32-bit RISC microcontroller featuring an ARM7 CPU operating at up to 55MHz. This FLASH-programmable device offers 524,288 words of ROM and 32,768 bytes of RAM. It includes 88 I/O lines, a 32-bit external data bus, and a 23-bit address bus. The industrial-grade component operates within a -40°C to 85°C temperature range and requires a 1.8V nominal supply voltage (1.65V to 1.95V). Packaged in a 128-terminal PQFP (LQFP-128), it supports PWM channels, ADC, and DMA channels.
