DEVICE OVERVIEW This document contains device-specific information. Additional information may be found in the PICmicro™ Mid-Range Reference Manual, (DS33023), which may be obtained from your local Microchip Sales Representative or downloaded from the Microchip website. The Reference Manual should be considered a complementary document to this data sheet, and is highly recommended reading for a better understanding of the device architecture and operation of the peripheral modules. 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 • Interrupt 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 (4MHz and 37KHz) dynamically switchable for power savings - ER - External resistor, dual speed (user selectable frequency and 37KHz) 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™ (ISCP) • 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 @ 5V, 4 MHz - 22.5 µA typical @ 3V, 32 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 • Enhanced Capture, Compare, PWM (ECCP) 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) - I2C™ compatible including master mode support • Program Memory Read (PMR) capability for look up table, character string storage and checksum calculation purposes
