PIC16LF15356T-I/MV Descripción general
An 8-bit PIC microcontroller is a RISC-based (Reduced Instruction Set Computer) embedded controller that executes one instruction per clock cycle (except branches), enabling deterministic real-time performance at low power. PIC MCUs sit within the broader hierarchy: 8-bit microcontroller -> microcontroller -> embedded controller -> semiconductor IC. The PIC16F153xx family specifically targets battery-powered and energy-harvesting designs where nanoWatt XLP sleep currents, peripheral activity monitoring, and flexible oscillator selection are essential. The 'LF' prefix denotes the wide 1.8V-3.6V VDD range optimized for single-cell Li-coin or 2xAA alkaline battery chemistries, while the 'T' suffix indicates tape-and-reel packaging for high-volume SMT assembly.
Key differentiating features of the PIC16LF15356 include its 28KB Flash (double the 14KB of the lower-end PIC16LF15325/15344 siblings), 256 bytes of data EEPROM for non-volatile user parameter storage, four independent 16-bit PWM channels with complementary outputs, and the CWG peripheral which simplifies Class-D audio, motor drive, and switched-mode power topologies. The four CLC blocks allow logic function synthesis in hardware, offloading the CPU and reducing firmware complexity.
Typical applications include IoT sensor nodes, low-power wireless modules, battery-powered home automation devices, white-goods and small appliance controllers, LED lighting controllers, and portable medical/wellness devices. The combination of 25 I/O, 12-bit ADC, and rich communication peripherals also makes it well suited for human-machine interface (HMI) controllers and motor-control daughter cards. Industrial 4-20mA sensor transmitters benefit from the wide operating voltage and integrated 5-bit DAC.
When designing with this part, ensure the VDD rail is decoupled with a 100 nF X7R ceramic capacitor within 5 mm of the VDD pin and a bulk 1 µF-10 µF capacitor on the same net. The 32 MHz internal oscillator eliminates the need for an external crystal in most applications; if crystal accuracy is required, route the crystal traces with short, symmetric lengths and a guard ring tied to ground.

Aplicaciones típicas
PIC16LF15356T-I/MV es adecuado para 7 aplicacións: Battery-Powered IoT Sensor Nodes, Home Appliance Control Boards, LED Lighting Controllers, Portable Medical and Wellness Devices, Wireless Module Companion MCU, Industrial 4-20 mA Sensor Transmitters, Human-Machine Interface (HMI) Controllers.
Battery-Powered IoT Sensor Nodes
The PIC16LF15356T-I/MV fits battery-powered IoT sensor nodes because of its 1.8V-3.6V VDD range (compatible with 1x Li-coin and 2xAA chemistries) and the PIC XLP nanoWatt technology that drops Sleep current to the 30-100 nA range with RTCC running. The four CLC blocks let the MCU trigger sensor sampling autonomously without waking the CPU, while the 10-bit ADC with 25 input channels handles multi-sensor front-ends directly. Its 28 KB Flash is enough for MODBUS/RTU stacks plus sensor fusion code, and the UQFN-28 (4x4 mm) footprint suits sub-10 mm sensor modules.
Recomendado
Home Appliance Control Boards
The PIC16LF15356T-I/MV suits home appliance controllers (coffee makers, air purifiers, washing machine HMIs) thanks to its four 16-bit PWMs (driving LED indicators, buzzer tones, and small DC fans), 25 I/O for keypad/switch matrices, and the CWG peripheral that simplifies zero-cross TRIAC dimming. The 32 MHz core delivers deterministic interrupt response for safety-critical timing, and the 2 KB RAM comfortably hosts UI state machines plus a small RTOS. The UQFN-28 (4x4) footprint saves PCB area versus SOIC-28, ideal for compact appliance boards.
Recomendado
LED Lighting Controllers
The PIC16LF15356T-I/MV is well matched to constant-current LED drivers and RGBW lighting controllers because its Complementary Waveform Generator (CWG) generates complementary PWM pairs with programmable dead-band, ideal for synchronous buck/boost LED driver topologies. The 5-bit DAC provides logarithmic dimming curves, and four 16-bit PWMs allow smooth color mixing across multiple LED strings. Its 1.8V minimum VDD lets a single-cell Li-ion battery power wireless DMX or BLE-controlled fixtures, while the 32 MHz core supports the DALI or Casambi protocols in real time.
