MC9S12DT256B : 16-Bit Microcontroller
The MC9S12DT256B 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 MC9S12DT256B 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 user
guides, download the ZIP file.
