Overview 

Device Introduction

The MC9S12C-Family / MC9S12GC-Family are 48/52/80 pin Flash-based MCU families, which deliver the power and flexibility 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.

Product Brief

16-Bit Microcontroller

Designed for automotive multiplexing applications, members of the MC9S12D-Family of 16 bit Flashbased

microcontrollers are fully pin compatible and enable users to choose between different memory

and peripheral options for scalable designs. All MC9S12D-Family members are composed of standard

on-chip peripherals including a 16-bit central processing unit (CPU12), up to 512K bytes of Flash

EEPROM, 14K bytes of RAM, 4K bytes of EEPROM, two asynchronous serial communications

interfaces (SCI), three serial peripheral interfaces (SPI), IIC-bus, an enhanced capture timer (ECT), two

8-channel 10-bit analog-to-digital converters (ADC), an eight-channel pulse-width modulator (PWM),

J1850 interface and up to five CAN 2.0 A, B software compatible modules (MSCAN12). System

resource mapping, clock generation, interrupt control and bus interfacing are managed by the system

integration module (SIM). The MC9S12D-Family 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 interrupt capability allowing Wake-Up from STOP or WAIT mode.