Recomendado
Portable Medical and Wellness Devices
The PIC16LF15356T-I/MV fits portable medical and wellness devices (glucometers, pulse oximeters, fitness wearables) thanks to its XLP Sleep currents in the 30-100 nA range that extend coin-cell battery life beyond a year. The 10-bit ADC combined with two on-chip comparators can directly measure analog front-ends for optical heart-rate or temperature sensors, while the CLC blocks offload pulse-rate detection logic from the CPU, reducing firmware overhead. Its wide 1.8-3.6V VDD range is compatible with single-cell Li-coin chemistries commonly used in medical wearables.
Recomendado
Wireless Module Companion MCU
The PIC16LF15356T-I/MV is often paired as a host MCU alongside Wi-Fi, BLE, or LoRa modules, where its two EUSART peripherals and MSSP (SPI/I2C) provide multiple simultaneous communication channels. The 32 MHz core runs AT-command parsing or lightweight TCP/IP stacks for sub-MCU Wi-Fi coprocessors like the ATWINC1500. With 28 KB Flash, ample code space remains for application logic, secure boot, and OTA update stubs. The UQFN-28 (4x4) keeps the total module footprint under 15x20 mm, ideal for space-constrained wireless designs.
Recomendado
Industrial 4-20 mA Sensor Transmitters
The PIC16LF15356T-I/MV is well suited for loop-powered 4-20 mA industrial sensor transmitters, where its 1.8V minimum VDD extends operation at low loop currents (below 3.5 mA) when used with an external LDO. The two comparators and 5-bit DAC enable low-side current setting with PWM-LPF output, while the 10-bit ADC reads the 1.25V-5V compliance voltage and ratiometric sensor bridges. The CWG peripheral simplifies HART modem carrier generation when paired with an external HART modem IC, and the industrial -40°C to +85°C rating covers most process-control environments.
Recomendado
Human-Machine Interface (HMI) Controllers
The PIC16LF15356T-I/MV drives small HMI boards (keypads, LCD character displays, encoder inputs) thanks to 25 I/O that easily handle 4x4 matrix keypads plus a 16x2 LCD or OLED, with the 2 KB RAM hosting UI state machines and debounce buffers. The four 16-bit PWMs generate backlight dimming and buzzer tones, while the CLC blocks implement hardware debouncing and quadrature decoding without CPU load. Its UQFN-28 (4x4 mm) footprint suits slim HMI daughter cards behind glass or membrane panels.

Notas de diseño
Place a 100 nF X7R ceramic decoupling capacitor within 5 mm of each VDD pin and a bulk 1 µF-10 µF capacitor on the same VDD net. For battery applications drawing <2 mA peak, an MCP1700 3.3V LDO provides a clean rail with only 1.6 µA quiescent current. If the design uses Sleep currents below 1 µA, choose a low-Iq buck regulator such as the MCP16411 to maximize runtime. The PIC16LF15356 VDD ramp must be monotonic for proper brown-out reset; avoid RC time constants above 100 ms on VDD.
The 28-pin UQFN (4x4 mm) package has a center thermal/exposed pad that must be soldered to a 2.5x2.5 mm copper pour on the top layer. The center pad improves thermal dissipation; it is NOT internally connected to VSS or VDD. Connect the center pad to the ground plane through 4-9 thermal vias (0.3 mm drill, 0.6 mm pitch) to reduce ground impedance. Keep traces under the UQFN package at least 0.2 mm clearance from the pad edge to prevent solder wicking defects.
Do not exceed 3.6V on any pin; the PIC16LF15356 is NOT 5V tolerant. The MCLR pin has an internal pull-up but adding a 10 kΩ external pull-up and a 100 nF decoupling capacitor prevents spurious resets in noisy environments. The internal 32 MHz HFINTOSC has ±2% accuracy at 3.3V/25°C; if your design requires USB or accurate UART timing, use an external 16MHz crystal on OSC1/OSC2 with 15-33 pF load capacitors placed within 5 mm of the pins.
Route the ICSPDAT and ICSPCLK traces (RB6/RB7) close together with ground guard traces to maintain signal integrity during programming. Analog inputs (RA0-RA3, RB1-RB5) should be routed away from digital switching traces; place a ground ring around sensitive analog traces. The complementary PWM channels (PWM3/PWM4 with CWG) require symmetric trace lengths of <25 mm between MCU pins and the gate driver to minimize dead-band mismatch.
