1.2 Introduction
The MC68HC912DT128A microcontroller unit (MCU) is a 16-bit device
composed of standard on-chip peripherals including a 16-bit central
processing unit (CPU12), 128K bytes of flash EEPROM, 8K bytes of
RAM, 2K bytes of EEPROM, two asynchronous serial communications
interfaces (SCI), a serial peripheral interface (SPI), an inter-IC interface
(I²C), an enhanced capture timer (ECT), two 8-channel, 10-bit analog-
to-digital converters (ADC), a four-channel pulse-width modulator
(PWM), and three CAN 2.0 A, B software compatible modules
(MSCAN12). System resource mapping, clock generation, interrupt
control and bus interfacing are managed by the lite integration module
(LIM). The MC68HC912DT128A has full 16-bit data paths throughout,
however, the external bus can operate in an 8-bit narrow mode so single
8-bit wide memory can be interfaced for lower cost systems. The
inclusion of a PLL circuit allows power consumption and performance to
be adjusted to suit operational requirements. In addition to the I/O ports
available in each module, 16 I/O ports are available with Key-Wake-Up
capability from STOP or WAIT mode.
