The MC68HC912DG128 microcontroller unit (MCU) is a16-bit device
composed of standard on-chip peripherals including a 16-bit central
processing unit (CPU12), 128-Kbyte flash EEPROM, 8K byte RAM, 2K
byte EEPROM, two asynchronous serial communications interfaces
(SCI), a serial peripheral interface (SPI), an 8-channel, 16-bit timer,
two16-bit pulse accumulators and 16-bit down counter (ECT), two 10-bit
analog-to-digital converter (ADC), a four-channel pulse-width modulator
(PWM), an IIC interface module, and two MSCAN modules. 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 MC68HC912DG128 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.
