MC9S12D-Family

Product Brief

16-Bit Microcontroller

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

based 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.
