PIC16LF1516-E/SS Présentation
An 8-bit microcontroller is a single-chip computer built around a data bus and ALU eight bits wide, paired with on-chip Flash, RAM, and peripherals. It sits inside the hierarchy of microcontrollers -> MCUs -> embedded processors -> semiconductors. The 'F' in PIC16F denotes Flash program memory, the 'L' denotes a low-power (LF) variant rated 1.8 V to 3.6 V, and the 'XLP' label marks Microchip's eXtreme Low Power technology for sleep currents in the nanoampere range - making this part suitable for battery-powered IoT and energy-harvesting products.
Key features include a 20 MHz maximum operating frequency, 14 KB self-read/write Flash (IEC 60730 Class B support), 10-bit A/D converter with selectable references, an internal 16 MHz oscillator, and support for I2C, SPI, and USART (MI2C/SPI/EUSART) peripherals. The 28-SSOP package provides a compact 0.65 mm pitch, 5.30 mm body footprint suited to hand-soldered prototypes and high-density commercial boards.
The PIC16LF1516-E/SS uses Microchip's enhanced mid-range core with 49 instructions and a 16-level hardware stack, providing deterministic real-time response and C-friendly code density. The XLP technology combined with nanoWatt XLP sleep modes delivers typical sleep currents below 1 µA, enabling years of operation from coin-cell batteries in duty-cycled sensor nodes.
Typical applications include consumer electronics control boards, IoT sensor nodes, low-power remote controls, white goods user interfaces, and battery-powered industrial sensor transmitters. The wide peripheral set and ample Flash make it a strong fit for products that need more code space than a PIC10/12/16F1xxx entry-level MCU but do not require a 16-bit dsPIC® or 32-bit ARM Cortex-M device.
When designing with this device, ensure the chosen supervisor and decoupling network matches the 1.8 V to 3.6 V VDD range. For power-critical designs, leverage the XLP sleep modes and clock-gated peripherals; for code-density-critical designs, allocate at least 1 KB of Flash headroom for the ICD debug library and bootloader.

Applications typiques
PIC16LF1516-E/SS convient pour 6 applications: Battery-Powered IoT Sensor Node, Consumer Remote Control, White Goods User Interface, Industrial Sensor Transmitter, Hobby / Maker Project Controller, LED Lighting Controller.
Battery-Powered IoT Sensor Node
The PIC16LF1516-E/SS fits battery-powered IoT sensor nodes because its 1.8-3.6 V VDD range lets it run directly from a single Li-ion cell down to deep discharge, and its XLP nanoWatt technology delivers sleep currents below 1 µA typical. The 14 KB Flash supports BLE/Zigbee command firmware plus application code, while the 10-bit ADC reads analog sensor outputs (temperature, light, gas). Placed on a 3.3 V coin-cell board with duty-cycled wake every 10 seconds, it can extend battery life to 2+ years on a single CR2477 cell.
Recommandé
Consumer Remote Control
The PIC16LF1516-E/SS suits consumer remote controls because its 20 MHz core runs IR protocol stacks (NEC, RC5, Sony SIRC) with margin to spare, and its 14 KB Flash holds multi-protocol firmware plus custom button mappings. The MI2C peripheral drives OLED displays or I/O expanders for smart-TV remotes, while the 1.8-3.6 V VDD lets it run on 2x AAA cells without boost regulation. Compared with discrete logic ICs, the integrated MCU reduces BOM cost and PCB area.
Recommandé
White Goods User Interface
The PIC16LF1516-E/SS powers washing machine, dishwasher, and refrigerator user interfaces because its 14 KB Flash holds state-machine logic, LCD/keypad drivers, and diagnostic routines. The 10-bit ADC reads rotary encoder or potentiometer inputs, while the EUSART communicates with the main appliance controller board. The wide -40 °C to +125 °C operating range covers appliance interior temperatures, and the 28-SSOP package is hand-solderable for low-volume appliance production.
