PIC16LF15354-E/SS Overview
An 8-bit microcontroller (MCU) is a single-chip computer built around an 8-bit data path, optimized for embedded control tasks such as sensor interfacing, motor driving, and user I/O management. The PIC16(L)F153xx family sits within Microchip's 8-bit MCU hierarchy: MCU -> 8-bit PIC -> PIC16 enhanced mid-range -> PIC16LF153xx series -> power-management-oriented peripheral set, with XLP technology making it particularly attractive for always-on IoT nodes.
Key peripherals include four 10-bit PWM outputs, a 10-bit ADC with computation, two comparators, a 5-bit DAC, a Complementary Waveform Generator (CWG), four Configurable Logic Cells (CLC), two EUSART modules, SPI, and I2C. These Core Independent Peripherals (CIPs) handle tasks in hardware without CPU intervention, reducing code complexity and active-mode power. The device also offers a built-in temperature indicator and Memory Access Partition (MAP) for bootloader-style protection.
Typical applications include consumer IoT sensor nodes, low-power wireless remote controls, HVAC thermostat controls, small appliance user interfaces, and battery-backed accessories. The combination of XLP sleep currents (sub-uA typical) and rich analog peripherals makes it well-suited for touch/proximity sensing, LED driving, and remote-control products. A wide selection of 28-pin SPDIP, SSOP, SOIC, and UQFN packages enables PCB adaptation across prototype and production builds.
When designing with this MCU, ensure decoupling is placed close to VDD/AVDD/VSS pins and that the on-chip debugging pinout (RB7/ICSCLK and RB6/ICSDA) is left accessible during prototype bring-up, or connected to programming headers in production. For always-on systems, leverage the CWG and CLC to keep the CPU asleep during peripheral activity.

Typical Applications
PIC16LF15354-E/SS is suitable for 6 applications: Battery-Powered IoT Sensor Node, HVAC Thermostat and Climate Control, Low-Power Remote Control / Wireless Key Fob, Small Appliance User Interface Board, Touch and Proximity Sensing Front End, Industrial Sensor Hub (Low-Voltage).
Battery-Powered IoT Sensor Node
The PIC16LF15354-E/SS is well suited for coin-cell or 2xAA battery-powered IoT sensor nodes thanks to its 1.8 V-3.6 V operating range and eXtreme Low-Power (XLP) sleep currents in the sub-microampere range. Per the Microchip datasheet, the 4 CLC blocks and CWG allow periodic sensor read or pulse generation without waking the CPU, giving multi-year battery life on a typical 240 mAh CR2032. Recommended companions include the MCP9808 temperature sensor and the MRF24J40 2.4 GHz transceiver (or equivalent sub-GHz modules) for periodic wireless reporting. The 28-SSOP package fits into small sensor node PCBs and the extended -40C to +125C temperature rating allows outdoor or industrial deployments.
Recommended
HVAC Thermostat and Climate Control
The PIC16LF15354-E/SS fits HVAC thermostat designs where multiple sensors (temperature, humidity) and actuators (relays, triacs) must be coordinated without constant CPU activity. Per Microchip's PIC16F15354 product page, the on-chip 10-bit ADC with computation, 2 comparators, and CWG let the device drive zero-cross triac control while sampling thermistor inputs with hardware averaging. The 32 MHz CPU and 4 PWMs handle display backlight dimming and buzzer feedback, while the XLP idle modes keep standby power below energy-star limits. Recommended companions include the MCP9700 analog temperature sensor and an SPI-driven OLED or character display for the thermostat UI.
Recommended
Low-Power Remote Control / Wireless Key Fob
The PIC16LF15354-E/SS is a strong choice for handheld remote controls and key-fob transmitters where deep sleep current dominates battery life. With XLP sleep in the sub-uA range and the ability to wake on pin change or WDT overflow, the device can sit dormant for years between button presses, per Microchip's PIC16LF153xx family literature. The 4 PWMs and CWG can directly drive status LEDs and piezo buzzers; the two EUSART modules and SPI/I2C support a companion sub-GHz or 2.4 GHz transceiver. The 28-SSOP package helps meet thin-form-factor industrial design requirements, while the extended temperature rating supports outdoor or automotive-trim applications.
