1 Introduction
The new MC9S12XE Family of microcontrollers takes the
innovation of today’s MC9S12XD Family a step further with
the introduction of new features to deliver enhanced system
integrity and greater functionality. These new features include
a Memory Protection Unit (MPU) and Error Correction Code
(ECC) on the Flash memory together with enhanced

EEPROM functionality (EEE), an enhanced XGATE, a
Frequency Modulated Phase Locked Loop (IPLL) and a faster
ATD. The E Family will extend the S12X product range up to
1MB of Flash memory with increased I/O capability in the
208-pin version of the flagship MC9S12XEP100.

Critical Performance
Targeted at automotive multiplexing and generic auto body
applications, S12XE Family will deliver 32-bit performance
with all the advantages and efficiencies of a 16-bit MCU. It
will retain the low cost, power consumption, EMC and code-
size efficiency advantages currently enjoyed by users of
Freescale’s existing 16-bit S12 and S12X MCU families.
There is a high level of compatibility between the S12XE and
S12XD families.

Like members of other S12X families, the S12XE Family will
run 16-bit wide accesses without wait states for all peripherals
and memories.
The S12XE Family features an enhanced version of the
performance-boosting XGATE co-processor which is
programmable in “C” language and runs at twice the bus
frequency of the S12X with an instruction set optimized for
