Precision Analog Microcontroller featuring an ARM7TDMI core operating at up to 41.78MHz. This 16-bit MCU integrates a 12-bit ADC with 10 channels and a 12-bit DDS DAC, offering a 1MS/s sampling rate. On-chip memory includes 126KB FLASH and 8KB RAM, supported by peripherals like POR, PWM, WDT, and a temperature sensor. Connectivity is provided via I2C (2 channels), SPI (1 channel), and UART/USART (2 channels), with 28 I/Os and 40 programmable I/Os. Housed in an LQFP package for surface mounting, it operates from 3V to 3.6V with a maximum power dissipation of 135mW and a temperature range of -40°C to 125°C.
