PIC16LF15345-I/SS - 8-bit 32MHz XLP MCU, 14KB Flash | Microchip
MPN: PIC16LF15345-I/SS ✓ Hoạt độngPIC16LF15345-I/SS Tóm tắt
A microcontroller (MCU) is a single-chip computer that integrates a CPU, memory, and programmable peripherals. The PIC16 family is Microchip's enhanced mid-range 8-bit architecture, positioned between the baseline PIC10/12/16 and the 16-bit dsPIC families, and is widely used in cost-sensitive embedded control. The 'LF' prefix denotes the eXtreme Low-Power (XLP) variant with a 1.8V to 3.6V operating range and ultra-low sleep currents, while the non-LF 'F' parts operate from 2.3V to 5.5V.
Key features include 4 configurable logic cells (CLC), a complementary waveform generator (CWG), a 5-bit DAC, comparators, 10-bit ADC with computation, 4 PWMs, 2 EUSART modules, and SPI/I2C peripherals - all classified as Core Independent Peripherals (CIPs) that offload tasks from the CPU. Peripherals can operate while the core sleeps, enabling event-driven designs that extend runtime on coin-cell batteries. The 20-pin SSOP footprint is one of the most widely used microchip packages, simplifying hand-prototyping and PCB layout reuse across the family.
Typical applications include consumer electronics, IoT sensor nodes, low-power wireless modules, home appliances, and battery-powered handheld instruments. The wide peripheral set also supports motor control, LED lighting, and simple user-interface subsystems. When designing with this MCU, consider using MPLAB X IDE with the XC8 compiler and PICkit or Snap programmer for development. Verified pricing and stock are available as of 2026-09-23 across DigiKey, Mouser, and Octopart.

Ứng dụng tiêu biểu
PIC16LF15345-I/SS phù hợp cho 7 Áp dụngs: Battery-Powered IoT Sensor Node, Home Appliance Control, LED Lighting and Signage, Consumer Handheld Devices, Automotive Body and Interior Modules, Industrial Sensor and Control Modules, Smart Home Wireless Nodes.
Battery-Powered IoT Sensor Node
The PIC16LF15345-I/SS is purpose-built for IoT sensor nodes where every microamp matters. Its 1.8V-3.6V XLP voltage range allows direct connection to single 3V coin cells (CR2032) or single-cell Li-ion/LiPo batteries, while nanoamp-range sleep currents extend runtime to years on a single battery. The 4 Core Independent Peripherals (CLC, CWG, comparators, timers) keep event processing active while the CPU sleeps, and the 10-bit ADC with computation handles sensor digitisation without waking the core. Combined with 2 EUSART modules and SPI/I2C, the MCU can interface LoRa, BLE modules, or environmental sensors. The 20-pin SSOP package is easy to hand-solder for prototype nodes.

Home Appliance Control
The PIC16LF15345-I/SS fits home appliance controllers - washing machines, dishwashers, microwave ovens, and HVAC controls - where reliability and cost matter more than raw CPU speed. The 4 PWM modules drive motor and valve control, the CWG generates complementary drive signals for half-bridge power stages, and the 10-bit ADC reads temperature sensors and current shunts. The industrial -40C to +85C temperature range covers appliance thermal environments. The 20-SSOP package provides through-hole-like mechanical robustness with surface-mount manufacturing, and the 14KB Flash accommodates full user-interface plus motor-control firmware in a single chip.

LED Lighting and Signage
The PIC16LF15345-I/SS drives LED lighting products including architectural strips, RGB color-mixing fixtures, and digital signage controllers. The 4 PWM channels provide individual dimming control for RGBW channels, while the CWG generates high-frequency complementary drive for synchronous buck or boost LED drivers. The 5-bit DAC enables logarithmic dimming curves matching human eye perception, and the 10-bit ADC reads ambient light sensors for daylight harvesting. The 32MHz core handles DMX512 or DALI protocol parsing in software, and the 14KB Flash supports full color-space conversion firmware. XLP low-power modes suit battery-powered decorative fixtures.

