PIC17LC762T-08I/PT Overview
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory (ROM/Flash/OTP), working memory (RAM), and programmable I/O peripherals. The PIC17 family is positioned within Microchip's 8-bit MCU hierarchy above PIC16 and below the enhanced 16-bit dsPIC/PIC24 families; it belongs to the broader class of RISC microcontrollers and, ultimately, embedded system semiconductors. MCUs are the central control element in nearly every embedded product, executing firmware that drives sensors, actuators, displays, and communication interfaces.
Key features include 58 single-word instructions, single-cycle execution (except for program branches and table reads/writes which take two cycles), a hardware multiply engine that completes in one instruction cycle, and dual 8-bit timer/counters with multiple capture/compare/PWM modes. The 10-bit A/D converter with multiple input channels provides on-chip analog signal acquisition, eliminating external ADC components in many designs.
From an architectural standpoint, the PIC17C core uses a 16-bit instruction word with an 8-bit data path, separated program and data buses (Harvard architecture), and a 16-level hardware stack. The OTP program memory variant ('C') is one-time programmable and is typically used in production where firmware is stable; for development, Microchip offers windowed (JW) and Flash (F) variants in the same family.
Typical applications include industrial control systems, motor control, sensor signal conditioning, instrumentation, and embedded control boards where deterministic single-cycle instruction execution simplifies real-time firmware design. The wide 2.5 V to 5 V supply range also supports both 3.3 V and 5 V system designs.
When designing with this part, verify that the OTP memory capacity (16 KB) is sufficient for production firmware; use the PIC17C762 Flash or emulator equivalent during development to avoid wasting OTP units. The 80-pin TQFP footprint should be checked against PCB thermal and routing budgets - the package's fine pitch requires careful layout for manufacturability.

Typical Applications
PIC17LC762T-08I/PT is suitable for 6 applications: Industrial Control Systems, Motor Control and Drivers, Instrumentation and Data Acquisition, Sensor Signal Conditioning Hubs, Embedded Control Boards with Human-Machine Interface, Automotive Body and Chassis Electronics (Non-Safety).
Industrial Control Systems
The PIC17LC762T-08I/PT suits industrial control boards that need deterministic single-cycle execution and on-chip analog acquisition. Its 8 MHz clock yields a 121 ns instruction cycle, which simplifies real-time PID loop timing without an RTOS. The 33 I/O pins drive relays, optocouplers, and digital sensors directly, while the 10-bit A/D reads 4-20 mA loop signals through a current-sense amplifier. The wide 2.5 V-5 V supply range lets the same board accept 24 V industrial bus rails stepped down to 5 V or 3.3 V. The 80-pin TQFP provides enough pin budget for parallel LCDs, keypads, and CAN/RS-485 transceivers. Compared with a soft-core MCU, the PIC17C's single-cycle hardware multiplier accelerates digital filter math for sensor linearization.
Recommended
Motor Control and Drivers
The PIC17LC762T-08I/PT's hardware CCP modules and timer/counters generate the PWM waveforms required for brushed DC, stepper, or BLDC motor control. Its 121 ns instruction cycle provides tight control-loop timing at 8 MHz, which keeps current sampling and commutation jitter low for smooth torque. The 10-bit A/D converter samples shunt-resistor feedback signals for closed-loop current control, while the hardware multiplier accelerates Park/Clarke transforms. The 33 I/O lines connect to gate drivers such as the IR2104 or to H-bridge enable inputs without muxing. Industrial temperature grade (-40C to +85C) handles under-hood and factory-floor thermal stress.
Recommended
Instrumentation and Data Acquisition
The PIC17LC762T-08I/PT's integrated 10-bit A/D converter with multi-channel input provides on-chip analog acquisition for instrumentation front-ends. The 58 single-word instruction set and single-cycle hardware multiplier accelerate DSP-like operations such as moving-average filters, RMS calculations, and linearization curves directly in firmware. The 16 KB OTP program memory holds calibration tables and sensor compensation coefficients. The 33 digital I/Os interface to LCD displays, keypads, and UART/RS-232 links for instrument panels. The 80-pin TQFP allows routing of analog and digital grounds separately, critical for low-noise measurement integrity.
