PIC17C762-33E/PT Présentation
A microcontroller (MCU) is a single-chip computer containing a CPU core, program memory, data RAM, and configurable peripherals. The PIC17C family occupies a high-end position in Microchip's classic 8-bit PICmicro® hierarchy, sitting between the PIC16 mid-range family and the PIC18 enhanced family. RISC (Reduced Instruction Set Computer) architecture means the 17C762 executes most instructions in a single instruction cycle, and the OTP program memory lets manufacturers program each unit once at production time, which is typical for volume automotive and industrial control modules.
Key differentiating features include the 58 single-word instruction set (with only program branches and table reads/writes being two-cycle), 50 bidirectional I/O ports, an internal 10-bit A/D converter, multiple timer/counter modules, and a 16-bit internal data path that enables fast arithmetic. The TQFP-80 package provides ample pin count for parallel buses, external memory expansion, and abundant analog/digital mixed-signal interfacing in a slim 12 mm x 12 mm outline suitable for space-constrained PCB layouts.
Typical applications include automotive body and chassis controllers, industrial automation modules, embedded control boards that require moderate program memory with deterministic interrupt latency, and legacy designs transitioning from older 8-bit PIC architectures. Designers working on new projects should evaluate the PIC18F8520, which Microchip designates as the recommended migration path for the PIC17C762. When designing with this MCU, allocate the program EPROM budget at 16 KB maximum, ensure oscillator stability with proper crystal loading capacitors, and use the In-Circuit Serial Programming (ICSP) interface for production programming since the OTP memory cannot be reprogrammed in the field.

Applications typiques
PIC17C762-33E/PT convient pour 6 applications: Automotive Body and Chassis Controllers, Industrial Automation Controllers, HVAC and Climate Control Modules, Appliance Control Boards, Point-of-Sale Terminal Peripherals, Legacy 8-bit PIC Design Maintenance.
Automotive Body and Chassis Controllers
The PIC17C762-33E/PT is well-suited to automotive body and chassis electronic control units because it combines the Extended -40 °C to +125 °C automotive temperature grade with 50 digital I/O lines for switch and relay interfaces, plus a 10-bit A/D converter for analog sensor conditioning. Its 8.25 MIPS throughput at 33 MHz is sufficient for real-time CAN-style body networking, lighting control, seat modules, and HVAC damper actuation. The OTP EPROM programming model is well matched to high-volume production where each variant is programmed once and never reprogrammed in the field.
Recommandé
Industrial Automation Controllers
In industrial PLC and machine-controller subsystems, the PIC17C762-33E/PT provides deterministic 121 ns single-cycle instruction execution that simplifies real-time control loop timing. Its 16 KB OTP program memory accommodates mid-sized ladder-logic-style control sequences, while 50 GPIO pins can directly drive optocouplers, relay coils, and indicator LEDs. The Extended -40 °C to +125 °C temperature grade supports cabinet-internal or outdoor-mounted installations subject to wide thermal swings, and the 4.5 V to 5.5 V supply range tolerates noisy 5 V industrial rails.
Recommandé
HVAC and Climate Control Modules
Climate-control appliances such as rooftop HVAC units, refrigerated transport controllers, and smart thermostats benefit from the PIC17C762-33E/PT's 10-bit A/D converter for reading thermistor and pressure sensors, combined with its 50 GPIO pins for driving triacs, fan motors, and valve solenoids. The 33 MHz core is more than adequate for PID control loops that run at sub-millisecond update rates. The Extended automotive temperature grade ensures reliable operation in attics, equipment closets, and engine compartments where ambient temperatures can exceed 70 °C.
Recommandé
Appliance Control Boards
White-goods appliance controllers - washing machines, dishwashers, and microwave ovens - require exactly the feature set that the PIC17C762-33E/PT provides: 50 GPIO pins for motor drivers and user-interface keypads, 10-bit A/D for sensing water level and temperature, and 8.25 MIPS throughput to manage multi-state cycle programs. The OTP EPROM model is ideal for one-time factory programming of model-specific firmware variants. The Extended temperature rating covers the heat-rise inside an appliance cabinet during full-power operation.
Recommandé
Point-of-Sale Terminal Peripherals
Point-of-sale peripherals such as receipt printer controllers, barcode scanner interfaces, and customer display drivers can use the PIC17C762-33E/PT for its combination of high GPIO count and deterministic interrupt response. The 16 KB program memory accommodates USB-HID or RS-232 stack implementations, and the 33 MHz execution rate supports real-time serial protocol handling. The Extended temperature grade suits retail environments with limited climate control, and the OTP EPROM allows per-customer firmware personalization at the production line.
Recommandé
Legacy 8-bit PIC Design Maintenance
The PIC17C762-33E/PT is also widely used in long-lifecycle industrial, military, and medical equipment programs that were originally designed around the PIC17C family and require ongoing service-part production. Because the OTP EPROM is non-volatile and the pinout is stable across PIC17C762 variants, field-replacement boards can be programmed with verified legacy firmware. Designers supporting these installed bases should note the NRND status and plan transitions to the PIC18F8520 over the next design refresh cycle.

Notes de conception
Decouple VDD pins (11, 40, 60, 80) with a 100 nF ceramic capacitor placed as close as possible to each VDD pin, plus a single 10 uF bulk capacitor on each VDD/VSS pair. The PIC17C762 has four VDD pins to support the high-current transients of the internal EPROM programming charge pump; under-driving any single VDD pin can cause code-fetch errors during write cycles. Place the bulk capacitor with the shortest possible trace to the VSS plane.
The PIC17C762-33E/PT uses OTP EPROM that can be programmed only once. There is no field-erase capability, so production programmers must fully verify firmware before ICSP programming. Build a production programming flow that includes: (1) signature verification, (2) blank-check, (3) program, (4) verify, and (5) bulk-erase prevention. Reserve unused code space with a GOTO $ trap so that any unexpected jump yields a recoverable reset rather than silent data execution.
Route the 33 MHz oscillator traces (OSC1/OSC2 pins 1-2) with short, symmetric traces to the crystal or ceramic resonator, and surround them with a grounded guard ring to prevent coupling into adjacent analog inputs. Keep the crystal within 5 mm of the OSC pins to minimize parasitic capacitance. For EMI-sensitive applications, place a small ferrite bead on the MCLR reset line (pin 3) and a 10 kohm pull-up to VDD to ensure clean reset behavior during supply transients.
Estimated: At maximum 33 MHz clock with all peripherals active, the TQFP-80 package dissipates approximately 0.4 W under typical 5 V operation, with a theta_JA of approximately 50 C/W on a 4-layer JEDEC test board. This yields a junction temperature rise of 20 C above ambient, which is well within the 125 C automotive limit. For designs in sealed enclosures without forced airflow, validate with thermocouple measurements during worst-case thermal soak testing.
Informations de conformité
RoHS, REACH, AEC-Q100, lead-free, and halogen-free status were not present in the verified web data for PIC17C762-33E/PT. The Extended (-40C to +125C) temperature grade suffix 'E' supports automotive use cases but does not by itself confirm AEC-Q100 qualification. The PIC17C762 family uses OTP EPROM and is supplied in Tray packaging.