Recommended
Small Appliance User Interface Board
Small kitchen and household appliances - coffee machines, blenders, slow cookers - often need a user interface MCU that can drive segmented LCD or LED indicators, read capacitive or resistive buttons, and time-sequence motors. The PIC16LF15354-E/SS provides 4 PWMs (for LED dimming and buzzer tone), 2 comparators (for AC zero-cross detection), and an on-chip 5-bit DAC to bias reference nodes - all without external glue logic, per the Microchip datasheet. The 28-SSOP form factor is straightforward for both hand-soldered prototypes and SMT assembly. Recommended companions include the TPL0102 digital potentiometer for user-adjustable setpoints and MCP4018 for trim storage of calibration values.
Recommended
Touch and Proximity Sensing Front End
Although the PIC16LF1554 family is Microchip's dedicated mTouch CVD family, the PIC16LF15354-E/SS still supports low-channel capacitive touch via its ADC2 module with hardware accumulation and software filtering. Per the PIC16LF1554/1559 datasheet, the CVD technique uses the ADC and reference capacitor network to measure capacitance changes caused by finger proximity - the same peripheral architecture is available on the 15354. The CLC and CWG blocks can produce haptic-driver waveforms on the I/O pin directly, without CPU activity. Recommended companions include charge-sharing protection diodes (ESD array) and a low-dropout regulator such as MCP1700 for stable touch references.
Recommended
Industrial Sensor Hub (Low-Voltage)
Industrial sensor hubs that aggregate 4-20 mA loop readings, thermistor inputs, and digital switch contact closures benefit from the PIC16LF15354-E/SS combination of CIP-based timing and 5 V-tolerant input structures (within the absolute-maximum range). Per the datasheet, the CLC blocks can implement an event-peripheral filter chain - debouncing inputs and pre-scaling counters - before the CPU wakes, which reduces BOM cost vs external logic. The 1.8 V-3.6 V range and 32 MHz core suit 4-20 mA current-loop powered sensors with on-board isolated DC-DC. Recommended companions include the MCP3421 18-bit ADC for precision analog and the MCP2515 CAN controller for industrial fieldbus connectivity.

Key Differentiators
- Wider CIP peripheral set vs general PIC16F1xxx family (vs PIC16LF1509-I/SS)
- 1.8 V minimum VDD for low-voltage battery systems (vs PIC16F15354-E/SS)
- Higher 32 MHz CPU performance vs older 20 MHz PIC16 families (vs PIC16LF1513-I/SS)
Design Notes
Estimated: power decoupling on the PIC16LF15354-E/SS should place a 100 nF ceramic on each VDD/AVDD pin, with an additional 1 uF bulk capacitor near the package. Inductive loads (relays, solenoids) require reverse-diodes - the 1.8 V-3.6 V range does NOT tolerate 5 V on input pins. For battery designs with MCU active at 1 MHz and sub-uA sleep, an MCP1700 LDO can substitute for direct coin-cell usage when the load demands short active-current pulses larger than the cell's internal resistance can supply.
Estimated: the PIC16LF15354-E/SS shares its pinout with the 15344/15345 but differs in flash size. Verify the flashed image size matches the target device's flash array to avoid write-timeouts during ICSP. Also, note the 28-SSOP part has pin 1 at RA0/ICSPDAT - reversed ICSP connectors will fail to communicate silently. Always include the ICSP/SWD 6-pin header on prototype builds for in-circuit programming and debugging.
At full 32 MHz operation on 3.3 V, total IDD is roughly 5 mA active (per Microchip datasheet DC characteristics) and falls to sub-uA in XLP sleep with retention. The 28-SSOP at ~5 mW active and 28-SSOP theta_JA of approximately 100 C/W experiences negligible self-heating; the extended -40C to +125C grade covers outdoor enclosures without derating.
Compliance Information
RoHS and lead-free per Microchip product page. Not AEC-Q100 qualified - choose AEC-Q100 parts (where available) for automotive applications.
