TARGET APPLICATIONS
• 25 MHz bus operation at 5 V for 40 nsec
minimum instruction cycle time
• 16 MHz bus operation at 3.3 V for 62.5
nsec minimum instruction cycle time
• Opcode compatible with the 68HC11
and 68HC12
•C optimized architecture produces
extremely compact code
HIGH-PERFORMANCE 16-BIT HCS12 CPU CORE
ON-CHIP DEBUG INTERFACE
DIGITAL-TO-ANALOG CONVERTER
• Single-wire background debug mode
• On-chip trace buffer with nine flexible
trigger modes and multiple hardware
breakpoints
• Non-intrusive emulation
• Real-time emulation of MCU functions at
full operating voltage and frequency
range with no limitations like traditional
emulators
• Bus state analysis without the expense of
a traditional emulator
• Non-intrusive debugging through a single,
dedicated pin helps eliminate the need
and cost of cumbersome emulator cables
•View and change internal registers and
memory while running application
INTEGRATED THIRD-GENERATION FLASH MEMORY

FEATURES BENEFITS
A FLASH MCU SOLUTION
MC9S12E128/E64
16-bit Microcontroller
The HCS12 Family of microcontrollers
is the next generation of the highly
successful 68HC12 architecture. Utilizing
Motorola’s industry-leading 0.25µ Flash,
the E128 is part of a pin-compatible
family that is planned to scale from
32 Kbytes to 512 Kbytes of Flash
memory. The E128 provides an upward
migration path from Motorola’s 68HC08,
68HC11 and 68HC12 architectures
for applications that need larger
memory, more peripherals and
higher performance.