Recommandé
Industrial Sensor Transmitter
The PIC16LF1516-E/SS drives 4-20 mA industrial sensor transmitters because its 1.8-3.6 V VDD enables loop-powered operation from a 24 V rail with linear regulation, and its enhanced mid-range core executes calibration and linearization algorithms in real time. The 10-bit ADC provides 0.1% typical INL for pressure and temperature transmitters, while SPI connects to external 16/24-bit sigma-delta ADCs for higher-precision measurements. Industrial -40 °C to +125 °C rating ensures field-deployed reliability.
Recommandé
Hobby / Maker Project Controller
The PIC16LF1516-E/SS fits hobby and maker projects because it is supported by MPLAB X IDE, XC8 compiler (free), and the PICkit programmer ecosystem. Its 14 KB Flash holds Arduino-style sketches ported to PIC, while 512 bytes RAM is sufficient for sensor-fusion prototypes. The 28-SSOP package fits standard 0.65 mm-pitch breakout boards and breadboard adapters. Compared with ATmega328P, the PIC16LF1516 offers lower power and a smaller footprint at similar cost.
Recommandé
LED Lighting Controller
The PIC16LF1516-E/SS controls decorative and architectural LED lighting because its 14 KB Flash stores DMX-512, DALI, or proprietary lighting protocols, and its PWM-capable CCP peripherals drive LED MOSFET drivers directly. The MI2C peripheral reads ambient light sensors for daylight harvesting, while the 1.8-3.6 V VDD range simplifies power supply design for 3.3 V LED driver rails. Compared with dedicated LED controllers, the programmable MCU enables custom dimming curves and color-mixing algorithms.

Principaux différenciateurs
- Lowest minimum VDD in 14 KB Flash 28-SSOP PIC16 family (vs PIC16F1516-E/SS)
- Double the Flash versus PIC16LF1508 in same footprint (vs PIC16LF1508-E/SS)
- XLP nanoWatt sleep technology vs older non-LF family (vs PIC16F1516-E/SS)
Notes de conception
Decouple VDD (pin 8 and pin 20 VSS) with a 100 nF ceramic capacitor placed within 3 mm of the IC, plus a bulk 10 µF tantalum or aluminum-polymer capacitor near the regulator. The PIC16LF1516-E/SS draws microamp-level current in sleep; bypass capacitors must have low leakage (X7R or X5R dielectric) to avoid dominating the sleep budget. For battery-powered designs, choose a low-Iq LDO such as MCP1700 (1.6 µA quiescent) to maximize standby life.
The PIC16LF1516-E/SS SSOP-28 package has a theta_JA of approximately 95 °C/W, which is acceptable for typical MCU workloads because active current at 20 MHz / 3.3 V is below 10 mA - power dissipation stays well under 50 mW. No heatsink is required. Estimated: at VDD=3.3 V, IDD active 20 MHz = ~5 mA => Pdiss = 16.5 mW => junction rise above 25 °C ambient = 1.6 °C. Designers in sealed enclosures above 70 °C ambient should validate with a thermal probe.
Do NOT apply 5 V VDD to the PIC16LF1516-E/SS - the LF variant has an absolute maximum VDD of 3.6 V (the datasheet rating). Use PIC16F1516-E/SS instead for 5 V rails. Also, ensure /MCLR (pin 1) is either tied to VDD through a 10 kΩ pull-up or left as a reset input - never left floating, as noise on /MCLR will cause unintended resets. For ICD debugging, route ICSPDAT and ICSPCLK to a 6-pin header with 4.7 kΩ pull-downs on the data line.
Route the 20 MHz internal oscillator traces (RA6/OSC2, RA7/OSC1) with minimal trace length and ground shielding. Even though the PIC16LF1516 uses the internal 16 MHz HFINTOSC by default, exposing RA6/RA7 to noisy digital traces can couple noise into the oscillator. For PCB layout, place the MCU at least 5 mm away from switching power inductors, and use a ground pour on the top layer stitched with vias to the bottom ground plane.
