Section 1 IntroductionMC9S12DT256
1.1 Overview
The MC9S12DT256 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, 12K
bytes of RAM, 4K bytes of EEPROM, two 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), a digital Byte Data Link
Controller (BDLC), 29 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, three CAN 2.0 A, B software compatible modules
(MSCAN12), and an Inter-IC Bus. The MC9S12DT256 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.