Consumer Handheld Devices
The PIC16LF15345-I/SS powers consumer handheld products such as remote controls, electronic toys, fitness bands, and personal-care devices. The 1.8V-3.6V operating range supports direct alkaline battery stacks (2xAAA in series gives 3V), and the XLP sleep currents enable multi-year battery life. The 14KB Flash accommodates USB HID, IR protocol, or BLE command-and-control firmware, while the 1KB SRAM handles protocol buffers. Hardware PWM drives buzzers and vibration motors, and the comparators detect low-battery and USB-VBUS presence. The 20-SSOP package is small enough for compact handheld enclosures yet easy to manufacture.

Automotive Body and Interior Modules
The PIC16LF15345-I/SS suits cost-sensitive automotive body and interior applications including mirror controllers, seat-position switches, ambient lighting, and HVAC vent motors. The 4 PWMs drive small DC and stepper motors for vent positioning, the ADC reads position feedback potentiometers, and the comparators detect switch closure with debouncing. Although not AEC-Q100 qualified, the -40C to +85C industrial temperature range covers most cabin environments. The 20-SSOP footprint is shared across the PIC16 family for PCB reuse across vehicle platforms. For under-hood or AEC-Q100-required applications, choose the AEC-Q100-graded variant from the same family.

Industrial Sensor and Control Modules
The PIC16LF15345-I/SS is well-suited to industrial 24V sensor modules, process transmitters, and small PLC expansion cards. The 2 EUSART modules support RS-485 and RS-232 simultaneously via external transceivers, SPI/I2C connect to digital sensors and EEPROMs, and the ADC reads 4-20mA loop signals through a shunt. The CLCs implement hardware debouncing and frequency-to-digital conversion for flow sensors. The industrial temperature range -40C to +85C supports factory-floor environments, and the SSOP-20 package fits DIN-rail-mounted enclosures. The 14KB Flash handles Modbus RTU slave protocol plus calibration firmware.

Smart Home Wireless Nodes
The PIC16LF15345-I/SS provides the host MCU for Zigbee, Z-Wave, LoRa, or sub-GHz wireless nodes in smart-home products. The MCU runs the wireless protocol state machine while its peripherals handle user input (buttons, capacitive touch via CLCs) and output (PWM-controlled LED indicators). The XLP sleep between STM32 (0.5uA typical) combined with wake-on-radio interrupts keeps battery-powered door sensors, window sensors, and leak detectors operational for years. The 14KB Flash supports Zigbee 3.0 stack or LoRaWAN MAC, and the SSOP-20 package allows compact PCB designs behind wall plates.

Ghi chú thiết kế
Decouple VDD with a 100 nF ceramic capacitor placed within 5 mm of pin 11, plus a bulk capacitor (4.7 uF to 10 uF) at the board power entry. For XLP designs targeting sleep currents below 1 uA, ensure no leakage paths through pull-ups, voltage dividers, or unused peripherals. The PIC16LF15345-I/SS datasheet recommends disabling unused modules via the PMD (Peripheral Module Disable) registers to minimize active current draw during sleep. Estimated: with all peripherals disabled, the LF part achieves <100 nA typical sleep current at 3 V.
Route the ICSP programming lines (RA0/ICSPCLK, RA1/ICSPDAT or RB6/RB7 alternate pair) to an in-circuit programming header with no series resistors in the signal path. Place the programming header at the board edge for probe access. Keep the MCLR pull-up (typically 10 kohm) close to pin 4 to avoid noise-induced resets. For SSOP-20 packages, use 0.65 mm pitch traces and ensure the SSOP thermal pad (if present) connects to a small ground pour to aid reflow soldering.
Do not exceed 3.6 V on VDD - the LF variant is permanently damaged above this. Do not connect analog signals exceeding VDD to ADC inputs without clamping. The configuration words (fuses) must be set correctly - especially the WDTE (watchdog timer enable), LVP (low-voltage programming), and FOSC (oscillator selection). Forgetful configuration of FOSC prevents the MCU from oscillating. Always verify the config word settings in MPLAB X IDE before programming. The /SS suffix denotes SSOP package and -I denotes industrial -40C to +85C temperature range.
