Overview
The MC9S12A64 Flash microcontroller (MCU)
is the next generation of the highly successful
68HC12 architecture. Utilizing Freescale’s
industry-leading 0.25µ Flash, the A64 is part of
a pin-compatible family that is planned to scale
from 32 KB to 512 KB of Flash memory. The
MC9S12A64 provides an upward migration
path from Freescale’s 68HC08, 68HC11 and
68HC12 architectures for applications that
need larger memory, more peripherals and
higher performance.

at full speed
Integrated Third-Generation Flash Memory
> In-application reprogrammable
> Self-timed, fast programming
• Fast Flash page erase—20 ms (512 bytes)
• Can program 16 bits in 20 µs while in
burst mode
> 5V Flash program/erase/read
> Flash granularity—512 byte Flash erase/2 byte
Flash program
> Flexible block protection and security
> Flexibility to change code in the field
> Efficient end-of-line programming
> Total program time for 164 KB code is less
than 5s
> Reduces production programming cost
through ultra-fast programming
> No external high voltage or charge
pump required
> Virtual EEPROM implementation, Flash array
usable for EE extension
1 KB Integrated EEPROM
> Flexible protection scheme for protection
against accidental program or erase
> EEPROM can be programmed in 46 µs
> Can erase 4 bytes at a time and program
2 bytes at a time for calibration, security,
personality and diagnostic information
10-bit Analog-to-Digital Converter (ADC)
> Two eight-channel ADCs
> 7 µs, 10-bit single conversion time, scan
mode available
> Fast, easy conversion from analog inputs,
such as position sensors, analog meters
and photovoltaic cells, to digital values for
CPU processing
> Can effectively have 3.5 µs conversion
time by sampling same signal with
both ADCs
Clock Generation Module with Phase-Lock Loop (PLL)
> Clock monitor with limp home mode in case of
no external clock
> Programmable clock frequency with 1,024
options ranging from divide by 16 to multiply
by 64 form base oscillator
> Real-time interrupt
>
Watchdog
> Reliable, robust operation
>
