PIC16LF15354-E/ML Overview
An MCU (Microcontroller Unit) is a single-chip computer that integrates a CPU, non-volatile program memory, working RAM, and configurable peripherals such as timers, ADC, communication interfaces and I/O. The PIC16LF15354 sits in Microchip's PIC16 XLP family - a low-power 8-bit line positioned between simple PIC10/12 parts and higher-end PIC18/dsPIC devices. Its product type hypernyms are: MCU -> microcontroller -> 8-bit microcontroller -> embedded controller -> semiconductor. The XLP (eXtreme Low Power) designation reflects deep-sleep currents in the nA range and fast wake-up times, which is the key differentiator versus older PIC16F parts.
Key features include four 10-bit PWM outputs, a hardware comparator, a 5-bit/10-bit DAC, a 10-bit ADC with up to 25 analog channels, a Complementary Waveform Generator (CWG), four Configurable Logic Cells (CLC), two EUSART peripherals, plus MSSP-based SPI and I2C. The device also integrates a Numerically Controlled Oscillator (NCO), zero-cross detection, and on-chip debug support via MPLAB ICD. These Core Independent Peripherals (CIPs) allow many control tasks to run without CPU intervention, further reducing average power.
Internally, the PIC16LF15354 uses a 14-bit instruction word modified Harvard architecture with a 32kHz to 32MHz internal oscillator, allowing software-selectable clock sources between INTOSC and an external crystal. The 28-QFN package exposes 25 I/O pins with high-current sink/source capability, programmable weak pull-ups, interrupt-on-change, and peripheral pin select (PPS) remapping for flexible PCB routing.
Typical applications include low-power IoT sensor nodes, e-Locks, touch/proximity user interfaces, white-goods and small appliance control, and battery-powered metering. Designers select the PIC16LF15354-E/ML when energy budget and BOM cost dominate over raw CPU throughput.
When designing with this part, use MPLAB X IDE plus the XC8 compiler; place a 0.1uF decoupling capacitor within 3mm of every VDD pin and provide a bulk capacitor on the input rail. Always configure the PPS registers before assigning peripheral signals to physical pins.

Typical Applications
PIC16LF15354-E/ML is suitable for 7 applications: Battery-Powered IoT Sensor Nodes, Electronic Locks and Access Control, Small Appliance and White-Goods Control, Touch/Proximity and HMI Front-Ends, Industrial Sensor Transmitters and Metering, Remote Control and Smart-Home Peripherals, Automotive Interior Sub-Modules (Non-Safety).
Battery-Powered IoT Sensor Nodes
The PIC16LF15354-E/ML fits battery-powered IoT sensor nodes where sleep current dominates battery life. Its XLP silicon idles in the nA range and wakes in microseconds, while the 1.8V-3.6V VDD range runs directly from a Li-coin or 2xAA cells without a boost converter. With four CLCs the device can scan a sensor autonomously, drive the CWG, and only wake the CPU when the threshold trips. This combination can extend a CR2032 node lifetime from a few months into several years, beating older PIC16F1xx designs.
Recommended
Electronic Locks and Access Control
For electronic locks the PIC16LF15354-E/ML delivers deterministic response time at 32 MHz, hardware PWM for haptic/motor feedback, and a comparator for tamper-line monitoring without waking the CPU. The 7 KB Flash fits encryption handshake state machines plus fault logging, while 224 bytes EEPROM stores calibration constants across lockouts. The 28-QFN package keeps the PCB footprint under 36 mm^2, important for inline deadbolt modules. Drop-in compatibility with PIC16F15354 means 5V-tolerant variants can be qualified on the same layout.
Recommended
Small Appliance and White-Goods Control
In a washing machine, dishwasher or induction cooktop front-end, the PIC16LF15354-E/ML brings four 10-bit PWMs (for triac phase control), a high-current-drive 25-pin I/O bank, and a 10-bit ADC with up to 25 channels to read thermistor and mains-voltage sense lines. The CWG generates complementary switching with hardware dead-band, removing CPU jitter on motor drivers. Industrial -40C to +125C temperature rating covers appliance back-panel environments. Same-package PIC16F15344 / PIC16F15356 alternatives let designers tune Flash size without re-laying out.
