PIC16LC76-04I/SO - 8-bit 4MHz MCU 14KB OTP 28-SOIC | Microchip
MPN: PIC16LC76-04I/SO ✗ اختتامِ زندگیPIC16LC76-04I/SO جائزہ
An OTP (One-Time Programmable) microcontroller is a class of microcontroller whose program memory is implemented as one-time-writable EPROM cells rather than flash or ROM. Each bit cell can be programmed once using an external programming voltage (VPP), after which the firmware is non-volatile but cannot be rewritten. This construction delivers low unit cost for high-volume production, predictable in-circuit programming behavior, and excellent EMI robustness compared with flash parts of the same vintage, at the trade-off of no field re-programmability.
The PIC16LC76-04I/SO features integrated peripherals including a USART (SCI) port for asynchronous/synchronous serial communication, an MSSP module supporting both SPI and I2C master/slave modes, two 8-bit timer/counters with optional prescaler, a watchdog timer with on-chip RC oscillator, and an 8-channel 8-bit A/D converter with voltage reference. The device also includes power-saving SLEEP mode, low-power run mode, programmable code protection, and an industrial-grade operating temperature range of -40C to +85C.
Architecturally the PIC16C7X mid-range core uses a 14-bit wide instruction word with an 8-bit data bus, eight-level hardware stack, two-file register banks, and Harvard-style separate program/data paths. This design yields deterministic interrupt latency, a 2:1 instruction-to-clock ratio (Tcy = 4 Tosc) and a compact instruction set that compiles to efficient assembly-level code density, well-suited for embedded control loops.
Typical applications include industrial control systems, sensor signal conditioning front-ends, low-cost instrumentation, household appliance controllers, and embedded serial-bus peripherals. Engineers select this part when the application demands a 5V-tolerant 8-bit MCU with A/D conversion, a 28-SOIC footprint and BOM-cost optimization through OTP memory.
When designing with the PIC16LC76-04I/SO, confirm the firmware is finalized before programming because OTP memory cannot be erased and re-written. Ensure VPP programming voltage is sequenced correctly during in-circuit programming, and respect the maximum oscillator frequency rating at the supply voltage used to avoid clock-stretching or timing-margin violations.

PIC16LC76-04I/SO کے لیے موزوں ہے 6 ایپلیکیشنs: Industrial Control Systems, Sensor Signal Conditioning, Household Appliance Controllers, Low-Cost Instrumentation, Embedded Serial-Bus Peripherals, Automotive Cabin Electronics (Non-Safety).
Industrial Control Systems
The PIC16LC76-04I/SO fits industrial control panels because its -40C to +85C industrial temperature rating tolerates factory-floor thermal stress, and its 8-channel 8-bit ADC digitizes sensor inputs (temperature, pressure, flow) at typical 5V analog signal levels. The 22 I/O pins drive relay coils, optocouplers and LED indicators, while the MSSP/I2C peripheral talks to EEPROMs and digital potentiometers. With OTP memory, production-line programming is fast and the BOM stays low compared with flash PICs, and the 28-SOIC footprint drops into thousands of proven reference designs.

Sensor Signal Conditioning
Front-end sensor conditioning benefits from PIC16LC76-04I/SO's integrated 8-bit ADC and 22 I/O pins: analog sensor outputs are sampled directly, then digitally filtered in firmware before transmission via USART. The mid-range core's deterministic 1 us instruction cycle makes closed-loop PID control feasible at kHz rates, and OTP memory guarantees a known firmware image that never drifts in the field. Industrial -40C to +85C support lets the same board deploy in outdoor or cold-storage installations.

Household Appliance Controllers
Washing-machine, dishwasher and microwave controllers use the PIC16LC76-04I/SO because OTP memory locks the firmware, satisfying regulatory approvals that mandate identical firmware across production lots. The 4 MHz instruction rate runs user-interface scanning, motor-control PWM via timer interrupts, and USART status reporting to a master display board. The 28-SOIC package handles conformal coating for humid environments and reflows cleanly on lead-free lines.

Low-Cost Instrumentation
Handheld DMMs, tachometers and bench instruments rely on PIC16LC76-04I/SO's 8-bit ADC, USART and the same 5V supply rails commonly present in test gear. The 14 KB OTP program memory fits state-machine UI code plus calibration tables in EPROM, while the 22 I/O drive LCD segment lines and key-matrix scanning. Designers appreciate the deterministic interrupt latency when timing ADC sampling windows for accurate RMS calculations.

Embedded Serial-Bus Peripherals
The MSSP (SPI/I2C) peripheral on the PIC16LC76-04I/SO lets the MCU operate as a master on I2C sensor buses or as a SPI slave to a host processor, making it ideal for adding field-replaceable I/O expanders, lighting or motor-driver front-ends. The OTP memory locks the protocol stack so the peripheral presents a stable register map. Industrial-temp qualification and 5V tolerance match legacy 5V fieldbus hardware.
تجویز کردہ
Automotive Cabin Electronics (Non-Safety)
The PIC16LC76-04I/SO serves non-safety cabin modules such as HVAC controllers, seat-position memories and auxiliary lighting where -40C to +85C covers cabin conditions. OTP memory locks the calibration tables against accidental firmware corruption, and the 8-channel ADC reads thermistor and potentiometer inputs. Note that AEC-Q100 is not qualified; for safety-relevant ECUs, designers should pick AEC-Q100 listed parts such as PIC16F876A-I/SO or dsPIC variants.

ڈیزائن نوٹس
Estimated: PIC16LC76-04I/SO OTP memory cannot be erased after programming. Always validate firmware on a flash twin (e.g. PIC16F876-04I/SO) before committing to the OTP part so a final bug does not scrap the lot. Per Microchip PIC16C7X datasheet family, programming requires VPP on the MCLR/VPP pin during high-voltage programming mode; missing or out-of-spec VPP yields programmer errors that mimic dead silicon. Verify programmer socket pinout matches the 28-SOIC package before mass-programming.
Estimated: At VDD = 5V and all peripherals active, PIC16LC76-04I/SO draws roughly 5 mA to 10 mA depending on oscillator mode and ADC duty cycle. Use a bulk decoupling capacitor of at least 10 uF plus a 100 nF ceramic on VDD within 5 mm of the IC to suppress switching transients from the internal charge-pump that drives OTP programming. Brown-out detector settings should be configured to match the lowest expected VDD in the application.
For the 28-SOIC (0.295", 7.50 mm) footprint, route VDD and VSS traces wider than 0.2 mm to limit DC drop, and place the bulk capacitor within 5 mm of the VDD/VSS pins. The MCLR/VPP pin is sensitive to fast edges; place a 100 nF + 10 kohm reset network close to the pin to avoid spurious resets during in-circuit programming. The 28-SOIC body is wide enough to allow standard SOIC test clips, but production panels should avoid hand-soldering to keep lead-free reflow profiles uniform.
The MSSP (SPI/I2C) and USART pins (RC3-RC7) should be routed as short matched-length traces with series damping resistors near the MCU when the bus is longer than 50 mm. Keep analog RA0-RA5 traces away from the digital RC bus to preserve ADC accuracy; the 8-bit ADC has limited rejection of digital switching noise. For OTP programming, route MCLR/VPP away from RC traces so the high-voltage programming pulse does not couple into adjacent I/O.
