Features

2.7 V to 5.5 V operation
32 K bytes of on-chip EPROM/ROM program memory
1024 bytes of on-chip data RAM
Supports off-chip addressing up to 16 megabytes (24 address lines)
Clock output reference is added to simplify external bus interfacing
High performance 8-channel 8-bit A/D converter with automatic channel scan and repeated read functions:
- Completes a conversion in 4.46 microseconds at 30 MHz
- Alternate operating mode allows 10‑bit conversion results
Three standard counter/timers with enhanced features:
- All timers have a toggle output capability
Watchdog timer
5-channel 16-bit Programmable Counter Array (PCA)
I²C-bus serial I/O port with byte-oriented controller and target functions
Two enhanced UARTs with independent baud rates
Seven software interrupts
Active low reset output pin indicates all reset occurrences (external reset, watchdog reset and the RESET instruction):
- A reset source register allows program determination of the cause of the most recent reset
50 I/O pins, each with 4 programmable output configurations
30 MHz operating frequency at V_DD = 2.7 V to 5.5 V
Power saving operating modes:
- Idle
- Power-down
Wake-up from power-down via an external interrupt is supported
68-pin PLCC and 80-pin PQFP packages
