Section 1 Introduction
1.1 Overview
The MC9S12DJ64 microcontroller unit (MCU) is a 16-bit device composed of standard on-chip
peripherals including a 16-bit central processing unit (HCS12 CPU), 64K bytes of Flash EEPROM, 4K
bytes of RAM, 1K bytes of EEPROM, two asynchronous serial communications interfaces (SCI), one
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, a CAN 2.0 A, B software compatible modules
(MSCAN12), and an Inter-IC Bus. The MC9S12DJ64 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.
