Section 1 Introduction
1.1 Overview
The MC9S12C-Family and the MC9S12GC-Family is a 48/52/80 pin Flash-based Industrial/Automotive
network control MCU family. Members of the MC9S12C-Family and the MC9S12GC-Family deliver the
power and flexibility of our 16 Bit core (CPU12) family to a whole new range of cost and space sensitive,
general purpose Industrial and Automotive network applications. All MC9S12C-Family and
MC9S12GC-Family members are comprised of standard on-chip peripherals including a 16-bit central
processing unit (CPU12), up to 128K bytes of Flash EEPROM, up to 4K bytes of RAM, an asynchronous
serial communications interface (SCI), a serial peripheral interface (SPI), an 8-channel 16-bit timer
module (TIM), a 6-channel 8-bit Pulse Width Modulator (PWM), an 8-channel, 10-bit analog-to-digital
converter (ADC). The MC9S12C-Family members also feature a CAN 2.0 A, B software compatible
module (MSCAN12). The MC9S12C-Family as well as the MC9S12GC-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 in each module, up to 10 dedicated I/O
port bits are available with Wake-Up capability from STOP or WAIT mode. The MC9S12C-Family and
the MC9S12GC-Family devices are available in 48, 52 and 80 pin QFP packages, with the 80 Pin version
pin compatible to the HCS12 A, B and D- Family derivatives.
