MC9S12DP256B : 16-Bit Microcontroller
The MC9S12DP256B microcontroller unit (MCU) is a 16-bit device composed of standard on-chip
peripherals including a 16-bit central processing unit (HCS12 CPU), 256K bytes of Flash EEPROM,
12.0K bytes of RAM, 4.0K bytes of EEPROM, 2 asynchronous serial communications interfaces
(SCI), three serial peripheral interfaces (SPI), an 8 channel IC/OC enhanced capture timer, two 8-
channel, 10-bit analog-to-digital converters (ADC), an 8-channel pulse-width modulator (PWM), 89
discrete digital I/O channels (Port A, Port B, Port K and Port E), 20 discrete digital I/O lines with
interrupt and wakeup capability, five CAN 2.0 A, B software compatible modules (MSCAN12), and
an Inter-IC Bus.
System resource mapping, clock generation, interrupt control and bus interfacing are managed by
the System Integration Module (SIM). The MC9S12DP256B 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.
Note: documentation for this device has been structured in a modular form. For the complete set of
