General Description
– 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
