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

erasing/writing of user-programmable
segments of code
The 68HC908JL3, the 68HC908JK3 and the
68HC908JK1 utilize a 68HC08 CPU core and
provide cost-effective re-programmable
FLASH with an integrated analog-to-digital
converter (ADC). This family also includes
multiple clock options, two 16-bit timer
channels, low voltage inhibit (LVI) and a
watchdog timer.