Recommended
Sensor Signal Conditioning Hubs
Use the PIC17LC762T-08I/PT as a hub that aggregates multiple sensors, performs on-board linearization, and forwards results over UART, SPI, or I2C. The 10-bit A/D converter reads thermistor, strain-gauge, or photocell outputs with sufficient resolution for many embedded monitoring products. The hardware multiplier (8x8 in one cycle) accelerates polynomial compensation math that would otherwise burden a smaller MCU. The 33 I/O lines fan out to multiple SPI peripherals or an I2C sensor bus. With its 2.5 V to 5 V supply range, the same board can be powered from a single Li-ion cell or a 5 V regulated rail.
Recommended
Embedded Control Boards with Human-Machine Interface
The PIC17LC762T-08I/PT's 33 I/O pins comfortably drive character LCDs (4-bit mode), 4x4 keypads, status LEDs, and rotary encoders simultaneously without external muxing. Its 16 KB OTP holds menu state machines, multi-language string tables, and event logging firmware. The 80-pin TQFP leaves headroom for SPI-driven graphical LCDs or external EEPROM for parameter storage. The single-cycle 121 ns instruction execution keeps button-debounce and display-refresh loops responsive. Industrial temperature rating supports use in factory HMI panels, kiosks, and appliance front panels.
Recommended
Automotive Body and Chassis Electronics (Non-Safety)
The PIC17LC762T-08I/PT's industrial temperature grade (-40C to +85C) and robust CMOS process handle under-hood and cabin thermal environments for non-safety body controllers (lighting, mirror, seat modules, HVAC dampers). The 33 I/O lines drive relays, half-bridges, and LIN-bus transceivers for body networks. The 10-bit A/D reads battery voltage, temperature, and potentiometer positions. Although not AEC-Q100 qualified, its industrial rating covers many non-safety automotive applications. The 80-pin TQFP footprint supports through-hole or SMD assembly with conformal coating for vibration resistance.

Key Differentiators
- Single-cycle hardware multiplier for deterministic DSP-like math (vs PIC16F877A-I/PT)
- Wide 2.5 V to 5 V supply range (vs PIC17C762 (non-L variant))
- Industrial temperature grade with OTP program memory (vs PIC16F877A-I/PT (Flash))
Design Notes
The 'T' suffix in PIC17LC762T-08I/PT indicates tape-and-reel packaging, not a silicon or electrical variant - substituting the non-T tray version is functionally identical for the PCB. However, the 'L' in PIC17LC762 denotes the low-voltage (2.5 V to 5 V) supply variant; substituting a non-L PIC17C762 changes the supply range to 4.5 V to 5.5 V and may cause brownout-reset misbehavior at 3.3 V. Always verify both voltage suffix and packaging suffix when cross-referencing.
The 80-pin TQFP (PT) package has a 0.5 mm pitch and requires careful PCB land pattern design per IPC-7351. Place 0.1 uF ceramic decoupling capacitors as close as possible to each VDD/VSS pair, with a bulk 10 uF tantalum or ceramic near the IC. Separate analog and digital grounds with a single-point connection under the MCU to minimize A/D noise; route A/D reference voltage (VDD/VREF) with wide traces and bypass it locally. The TQFP exposed pad (if present) should be soldered to the ground plane for thermal dissipation.
At 8 MHz clock and 5 V supply, the PIC17LC762T-08I/PT typically dissipates under 100 mW during active execution. In sleep/standby modes, power drops to microamp levels per the PIC17C family datasheet. The TQFP-80 package's theta_JA is approximately 50 C/W, so junction rise above ambient at full activity is roughly 5 C - no heatsink is needed for typical embedded applications. Verify thermal margin in sealed enclosures without forced airflow.
