Section 1 Introduction
1.1 Overview
The MC9S12E-Family is a 112/80 pin low cost general purpose MCU family. All members of the
MC9S12E-Family are comprised of standard on-chip peripherals including a 16-bit central processing unit
(HCS12 CPU), up to 256K bytes of Flash EEPROM, up to 16K bytes of RAM, three asynchronous serial
communications interface modules (SCI), a serial peripheral interface (SPI), an Inter-IC Bus (IIC), three
4-channel 16-bit timer modules (TIM), a 6-channel 15-bit Pulse Modulator with Fault protection module
(PMF), a 6-channel 8-bit Pulse Width Modulator (PWM), a 16-channel 10-bit analog-to-digital converter
(ADC), and two 1-channel 8-bit digital-to-analog converters (DAC). The MC9S12E-Family has full 16-bit
data paths throughout. 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 on each module, 16
dedicated I/O port bits are available with Wake-Up capability from STOP or WAIT mode. Furthermore,
an on chip bandgap based voltage regulator (VREG) generates the internal digital supply voltage of 2.5V
(VDD) from a 3.135V to 5.5V external supply range.
