– 0 to 33 MHz with 12-clock operation
• Parallel programming with 87C51 compatible hardware interface
to programmer
• RAM expandable externally to 64 kbytes
• Programmable Counter Array (PCA)
– PWM
– Capture/compare
• PLCC, LQFP, or DIP package

– Automatic address recognition
• Three 16-bit timers/counters T0, T1 (standard 80C51) and
additional T2 (capture and compare)
• Programmable clock-out pin
• Asynchronous port reset
• Low EMI (inhibit ALE, slew rate controlled outputs,
and 6-clock mode)
• Wake-up from Power Down by an external interrupt
