PIC17LC752-08/L - 8-Bit 8MHz 16KB OTP MCU 68-PLCC | Microchip
MPN: PIC17LC752-08/L ✗ اختتامِ زندگیPIC17LC752-08/L جائزہ
An EPROM-based microcontroller is a member of the broader category of microcontrollers - self-contained single-chip computers that integrate a CPU, non-volatile program memory, working RAM, and I/O peripherals. The PIC17C family sits hierarchically above 8-bit microcontrollers, within the larger class of embedded controllers, and ultimately within the integrated circuits > microcontrollers category. EPROM-based MCUs were historically used for cost-sensitive production runs where field reprogrammability was not required, and they bridge the gap between mask-ROM MCUs (lowest unit cost at high volumes) and Flash-based MCUs (re-programmability).
Key differentiating specifications of the PIC17LC752-08/L include its 16-bit-wide program memory bus (8K x 16 words), 50 high-current I/O pins suitable for direct LED or relay drive, a 33 MHz maximum clock input, and four hardware interrupt sources. Compared with PIC16-family parts, the PIC17C offers an extended instruction set with hardware multiply, a larger register file, and a wider 16-bit program-memory datapath that reduces fetch bottlenecks.
Architecturally, the device uses a Harvard architecture with separate program and data paths, a hardware multiply unit, and a multi-source interrupt controller with priority levels. The OTP EPROM cell provides one-time field programming via standard EPROM programmers, and the part is qualified for commercial-temperature operation.
Typical applications include industrial control panels, instrumentation front-ends, motor control firmware prototypes, HVAC controllers, point-of-sale terminals, and embedded control boards in commercial equipment where moderate I/O count and 8-bit processing suffice.
When designing with this device, note that the OTP memory cannot be re-programmed in-circuit, so firmware must be fully validated before final programming. Allocate one hardware timer for the watchdog to detect firmware lock-ups, and consult the Microchip PIC17C family reference manual for the exact timer-to-peripheral mapping.

عام استعمالات
PIC17LC752-08/L کے لیے موزوں ہے 6 ایپلیکیشنs: Industrial Control Panel, Motor Control Firmware Prototype, HVAC Thermostat Controller, Point-of-Sale Terminal, Test and Measurement Instrumentation, Embedded Control Board - Commercial Equipment.
Industrial Control Panel
The PIC17LC752-08/L's 50 general-purpose I/O pins, 33 MHz clock input, and 11-channel 10-bit ADC suit industrial control panels that scan keypads, drive LED/LCD indicators, and read analog sensor inputs such as temperature or pressure. Its 16KB OTP program memory accommodates mid-sized control firmware with state machines, and the 678-byte RAM supports moderate data buffering. Operated from a 3.3V or 5V industrial rail, the part delivers deterministic 121 ns instruction execution. Companion parts include a low-dropout regulator such as the LM7805 for the 5V rail, an RS-232/RS-485 transceiver for panel-bus connectivity, and an EEPROM like 24LC256 for parameter storage.

Motor Control Firmware Prototype
For motor-control prototypes the PIC17LC752-08/L's two 16-bit timers with PWM/capture/compare peripherals, plus 50 I/O for gate-drive and feedback signals, allow direct control of small DC or stepper motors. The 33 MHz clock input and 16-bit datapath execute fast inner-loop PID computations, while the hardware multiply unit accelerates control-law math. Designers should pair the MCU with a dedicated gate driver such as the IR2110 and Hall-sensor conditioning circuitry. The OTP memory is acceptable for prototypes where firmware is mature; switch to a Flash-based dsPIC33 for production.

HVAC Thermostat Controller
The PIC17LC752-08/L's integrated 10-bit ADC measures thermistor or RTD inputs for indoor/outdoor temperature sensing, while the USART interfaces to a Wi-Fi or sub-GHz module for remote telemetry. With 16KB of OTP firmware storage, the MCU can host scheduling logic, PID loops, and LCD/segment-display drivers. Its commercial 0C to +70C temperature range covers indoor HVAC enclosures. Companion parts include a 24LC256 EEPROM for setpoint backup, an SPI-segment LCD driver, and a relay-driver array for compressor and fan control.

Point-of-Sale Terminal
Point-of-sale terminals require an MCU that can drive a character LCD, scan a keypad matrix, and communicate over RS-232 to a receipt printer or back-office terminal. The PIC17LC752-08/L provides 50 I/O pins for keypad scanning and LCD interface, a USART for printer connectivity, and 16KB of OTP memory for transaction-logic firmware. Its 33 MHz throughput handles encryption-light operations and barcode-decoder algorithms. Note that OTP memory requires final firmware to be fully validated before programming - use a Flash-based PIC18F4550 for development and final migration.

Test and Measurement Instrumentation
Bench-top test instruments such as digital panel meters, frequency counters, and laboratory data loggers benefit from the PIC17LC752-08/L's 33 MHz throughput, 11-channel 10-bit ADC, and large I/O count for front-panel switches and 7-segment displays. The 16-bit datapath accelerates DSP-light filtering, while the OTP memory ensures firmware integrity in metrology applications. For higher-resolution ADCs, the MCU's SPI interface can connect to external 16-bit converters such as the ADS1115. Pair the MCU with a precision voltage reference like the REF5025 for ratiometric measurements.

Embedded Control Board - Commercial Equipment
Commercial equipment such as vending machines, washing-machine controllers, and access-control panels require reliable embedded control with a moderate code footprint. The PIC17LC752-08/L's 16KB OTP memory, 50 I/O, and 2.5V to 5.0V supply flexibility support coin/bill validator interfaces, solenoid drivers, keypad scanning, and LCD display. Its NRND status makes it appropriate for re-spinning existing designs rather than starting new ones; new designs should target Microchip's Flash-based PIC18F or dsPIC33 family. Companion parts include a watchdog supervisor like the MCP130 and a 24LC256 EEPROM for transaction audit trails.

ڈیزائن نوٹس
The PIC17LC752-08/L uses OTP (One-Time-Programmable) EPROM memory that cannot be erased or re-programmed in-circuit. Validate firmware on a PIC17C44 or PIC17LC44 development equivalent before committing to the LC752 silicon. Once programmed, every silicon revision or bug fix requires a new chip and re-programming of all units in the field.
The LC variant operates from 2.5V to 5.0V; the standard C variant (e.g. PIC17C752-16/L) requires 4.5V to 6.0V and will not function at 3.3V rails. Decouple VDD with a 0.1uF ceramic capacitor placed within 5 mm of the VDD pin, plus a bulk 10uF tantalum or aluminum polymer cap near the package. The 68-PLCC has multiple VDD/VSS pins that must all be connected.
The 68-PLCC (24.23 x 24.23 mm) package is a J-lead surface-mount format suitable for standard SMT assembly, but its lead pitch is 1.27 mm, requiring careful solder-paste stencil design. For prototype breadboarding, use a PLCC-to-DIP adapter socket. Ensure the ICSP programming header (MCLR, RB6, RB7, VDD, VSS) is accessible on the PCB for factory programming of the OTP memory.
