Section 1 Introduction
1.1 Overview
The MC9S12B128 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, 4K bytes
of RAM, 1K bytes of EEPROM, two asynchronous serial communications interfaces (SCI), serial
peripheral interface (SPI), an input capture/output compare timer (TIM), 16- channel, 10-bit
analog-to-digital converter (ADC), an 8-channel pulse-width modulator (PWM), one CAN 2.0 A, B
software compatible module (MSCAN12) and an Inter-IC Bus. The MC9S12B128 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, up to 22 I/O ports are available with Wake-Up capability from STOP or WAIT
mode.
