— External address space 1MByte for Data and Program space (112 pin package only)

— 8-bit port H

— 4-bit port J

— 8-bit port P shared with PWM

— 64K, 128K, 256K Byte Flash EEPROM

— 1K, 2K Byte EEPROM

— 2K, 4K and 8K Byte RAM

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.

Not all features listed here are available in all configurations.

Additional information about D and B family inter-operability is given in:

EB386 “HCS12 D-Family Compatibility Considerations” and

EB388 “Using the HCS12 D_Family as a development platform for the HCS12 B family”
