PIC17C762-16E/PT - 8-Bit 16MHz 16KB OTP MCU 80-TQFP | Microchip
MPN: PIC17C762-16E/PT ✓ פעילPIC17C762-16E/PT סקירה
An 8-bit microcontroller (MCU) is a small computer-on-a-chip integrating an 8-bit CPU core, program memory, data RAM, and peripheral subsystems on a single silicon die. It belongs to the broader hierarchy of microcontrollers -> embedded processors -> integrated circuits -> semiconductors, and is the workhorse of industrial control, automotive body electronics, and consumer appliances where deterministic real-time response and cost efficiency matter more than raw compute.
Key features of the PIC17C762-16E/PT include 66 digital I/O pins, integrated Brown-out Detect/Reset, Power-On Reset (POR), Pulse-Width Modulation (PWM) outputs, and a Watchdog Timer (WDT). The wide 66-I/O count makes it well-suited to driving multiple sensors, keypads and actuators in a single chip without external expanders. The OTP program memory offers one-time field programmability, suiting mature production runs where code is fixed.
Architecturally, the PIC17C762 uses Microchip's enhanced Harvard architecture with separate program and data buses, allowing instruction fetch and operand access in the same cycle. The 16-bit wide program word (8K x 16 = 16KB) gives each instruction more headroom than 14-bit PIC16 cores, while the RISC instruction set simplifies compiler code generation. Supply voltage is 4.5V to 5.5V and the -E suffix denotes the extended industrial temperature grade of -40C to +125C.
Typical applications include industrial automation controllers, automotive body and chassis subsystems, HVAC control, uninterruptible power supply (UPS) front panels, and consumer appliances with rich I/O. Microchip's own product page recommends considering the PIC18F8520 as a newer flash-based alternative for new designs, but the PIC17C762 family remains supported for legacy systems.
Designers should note that this part is OTP, not flash-based, so firmware must be fully verified before programming. The 80-pin TQFP footprint requires careful PCB layout with adequate thermal relief and four-layer routing for the high pin count. Review Microchip's PIC17C76x Family datasheet for oscillator, A/D and USART configurations before committing to the design.

יישומים טיפוסיים
PIC17C762-16E/PT מתאים עבור 6 יישוםs: Industrial Automation Controllers, Automotive Body Electronics, Uninterruptible Power Supply (UPS) Front Panel, HVAC Climate Control Systems, Consumer Appliance Control Boards, Point-of-Sale (POS) Terminals and Printers.
Industrial Automation Controllers
The PIC17C762-16E/PT's 66 I/O pins, 8.25 MIPS throughput and -40C to +125C extended temperature grade make it well-suited to industrial PLC and machine-controller boards. The 16 KB OTP stores ladder-logic-style control firmware, while the integrated PWM and Brown-out Reset directly drive motor-speed references and protect the MCU from supply transients on noisy factory buses.
מומלץ
Automotive Body Electronics
The PIC17C762-16E/PT's extended -40C to +125C temperature range, 66 I/O and Watchdog Timer support deployment in automotive body and chassis modules such as instrument clusters, HVAC panels and central locking controllers. The Brown-out Detect/Reset prevents undefined behaviour during cranking voltage dips, while the OTP memory suits high-volume fixed-code body ECUs where cost dominates.
מומלץ
Uninterruptible Power Supply (UPS) Front Panel
The PIC17C762-16E/PT's 66 I/O and integrated PWM are well-matched to UPS front-panel and battery-management controllers. Multiple GPIO scan LED/LCD status indicators, while the PWM channel drives the audible alarm and fan-speed control. The PIC17C RISC 121 ns instruction cycle ensures deterministic response to AC-line fault interrupts before the battery inverter takes over.
מומלץ
HVAC Climate Control Systems
The PIC17C762-16E/PT's extended temperature grade suits the under-roof thermal environment of HVAC equipment. Its 66 I/O drive keypad inputs, multiplexed seven-segment or LCD displays, triac-fired fan/coil outputs and NTC thermistor feedback inputs. The integrated WDT recovers from firmware lockup in unattended installations, while 16 KB OTP holds the heating/cooling control algorithm.
מומלץ
Consumer Appliance Control Boards
The PIC17C762-16E/PT offers washing machines, dishwashers and microwave ovens a high-I/O-count 8-bit controller with mature toolchain support. The 8.25 MIPS throughput runs motor-control state machines, while 16 KB OTP holds fixed-function appliance firmware at low unit cost. Brown-out Reset and WDT survive the noisy switching environment of universal-motor and triac drive stages.
מומלץ
Point-of-Sale (POS) Terminals and Printers
The PIC17C762-16E/PT's 66 I/O and 16 KB OTP program memory serve as the main controller in POS terminals, receipt printers and barcode scanners. Multiple USART channels drive the scanner, printer and cash-drawer peripherals, while the integrated PWM modulates the piezo buzzer. The 80-pin TQFP package provides plenty of I/O for keypad matrix scanning and dual-line LCD driving.

מבדילים עיקריים
- Highest temperature grade in the PIC17C762 family (לעומתPIC17C762-16I/PT)
- OTP memory enables lower unit cost than flash equivalents at high volume (לעומתPIC18F8520)
- Higher I/O count than typical 8-bit PIC16 MCUs (לעומתPIC16F877A-I/PT (40-pin DIP))
הערות תכנון
The PIC17C762-16E/PT uses One-Time-Programmable (OTP) memory, not flash. Firmware must be fully validated before programming because the device cannot be erased or rewritten. A single bad bit means scrapping the silicon. For field-updateable designs, choose the flash-based PIC18F8520 instead.
The 80-pin TQFP (12x12 mm) with 0.5 mm pitch requires four-layer PCB with fine-pitch soldering. Place 0.1 uF decoupling capacitors close to every Vdd/Vss pair (there are four pairs per the datasheet). Provide a low-ESR bulk capacitor on each Vdd rail and keep the MCLR line short to avoid spurious resets from switching noise.
Route the OSC1/OSC2 traces short and symmetric. Use a crystal with appropriate load capacitance (typically 22-33 pF) and keep the trace impedance under 50 ohm where possible. Avoid routing high-speed switching signals (PWM outputs, oscillator) parallel to analog inputs to minimise cross-talk in mixed-signal control boards.
