The 8-channel 12-bit ADC and single 10-bit DAC cover analog sensing and setpoint output. Brown-out detect, POR, and watchdog keep the system alive in noisy industrial environments.
Rated -40 to 85 °C, suited for factory automation, outdoor telecom cabinets, and engine-bay controllers. Housed in 100-LQFP (14x14 mm) with 70 I/O.
Pin-compatible siblings in the LPC17xx family include the LPC1768 and LPC1769, which share the same 100-LQFP footprint, Cortex-M3 core, and Ethernet peripheral. The main difference is Flash density — the LPC1768 carries 512 KB, while the LPC1769 offers 512 KB or higher options.
The core runs at 100 MHz. That is the maximum CPU clock for this Cortex-M3 device.
