Freescale Semiconductor, Inc...
The 68HC908AB32 FLASH microcontroller
utilizes Motorola鈥檚 highly successful 68HC08
architecture and is code compatible with
68HC05 microcontrollers providing an efficient
migration path to higher performance FLASH
MCUs. With 32,256 bytes of in-system,
programmable FLASH memory and in-circuit
programming capability, the 68HC908AB32
delivers high-performance while lowering
costs. The 68HC908AB32 provides security
and reliability with innovative features like a
computer operating properly (COP) watchdog,
selectable FLASH security, memory-mapped
input/output registers, low-voltage inhibit
(LVI) and stop and wait modes.
INTEGRATED SECOND GENERATION FLASH MEMORY
鈥?In-application re-programmable
鈥?Extremely fast programming, encoding
64 bytes in as fast as 2 msec
鈥?FLASH programming across the 68HC08鈥檚
full operating supply voltage with no extra
programming voltage
鈥?10K write/erase cycles minimum over
temperature
鈥?Flexible block protection and security
鈥?Cost-effective programming changes and
field software upgrades via in-application
programmability and re-programmability
鈥?Reduces production programming costs
through ultra-fast programming
鈥?Allows re-programmable battery-powered
applications
鈥?Byte-writable for data as well as program
memory
鈥?Protects code from unauthorized reading and
to guard against unintentional
erasing/writing of user-programmable
segments of code
