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 Represen tative 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 • 2K x 14 words of Program Memory, 128 x 8 bytes of Data Memory (RAM) • Interrupt capability • 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 • Brown-out detection circuitry for Brown-out Reset (BOR) • Programmable code-protection • Power saving SLEEP mode • Selectable oscillator options • Low-power, high-speed CMOS EPROM technology • Fully static design • In-Circuit Serial Programming (ICSP) • Wide operating voltage range: 2.5V to 5.5V • High Sink/Source Current 25/25 mA • Commercial, Industrial and Extended 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 • Capture, Compare, PWM module • Capture is 16-bit, max. resolution is 12.5 ns, Compare is 16-bit, max. resolution is 200 ns, PWM maximum resolution is 10-bit • 8-bit multi-channel Analog-to-Digital converter • Synchronous Serial Port (SSP) with Enhanced SPI and I2C
