MC9S12C and MC9S12GC Device Overview (MC9S12C128)
1.1 Introduction
The MC9S12C-Family / MC9S12GC-Family are 48/52/80 pin Flash-based MCU families, which deliver
the power and ï¬exibility of the 16-bit core to a whole new range of cost and space sensitive, general
purpose industrial and automotive network applications. All MC9S12C-Family / MC9S12GC-Family
members feature 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 MC9S12C128-Family members also feature a CAN 2.0 A, B software compatible module
(MSCAN12).
All MC9S12C-Family / MC9S12GC-Family devices feature 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 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.
