PIC16C71

The PIC16C71X is a family oflow-cost, high-performance,CMOS, fully-static, 8-bit microcontrollers withintegrated analog-to-digital (A/D) converters, in thePIC16CXX mid-range family.

All PIC16/17 microcontrollers employ an advancedRISC architecture. The PIC16CXX microcontroller familyhas enhanced core features, eight-level deep stack,and multiple internal and external interrupt sources.The separate instruction and data buses of the Harvardarchitecture allow a 14-bit wide instruction word withthe separate 8-bit wide data. The two stage instructionpipeline allows all instructions to execute in a singlecycle, except for program branches which require twocycles. A total of 35 instructions (reduced instructionset) are available. Additionally, a large register set givessome of the architectural innovations used to achieve avery high performance.

PIC16CXX microcontrollers typically achieve a 2:1code compression and a 4:1 speed improvement overother 8-bit microcontrollers in their class.

ThePIC16C710/71devices have 36 bytes of RAM, thePIC16C711has 68 bytes of RAM and thePIC16C715has 128 bytes of RAM. Each device has 13 I/O
pins. Inaddition a timer/counter is available. Also a 4-channelhigh-speed 8-bit A/D is provided. The 8-bit resolution isideally suited for applications requiring low-cost analoginterface, e.g. thermostat control, pressure sensing,etc.

The PIC16C71X family has special features to reduceexternal components, thus reducing cost, enhancingsystem reliability and reducing power consumption.There are four oscillator options, of which the single pinRC oscillator provides a low-cost solution, the LP oscillatorminimizes power consumption, XT is a standardcrystal, and the HS is for High Speed crystals. TheSLEEP (power-down) feature provides a power savingmode. The user can wake up the chip from SLEEPthrough several external and internal interrupts andresets.

A highly reliable Watchdog Timer with its own on-chipRC oscillator provides protection against software lockup.

A UV erasable CERDIP packaged version is ideal forcode development while the cost-effective One-Time-Programmable (OTP) version is suitable for productionin any volume.

The PIC16C71X family fits perfectly in applicationsranging from security and remote sensors to appliancecontrol and automotive. The EPROM technologymakes customization of application programs (transmittercodes, motor speeds, receiver frequencies, etc.)extremely fast and convenient. The small footprintpackages make this microcontroller series perfect forall applications with space limitations. Low cost, lowpower, high performance, ease of use and I/O flexibilitymake the PIC16C71X very versatile even in areaswhere no microcontroller use has been consideredbefore (e.g. timer functions, serial communication, captureand compare, PWM functions and coprocessorapplications).
