PIC17C752-16I/PT 개요
A PIC microcontroller (Programmable Interface Controller) is a family of 8/16/32-bit RISC microcontrollers built around a Harvard architecture with separate program and data memory buses, designed for embedded control applications. PIC MCUs sit within the broader category hierarchy of microcontroller -> embedded processor -> semiconductor device, and the PIC17C sub-family is one of Microchip's high-performance 8-bit lines positioned between the baseline PIC16 and the 16-bit dsPIC/PIC24 families. The "C" suffix denotes EPROM/OTP program memory (One-Time Programmable), which is well suited to prototyping and low-volume production.
Key features include only 58 single-word instructions for fast code ramp-up, single-cycle hardware multiplication, dual-cycle program branches and table read/write operations, four capture inputs for timing measurements, three PWM outputs for motor or power control, and an external memory bus that allows the 16 KB of internal program memory to be expanded. The -I suffix denotes the industrial operating temperature range, allowing the device to operate from -40C to +85C ambient.
Typical applications include industrial automation controllers, motor control systems, HVAC interface panels, security and access-control panels, instrumentation front-ends, and sensor aggregation hubs where the on-chip 10-bit ADC, PWM, and capture peripherals reduce total BOM. Microchip explicitly recommends the newer PIC18F6520 as the modern migration path for new designs, indicating that the PIC17C752 is now a mature legacy line maintained primarily for installed-base designs.
When designing with this part, ensure the EPROM windowed parts (JW package) are reserved only for prototype development because once programmed under the UV-erasable window they cannot be reprogrammed without erasure. Use the on-chip UART and SSP peripherals to offload communication and reduce firmware complexity, and provide adequate decoupling (0.1 uF + 10 uF bulk) near both VDD pins to support the high-current transients of the EPROM read and the ADC conversion clock.

일반적인 애플리케이션
PIC17C752-16I/PT 적합 용도: 6 애플리케이션s: Industrial Automation Controllers, Motor Control and PWM Drive Systems, HVAC Control Panels, Security and Access-Control Panels, Instrumentation Front-Ends, Sensor Aggregation Hubs.
Industrial Automation Controllers
The PIC17C752-16I/PT fits industrial automation controllers because its 16 KB OTP memory and 50 I/O lines are sufficient for sequencing relays, reading limit switches, and driving indicator panels without external bus expansion. The 12-channel 10-bit ADC handles analog sensor inputs (pressure, temperature, level) directly, and the three PWM outputs plus four capture inputs simplify closed-loop motor and valve control. The 4.5 V to 5.5 V supply and -40 C to +85 C industrial temperature grade support factory-floor operation, while the SSP (SPI/I2C) and two USARTs enable integration with HMIs, PLCs, and fieldbus gateways. The 64-pin TQFP footprint provides enough GPIO to drive parallel LCDs or keypad matrices.
추천
Motor Control and PWM Drive Systems
The PIC17C752-16I/PT suits motor control designs because it integrates three dedicated PWM channels and four capture inputs alongside the 8.25 MIPS core, enough to implement trapezoidal or sinusoidal commutation on small BLDC or stepper motors. The 12-channel 10-bit ADC samples back-EMF and current-sense signals, while the single-cycle 8x8 hardware multiplier accelerates PI loop calculations. With a 121 ns instruction cycle the controller can service a 20 kHz PWM rate plus feedback sampling within tight interrupt latency. The 64-pin TQFP exposes enough I/O to drive three half-bridges plus encoder feedback directly.
추천
HVAC Control Panels
The PIC17C752-16I/PT is well matched to HVAC control panel logic because its 50 I/O lines and SSP peripherals can directly scan keypads, drive character LCDs, and interface with temperature/humidity sensors via SPI or I2C. The 10-bit ADC is adequate for thermistor and pressure-transducer conditioning, and the four capture inputs handle AC zero-cross detection for triac-fired heater elements. The industrial -40 C to +85 C temperature range tolerates equipment-room environments, while the EPROM/OTP memory suits long-lifecycle HVAC products where firmware rarely changes after release. PIC18F6520 is the recommended Flash-based successor for new SKUs.
