PIC16LF76T-I/SS - 8-Bit 20MHz 14KB Flash MCU 28-SSOP | Microchip
MPN: PIC16LF76T-I/SS ✓ فعالPIC16LF76T-I/SS جائزہ
An 8-bit microcontroller (often abbreviated MCU) is a single-chip computer that integrates a CPU, RAM, non-volatile program memory, and peripheral I/O on one die. The PIC16 family from Microchip uses a Harvard-architecture RISC instruction set with only 35 single-word instructions, positioned between simpler PIC10/12 devices and the higher-pin-count PIC18 series. The 'LF' prefix denotes an extended Vdd range down to 2.0 V, enabling battery-powered designs where standard 'F' parts cannot operate.
Key features of the PIC16LF76T-I/SS include the enhanced CCP (Capture/Compare/PWM) module, a USART with LIN support, an MSSP peripheral configurable for SPI or I2C (master/slave), two 8-bit timers plus one 16-bit timer, and a 10-bit PWM generator. An integrated BOR (Brown-Out Reset) and Power-on Reset improve field reliability, while nanoWatt-style SLEEP modes drop quiescent current below typical watchdog operation levels - critical for battery-backed or energy-harvesting designs.
Typical applications include industrial control panels, sensor-interface boards, automotive body and accessory ECUs (where the wider Vdd range provides noise margin), appliance front-panel controllers, lighting ballast control, and low-cost remote sensor nodes. The 28-SSOP footprint is friendly to hand-rework and double-sided hobby boards while still offering enough I/O for a full keypad + display + UART bridge.
When designing with this MCU, derate the 20 MHz maximum speed linearly with voltage below 4.0 V (4 MHz spec at 2.0 V). Use the on-chip ADC with a 5 MHz / Vdd conversion budget and add an external op-amp buffer for high-impedance sensors. This page synthesizes distributor pricing, validated drop-in alternatives, and practical design notes that complement the Microchip datasheet.

عام استعمالات
PIC16LF76T-I/SS کے لیے موزوں ہے 6 ایپلیکیشنs: Industrial Control Panels, Sensor Interface Boards, Automotive Body and Accessory ECUs, Appliance Front-Panel Controllers, Lighting Ballast and LED Driver Control, Low-Cost Remote Sensor Nodes.
Industrial Control Panels
The PIC16LF76T-I/SS fits industrial control panels because its 22 digital I/O lines can directly drive 4x4 keypads, 7-segment multiplexed displays, and relay banks without external glue logic. The 2.0-5.5 V Vdd range allows the same BOM to be used on 24 V-buck-derived 5 V and 3.3 V logic boards, and the USART bridges to RS-485 transceivers for Modbus RTU links. With 14 KB Flash and 368-byte SRAM, the MCU runs state-machine control firmware with room for keypad debouncing, fault logs, and menu handlers, while the integrated BOR/POR ensures clean reset behavior in electrically noisy cabinet environments.

Sensor Interface Boards
The PIC16LF76T-I/SS serves sensor-interface boards because the 5-channel 8-bit ADC samples thermistor, photocell, and 4-20 mA loop signals at modest resolutions while the MSSP peripheral streams results over SPI or I2C to a host processor. Its 20 MHz CPU supports up to 5 MIPS of DSP-light filtering (moving average, Kalman-lite), and the wide 2.0 V Vdd floor lets the same firmware target battery-powered wireless sensor nodes and line-powered industrial transmitters. NanoWatt SLEEP keeps standby current below data sheet watchdog levels for energy-harvesting or duty-cycled designs.

Automotive Body and Accessory ECUs
The PIC16LF76T-I/SS is used in low-speed automotive body controllers - window regulators, mirror adjusters, seat-position memory modules - because its 2.0-5.5 V Vdd tolerates cranking transients and 12 V-rail dropouts when powered from regulated 5 V rails. Its 22 I/O drive small relay coils and H-bridge MOSFETs directly through gate drivers, while the USART supports LIN bus communication for body-domain networking. Note this part is industrial-grade (-40C to +85C) rather than AEC-Q100 qualified; for under-hood or safety-relevant ECUs choose PIC16F15344 or PIC18F family members instead.

Appliance Front-Panel Controllers
The PIC16LF76T-I/SS runs washing machine, dishwasher, and microwave front-panel boards where it reads capacitive touch keys, multiplexes 7-segment or TFT displays, and toggles triac-driven loads. Its 20 MHz throughput drives PWM dimming for LED indicators and supports USART link to a main appliance controller for diagnostics. The wide Vdd range accepts the rectified-and-regulated 5 V rails common in white-goods, and the BOR ensures orderly recovery from brown-out events during power-line glitches.

Lighting Ballast and LED Driver Control
The PIC16LF76T-I/SS works as the digital ballast brain in fluorescent and HID ballasts, and as a digital LED driver controller in commercial lighting fixtures. Its 10-bit PWM module dims LEDs with smooth 1024-step resolution, and the 5-channel ADC monitors current-sense shunts for closed-loop brightness regulation. The PIC16 instruction set executes deterministic interrupt-driven control loops at well-defined cycle counts, important for power-factor-correction (PFC) firmware and DMX-512 dimming decoders in architectural lighting.
تجویز کردہ
Low-Cost Remote Sensor Nodes
The PIC16LF76T-I/SS powers low-cost remote sensor nodes because its 2.0 V Vdd floor accepts 2x AA cells, the nanoWatt SLEEP modes stretch battery life into multi-year ranges, and the MSSP links to sub-GHz or BLE modules for wireless reporting. Its 14 KB Flash supports sensor fusion, encryption helpers, and OTA-ready bootloader stubs, while the small 28-SSOP footprint keeps the PCB under 25 mm x 25 mm. Industrial temperature grade suits outdoor enclosures in climates with seasonal extremes.

ڈیزائن نوٹس
Estimated: at 20 MHz CPU clock and Vdd = 5.0 V, the PIC16LF76T-I/SS typical operating current is approximately 10-15 mA (datasheet DC characteristic, IIDD vs frequency). For battery-powered designs running at 32 kHz LP oscillator and SLEEP between interrupts, total average current drops to microamps. Decouple Vdd/Vss pairs (pin 8/20) with 100 nF ceramic placed within 5 mm of the MCU pins to suppress switching noise on the supply rail.
Route the ICSP signals (MCLR/Vpp pin 1, RB6/PGC pin 27, RB7/PGD pin 28) to a dedicated 6-pin programming header with no series resistors in-line. Keep the header at the board edge so the PICKit or ICD can clip on without removing the device. Add a 10 kohm pull-up on MCLR and a 100 ohm series resistor on PGC/PGD to suppress programming-port noise during normal operation.
Do not exceed 25 mA source/sink per I/O pin or 200 mA total across PORTA + PORTB + PORTC; banked PIC16 parts have independent 100 mA Vdd/Vss budgets per port pair. Always de-bounce mechanical inputs in firmware or with an RC filter because PIC16 interrupt-on-change triggers on rising AND falling edges. For 3.3 V designs, ensure your programmer supports the LF Vdd range or supplies 5 V to Vpp for proper ICSP high-voltage programming.
The PIC16LF76T-I/SS digital I/O edges at approximately 5 ns at 20 MHz; place any analog-input traces (AN0-AN4 on PORTA) at least 2 trace widths away from clock lines such as OSC1/OSC2 or PGC to minimize ADC crosstalk. Use a ground guard ring around the analog Vref pin (RA3) when reading high-impedance sensors; tie unused analog pins to Vdd to keep the input mux in a defined state.
