PIC17C752T-16/PT - 16MHz 8-bit OTP MCU, 16KB, TQFP-64 | Microchip
MPN: PIC17C752T-16/PT ✗ Cuối đờiPIC17C752T-16/PT Tóm tắt
Background: A PIC (Peripheral Interface Controller) microcontroller is a Harvard-architecture RISC device that separates program and data memory, enabling simultaneous instruction fetch and operand access for high-throughput deterministic execution. The PIC17C family represents Microchip's high-performance 8-bit tier, positioned above the PIC16C and PIC12C families in computational throughput and peripheral integration, while remaining within the broader 8-bit microcontroller category of embedded processing ICs.
Key features include an 8.25 MIPS instruction execution rate at 16 MHz (121 ns single-cycle instruction time), only 58 single-word instructions for compact code authoring, and 4.5 V to 5.5 V single-supply operation. Two-cycle branches and table reads/writes extend to roughly 242 ns. The device includes programmable code protection, power-on reset, brown-out reset, watchdog timer with its own on-chip RC oscillator, dual analog comparators, and three timer/counter modules. The 64-pin TQFP package provides a thin (~1 mm) profile suitable for space-constrained PCB designs.
Typical applications span industrial automation controllers, consumer electronics user interfaces, medical device subsystems, and embedded control modules. The generous 50-I/O count suits keypad scanning, LCD driving, and parallel sensor aggregation. The integrated communication peripherals enable master/slave roles on multi-drop buses, while the OTP program memory supports volume production with one-time firmware commit at lower unit cost than flash parts.
Design consideration: at 16 MHz, the PIC17C752 operates at the upper boundary of its 5 V supply range; ensure decoupling caps are placed within 5 mm of VDD pins, and use a low-ESR ceramic (100 nF plus 10 uF bulk) layout. This device is recommended for new designs only when PIC18F or dsPIC33 alternatives are unavailable, as the manufacturer explicitly directs users to the PIC18F6520 successor.

Ứng dụng tiêu biểu
PIC17C752T-16/PT phù hợp cho 6 Áp dụngs: Industrial Automation Controllers, Consumer Electronics User Interfaces, Medical Device Subsystems, Embedded Control Modules, Automotive Body Electronics, Instrumentation and Test Equipment.
Industrial Automation Controllers
The PIC17C752T-16/PT is well-suited for industrial automation controllers that require deterministic 8-bit RISC execution, robust I/O expansion, and integrated serial communication. With 16 KB OTP program memory and 8.25 MIPS throughput at 16 MHz, the MCU can run multi-axis stepper-motor state machines, PID control loops, and HMI keypad scanning routines in real time. The 50 digital I/O pins allow direct connection to relay banks, optocoupler-isolated inputs, and 7-segment displays without external I/O expanders. The integrated I2C, SPI, and UART/USART peripherals enable master/slave roles on RS-485 multi-drop fieldbus networks and inter-MCU links within the same cabinet. Designers should pair each VDD/SS pair with 100 nF ceramic decoupling plus a 10 uF bulk capacitor to suppress noise from 24 V solenoid switching.

Consumer Electronics User Interfaces
For consumer appliance user interfaces (washing machines, microwave ovens, air conditioners), the PIC17C752T-16/PT offers 50 I/O that can directly drive 4x5 key matrices, multiple 7-segment LED displays, and character LCD modules. Its 16 MHz core clocks 121 ns instructions, supporting debounced keypad scan loops and display refresh tasks simultaneously without RTOS overhead. On-chip I2C and SPI allow pairing with EEPROM for user settings, audio DACs for chime generation, and temperature/humidity sensors for environmental feedback. OTP program memory at 16 KB enables cost-optimized high-volume SKUs where firmware is finalized and one-time programmed during manufacturing. The TQFP-64 footprint enables compact front-panel PCB layouts with hand-solder-friendly gull-wing leads.

