700 series typically include 1–4 KB of mask ROM or OTP for program storage, paired with 128–256 bytes of on-chip RAM for data and stack operations. For example, the P87LPC762 model provides 2 KB OTP and 128 bytes RAM, while higher-end variants like the P87LPC764 offer 4 KB OTP with the same RAM size, sufficient for simple control tasks without external . The OTP mechanism allows end-users to program the device once during , bridging the gap between fixed mask ROM and more advanced reprogrammable technologies. Peripherals are kept minimal to maintain low cost and pin efficiency, featuring a full-duplex UART for , basic quasi-bidirectional I/O ports, two 16-bit timers/counters, and an interface for peripheral connectivity. Additional elements include two analog comparators for simple , a for reliability, and up to eight keypad interrupt inputs, tailored for direct interfacing with low-pin-count systems like PC add-ons. The core supports operation at 12 MHz in standard configurations, scalable to 20 MHz at higher voltages (4.5–6.0 V), with low-power modes (idle and power-down) to extend battery life in portable devices. Packaging options focus on compact, cost-effective formats such as 14-pin and 20-pin PDIP and SOIC, to suit low I/O needs while targeting a bill-of-materials cost under $1 in volume. This design philosophy prioritized integration for peripherals and embedded controls, making the LPC700 series a foundational legacy line before the shift to flash-based and architectures in later families.
