branches, which are two-cycle
• Operating speed: DC - 20 MHz clock input
DC - 200 ns instruction cycle
• 2K x 14 words of FLASH Program Memory
• 128 bytes of Data Memory (RAM)
• 64 bytes of EEPROM Data Memory
• Pinout compatible to the PIC16C72A
• Interrupt capability (up to 10 sources)
• Eight level deep hardware stack
• Direct, Indirect and Relative Addressing modes
Peripheral Features:
• High Sink/Source Current: 25 mA
• Timer0: 8-bit timer/counter with 8-bit prescaler
• Timer1: 16-bit timer/counter with prescaler,
can be incremented during SLEEP via external
crystal/clock
• Timer2: 8-bit timer/counter with 8-bit period
register, prescaler and postscaler
• One Capture, Compare, PWM module
- Capture is 16-bit, max. resolution is 12.5 ns
- Compare is 16-bit, max. resolution is 200 ns
- PWM max. resolution is 10-bit
• 10-bit, 5-channel Analog-to-Digital converter (A/D)

Brown-out Reset (BOR)
CMOS Technology:
• Low power, high speed CMOS FLASH/EEPROM
technology
• Wide operating voltage range: 2.0V to 5.5V
• Fully static design
• Commercial, Industrial and Extended temperature
ranges
• Low power consumption:
- < 2 mA typical @ 5V, 4 MHz
- 20 μA typical @ 3V, 32 kHz
- < 1 μA typical standby current
