PIC16C717/770/771 Datasheet (4/1/2003)

Microcontroller Core Features:
• High-performance RISC CPU
• Only 35 single word instructions to learn
• All single cycle instructions except for program
branches which are two cycle
• Operating speed: DC - 20 MHz clock input
DC - 200 ns instruction cycle
nterrupt capability (up to 10 internal/external
interrupt sources)
• Eight level deep hardware stack
• Direct, indirect and relative addressing modes
• Power-on Reset (POR)
• Power-up Timer (PWRT) and
Oscillator Start-up Timer (OST)
• Watchdog Timer (WDT) with its own on-chip RC
oscillator for reliable operation
• Selectable oscillator options:
- INTRC - Internal RC, dual speed (4 MHz and
37 kHz nominal) dynamically switchable for
power savings
- ER - External resistor, dual speed (user
selectable frequency and 37 kHz nominal)
dynamically switchable for power savings
- EC - External clock
- HS - High speed crystal/resonator
- XT - Crystal/resonator
- LP - Low power crystal
• Low power, high speed CMOS EPROM
technology
• In-Circuit Serial Programming™ (ICSP™)
• Wide operating voltage range: 2.5V to 5.5V
• 15 I/O pins with individual control for:
- Direction (15 pins)
- Digital/Analog input (6 pins)
- PORTB interrupt on change (8 pins)
- PORTB weak pull-up (8 pins)
- High voltage open drain (1 pin)
• Commercial and Industrial temperature ranges
• Low power consumption:
- < 2 mA @ 4V, 4 MHz
-11 µA typical @ 2.5V, 37 kHz
-< 1 µA typical standby current
Peripheral Features:
• 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

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
- Enhanced PWM:
- Single, Half-Bridge and Full-Bridge Output
modes
- Digitally programmable deadband delay
• Analog-to-Digital converter:
- PIC16C770/771 12-bit resolution
- PIC16C717 10-bit resolution
• On-chip absolute bandgap voltage reference
generator
• Programmable Brown-out Reset (PBOR)
circuitry
• Programmable Low-Voltage Detection (PLVD)
circuitry
• Master Synchronous Serial Port (MSSP) with two
modes of operation:
-3-wire SPI™ (supports all 4 SPI modes)
-I
2C™ compatible including Master mode
support
• Program Memory Read (PMR) capability for look-
up table, character string storage and checksum
calculation purposes
