Description
This powerful (200 nanosecond instruction execution) yet easy-to-program (only 35 single word instructions) CMOS OTP-based 8-bit microcontroller packs Microchip"s powerful PIC® architecture into an 20-pin package and is upwards compatible with the PIC16C5X and PIC12CXXX devices. The PIC16C771 features 6 channels of 12-bit Analog-to-Digital (A/D) converter giving designers the ability to discriminate smaller signal changes and eliminate the need for external circuitry for high precision measurement of analog signals. With 2 additional timers and an enhanced capture/compare/PWM function that make it ideal for the most sophisticated applications requiring higher levels of A/D in automotive, industrial, appliances and consumer applications.
• 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 (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 ?A typical @ 2.5V, 37 kHz – < 1 ?A typical standby current
