PIC17C762-33E/L - 8-bit 33MHz MCU, 16KB OTP, 84-PLCC | Microchip
MPN: PIC17C762-33E/L ✓ AktifPIC17C762-33E/L Ringkasan
A microcontroller (MCU) is a single-chip computer containing a processor core, program memory, data memory, and programmable I/O peripherals. The PIC® 17C family sits above the PIC16 family in Microchip's 8-bit hierarchy, offering expanded memory, higher throughput, and integrated analog peripherals aimed at complex embedded-control applications. Within the broader taxonomy, PIC17C762 belongs to: microcontroller → embedded controller → integrated circuit → semiconductor. Its Harvard architecture separates program and data buses, and its 58 single-word instruction set enables compact code generation while retaining deterministic timing.
Key features that differentiate this part include its 16-channel 10-bit ADC (sufficient for sensor-array multiplexing), 33 MHz operation yielding 8.25 MIPS throughput, 50 programmable I/O lines, and an OTP program memory that allows factory or prototype programming without requiring in-system re-programmability. The 84-PLCC J-Lead package provides a socket-compatible footprint well suited to industrial control boards and legacy automotive subsystems.
Typical applications include industrial automation controllers, automotive body and chassis modules, consumer-electronics motor control, and embedded instrumentation. The device is documented by the manufacturer as a mature OTP part with a recommended successor being the PIC18F8520, indicating that engineers designing new products should evaluate the flash-based PIC18 family. For maintenance of existing designs the PIC17C762-33E/L remains a recognized long-life-cycle component with verified distributor stock as of 2026-09-26.
When designing with the PIC17C762-33E/L, ensure the supply rail stays within 4.5 V to 5.5 V and that decoupling capacitors are placed within 5 mm of each power pin. Because OTP memory cannot be rewritten, plan for prototype validation in a windowed (JW) or emulator variant before committing to OTP parts for production.

Aplikasi Umum
PIC17C762-33E/L cocok untuk 6 aplikasis: Industrial Automation Controllers, Automotive Body and Chassis Modules, Consumer Electronics Motor Control, Embedded Instrumentation and Data Loggers, Point-of-Sale Terminals and Peripherals, Legacy Medical Device Controllers.
Industrial Automation Controllers
The PIC17C762-33E/L fits industrial automation controllers because its 50 programmable I/O lines drive multi-axis stepper/servo interfaces, while the 16-channel 10-bit ADC multiplexes analog sensor inputs (temperature, pressure, flow). At 33 MHz / 8.25 MIPS the MCU executes PID loops for closed-loop motion control within sub-millisecond cycle times. The 84-PLCC J-Lead package survives socketed factory-floor enclosures with vibration, and the -40 °C to +125 °C extended temperature grade tolerates unheated cabinet mounting. Designers pair the PIC17C762-33E/L with external CAN transceivers (e.g., MCP2551) or RS-485 drivers for plant-network connectivity.

Automotive Body and Chassis Modules
The PIC17C762-33E/L suits automotive body and chassis electronic modules where its -40 °C to +125 °C extended temperature grade handles under-dash thermal stress and its 50 I/O lines switch lamps, relays, and H-bridge motor drivers. The 16-channel 10-bit ADC reads throttle position sensors, brake-pressure transducers, and battery-voltage dividers with adequate resolution for body-controller applications. Note: the part is not AEC-Q100 qualified, so OEMs use it only in non-safety-critical body ECUs. The 84-PLCC J-Lead package fits legacy automotive PCB designs, and the OTP memory locks the calibration against field tampering.

Consumer Electronics Motor Control
The PIC17C762-33E/L drives consumer-electronics motor-control subsystems such as washing-machine drum controllers, dishwasher pumps, and HVAC damper actuators. Its 33 MHz core computes brushless-DC commutation tables and trapezoidal speed profiles in real time, while the 16-channel ADC samples back-EMF and current-sense amplifiers for sensorless control. The 678-byte RAM accommodates state-machine buffers for fault detection, and the 50 I/O lines drive gate-driver ICs (e.g., IR2104) for three-phase inverters. The 84-PLCC socketed form factor simplifies field service and warranty replacement.

