Benefits
Excellent System Performance: Increased
CPUbusfrequencyupto50MHz;withCPU
throughput benefiting from the enhanced
XGATE coprocessor performance
Scalability and Compatitbility: Extends
S12X memory size up to 1 MB, providing an
upgrade path for the S12XD family
Higher System Integrity: At the MCU level
from features such as the ECC Supervisor
Mode and the MPU which eases AUTOSAR
integration
Flexibility:Supportscustomerrequirements,
with high memory, enhanced ATD and a large
number of peripherals and
packaging options
Development Support:Leveragesand
expands on the extensive suite of hardware
and software development tools available
today from the S12 and S12XD family
