PIC17C762T-33I/L Visão geral
An 8-bit microcontroller (MCU) is a single-chip computer that combines a CPU, program memory, data RAM, and peripherals on one die. Within the PIC taxonomy, the PIC17C family sits in the high-performance tier between the mid-range PIC16C/PIC16F devices and the enhanced PIC18F family, offering a 16-bit-wide instruction word, an 8-bit hardware multiplier, and an instruction cycle as short as 121 ns at the maximum 33 MHz oscillator rate. These characteristics place PIC17C parts in the hierarchy: microcontroller -> embedded MCU -> 8-bit MCU -> PIC family -> PIC17C sub-family -> CMOS EPROM/OTP variants.
Key features of the PIC17C762T-33I/L include a single-cycle 121 ns instruction execution (except for program branches and table reads/writes which are two-cycle), an 8-bit single-cycle hardware multiplier, 50 I/O ports, and a wide operating voltage of 4.5 V to 5.5 V. The 'T' suffix in the part number indicates tape-and-reel packaging, the '33' indicates a 33 MHz maximum clock input, the 'I' indicates an industrial temperature grade of -40 C to +85 C, and '/L' indicates the 84-pin PLCC package. The 'C' between PIC17 and 762 indicates the EPROM/OTP program-memory variant, distinguishing it from later ROMless (PIC17C76x) and flash (PIC17C7xx) revisions.
The PIC17C762T-33I/L's RISC-style Harvard architecture isolates the program-memory bus from the data-memory bus, allowing instruction fetch and operand access to occur on the same cycle. The integrated 10-bit ADC with multiple input channels removes the need for an external converter in many sensor-interface designs, while the high pin count (66 I/O per the Mouser listing, 50 per other sources - see _validation_note) supports complex human-machine interface or parallel-bus applications. The OTP memory variant suits prototyping and pre-production builds where one-time programming is acceptable and the larger flash-based PIC18F family is not yet qualified.
Typical applications for the PIC17C762T-33I/L include industrial control systems, motor drive front-ends, automotive body and chassis ECUs, data-acquisition front-ends, and consumer-electronics controllers. The combination of 50+ I/O lines, 10-bit ADC, and 121 ns instruction throughput makes the device attractive for legacy 8-bit designs that need deterministic timing without migrating to a 16-bit dsPIC.
When designing with this device, note that the PIC17C family is in NRND/EOL status at Microchip and should be considered a long-term-availability part rather than a new-design choice. For new designs, Microchip recommends the PIC18F family or dsPIC33 family as functional replacements that share development-tool chains (MPLAB X IDE, MPLAB ICD programmers) but require PCB respin due to differing pinout and peripheral sets.

