PIC17C752T-33/PT - 8-bit 33MHz OTP MCU 16KB TQFP-64 | Microchip
MPN: PIC17C752T-33/PT ✗ Cuối đờiPIC17C752T-33/PT Tóm tắt
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory (ROM/Flash/OTP), data RAM, and programmable peripherals such as timers, communication interfaces, and analog-to-digital converters. Within the broader semiconductor taxonomy, MCUs sit under microcontrollers -> microprocessors -> integrated circuits -> semiconductors. The PIC17C family represents Microchip's high-performance 8-bit line, bridging the gap between classic PIC16 devices and the later PIC18 generation, and historically targeted applications needing higher throughput than the PIC16 but without stepping up to a 16-bit dsPIC core.
Key features include a Harvard-architecture RISC core with a multi-stage instruction pipeline, an 8-bit data path, 33 MHz clock speed, 16 KB OTP program memory (8K x 16 words), and 454 x 8 bytes of RAM. On-chip peripherals include multiple timers, capture/compare/PWM modules, and serial communication interfaces such as I2C, SPI, and UART/USART. The device operates from 4.5 V to 5.5 V across the commercial temperature range.
The architecture separates program and data memory spaces, allowing instruction fetch and operand read to occur in a single cycle. The OTP memory is programmed once and retains the bit pattern permanently, which makes the PIC17C752T-33/PT well suited to mature production designs that do not require firmware updates.
Typical applications include industrial control systems, motor control front-ends, embedded instrumentation, security and access control panels, and consumer appliance controllers that need reliable 8-bit processing at moderate clock speeds.
When designing with this part, note that OTP memory cannot be reprogrammed, so firmware must be fully validated on prototype parts (such as the EPROM-windowed PIC17C756) before committing to production. Verify your tooling supports the PIC17C instruction set and that your in-circuit programmer is compatible with the 64-pin TQFP land pattern.

Ứng dụng tiêu biểu
PIC17C752T-33/PT phù hợp cho 6 Áp dụngs: Industrial Motor Control, Embedded Instrumentation, Security and Access Control Panels, Consumer Appliance Controllers, Automotive Body and Comfort Modules, Point-of-Sale Terminals and Printers.
Industrial Motor Control
The PIC17C752T-33/PT's 33 MHz RISC core delivers 121 ns instruction cycle time, fast enough to implement field-oriented control (FOC) loops and trapezoidal commutation for small BLDC and stepper motors at update rates above 20 kHz. Its on-chip capture/compare/PWM peripherals generate the multi-channel switching waveforms directly without an external timer IC, while the 16 KB OTP program memory holds sensorless startup routines and current PI-loop coefficients. The 5 V supply tolerates the harsh 24 V industrial bus after regulation, and the 64-pin TQFP exposes enough I/O for three-phase gate drivers plus encoder feedback and CAN-bus or UART diagnostics.

Embedded Instrumentation
Laboratory instruments such as bench multimeters, signal generators, and process calibrators benefit from the PIC17C752T-33/PT's deterministic 8-bit core and 33 MHz throughput for fixed-point DSP routines like RMS calculation, FIR filtering, and thermocouple linearization. The on-chip I2C/SPI/UART ports connect directly to ADC front-ends, LCD modules, and EEPROM calibration storage. OTP memory is acceptable because once the calibration constants and UI logic are frozen, the firmware is rarely updated. The 454-byte RAM is tight, so engineers typically offload display buffers to external SRAM via the external memory interface.

Security and Access Control Panels
Access control and alarm panels run deterministic scanning loops over keypads, card readers, and supervised sensor loops - a workload that fits naturally on the PIC17C752T-33/PT's 33 MHz PIC17C core. The three on-chip serial ports (I2C, SPI, UART/USART) drive external Ethernet or GSM modules, while the 16 KB OTP program memory holds encrypted credential tables and event-logging state machines. The commercial 0C to +70C temperature range covers indoor enclosures, and the 64-pin TQFP leaves enough I/O for keypad scanning, LED drivers, and supervised siren outputs.

Consumer Appliance Controllers
White-goods controllers for washing machines, dishwashers, and induction cooktops leverage the PIC17C752T-33/PT's 33 MHz throughput to run multi-state machine control, sensor fusion, and user-interface logic on a single chip. OTP memory locks the appliance firmware against unauthorized reflash, which is a regulatory requirement in many markets. The on-chip PWM peripherals drive triac-fired heater elements and variable-frequency motor stages, while I2C/SPI/UART connect to display boards, temperature sensors, and inverter bridges. The 64-pin TQFP package handles the high pin count needed for keypad, LED, relay, and sensor wiring.

Automotive Body and Comfort Modules
Body controllers for window lifters, seat adjusters, mirror modules, and HVAC actuators use the PIC17C752T-33/PT's 33 MHz core to manage multiple LIN-networked actuators and run PWM-controlled DC motor drivers. Although the PIC17C752T-33/PT is commercial grade (0C to +70C), the family supports the PIC17C752-33E/PT extended-temperature variant rated -40C to +125C, making it suitable for cabin-mounted modules. The 16 KB OTP program memory and 454-byte RAM are sufficient for body-control firmware with limited diagnostics. New designs requiring AEC-Q100 qualification should migrate to dsPIC33 or PIC18F K-series parts.

Point-of-Sale Terminals and Printers
POS terminals, receipt printers, and barcode scanners rely on deterministic I/O handling rather than raw compute power - exactly the design sweet spot for the PIC17C752T-33/PT's 8-bit PIC17C core. The three serial channels (I2C, SPI, UART/USART) drive keypad, magnetic-stripe reader, thermal print head, and cash-drawer kick without external logic. OTP memory is acceptable because once a POS firmware revision is certified, it is rarely changed. The 64-pin TQFP leaves enough I/O for LCD, status LEDs, and multiple peripheral connectors typical of retail equipment.

Ghi chú thiết kế
The PIC17C752T-33/PT operates from 4.5 V to 5.5 V and draws roughly 50 mA at 33 MHz with all peripherals active. Place a 100 nF ceramic decoupling capacitor within 5 mm of each VDD/VSS pin pair, plus a single 10 uF bulk tantalum or ceramic capacitor at the regulator output. AVSS and VSS must be tied together at a single low-impedance ground point to avoid ADC reference offset.
Route the OSC1/OSC2 crystal traces as short, symmetric differential pairs and guard them with a ground pour to prevent noise coupling into the 33 MHz system clock. Keep the MCLR/VPP pin trace short to the reset supervisor; long traces pick up ESD transients that can cause spurious resets during in-circuit programming. The 64-pin TQFP has 0.5 mm pitch - ensure your PCB house can reliably fabricate this fine pitch (most can, but verify the aperture and solder-mask registration).
PIC17C752T-33/PT uses OTP memory, which cannot be erased or reprogrammed. A single bit error in programming permanently bricks the part. Always prototype with the EPROM-windowed PIC17C756 first, then commit final firmware to PIC17C752 production units. Estimated: typical OTP programming time at 13.5 V VPP is 3-5 ms per word, so a 16 KB image takes roughly 30-60 seconds to program, during which MCLR must remain asserted and VDD must stay within regulation.
