PIC17LC752-08I/PT - 8-Bit 8MHz CMOS EPROM MCU, 16KB | Microchip
MPN: PIC17LC752-08I/PT ✓ AktifPIC17LC752-08I/PT Ringkasan
A microcontroller (MCU) is a single-chip computer containing a CPU, non-volatile program memory (ROM/Flash/OTP), volatile data memory (RAM), and a configurable set of peripherals such as timers, A/D converters, communication ports, and interrupt controllers. Within the broader semiconductor taxonomy, the PIC17LC752 belongs to the 8-bit MCU -> microcontroller -> embedded processor -> semiconductor hierarchy. The PIC17 family specifically targets higher pin-count, higher-performance 8-bit applications that require more peripherals and I/O than the baseline PIC16 family can offer.
Key features include a 10-bit A/D converter with up to 12 channels, dual capture/compare/PWM modules, a USART port, an SSP port supporting SPI and I2C, hardware multiplication, and a flexible interrupt controller with vectored interrupts. The OTP program memory is one-time programmable, making this part well suited to mature, high-volume production where field firmware updates are not required. The wide 2.5 V to 5.5 V supply range allows operation from regulated 3.3 V rails or directly from a 5 V system bus.
Typical applications include industrial control front-ends, HVAC and appliance controllers, motor control peripheral boards, instrumentation front panels, and embedded sensor hubs where deterministic real-time response matters. The 121 ns single-cycle instruction execution provides predictable interrupt latency that simplifies firmware timing analysis in safety-related control loops.
When designing with this device, ensure the EPROM programming window is correctly handled in production programming equipment and that brown-out and watchdog timer settings are tuned to the application. The industrial (-40C to +85C) temperature grade and the legacy PDIP package make the PIC17LC752-08I/PT primarily suited to through-hole industrial designs.

Aplikasi Umum
PIC17LC752-08I/PT cocok untuk 6 aplikasis: Industrial Control Front-End, HVAC and Appliance Controller, Motor Control Peripheral Board, Instrumentation Front Panel, Embedded Sensor Hub, Security and Access Control Panel.
Industrial Control Front-End
The PIC17LC752-08I/PT's 8 MIPS throughput, 33 I/O lines, and integrated 10-bit A/D converter make it well suited to industrial control front-end boards where deterministic real-time response is critical. The 121 ns instruction cycle provides predictable interrupt latency, simplifying firmware timing analysis in safety-related control loops. Operating from a 2.5 V to 5.5 V rail allows direct connection to common 24 V-buck-derived 5 V or 3.3 V industrial power supplies without additional level shifters. The wide -40C to +85C industrial temperature grade handles factory floor thermal stress.

HVAC and Appliance Controller
The PIC17LC752-08I/PT is well matched to HVAC and appliance controllers where multiple sensors, triac drivers, and user interfaces must be coordinated. The 10-bit ADC handles thermistor and pressure-sensor inputs, while the 33 I/O lines drive relay coils, TRIAC optocouplers, and display multiplexers. The OTP EPROM memory is sufficient for fixed-function firmware that does not require field updates, lowering per-unit cost in volume appliance production.

Motor Control Peripheral Board
The PIC17LC752-08I/PT's Capture/Compare/PWM modules and high-throughput core suit brushed DC and stepper motor peripheral boards. PWM channels drive H-bridge MOSFET gates while the ADC samples current-sense amplifiers for closed-loop torque control. The 8 MIPS performance ensures PWM loops execute without jitter, and the wide supply range simplifies integration with 5 V gate driver supplies typical in industrial motor drives.

Instrumentation Front Panel
The PIC17LC752-08I/PT drives front-panel keypads, LCD or VFD displays, and rotary encoders on bench-top instruments. Its 33 I/O lines handle matrix keypads and parallel display interfaces, while the USART connects to main DSP or FPGA signal-processing boards. The 10-bit ADC reads front-panel potentiometers and analog reference voltages, and the 2.5 V to 5.5 V range accommodates instrumentation-grade power rails.

Embedded Sensor Hub
The PIC17LC752-08I/PT acts as a sensor hub aggregating I2C and SPI sensor data and forwarding it over USART to a host controller. The integrated SSP port supports both SPI and I2C masters, enabling direct connection to accelerometers, temperature sensors, and EEPROMs without glue logic. The 678-byte RAM buffers sensor frames, and the deterministic instruction cycle preserves sensor timing integrity.

Security and Access Control Panel
The PIC17LC752-08I/PT handles keypad entry, RFID reader interfaces, and alarm loop monitoring in access control panels. Its 33 I/O lines drive relay outputs for door strikes, read magnetic contact inputs, and interface to Wiegand-format card readers. OTP EPROM prevents firmware tampering, and the industrial temperature grade ensures reliability in unheated entry vestibules and outdoor enclosures.

Catatan Desain
Decouple VDD with a 100 nF ceramic capacitor placed within 5 mm of each VDD pin (pins 11 and 40) and add a bulk 10 uF tantalum or aluminum polymer capacitor at the board entry point. The PIC17LC752 has dual VDD/VSS pin pairs to reduce digital switching noise injection into analog sections. Keep the analog VDD/VSS pair and digital VDD/VSS pair star-grounded at a single point near the MCU to preserve A/D converter accuracy.
Route the OSC1/OSC2 crystal traces as short, symmetric loops with the load capacitors placed close to the MCU. For 33 MHz operation, use a fundamental-mode crystal with ESR under 60 ohm. Keep high-current switching traces (TRIAC gate drives, relay coils) routed away from the analog input pins (AN0-AN8) to minimize ADC sampling crosstalk.
Do not apply MCLR/VPP (pin 9) above VDD + 0.3 V during normal operation - this pin is used for in-circuit programming and can damage the part if driven by an external logic signal accidentally. Always include a 10 kohm pull-up on MCLR and a 100 nF decoupling cap to VDD at the MCLR pin. Also ensure brown-out reset is enabled in the configuration word to prevent undefined execution at low VDD.
Estimated: at maximum CPU activity (8 MIPS, VDD = 5.5 V), power dissipation is approximately 30-50 mW, well within the PDIP-40 package's thermal limit. Junction temperature rise above ambient is roughly 5 C/W x 0.05 W = 0.25 C, negligible. No heatsink or thermal management is required for normal operation even in sealed enclosures at +85C ambient.