Aplicações típicas
PIC17C762T-33I/L é adequado para 6 aplicaçãos: Industrial Control Systems, Motor Drive Front-End, Automotive Body and Chassis ECUs, Data-Acquisition Front-Ends, Consumer Electronics Controllers, Legacy Test and Measurement Equipment.
Industrial Control Systems
The PIC17C762T-33I/L fits industrial control applications because its 50+ digital I/O lines, 16-channel 10-bit ADC, and 121 ns deterministic instruction cycle support sensor acquisition, actuator drive, and PID control in a single chip. Placed on a control board with 5 V supply, it scans digital inputs, runs an ADC scan on analog channels, computes a PID loop, and drives triac/SSR outputs within a single 121 ns cycle. The 33 MHz throughput beats PIC16F alternatives for tight control loops, though the NRND status means new designs should plan a migration path to PIC18F or dsPIC33.
Recomendado
Motor Drive Front-End
The PIC17C762T-33I/L serves as a motor drive front-end controller because its 121 ns instruction cycle and 8-bit hardware multiplier handle field-oriented control (FOC) and trapezoidal commutation algorithms at high PWM frequencies. Connected to a three-phase inverter gate driver and current-sensing shunts, the MCU runs ADC-triggered PWM loops with deterministic timing. The OTP memory requires code masking for production, but allows fast prototyping without the erase delays of flash. Engineers designing new motor drives should consider dsPIC33EP parts with dedicated motor-control PWMs.
Recomendado
Automotive Body and Chassis ECUs
The PIC17C762T-33I/L has historically been deployed in automotive body controllers and chassis ECUs because its industrial temperature rating and 5 V I/O tolerance match legacy 12 V automotive bus interfaces (with external transients). The 50+ I/O lines support multiple switch/sensor inputs and lamp/relay outputs, while the 10-bit ADC reads battery voltage and sensor signals. Modern designs should use AEC-Q100-qualified PIC18F or dsPIC33 parts; the PIC17C762T-33I/L is acceptable only for maintaining legacy automotive electronics already in service.
Recomendado
Data-Acquisition Front-Ends
The PIC17C762T-33I/L functions as a data-acquisition front-end because its 10-bit ADC with up to 16 input channels multiplexes many analog sensors onto a single converter with 121 ns throughput. Used between analog signal-conditioning stages and an upstream serial link, the MCU sequences ADC reads, applies digital filtering, and pushes results over UART/SPI. The 678-byte RAM buffers acquisition bursts, while the 16 KB OTP stores calibration tables. For higher ADC resolution (12-16 bits), consider PIC18F or dsPIC33 families with enhanced ADC peripherals.
Recomendado
Consumer Electronics Controllers
The PIC17C762T-33I/L controls consumer appliances and white goods because its 5 V tolerant digital I/O, 50-pin count, and 10-bit ADC handle user-interface buttons, displays, and sensor feedback at low BOM cost. Placed in washing-machine, dishwasher, or HVAC controls, the MCU sequences motor/valve outputs while reading temperature, water level, and pressure sensors through the ADC. The OTP memory locks the firmware at production. New designs should consider PIC18F46K22 or PIC18F67K22 for drop-in compatible flash memory and pinout migrations.
Recomendado
Legacy Test and Measurement Equipment
The PIC17C762T-33I/L is widely deployed in legacy test-and-measurement instruments and laboratory equipment where deterministic 121 ns instruction timing and abundant I/O support parallel-bus displays, keypads, and measurement front-ends. Used in bench multimeters, signal generators, and process calibrators, the MCU drives LCD/VFD displays and reads reference voltages through the 10-bit ADC. The NRND status means new T&M designs should adopt PIC18F or dsPIC33, but maintaining existing equipment is fully supported by Microchip through end-of-life contracts.

Principais diferenciais

- Industrial temperature range standard (vs PIC17C762T-33/L (commercial temp))
- 121 ns single-cycle instruction execution (vs PIC17C756AT-33I/L (sibling family))
Notas de projeto
Estimated: at maximum 33 MHz clock with all 50 I/O lines toggling at full CMOS drive (20 mA per pin), peak power dissipation reaches approximately 1 W on the PLCC package. The 84-PLCC has theta_JA of roughly 35 C/W in still air, yielding a 35 C junction temperature rise above ambient. For -40 C to +85 C industrial operation, ensure the board layout provides at least 1 square inch of continuous copper plane beneath the PLCC pad to spread heat; airflow or heatsinking is not required at typical 8-20% duty I/O loads.
Place the 5 V supply bypass capacitor (0.1 uF ceramic in parallel with 10 uF tantalum) within 5 mm of the VDD pin to suppress switching noise from the internal oscillator driver. Keep crystal traces short and surrounded by a ground guard ring; the PIC17C762's high-gain oscillator is sensitive to stray capacitance. Use a 4-layer PCB with dedicated VDD/VSS planes for production builds; 2-layer designs are acceptable for prototypes if ground returns are wide and uninterrupted under the device.
Do not exceed the absolute maximum VDD of 7.0 V; the OTP memory programming algorithm requires 12-14 V on the MCLR pin during code-mask programming, which can damage nearby analog inputs if the analog supply is not properly isolated. The 'C' (CMOS EPROM) variant requires special UV-erase-compatible windowed packages for development; production OTP parts cannot be re-programmed. Engineers migrating to flash parts must plan for code-mask tool changes and cannot use a PIC17C762T programmer on a PIC18F or dsPIC33 device.
Informações de conformidade
RoHS status not explicitly stated in verified web data; PIC17C762T-33I/L is an NRND legacy product. AEC-Q100 not qualified - automotive designs should use AEC-Q100-qualified PIC18F or dsPIC33 parts.
