PIC17LC752T-08I/L - 8-bit 8MHz 16KB OTP MCU 68-PLCC | Microchip
MPN: PIC17LC752T-08I/L ✓ Hoạt độngPIC17LC752T-08I/L Tóm tắt
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, non-volatile program memory, working RAM, and a configurable set of peripheral interfaces. PIC microcontrollers use a Harvard RISC architecture with separate program and data buses, positioning them in the hierarchy: PIC17 -> PIC microcontroller -> 8-bit MCU -> microcontroller -> embedded processor -> semiconductor. The PIC17C/LC family sits at the high end of Microchip's 8-bit portfolio, targeting applications requiring more I/O, more memory, and faster execution than the PIC16 family.
Key features of the PIC17LC752T-08I/L include a 12-channel, 10-bit-resolution Analog-to-Digital (A/D) converter for sensor interfacing, plus three serial communication peripherals: I2C, SPI, and UART/USART. The 'LC' suffix denotes a low-voltage CMOS variant with a 2.5 V to 5.5 V supply range, making it suitable for both 3.3 V and 5 V designs. The 68-pin PLCC footprint gives the designer 50 general-purpose I/O lines, two 8-bit timer/counters, one 16-bit timer/counter, a hardware multiply, and a wide array of interrupts.
Architecturally, the PIC17 core uses a 16-bit program word with an 8-bit data path, providing 8 K words of program memory in this 16 KB device. The OTP memory is factory-one-time-programmable - not field-reprogrammable - so the part is suited for production-volume, cost-sensitive embedded products rather than iterative prototyping.
Typical applications include industrial control boards, motor-control front-ends, instrumentation front panels, and embedded networking nodes that need multiple serial channels and a moderate-resolution ADC. Because of its 5 V tolerance and rich peripheral set, this MCU is also seen in legacy telecommunication equipment, point-of-sale terminals, and printers.
When laying out a board, allocate a 0.6-inch (15.24 mm) PLCC socket footprint for prototyping; production boards typically solder the part directly. The PLCC package has J-leads on all four sides, so a socket can simplify rework. Use a 20 MHz resonator on OSC1/OSC2 even though the rated maximum is 8 MHz, to allow headroom for configuration-bit selection.

Ứng dụng tiêu biểu
PIC17LC752T-08I/L phù hợp cho 7 Áp dụngs: Industrial Control Boards, Motor Control Front-Ends, Instrumentation and Front Panels, Embedded Networking Nodes, Point-of-Sale Terminals, Legacy Printer and Display Controllers, Telecommunication Line Cards.
Industrial Control Boards
The PIC17LC752T-08I/L fits industrial control boards that need a high count of digital I/O lines and on-board analog sensing. With 50 GPIO pins, a 12-channel 10-bit ADC, and a 2.5 V to 5.5 V supply range that tolerates 24 V-derived 5 V rails, the MCU can directly read thermocouples, switch contacts, and 4-20 mA loop shunts. The I2C and SPI peripherals attach EEPROM for parameter storage and UART/USART talks to a remote HMI. Its -40C to +85C industrial temperature grade meets the IEC 60068 environmental expectations of factory-floor cabinets.

Motor Control Front-Ends
Use the PIC17LC752T-08I/L as the front-end controller in small brushed-DC and stepper motor driver boards. The 12-channel ADC reads back-EMF, current-sense amplifiers, and thermistor inputs while the UART streams telemetry to a host PLC or display. The 8 MHz instruction rate is sufficient for trapezoidal commutation at moderate RPM; the 50 I/O lines drive enable, direction, brake, and fault lines per axis. OTP memory prevents firmware tampering, which is valuable in OEM-locked motion-control modules.

