TECHNICAL DATA

MC9S12B-Family

PRODUCT BRIEF

16-Bit Microcontroller

Designed for automotive multiplexing applications, members of the MC9S12B-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 MC9S12B-Family members are composed of standard

on-chip peripherals including a 16-bit central processing unit (CPU12), up to 256K bytes of Flash

EEPROM, 8K bytes of RAM, 2K bytes of EEPROM, two asynchronous serial communications

interfaces (SCI), serial peripheral interface (SPI), an input capture/output compare timer (TIM), 16-

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

CAN 2.0 A, B software compatible module (MSCAN12) and an Inter-IC Bus. System resource mapping,

clock generation, interrupt control and bus interfacing are managed by the lite integration module (LIM).

The MC9S12B-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

Wake-Up capability from STOP or WAIT mode.
