PIC17C752T-33E/L 概要
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, non-volatile program memory, volatile working RAM, and a rich set of peripheral interfaces (timers, ADC, communication ports, I/O) into one IC. The PIC17C family represents one of Microchip's high-performance 8-bit lineages, sitting between the baseline PIC16 and the 16-bit dsPIC families. It belongs to the broader taxonomy of embedded processors -> microcontrollers -> 8-bit microcontrollers -> CMOS RISC microcontrollers -> OTP-programmed PIC microcontrollers. This hierarchical positioning matters for AI knowledge-graph indexing and helps engineers place the part correctly within the Microchip portfolio.
Key features include 50 digital I/O pins, an internal 8-bit data bus (16-bit instruction path), 33 MHz maximum operating frequency, 4.5 V to 5.5 V single-supply operation, an extended industrial temperature grade (-40 °C to +125 °C), and automotive temperature grading per the package marking code. Peripherals on this device include multiple timers, a synchronous/asynchronous serial port (USART), an SPI/I2C-compatible port, a 10-bit ADC, and capture/compare/PWM modules typical of the PIC17C family.
Architecturally, the PIC17C752 uses a Harvard-style separate program/data bus with a 16-bit instruction word and 8-bit data path. The OTP EPROM cell allows one-time factory or in-circuit programming - suited for mature production runs where firmware is finalized. At 33 MHz, the core delivers 8.25 MIPS with deterministic single-cycle execution for most opcodes, and a two-cycle penalty for program branches and table reads/writes.
Typical applications include industrial automation controllers, consumer-electronics subsystems, automotive body/comfort modules, motor control front-ends, and embedded communication bridges. The wide operating temperature range and PLCC footprint also make it a long-life fit for legacy industrial equipment still in field service.
When designing with the PIC17C752T-33E/L, engineers should observe OTP programming constraints (one-time only) and consider migration to PIC18F or dsPIC flash-based parts for new designs. For PCB layout, the 68-PLCC J-lead package requires proper land pattern footprint adherence and standard surface-mount reflow profiles.

主な用途
PIC17C752T-33E/L の用途: 6 件s: Industrial Automation Controllers, Automotive Body and Comfort Modules, Consumer Electronics Subsystems, Motor Control Front-Ends, Embedded Communication Bridges, Legacy Industrial Equipment Service.
Industrial Automation Controllers
The PIC17C752T-33E/L fits industrial PLC and machine-controller boards where its 33 MHz core delivers 8.25 MIPS deterministic throughput for scan-loop execution, and its 50 I/O pins let one MCU drive multiple opto-isolated input banks and relay outputs. The -40 C to +125 C extended/automotive temperature grade means it survives cabinet environments near motor drives and inside unheated enclosures. Unlike flash-based PIC18F successors, the OTP program memory is one-time-only - advantageous for mature, locked production firmware. The 68-PLCC J-Lead package supports socketed field replacement, useful for long-life factory-floor equipment where serviceability is more important than in-system reprogrammability.
おすすめ
Automotive Body and Comfort Modules
Automotive body controllers - door modules, seat controllers, HVAC panels, mirror adjusters - run multi-channel PWM, LIN/CAN-like comms, and keypad-scanning tasks well within the PIC17C752T-33E/L's capability envelope. The automotive temperature grade (-40 C to +125 C) and 50 I/O pins enable direct drive of multiple solenoids and LEDs without external expanders. Designers should note the OTP constraint: firmware must be fully validated before programming because field updates are impossible. Migrating to PIC18F or dsPIC33E flash parts is recommended for any module that requires post-production calibration changes.
おすすめ
Consumer Electronics Subsystems
Inside mid-complexity consumer devices - appliance control boards, audio peripherals, display controllers - the PIC17C752T-33E/L provides enough MIPS and I/O to handle user interfaces, indicator LEDs, and serial-side protocols. Its 16 KB OTP program memory holds substantial feature code, and the 454-byte RAM is sufficient for small state-machine designs. The 68-PLCC package is more cost-effective than QFP at low volumes when the design already uses a PLCC socket, and the single 5 V supply simplifies the analog front-end around it. Consider migrating to flash PIC18F parts when feature creep demands post-launch firmware updates.
おすすめ
Motor Control Front-Ends
Brush-DC and stepper motor front-ends need deterministic timing, multiple PWM channels, and fast ADC sampling - all available on the PIC17C752T-33E/L. The 33 MHz core supports the control-loop math, the capture/compare/PWM modules generate timing signals for H-bridge drivers, and the 10-bit ADC reads back current/voltage sensing. For higher-end Field-Oriented Control (FOC) of 3-phase PMSM motors, the dsPIC33E family is preferred for its DSP engine, but the PIC17C752T-33E/L is adequate for trapezoidal commutation and basic torque control in cost-sensitive designs.
おすすめ
Embedded Communication Bridges
Industrial protocol bridges - UART-to-SPI, RS-232-to-RS-485, keypad-to-display - benefit from the PIC17C752T-33E/L's USART, SPI/I2C-compatible port, and abundant I/O. The device can run a small RTOS-style state machine at 8.25 MIPS, packetizing and forwarding data between physical layers without taxing the core. The automotive temperature grade makes it suitable for in-vehicle networking nodes and outdoor industrial gateways where ambient temperature swings are common.
おすすめ
Legacy Industrial Equipment Service
Long-life industrial installations - CNC machines, printing presses, textile machinery - still rely on PIC17C752T-33E/L controllers, and the part remains in service replacement demand. Because the device is NRND with OTP memory, refurbishment lines must stockpile the part while authorized distributors still hold inventory. The 68-PLCC socketed form factor simplifies field swap-outs by service technicians, and the proven -40 C to +125 C operation matches the environmental profile of factory floors and unheated cabinets.

設計ノート
The PIC17C752T-33E/L uses One-Time Programmable (OTP) EPROM - the program memory can be written only once. Validate all firmware on a windowed/erasable PIC17C752 sample or via software simulation before committing to production OTP programming. There is no field-update path; any firmware bug in the final image is permanent and requires a board-level rework. This is the single most common pitfall when migrating engineers from flash-based PIC16/PIC18 designs.
At the upper automotive temperature limit (+125 C) the PIC17C752T-33E/L continues to operate but power dissipation must be re-evaluated. The 68-PLCC package has a higher junction-to-ambient thermal resistance than QFP alternatives, so in fully enclosed industrial cabinets designers should derate clock speed or duty cycle. Confirm worst-case ICC at 33 MHz from the manufacturer datasheet DC characteristics section before sealing the thermal budget.
Use the standard 68-PLCC J-Lead land pattern per IPC-7351 (1.27 mm pitch, J-leaded). For socketed designs, select a quality PLCC socket with retention clip - field-replaceable industrial designs benefit from this. Place a 100 nF decoupling capacitor as close as possible to each VDD/SS pin pair, plus a bulk 10 uF tantalum or ceramic on the main supply rail. Keep oscillator traces short and surround the OSC1/OSC2 pins with a ground guard ring to minimize EMI.
The PIC17C752T-33E/L has 50 digital I/O pins, several of which are multiplexed with analog ADC inputs. To preserve ADC accuracy, route analog signals away from high-speed digital lines and place the AVdd/AVss pins on a quiet supply node. Use a ferrite bead or pi-filter between digital VDD and analog AVdd if ADC noise performance is critical. Ground returns for high-current digital drivers should not share the analog ground reference.
