PIC17C756AT-33E/L - 8-Bit 33MHz OTP MCU 32KB | 68-PLCC
MPN: PIC17C756AT-33E/L ✗ اختتامِ زندگیPIC17C756AT-33E/L جائزہ
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory (ROM/Flash/OTP), data memory (RAM), and programmable I/O peripherals. The 8-bit PIC17C architecture sits at the top of Microchip's original 8-bit hierarchy (PIC16 -> PIC17 -> PIC18), offering expanded peripherals, linear memory addressing, and faster execution than the popular PIC16 family, while predating the flash-based PIC18F successors.
Key features include 50 digital I/O pins, an internal 8-bit data bus with 16-bit instruction path, 8 MIPS sustained throughput, an analog comparator module, capture/compare/PWM, USART, and an 8-channel 10-bit ADC. The OTP program memory allows factory or volume one-time programming for production runs, making this part well suited for mature industrial designs. Only 58 single-word instructions need to be learned, simplifying firmware development.
Typical applications include industrial automation controllers, automotive body and chassis electronics, consumer appliances with keypad/display interfaces, and embedded control of legacy PIC-based systems. The wide 4.5 V to 5.5 V supply range and 50 I/O channels make it suitable for motor control front-ends, sensor aggregation nodes, and human-machine interface (HMI) boards. Its 33 MHz throughput comfortably handles real-time control loops, UART bridging, and PWM-driven actuators.
When designing with this part, ensure the OTP programming step is factored into production logistics and that adequate decoupling (100 nF + 10 µF) is placed close to VDD pins. Designers migrating to a flash-based equivalent should evaluate Microchip's recommended successor (PIC18F6520) since PIC17C parts are not recommended for new designs.

Industrial Automation Controllers
The PIC17C756AT-33E/L fits industrial PLC and machine-controller boards where its 50 digital I/O channels, 8.25 MIPS throughput, and -40 °C to +125 °C extended temperature grade ensure reliable operation on factory floors. Its 32 KB OTP holds ladder-logic-equivalent state machines and PID loop code, while the 902-byte RAM is ample for sensor-fusion buffers and communication stacks. The 33 MHz CPU comfortably services RS-485/USART polling of remote I/O at sub-millisecond cycle times.

Automotive Body Electronics
PIC17C756AT-33E/L's automotive-grade extended temperature rating (-40 °C to +125 °C) and 50 I/O make it suitable for body controllers managing lighting, door modules, seat controllers, and climate subsystems. The 33 MHz core executes CAN-style message debouncing, PWM-driven mirror/headlamp control, and LIN-bus state machines in real time. OTP memory locks firmware against unintended field reprogramming in safety-relevant modules.

Consumer Appliance Control
PIC17C756AT-33E/L's 32 KB OTP and 50 I/O deliver cost-effective control for washing machines, microwave ovens, dishwashers, and HVAC indoor units. The MCU drives keypads, character LCDs via I/O expansion, triac-fired loads through zero-cross detection, and sensor interfaces for temperature/pressure monitoring. OTP programming locks production firmware and prevents unauthorized cloning of branded appliance algorithms.

Human-Machine Interface (HMI) Boards
The PIC17C756AT-33E/L drives 4x4 keypads, rotary encoders, LED/LCD status indicators, and segment displays in industrial HMI terminals. With 50 I/O and 8.25 MIPS, the MCU scans key matrices at >100 Hz, debounces mechanical contacts, and refreshes multiplexed 7-segment or character displays without flicker. The 902-byte RAM holds menu state and input buffers.

Sensor Aggregation Nodes
PIC17C756AT-33E/L aggregates inputs from multiple analog and digital sensors in environmental monitoring and building automation. The 8-channel 10-bit ADC handles thermistor, photocell, and 4-20 mA transducer inputs, while USART and I/O ports forward conditioned data to upstream controllers. The 33 MHz CPU runs digital filters (averaging, peak detection) without burdening host systems.

Legacy PIC17C System Repair/Maintenance
PIC17C756AT-33E/L is the canonical replacement for legacy PIC17C-based equipment in field service operations. Its identical silicon and 68-PLCC package allow direct board-level swap into industrial controllers, scientific instruments, and medical devices originally built around the PIC17C756A. Maintaining a small inventory of this OTP MCU supports 10-15 year service contracts on deployed systems where redesign is uneconomical.

ڈیزائن نوٹس
PIC17C756AT-33E/L requires a stable 4.5 V to 5.5 V supply. Place a 10 µF bulk electrolytic or tantalum and a 100 nF ceramic decoupling capacitor within 5 mm of each VDD pin pair. The 68-PLCC has multiple VDD/VSS pairs (pins 13/12, 31/30, 41/40, 51/50, 61/60) that must each be decoupled - poor decoupling causes ADC noise and brown-out resets. Use a ferrite bead on the analog AVDD rail if present in your schematic.
Do not confuse the OTP (PIC17C) family with the flash (PIC17F) or PIC18F families - code compiled for PIC17C will not run on PIC18F and vice versa. When migrating legacy code, recompile with the PIC18F compiler. OTP parts can only be programmed once - verify firmware with a windowed PIC17C756A version (PIC17C756A-EMR family) before committing to OTP production units.
PIC17C756AT-33E/L in 68-PLCC has a thermal resistance of approximately 50 °C/W (junction-to-ambient, still air) per Microchip plastic-package thermal data. At maximum clock and full I/O switching, power dissipation stays well under 500 mW. The PLCC package's top surface allows socket insertion for prototypes - useful for field-service repair kits where the MCU is field-swappable.
