NXP  MCHC912B32CFUE8  芯片, 16位微控制器, 32K闪存, 1K RAM

The is a 16-bit Microcontroller composed of standard on-chip peripherals including a 16-bit central processing unit CPU12, 32kB flash EEPROM, 1kB RAM, 768-byte EEPROM, an asynchronous serial communications interface SCI, a serial peripheral inter-face SPI, an 8-channel timer and 16-bit pulse accumulator, a 10-bit analog-to-digital converter ADC, a four-channel pulse-width modulator PWM and a J1850-compatible byte data link communications module BDLC. The chip is the first 16-bit microcontroller to include both byte-erasable EEPROM and flash EEPROM on the same device. System resource mapping, clock generation, interrupt control and bus interfacing are managed by the lite integration module LIM. The device has full 16-bit data paths throughout, however, the multiplexed external bus can operate in an 8-bit narrow mode so single 8-bit wide memory can be interfaced. for lower cost systems.
