  • Not Recommended for New Designs
  • This page contains information on a product that is not recommended for new designs.

The MC9S12XB is a general-purpose optimized feature/cost family for applications that require a reduced peripheral relative to the S12XD family.

Targeted for general automotive body applications, the MC9S12XB family is a fully compatible subset of the 9S12XD family.

Relative to the S12XD family, it has some functionality removed and speed reduced in order to deliver a significant cost savings.

Like the S12XD family, the S12XB is designed to retain the cost-effective, low-power consumption, excellent electromagnetic compatibility performance and code-size efficiency advantages associated with all 16-bit MCUs from NXP®.

S12XB Family Members: MC9S12XB256, MC9S12XB128.
