Freescale Semiconductor, Inc...
The 68HC908GP32 and 68HC908GP16 are fully
integrated microcontrollers created to make
system design easier by eliminating external
peripherals wherever possible. The 32 kHz
phase-locked loop eliminates the need for
expensive, high-speed crystals or noisy
oscillators. The integrated second generation
FLASH memory programs up to 100 times
faster than prior FLASH solutions and offers
in-application programming. Features include
an asynchronous serial peripheral interface
(SPI), an asynchronous serial communications
interface (SCI), an analog-to-digital converter
(ADC), an auto wakeup from stop feature,
low-voltage inhibit (LVI) and a watchdog timer.
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