Instrumentation and Front Panels
Front-panel instrumentation such as bench multimeters, laboratory data loggers, and process calibrators benefit from the PIC17LC752T-08I/L's 12-channel ADC for multi-range measurements and its UART for digital isolation links. The 68-pin PLCC package supports a generous key-matrix and 7-segment display interface without external I/O expanders. The PIC17 RISC core executes 8.25 MIPS, which is enough to run averaging filters and serial protocols without external DSP. The PLCC socket also simplifies calibration swap-out during service.
Được đề xuất
Embedded Networking Nodes
The PIC17LC752T-08I/L acts as the supervisory MCU in RS-485 or CAN-attached sensor nodes where it gathers analog data via the on-chip ADC and bridges to a host controller over UART or SPI. Its 678 bytes of RAM hold modest protocol stacks, and the I2C port drives a digital temperature sensor or RTC. The 50 GPIO pins also allow direct connection of LED indicators and user pushbuttons on the node enclosure. Industrial temperature grade and a robust 5 V CMOS core suit outdoor enclosure installations.
Được đề xuất
Point-of-Sale Terminals
In point-of-sale (POS) terminals and electronic cash registers, the PIC17LC752T-08I/L serves as the keyboard scanner, display driver, and serial concentrator. Its 50 GPIO lines drive a 10x10 key matrix, a character LCD, and magnetic-stripe reader LEDs. The UART connects to a printer, while the SPI port talks to a secure PIN-pad module. The OTP program memory prevents casual firmware cloning - an important property in payment terminals. Operating from 3.3 V or 5 V, the MCU drops directly into legacy POS power trees.
Được đề xuất
Legacy Printer and Display Controllers
Printers, label makers, and character displays used the PIC17LC752T-08I/L as a print-head driver and stepper controller. Its 50 GPIO lines carry phase currents for paper-feed steppers, head-enable lines, and sensor feedback (paper-out, cover-open). The 12-channel ADC monitors head temperature and supply current, and the UART accepts job data from the host. Because the PLCC is socketable, field servicing is straightforward: technicians can swap a programmed MCU in seconds.
Được đề xuất
Telecommunication Line Cards
The PIC17LC752T-08I/L appears in legacy telecommunication line cards and PBX backplanes as a supervisory controller. Its UART links to the central office framing equipment, its SPI bus drives codec configuration, and the 12-channel ADC monitors line voltage and loop current. Industrial temperature rating plus the 5 V tolerance of the LC variant make it suitable for controlled-environment telecom closets where reliable long-life operation matters more than cutting-edge CPU performance.

Ghi chú thiết kế
Allocate a 0.6-inch PLCC socket footprint for prototyping - the PIC17LC752T-08I/L uses 68 J-leads on 1.27 mm pitch across a 24.23 x 24.23 mm body. Keep the PLCC land pattern clear of vias to avoid solder wicking. Place a 0.1 uF ceramic decoupling capacitor on each VDD pin (there are multiple VDD pins on opposite sides of the package) within 3 mm of the package body to suppress switching transients from the 8 MHz oscillator.
The PIC17LC752T-08I/L operates from 2.5 V to 5.5 V; the lower bound is important for 3.3 V-only designs. At 8 MHz, the core draws roughly 10 mA active and 1 mA in sleep, so a low-ripple LDO such as the MCP1700 is sufficient for the VDD rail. Place a bulk 10 uF tantalum or ceramic capacitor near the PLCC plus a 0.1 uF bypass on each VDD pin to maintain ADC accuracy - the on-chip 12-channel 10-bit ADC is sensitive to VDD noise during conversions.
Do not confuse OTP memory with flash memory: the PIC17LC752T-08I/L can be programmed only once. Once the configuration bits are set and the program memory is written, the device cannot be erased or re-programmed. Design firmware with this constraint in mind - use a bootloader pattern in RAM only, and verify the entire code image in production test. Also note that the 'T' suffix denotes tape-and-reel, not a higher speed grade; the speed grade is encoded in the '08' suffix.
At 8 MHz with all peripherals active, the PIC17LC752T-08I/L dissipates roughly 50 mW into the PLCC package, which is well within the thermal envelope for industrial operation. The plastic PLCC body has a theta_JA of approximately 50 C/W, so a 50 mW dissipation yields only a 2.5 C junction rise - no heatsink is required. However, in a sealed enclosure with no airflow, derate ambient temperature by 5-10 C to account for self-heating.