Medical Device Subsystems
Medical device subsystems (non-life-support, such as blood-pressure monitors, infusion-pump user interfaces, and diagnostic-reader keypad controllers) can leverage the PIC17C752T-16/PT for its deterministic instruction timing and on-chip analog comparators. The 8.25 MIPS throughput supports sensor-acquisition routines, filter math, and graphic-LCD updates in parallel. Brown-out reset and watchdog timer with dedicated RC oscillator provide defense-in-depth against firmware lockups required by IEC 60730 class B compliance. The 678 B RAM accommodates 16-bit ADC buffering from external converters and rolling-average filters. Designers should validate electromagnetic compatibility per IEC 60601-1-2, since the 16 MHz oscillator harmonics can couple into nearby analog front-end stages.

Embedded Control Modules
Embedded control modules such as vending-machine controllers, access-control panels, HVAC zone controllers, and building-automation nodes benefit from the PIC17C752T-16/PT's combination of 16 KB OTP, 50 I/O, and three hardware timers. The MCU can drive character LCDs, scan 4x4 keypads, control relay outputs, and poll multiple UART peripherals concurrently. The hardware UART/USART enables direct RS-232/RS-485 communication with host systems, while I2C and SPI support sensor and memory expansion. OTP memory locks the firmware at production time, preventing field tampering with security-sensitive algorithms. The 4.5 V to 5.5 V supply range is well-matched to 5 V regulated industrial rails without level shifters.

Automotive Body Electronics
Automotive body-electronics modules (interior lighting controllers, seat-position memory, mirror adjusters, and instrument-cluster auxiliary logic) historically used the PIC17C752 family for its multi-I/O capability and 5 V operation. Although this part is NRND and not AEC-Q100 qualified, it has been deployed in commercial-vehicle and aftermarket designs. The 50 I/O supports multiple H-bridge drivers, switch-scan matrices, and CAN/LIN gateways via external transceivers. Designers moving to new designs should consider AEC-Q100-qualified successors such as PIC18F46K22 or dsPIC33EP64MC204. For legacy aftermarket replacement, the PIC17C752-16I/PT (industrial temperature) provides an automotive-suitable temperature grade with identical pinout.

Instrumentation and Test Equipment
Bench instrumentation and test equipment, including laboratory data-loggers, hand-held multimeter front-ends, and educational measurement kits, can use the PIC17C752T-16/PT for measurement acquisition, range-switching logic, and LCD or 7-segment display driving. The hardware timers support precise frequency-counter and event-counter functions, while the analog comparators enable window-discriminator and zero-crossing detection. The 50 I/O directly multiplex multiple measurement ranges and signal-conditioning relays without external logic. The 16 KB program memory fits structured C code for calibration tables, linearization math, and serial-protocol command parsing. Designers should add external ESD protection on user-accessible connectors since OTP firmware cannot be patched in the field.

Ghi chú thiết kế
Place a 100 nF low-ESR ceramic decoupling capacitor within 5 mm of each VDD/VSS pin pair (5 pairs on TQFP-64) and a single 10 uF bulk tantalum or ceramic capacitor at the board-level VDD entry point. The PIC17C752T-16/PT draws transient currents up to ~100 mA during I/O bank switching, and inadequate decoupling can cause brown-out resets or instruction-fetch corruption. Tie unused I/O pins to defined logic levels (VDD or VSS) to prevent shoot-through current and oscillator noise coupling.
Route the 16 MHz crystal traces (OSC1/OSC2) as short, symmetric pairs with a ground guard ring to minimize EMI. The PIC17C752T-16/PT is not a 5 V-tolerant device in industrial environments; add external ESD protection (TVS arrays such as USBLC6-2SC6) on any user-accessible connector pins. Keep digital switching traces away from analog comparator inputs (RA0-RA3) and route these analog signals with ground shielding. Place MCLR/VPP capacitor (typically 10-100 nF) close to the pin for proper reset behavior.
Do not assume OTP memory is erasable - each bit can only be programmed once, so firmware bugs cannot be field-patched. For new designs choose PIC18F46K22 or dsPIC33EP64MC204 (flash-based). Estimated: oscillator start-up time at 16 MHz with a typical 22 pF load crystal is 50-200 ms; wait for OST (Oscillator Start-up Timer) timeout before code execution to avoid erratic reset behavior. When migrating from PIC16C/PIC12C, note that PIC17C uses 16-bit instruction words, not 14-bit, doubling program-memory throughput per fetch.
