MC68HC908JB16单片机破解

MC68HC908JB16  Features：
• 8-MHz internal bus frequency
• Trimmable internal oscillator:
– 4.0 MHz internal bus operation
– 8-bit trim capability
– 25% untrimmed
– 5% trimmed
• 8 Kbytes of 10 K write/erase cycle typical on-chip in application programmable FLASH memory with security option(1)
• 128 bytes of on-chip random-access memory (RAM)
• Dual channel high resolution PWM with dead time insertion and shutdown input. The outputs use frequency dithering to achieve a 4 ns output resolution.
• Dual channel pulse-width modulator (PWM) module to provide power factor correction capability
• Seven channel, 8-bit successive approximation analog-to-digital converter (ADC)
• Op amp/comparator for power factor correction capability or general purpose use
• 7-bit keyboard interrupt
• One 16-bit, 2-channel timer interface module with one output available on port pin (PTA6) for input capture and PWM
• 17 general-purpose input/output (I/O) pins and one input only pin
– Three shared with high resolution PWM (HRP)
– Three shared with PWM module
– Three shared with op amp/comparator
– Seven shared with ADC module (AD[0:6])
– One shared with timer channel 0
– Two shared with OSC1 and OSC2
– One shared with reset
– Seven shared with keyboard interrupt
– One input-only pin shared with external interrupt (IRQ)
• Available packages:
– 20-pin small outline integrated chip (SOIC) package
– 20-pin plastic dual in-line package (PDIP)
• On-chip programming firmware for use with host personal computer which does not require high voltage for entry
• System protection features:
– Optional computer operating properly (COP) reset
– Low-voltage reset
– Illegal opcode detection with reset
– Illegal address detection with reset
• Low-power design; fully static with stop and wait modes
