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
(I
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.
The MC68HC912DG128A device is similar to the MC68HC912DT128A,
but it has only two MSCAN12 modules. The entire databook applies also
to the MC68HC912DG128A, except where differences are noted.
