An 8-bit microcontroller (MCU) is a single-chip computer that integrates a CPU, non-volatile program memory (ROM/EPROM/Flash/OTP), volatile data memory (RAM), and programmable I/O peripherals on one die. The PIC17C family sits at the high end of Microchip's classic 8-bit lineup, above the PIC16C and PIC12C series, and is source-compatible with the PIC16C5X, PIC12CXXX, and PIC16CXX devices. Within the broader taxonomy, the PIC17C is a Harvard-architecture RISC controller with an 8-bit data path, classified as a microcontroller -> embedded processor -> semiconductor IC.
Key features of the PIC17C752-16E/PT include: four additional timers versus the PIC16C baseline, four capture inputs, three PWM outputs, a 12-channel 10-bit analog-to-digital (A/D) converter, external memory addressing, and a synchronous serial port configurable as either 3-wire SPI or 2-wire I2C. Two USART channels provide asynchronous and synchronous serial communication, and the part supports up to 50 I/O pins from its 64-pin TQFP package. The 'E' suffix indicates the extended industrial temperature grade of -40C to +125C, while the 'PT' suffix denotes the plastic TQFP package.
Architecturally, the PIC17C752 uses a 16-bit instruction word with an 8-bit data path. The Harvard bus separates program and data fetches so most instructions complete in one cycle. The 10-bit A/D converter, PWM modules, capture inputs, and USARTs are mapped to dedicated SFRs; developers access peripherals through banked register selects. External memory addressing extends program space beyond on-chip OTP for applications needing larger code.
Typical applications include industrial control, automotive body and chassis modules, instrumentation with analog front ends, motor control with PWM, and embedded control requiring SPI/I2C peripheral expansion. The 12-channel 10-bit ADC suits multi-sensor monitoring, while the PWM and capture peripherals support closed-loop motor control. The part's automotive temperature rating and OTP-based supply model also fit pre-production and low-volume automotive programs.
When designing with the PIC17C752-16E/PT, note that the 'E' (extended -40C to +125C) grade makes it the right choice for automotive or harsh-environment products, whereas the standard PIC17C752-16/PT (0C to +70C commercial) fits office and lab equipment. OTP memory requires programming at the factory or via a device programmer before solder reflow; plan the firmware supply chain accordingly. A newer pin-compatible Flash alternative, PIC18F6520, is recommended for new designs.

典型應用
PIC17C752-16E/PT 適用於 6 應用s: Industrial Process Control, Automotive Body and Chassis Modules, Motor Control and PWM Drive, Instrumentation and Data Acquisition, Embedded SPI/I2C Peripheral Hub, Harsh-Environment Sensor Interface.
Industrial Process Control
The PIC17C752-16E/PT suits industrial process control with its 12-channel 10-bit ADC for multi-sensor monitoring, three PWM outputs for actuator drive, and extended -40C to +125C temperature grade for harsh environments. Placed on a control board, the MCU reads 4-20 mA or 0-10V sensor signals via the ADC, drives PWM-controlled valves or heaters, and communicates over RS-485 via USART. The 16KB OTP holds small to medium control algorithms; unlike Flash MCUs, OTP locks firmware at production.
推薦
Automotive Body and Chassis Modules
The PIC17C752-16E/PT's -40C to +125C extended temperature grade qualifies it for automotive body control modules such as lighting controllers, seat controllers, and HVAC flaps. The 50 I/O pins connect to switches, relays, and LEDs; the PWM outputs drive motors for mirror or seat adjustment; and the SPI/I2C port talks to sensor ASICs. Note the part is NRND - new automotive designs should target PIC18F6520 with Flash and CAN. Existing production runs can continue using PIC17C752-16E/PT.
推薦
Motor Control and PWM Drive
The PIC17C752-16E/PT provides three PWM outputs and four capture inputs, supporting closed-loop DC motor, BLDC, or stepper control in industrial drives and small appliances. The capture inputs measure encoder feedback or tachometer pulses; the PWM outputs drive MOSFET gate drivers via level shifters. The 16MHz core runs field-oriented control or trapezoidal commutation at moderate RPM. With 16KB OTP, control firmware is locked at production - a benefit for anti-tamper industrial designs.
推薦
Instrumentation and Data Acquisition
The PIC17C752-16E/PT's 12-channel 10-bit ADC, SPI/I2C, and USART peripherals suit multi-channel data loggers, bench instruments, and portable measurement devices. The ADC scans sensors at up to ~50 ksps aggregate; the USART streams data to a host PC or display; the SPI/I2C connects to external ADC, DAC, or EEPROM. The 454-byte RAM supports small buffer rings; the 16KB OTP holds compression and protocol stacks. Designers needing more memory can move to PIC17C756-16E/PT with 32KB.
推薦
Embedded SPI/I2C Peripheral Hub
The PIC17C752-16E/PT acts as a peripheral hub, aggregating SPI sensors, I2C devices, and UART modules behind a single MCU that bridges to a host controller. The configurable synchronous serial port handles either 3-wire SPI or 2-wire I2C master/slave, and the two USARTs add RS-232/RS-485 channels. The 50 I/O lines drive status LEDs and read configuration DIP switches. Extended temperature allows deployment in industrial enclosures. Use PIC17C752-16E/PT to consolidate discrete logic into one programmable hub.
推薦
Harsh-Environment Sensor Interface
The PIC17C752-16E/PT's -40C to +125C operating range, 50 I/O pins, and 12-channel 10-bit ADC make it a sensor-interface MCU for outdoor, under-hood, or industrial-oven installations. Connect thermocouples via op-amp front ends to the ADC channels, read digital sensors over SPI/I2C, and stream data via USART. The OTP program memory prevents field firmware tampering - a security plus. For new designs needing firmware updates, Microchip recommends migrating to PIC18F6520 with Flash and EEPROM emulation.

主要差異化特點
- Extended -40C to +125C temperature grade (對比PIC17C752-16/PT)
- Recommended replacement available on same footprint (對比PIC17C752-16E/PT (this part))
- Larger 32KB OTP option in same package (對比PIC17C756-16E/PT)
設計說明
OTP (One-Time Programmable) memory cannot be erased or rewritten. Confirm firmware is fully debugged and validated before programming the PIC17C752-16E/PT. A single bit error requires scrapping the part. For new designs or firmware iteration, Microchip recommends PIC18F6520 with Flash.
Place decoupling capacitors (100 nF ceramic plus 10 uF tantalum/bulk) within 5 mm of each VDD/VSS pair on the PIC17C752-16E/PT. Use a ground plane under the TQFP package and keep crystal traces short to minimize EMI. The 64-TQFP exposed-pad-less design requires careful thermal management at high MIPS loads.
The PIC17C752-16E/PT operates from 4.5V to 5.5V; voltages below 4.5V risk brown-out. Add a 100 nF bypass cap on each VDD pin and a 10 uF bulk cap at the regulator output. Use an LDO or switching regulator with <50 mVpp ripple at the MCU supply pins to prevent ADC inaccuracies during sampling.
合規資訊
RoHS compliance per Microchip product page. The 'E' temperature grade is qualified for automotive underhood environments but AEC-Q100 formal qualification status is not separately documented for this OTP part.