Recommended
Touch/Proximity and HMI Front-Ends
Although the PIC16LF15354-E/ML lacks the mTouch CVD module of PIC16F1554, its four Configurable Logic Cells can implement simple capacitive sense with a single ADC channel and a CWG-driven excitation. At 32 MHz the device debounces, scans and refreshes an LED/HMI matrix without CPU-heavy interrupts. The 28-QFN footprint fits behind a glass panel, and the "LF" 1.8V operation runs from a coin cell when the host provides field-power. For higher-volume touch designs, validate against PIC16F1554 mTouch first.
Recommended
Industrial Sensor Transmitters and Metering
The PIC16LF15354-E/ML is well suited to 4-20 mA loop transmitters, gas/water meter data loggers and similar battery-isolated instruments. Its 1.8V-3.6V VDD lets it run from a single lithium primary cell, the 224-byte EEPROM stores calibration constants across 20-year deployments, and the 10-bit ADC with 25 channels conditions multiple sensor inputs simultaneously. Two EUSARTs handle local HART or MODBUS bridging, and the four CLCs implement custom timing logic that ordinarily would require a second timer IC. Drop-in PIC16F15354 variant supports 24V loop-powered 5V designs.
Recommended
Remote Control and Smart-Home Peripherals
For thermostats, blind controllers and Zigbee/BLE bridges that pair with a host MCU, the PIC16LF15354-E/ML adds deterministic peripheral scheduling around an external radio. The CLCs drive the radio's timing-critical hand-shake signals while the CPU sleeps, the CWG generates complementary FET drives for motorised blinds, and the EUSART/SPI/I2C ports provide a redundant control channel. The 28-QFN (6x6 mm) keeps the bill-of-materials in the sub-USD-2 range for the wireless module.
Recommended
Automotive Interior Sub-Modules (Non-Safety)
The PIC16LF15354-E/ML handles interior LED lighting, ambient-light controllers, HVAC flaps and seat actuators in non-safety automotive modules. Up to 25 I/Os with high-current drive simplify direct MOSFET connections, the four PWMs generate millions of colour-mixing steps for RGB interior strips, and the 1.8-3.6V LF range shares a common rail with most automotive PMICs. Designers specify the "E" industrial grade for cabin modules; for safety-critical ECUs they must upgrade to AEC-Q100-qualified PIC16F1xxx parts which Microchip publishes separately.

Key Differentiators
- Core Independent Peripherals (CLC, CWG, NCO) without extra silicon (vs PIC16LF15324-I/P)
- Wider 1.8V LF voltage range for direct coin-cell operation (vs PIC16F1455-I/P)
- 28-QFN package pins out 25 high-current I/Os (vs PIC16F15354-E/ML (same die, 5V))
Design Notes
Place a 0.1uF ceramic decoupling capacitor within 3 mm of every VDD pin (pins 1 and 27 on the 28-QFN package) plus a single 1uF bulk cap on the VDD rail. The LF silicon tolerates 1.8V operation, but transient current spikes during CWG switching can pull VDD out of spec; the bulk cap suppresses the resulting brown-out resets. Verify IDC and IOH against the 28-QFN package thermal limits at 32 MHz.
Always configure the PPS (Peripheral Pin Select) registers before assigning UART/SPI/I2C functions to physical pins - PPS defaults differ between PIC16F15354 sub-variants and an unassigned peripheral will drive 'noise' on unintended pins. Use the MPLAB Code Configurator's Pin Manager to generate the unlock sequence (PPSLOCK = 0x55 / 0xAA) once at startup; forgetting the lock unlock causes peripherals to silently fail. Estimated: this is standard PIC16F1xxx PPS behaviour per the family datasheet.
The 28-QFN exposed thermal pad (pin 28) MUST be soldered to a grounded copper pad of at least ~10 mm^2 for heat dissipation; this also lowers theta_JA from ~80 C/W to ~35 C/W. Route any high-frequency signals on the top layer only over a continuous ground plane, and keep ADC traces short and guarded to achieve the 10-bit ADC's full noise performance. Avoid routing SPI/SCL traces adjacent to the CWG outputs.
Compliance Information
Industrial-grade (-40C to +125C) only. For automotive cabin-modules downgrade to AEC-Q100-qualified PIC16F1xxx-M variants Microchip publishes separately.
