The new MC9S12XE Family of microcontrollers will take the
innovation of today’s S12XD-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 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 MC9S12XE100.
Targeted at automotive multiplexing and generic auto body
applications, MC9S12XE-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 MC9S12 and S12X MCU families. There is a high level of
compatibility between the S12XE and S12XD families. The S12XS
family provides an economical, compatible extension to the S12XE
Family.