Embedded Instrumentation and Data Loggers
The PIC17C762-33E/L serves embedded instrumentation such as multi-channel data loggers, environmental recorders, and process-control RTUs. Its 16-channel 10-bit ADC scans thermocouples, RTDs, and 4-20 mA loop inputs with sufficient density to eliminate an external analog mux in many designs. The 16 KB OTP program memory holds calibration tables and Modbus firmware, while 678 bytes of RAM buffer sample arrays before serial transmission. The 50 I/O lines drive LCD displays, keypads, and isolated UART channels, and the -40 °C to +125 °C range supports outdoor cabinet installation.

Point-of-Sale Terminals and Peripherals
The PIC17C762-33E/L fits point-of-sale (POS) terminal peripherals such as receipt printers, barcode scanners, and magnetic-stripe readers. Its 50 I/O lines drive stepper motors for paper feed, opto-interrupter sensors for paper-out detection, and UART channels for cash-drawer kickouts. The 33 MHz throughput executes DES/3DES encryption for PIN pads within acceptable latency budgets, and the 16 KB OTP secures the firmware image against end-user extraction. The 84-PLCC J-Lead package withstands the thermal cycling of POS enclosures placed near kitchen or window heating sources.

Legacy Medical Device Controllers
The PIC17C762-33E/L maintains long-life medical device controllers (infusion-pump displays, laboratory centrifuges, sterilizer controls) where the installed base still requires 5 V 8-bit MCU support. Its 16-channel 10-bit ADC reads pressure transducers, flow sensors, and conductivity probes; the 50 I/O lines drive LCDs, keypads, and alarm buzzers; and the 33 MHz MIPS handles supervisory loop closures for closed-loop drug-delivery or speed-control algorithms. Because the OTP memory locks validated firmware, FDA pre-market submissions retain their original code-image integrity without revision risk.

Diferensiator Kunci
- Extended industrial temperature range on the original part (vsPIC17C762-33I/L)
- Identical silicon with field-friendly tape-and-reel packaging (vsPIC17C762T-33E/L)
- Doubled program memory in the same footprint (vsPIC17C756AT-33E/L)
Catatan Desain
The PIC17C762-33E/L requires a regulated 4.5 V to 5.5 V supply; place a 100 nF decoupling capacitor within 5 mm of each VDD pin (pins 11, 21, 31, 41, 51, 61, 68) and a bulk 10 µF tantalum capacitor at the board entry point. The 84-PLCC has seven VDD pins distributed around the package, and inadequate decoupling is the most common cause of ADC accuracy degradation. Estimated: at 33 MHz the core draws roughly 25 mA typical; a switching regulator with 20 mV ripple can shift ADC LSBs by 1-2 counts.
Because PIC17C762-33E/L uses One-Time Programmable memory, any code bug discovered after programming bricks the part - there is no in-system flash recovery. Always validate firmware on a PIC17C762-33E/CL (windowed CERDIP) or PIC17C44-33/JW emulator first. OTP also means no field firmware updates: for products requiring post-deployment patches, Microchip recommends the flash-based PIC18F8520 successor instead.
The 84-PLCC J-Lead package has a theta_JA of approximately 45 °C/W when socketed and 35 °C/W when soldered to a 4-layer PCB with a continuous ground plane. Estimated: at full I/O load (50 outputs sourcing 20 mA each = 1 A) the part dissipates roughly 1.25 W internally, yielding a 44 °C rise above ambient on a 4-layer board. Industrial cabinets at +85 °C ambient therefore demand either reduced I/O drive or external cooling - verify with a thermocouple on the package top during worst-case validation.
Informasi Konformitas
RoHS, REACH, and lead-free status not stated in the verified web data; AEC-Q100 not qualified (PIC17C762 is a legacy industrial MCU without automotive qualification - Microchip recommends PIC18F8520 for new automotive designs).
