PIC17C752T-16I/L 개요
A microcontroller is a single-chip computer that integrates a CPU core, program memory, working RAM, and peripheral interfaces into one package. The PIC17C family sits at the high end of Microchip's 8-bit portfolio, sharing the PIC architecture hierarchy: PIC17C -> 8-bit MCU -> RISC microcontroller -> embedded controller. Its 16-bit instruction word (despite an 8-bit data bus) and 58-instruction RISC core give it 8.25 MIPS throughput - roughly five times the throughput of mid-range PIC16 devices - while keeping code development simple with only 58 single-word instructions to learn.
Key features that differentiate this part include 50 I/O pins, integrated 10-bit A/D conversion, hardware multiply in a single cycle, and an industrial operating temperature range of -40C to +85C. The OTP program memory supports one-time field programming, making the device well-suited to mature production designs. The PLCC-68 J-lead package is socket-compatible and easy to prototype with, supporting both surface-mount and through-hole assembly with a socket.
On the architecture side, the PIC17C752 uses a Harvard memory structure with separate program and data buses, allowing instruction fetch and operand read to occur in parallel. The single-cycle hardware multiplier accelerates DSP-style inner loops without software overhead, and the integrated 10-bit A/D removes the need for an external ADC in many sensor-interface designs. The 50 I/O pins are organized into ports that share pins with peripheral functions, allowing flexible multiplexing.
Typical applications include industrial control and instrumentation, motor control front-ends, sensor signal acquisition, embedded data logging, and consumer appliance controllers. Its OTP memory and PLCC socket-friendly package make it a natural fit for medium-volume production where field reprogrammability is not required.
When designing with this device, ensure the 5V supply is well decoupled with at least 0.1 uF ceramic capacitors placed close to the VDD pins, and respect the 4.5V minimum VDD requirement during A/D conversions. The 50 I/O lines can source/sink up to 25 mA per pin (subject to package dissipation limits), and unused I/O pins should be configured as outputs to minimize current draw.

일반적인 애플리케이션
PIC17C752T-16I/L 적합 용도: 6 애플리케이션s: Industrial Process Control, Sensor Data Acquisition Systems, Motor Control Front-End, Embedded Data Logging, Consumer Appliance Controllers, Automotive Body Electronics (Non-Safety).
Industrial Process Control
The PIC17C752T-16I/L fits industrial process control applications because its 16 KB OTP memory, 50 I/O pins, and integrated 10-bit A/D converter provide all the resources needed for closed-loop PID control of motors, valves, and temperature sensors. Its 121 ns single-cycle instruction execution (8.25 MIPS at 16 MHz) keeps control loop latency well below typical millisecond-scale process time constants. The 68-PLCC industrial-grade package supports -40 C to +85 C operation in factory-floor environments, and the single-cycle hardware multiplier accelerates DSP-style filter computations such as moving averages and FIR filters used for signal conditioning.
추천
Sensor Data Acquisition Systems
The PIC17C752T-16I/L is well matched to multi-channel sensor data acquisition because its integrated 10-bit A/D and 50 I/O pins let designers read multiple analog sensors (temperature, pressure, flow) directly without external multiplexer ICs. The 678-byte RAM buffers sample bursts before forwarding to a host. Its single-cycle hardware multiplier (8x8) computes scaled engineering units on the fly. Industrial temperature grade and 5V operation make the part a direct fit for 4-20 mA loop-powered sensor transmitters and HVAC sensor nodes, where the 16 KB OTP holds calibration tables and linearization polynomials.
추천
Motor Control Front-End
The PIC17C752T-16I/L serves as a motor-control front-end MCU because its 8.25 MIPS throughput and single-cycle multiply handle field-oriented control (FOC) math for small brushless DC or stepper motors. The 50 I/O lines drive PWM channels, Hall-sensor inputs, and fault signals. The 10-bit A/D samples motor current via shunt resistors for torque control. Industrial-grade -40 C to +85 C operation supports outdoor pump and fan motor applications. The 16 KB OTP memory holds motor startup ramps and speed profiles, while the 5V I/O simplifies interface to legacy gate drivers.
추천
Embedded Data Logging
The PIC17C752T-16I/L supports embedded data logging applications because its 16 KB OTP holds time-stamped logging routines, calibration data, and small lookup tables, while 678 bytes of RAM buffer samples before flushing to external EEPROM or SD cards via SPI. The 10-bit A/D captures analog process variables; the UART/SPI peripherals push data to a host. Industrial -40 C to +85 C operation supports unattended remote telemetry units in outdoor cabinets. The 50 I/O lines drive status LEDs, user buttons, and RTC interrupt lines without external I/O expanders.
추천
Consumer Appliance Controllers
The PIC17C752T-16I/L is used in mid-volume consumer appliance controllers (washing machines, dishwashers, microwave ovens) because the OTP memory locks the firmware at production time, preventing field tampering. Its 50 I/O pins drive seven-segment displays, keypads, relays, and buzzer drivers directly. The integrated 10-bit A/D reads temperature and humidity sensors for cycle control. The 5V supply is compatible with legacy triac-driving optocouplers and zero-cross detectors. The 68-PLCC package is socket-friendly for factory programming and field service.
추천
Automotive Body Electronics (Non-Safety)
The PIC17C752T-16I/L fits non-safety automotive body-electronics applications such as HVAC blend-door actuators, seat-position memories, and mirror controllers where its 50 I/O lines, 10-bit A/D, and industrial temperature grade meet the requirements. The 5V supply is compatible with body-controller 12V-bus post-regulator rails. Although not AEC-Q100 qualified (this part is NRND and predates automotive qualification programs), existing automotive designs using the PIC17C752 may continue production through Microchip's longevity program. For new designs, the recommended replacement is PIC18F6520 with proper AEC-Q100 screening.

설계 노트
The PIC17C752T-16I/L requires a regulated 4.5 V to 5.5 V supply with adequate decoupling. Place a 0.1 uF ceramic capacitor as close as possible to each VDD/AVDD pin pair (pins 13/31/44/59 for VDD and 66 for AVDD), and add a single 10 uF bulk tantalum or aluminum electrolytic capacitor near the MCU. For A/D accuracy, keep AVDD and VDD on the same regulator output and ensure the trace between them is short. The A/D VREF+ pin (68) should be bypassed with 0.1 uF to ground.
Route the 16 MHz crystal traces (OSC1/OSC2, pins 1-2) as short as possible, no longer than 5 mm, with a ground guard ring. Keep the crystal case grounded. For PLCC-68 socketed designs, use a machined-pin socket (e.g., 3M Textool) for reliable field replacement - the standard stamped PLCC sockets may fail thermal cycling. If using a socket, include a small 100 nF decoupling capacitor directly under the socket on each VDD pin.
Do not program the PIC17C752 OTP twice - the memory cells can be written only once. Use the Microchip PM3 universal programmer or an approved OTP programming tool, and verify the configuration bits before locking. Unused I/O pins should be configured as outputs and tied low to minimize supply current. The MCLR pin (3) must be pulled high through a 10 kohm resistor for normal operation; leaving it floating causes intermittent resets.
For designs switching more than 8 I/O lines simultaneously, add a 100 ohm series resistor near each output pin to dampen transmission-line ringing on cables. The 50 I/O pins source/sink up to 25 mA each but the package dissipation limit (typically 1 W total) must not be exceeded - calculate worst-case power across all outputs. The A/D converter input impedance is several kohm, so add an external buffer if the source impedance exceeds 2.5 kohm to avoid conversion errors.
