Freescale Semiconductor, Inc...
16K BYTES INTEGRATED SECOND-GENERATION 0.35碌 FLASH MEMORY
The 68HC908JB16 is an upwardly compatible,
versatile migration from Motorola鈥檚 68HC908JB8
universal serial bus (USB) microcontroller unit
(MCU). The innovative design features an
on-chip USB module for fast, reliable PC
peripheral applications, and dual 27 MHz
clock generators. An energy-saving, low-power
solution, the 68HC908JB16 is embedded with
16 Kbytes of Motorola鈥檚 second-generation FLASH
technology to enable in-system programmability.
鈥?In-application re-programmable
鈥?Extremely fast programming, encoding 64
bytes in as fast as 32 碌sec per byte
鈥?FLASH programming across the 68HC08
device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?Helps to reduce production programming
costs through ultra-fast programming
鈥?Byte-writable for data as well as
program memory
鈥?Helps protect code from unauthorized
reading and guards against unintentional
erasing/writing of user-programmable
segments of code
