PIC17C762-16E/PT 개요
The Microchip Technology PIC17C762-16E/PT is a high-performance 8-bit CMOS microcontroller from the PIC17C family, offering 16MHz maximum operating frequency, 16KB (8K x 16) of One-Time-Programmable (OTP) program memory and 678 bytes of general-purpose RAM, all housed in an 80-pin TQFP (12x12 mm) surface-mount package. It delivers 8.25 MIPS throughput (121 ns single-cycle instruction execution) across 58 single-word instructions, while program branches and table reads/writes take two cycles.
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.
This page synthesises distributor stock levels, drop-in alternatives and practical design notes that go beyond the manufacturer datasheet, giving engineers a single page to evaluate sourcing, replacement and qualification decisions.

Both share identical 16 MHz core, 16 KB OTP and 80-pin TQFP package, making them pin-compatible drop-in alternatives. Choose the -E grade for automotive and outdoor applications.
Can the PIC18F8520 replace the PIC17C762-16E/PT in an existing design?
The PIC18F8520 is Microchip's recommended newer replacement for the PIC17C76x family, offering flash memory instead of OTP, but it is NOT a drop-in replacement. The PIC18F8520 uses an 80-pin TQFP with a different pinout, requires different oscillator configuration and different programming tools. A board respin is required to migrate.
What is the best drop-in replacement for the PIC17C762-16E/PT?
The best drop-in replacement for the PIC17C762-16E/PT is the PIC17C762-16I/PT, which shares the same 80-pin TQFP (12x12 mm) footprint, same 16 MHz core, same 16 KB OTP memory and same 66 I/O pin count. The only meaningful difference is the industrial -40 C to +85 C temperature grade instead of the extended -40 C to +125 C grade of the -E variant.
What are the key specifications of the PIC17C762-16E/PT that engineers should know?
The PIC17C762-16E/PT is a Microchip 8-bit PIC17C family MCU: 16 MHz core (8.25 MIPS, 121 ns instruction cycle), 16 KB OTP program memory organised as 8K x 16, 678 bytes RAM, 66 digital I/O pins, supply voltage 4.5 V to 5.5 V, 80-pin TQFP (12x12 mm) package, -40 C to +125 C extended temperature grade, integrated Brown-out Reset, POR, PWM and Watchdog Timer. The 58 single-word RISC instruction set simplifies development.
Is the PIC17C762-16E/PT the same as the PIC18F8520?
No, the PIC17C762-16E/PT and PIC18F8520 are different MCU families. The PIC17C762-16E/PT is an 8-bit OTP PIC17C family part with 16 KB one-time-programmable memory, while the PIC18F8520 is an 8-bit flash-based PIC18 family part with more memory and peripherals. They are NOT pin-compatible - a board redesign is required to migrate between them.

Choose the PIC17C762-16E/PT when you need a high-I/O-count 8-bit MCU with extended -40 C to +125 C industrial temperature grade for automotive, outdoor industrial or HVAC systems. The OTP memory suits mature, fixed-firmware designs where unit cost dominates and field updates are not required. For flash-based designs or new product starts, Microchip recommends the PIC18F8520, which is NOT pin-compatible. For lower temperature grades, the PIC17C762-16I/PT (-40 C to +85 C) or PIC17C762-16/PT (0 C to +70 C) are direct pin-compatible drop-in alternatives. For mask-ROM production runs the PIC17C756A family offers the same 80-TQFP footprint but requires factory-programmed firmware.

주요 차별점
- Highest temperature grade in the PIC17C762 family (vs PIC17C762-16I/PT)
- OTP memory enables lower unit cost than flash equivalents at high volume (vs PIC18F8520)
- Higher I/O count than typical 8-bit PIC16 MCUs (vs PIC16F877A-I/PT (40-pin DIP))
설계 노트
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.