추천
Security and Access-Control Panels
The PIC17C752-16I/PT supports security and access-control panels by combining 50 I/O lines for keypad matrix, door-strike relays, and zone-status LEDs with two USARTs for connecting to central-station modems or local RS-485 keypads. The 16 KB OTP memory is large enough to store user credential tables and event logs, while the 10-bit ADC monitors backup battery voltage and tamper-loop currents. The 4.5 V to 5.5 V supply matches common 5 V regulated alarm-bus rails, and the industrial temperature range survives unheated equipment closets. The SSP port supports secure EEPROM credential storage via SPI.
추천
Instrumentation Front-Ends
The PIC17C752-16I/PT works well as an instrumentation front-end controller because its 12-channel 10-bit ADC and the 8.25 MIPS core can scan multiple analog inputs, apply linearization, and drive character displays. The four capture inputs handle frequency-to-voltage measurements from flow meters or tachogenerators, while the SSP (SPI/I2C) and two USARTs allow connection to laboratory data loggers, PC-based calibration tools, or remote sensor heads. The 64-pin TQFP provides 50 I/O lines for relay multiplexers, range-selection switching, and front-panel switches without external bus expansion.
추천
Sensor Aggregation Hubs
The PIC17C752-16I/PT serves as a sensor-aggregation hub because it can simultaneously sample up to 12 analog channels via the on-chip 10-bit ADC while running SPI or I2C master transactions to additional digital sensors on the SSP bus. The 50 I/O lines support multiple 4-20 mA loops, discrete status inputs, and actuator drive outputs in parallel, while the two USARTs provide redundant uplink paths to a central controller or modem. The 678 bytes of RAM buffer bursty sensor traffic, and the industrial -40 C to +85 C range tolerates outdoor or factory-cabinet deployments where PIC17C legacy designs are still common.

설계 노트
The PIC17C752-16I/PT has two VDD pins (13 and 31) and two VSS pins (12 and 30) plus a separate analog AVDD/AVSS pair (60/59); both digital supplies must be connected with their own 0.1 uF ceramic decoupling placed within 5 mm of each pin, plus a single 10 uF bulk tantalum or ceramic at the regulator. EPROM read operations produce sharp current transients on the order of 30 to 50 mA peak; insufficient bulk capacitance will cause VDD sag during reads and potential EPROM read errors. The analog AVDD pin should be filtered separately with a ferrite bead or 10 ohm resistor plus 0.1 uF + 10 uF to keep ADC reference noise below 1 LSB.
EPROM/OTP memory can be programmed only once, so prototype designs must use the windowed (JW) ceramic package variant. Once sealed in the OTP -I/PT plastic TQFP, any firmware bug forces board rework. For production firmware development, follow this sequence: (1) develop and debug on a JW part, (2) verify UV-erase cycle, (3) order the production -I/PT parts only after the final firmware revision is locked. Additionally, the PIC17C family's 4x PLL means an 8 MHz external crystal produces 33 MHz internal; do not exceed the 33 MHz internal frequency maximum even with a faster external clock.
Route the 50 I/O lines on the PIC17C752-16I/PT away from the oscillator traces and the MCLR pull-up to avoid injecting switching noise into the clock or reset paths. Place the 4x PLL bypass capacitor (typically specified in the datasheet at 0.1 uF between OSC1 and ground) as close to pins 1 and 2 as physically possible. The 64-pin TQFP (10x10 mm) has 0.5 mm pitch - use 0.15 mm trace/space design rules with 0.2 mm vias under the package if escape routing is tight. Tie MCLR (pin 3) high through a 10 kohm resistor to VDD with a 100 nF capacitor to ground for noise immunity.
규정 준수 정보
RoHS, REACH, lead-free, and halogen-free status not present in the verified distributor data and marked as [DATA_NEEDED]. Microchip publishes a current C of C on the product page that should be requested before shipping product into the EU or California markets. The PIC17C family was launched before RoHS-2 (2011); original lots are likely non-compliant, but lead-free PT package variants exist on request.
