NXP Semiconductors LPC1810FET100,551

Overview

LPC1810FET100 from NXP Semiconductors is a 32-bit ARM Cortex-M3 flashless microcontroller operating at up to 180 MHz, featuring 136 kB on-chip SRAM, no Ethernet or LCD controller, and zero USB interfaces. It targets cost-optimized industrial control and metering applications requiring deterministic real-time response without high-bandwidth peripherals.

For engineers reviewing the LPC1810FET100 datasheet, LPC1810FET100 pinout, LPC1810FET100 application, or LPC1810FET100 equivalent, key selection criteria include its TFBGA100 package with 49 GPIOs, absence of USB/Ethernet/LCD blocks, 10-bit dual ADC (4 channels total), and support for external memory via EMC - critical for resource-constrained embedded designs needing peripheral flexibility without feature bloat.

Technical Context

The LPC1810FET100 implements an ARM Cortex-M3 r2p1 core with Harvard architecture, 3-stage pipeline, and integrated MPU supporting eight memory regions. Its clock system includes three PLLs: one for CPU operation up to 180 MHz, one dedicated to audio, and one unused in this variant due to missing USB/USB PHY blocks.

Digital peripherals are constrained per Table 2: no C_CAN controllers, no motor control PWM, no QEI, and only four ADC input channels shared across two 10-bit ADCs. The External Memory Controller supports SRAM, NOR flash, and SDRAM but excludes SDRAM refresh control in this configuration.

FAQ

What is the maximum operating frequency of the LPC1810FET100?

The LPC1810FET100 operates at a maximum CPU frequency of 180 MHz using its ARM Cortex-M3 core. This speed is achieved via an internal PLL that multiplies the input crystal or RC oscillator frequency, and it remains stable across the full industrial temperature range (-40°C to +85°C) under specified supply conditions.

Does the LPC1810FET100 include onboard flash memory?

No, the LPC1810FET100 is a flashless microcontroller. It relies entirely on external memory - either through the Quad SPI Flash Interface (SPIFI) or the External Memory Controller (EMC) - for program storage. Boot code resides in 64 kB ROM, and 64-bit + 256-bit OTP memory is available for calibration or security keys.

How many ADC channels does the LPC1810FET100 support?

The LPC1810FET100 integrates two 10-bit ADCs with a combined total of four input channels. These are shared between ADC0 and ADC1, with each channel (e.g., ADC0_0 and ADC1_0) tied together on dedicated pins - limiting simultaneous independent sampling but enabling redundancy or differential configurations.

Is the LPC1810FET100 pin-compatible with other LPC18xx variants in TFBGA100?

Yes, the LPC1810FET100 shares the same TFBGA100 pinout (SOT926-1) with LPC1820FET100 and LPC1830FET100. All functions mapped to physical balls are identical; however, unused peripherals (e.g., USB, Ethernet) are disabled in silicon and do not affect pin behavior or electrical characteristics.

What debug interfaces are supported by the LPC1810FET100?

The LPC1810FET100 supports JTAG and Serial Wire Debug (SWD) interfaces, along with serial trace output. It includes eight hardware breakpoints, four watchpoints, and full support for the Enhanced Trace Module (ETM) and Enhanced Trace Buffer (ETB), enabling cycle-accurate instruction tracing and real-time variable monitoring during development.
