Product Details

Description



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
• Standard low-power modes of operation:
Wait mode
Stop mode
• Master reset pin and power-on reset (POR)
• 674 bytes of FLASH programming routines read-only memory (ROM)
• Break module (BRK) to allow single breakpoint setting during in-circuit debugging
• Internal pullup on RST pin to reduce customer system cost
