Product Brief

MC9S12XD Family

16-bit Microprocessor Family (covers MC9S12XD64 through

MC9S12XDP512 and MC3S12XDT256/MC3S12XDG128)

Introduction

Targeted at automotive multiplexing applications, the MC9S12XD Family will deliver 32-bit performance

with all the advantages and efficiencies of a 16-bit MCU. The S12X is designed to retain the low cost, low

power consumption, excellent EMC performance and code-size efficiency advantages enjoyed by users

of Freescale's previous 16-bit MC9S12 MCU family.

Based around an enhanced S12 core, the MC9S12XD Family will deliver two to five times the

performance of a 25 MHz S12 whilst retaining a high degree of pin and code compatibility with the original

S12D - family.

The MC9S12XD Family features the performance boosting XGATE co-processor. The XGATE, which is

programmable in "C" language, has an instruction set which is optimized for data movement, logic and

bit manipulation instructions. It runs at twice the bus frequency of the S12X and off-loads the CPU by

providing high speed data transfer (and data processing) between any peripheral module, RAM and I/O

ports. This is particularly useful in applications such as automotive gateways where there are multiple

busses carrying heavy data traffic which would otherwise exert a heavy interrupt/processing load on the

CPU.
