S12B MCUs|16-bit Microcontroller

For best experience this site requires Javascript to be enabled. To enable on your browser, follow our accessibility instructions.

Designed for automotive multiplexing applications, members of the MC9S12B family of 16- bit flash-based MCUs are fully pin compatible, allowing you to choose between different memory and peripheral options for scalable designs.

The S12B MCU manages the following via a lite integration module (LIM):

System resource mapping
Clock generation
Interrupt control
Bus interfacing

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.

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.
