PIC16LF15354-I/SO - 32MHz 7KB Flash 8-bit MCU, 28-SOIC | Microchip
MPN: PIC16LF15354-I/SO ✓ Hoạt độngPIC16LF15354-I/SO Tóm tắt
A microcontroller (MCU) is a single-chip computer containing a CPU core, non-volatile Flash program memory, volatile SRAM data memory, and a rich set of on-chip peripherals. The PIC16F15354 family sits within Microchip's mid-range 8-bit portfolio, offering Core Independent Peripherals (CIPs) such as Configurable Logic Cells (CLCs), Complementary Waveform Generator (CWG), and numerically-controlled oscillator (NCO) blocks. Within the broader semiconductor hierarchy, an MCU belongs to integrated circuits > microcontrollers > 8-bit microcontrollers > PIC16 family > PIC16F153xx sub-family. CIPs are differentiated by hardware-implemented state machines that offload tasks from the core, reducing code size and power consumption.
Key differentiating features include four 10-bit PWMs with complementary outputs, a 5-bit/8-bit DAC, a comparator, multiple CLCs, two EUSART modules (supporting LIN and RS-485), SPI/I2C, a 12-bit ADC with computation, and an on-chip temperature indicator. The integrated Memory Access Partition (MAP) and Device Information Area (DIA) provide bootloader support and unique per-device serial numbers for asset tracking. Power consumption is typically < 50 nA in Sleep with Watchdog Timer disabled and < 1 µA in Real-Time Clock mode, making the part suitable for battery-powered edge sensing.
Typical applications include consumer IoT sensor nodes, low-power wireless remote controls, home automation endpoints, HVAC thermostats, battery management front-ends, and small appliance controllers. Designers choose this part when they need deterministic 8-bit processing with rich analog and digital peripherals without stepping up to a 16-bit dsPIC or ARM Cortex-M0+ device.
When laying out the PCB, place a 100 nF decoupling capacitor within 3 mm of the VDD pin and a bulk 1 µF to 10 µF capacitor near the IC, save the same pattern on AVDD if used. MCLR must be tied to VDD through a 10 kΩ resistor (or driven by a supervisor) for reliable resets. The ICSP programming pins (ICSPCLK/ICSPDAT) should be reserved with test access to enable in-circuit firmware design.

Ứng dụng tiêu biểu
PIC16LF15354-I/SO phù hợp cho 6 Áp dụngs: Battery-Operated Wireless Sensor Nodes, PIR Motion and Occupancy Detectors, Home Automation Wireless Switches / Remote Controls, Small Appliance and HVAC Thermostat Front-Ends, Battery Management Front-Ends and Fuel-Gauge Hosts, Industrial Sensor Transmitters and 4-20 mA Loops.
Battery-Operated Wireless Sensor Nodes
The PIC16LF15354-I/SO is purpose-built for battery-powered IoT sensor endpoints: the LF variant operates from 1.8 V to 3.6 V, and Sleep current drops below ~30-50 nA with the Watchdog Timer disabled, ideal for coin-cell and 2×AAA deployments. The on-chip 12-bit ADC with computation, internal temperature indicator, and four Configurable Logic Cells let a single IC digitize, threshold-check, and wake-up the radio without CPU intervention. Placed alongside an SPI-attached transceiver like the MRF24J40 or an I2C sensor, the LF15354 typically achieves 10-year battery life on a 220 mAh CR2032 at <0.1% duty cycle.

PIR Motion and Occupancy Detectors
The PIC16LF15354-I/SO suits analog-front-end occupancy sensors because the integrated 12-bit ADC, dual comparators with internal DAC references, and four CLCs allow the analog chain (PIR + photodiode + microphone) to be processed and threshold-checked entirely in hardware, with the core waking only on a confirmed event. The on-chip temperature sensor enables environmental compensation for the pyroelectric signal. Compared to discrete analog designs, the LF15354 cuts Bill-of-Material count by 30-50% and enables firmware-tunable sensitivity, while the SOIC-28 footprint supports both through-hole PIR and SMD lens assemblies.
Được đề xuất
Home Automation Wireless Switches / Remote Controls
The PIC16LF15354-I/SO is a strong match for battery-powered wall switches and remote controls where Sleep current, tactile-debounce reliability, and BOM cost are critical. The CWG module drives a piezo buzzer or haptic feedback without extra timers, while the four PWMs could drive LED backlight indicators and RGB status LEDs. Paired with an SPI LoRa sub-GHz transceiver or an OOK/FSK ISM module, the LF15354 enables multi-year coin-cell battery life and supports capacitive-touch via the on-chip comparators and CLCs without dedicated touch ASICs.

Small Appliance and HVAC Thermostat Front-Ends
The PIC16LF15354-I/SO fits small-appliance control boards (coffee machines, blenders, fans) where one IC must read NTC temperature, drive TRIAC-controlled heater or BLDC motor via the CWG, and serve an HMI via UART/LEDs. The four 10-bit PWMs with complementary outputs and dead-band control pair well with the CWG to produce hardware-locked motor control waveforms, while two EUSARTs allow Modbus RTU communication with a main appliance controller. The 28-SOIC package is friendly to hand-solder rework and through-hole-reflow assembly lines.

Battery Management Front-Ends and Fuel-Gauge Hosts
The PIC16LF15354-I/SO serves as a low-power host MCU that monitors battery voltage and current, drives a 1-wire or I2C fuel gauge IC, and broadcasts state via UART or LED indicators. The 12-bit ADC with computation accumulates coulomb counts in hardware, while the internal band-gap reference and temperature indicator enable drift-corrected measurements across -40 °C to +85 °C. Compared to discrete battery-management designs, this single-chip approach reduces BOM count and improves Sleep-mode longevity, critical for cordless power tools and e-bikes.
Được đề xuất
Industrial Sensor Transmitters and 4-20 mA Loops
The PIC16LF15354-I/SO is suitable for industrial loop-powered sensor transmitters because of its wide -40 °C to +85 °C industrial grade rating and low Sleep current that meets the 3.5 mA minimum loop budget. The two EUSARTs and 12-bit ADC with computation support HART-modem or RS-485 sensor protocols, while the integrated CLCs provide hardware fault detection (open/short sensor wire). The 28-SOIC package withstands conformal coating and harsh-environment PCB processes commonly required in process-control applications.

Bảo phân biệt quan trọng
- Half the Flash and SRAM vs the 15355 family member while keeping 28-SOIC pin-for-pin (vsPIC16LF15355-I/SO)
- Wider voltage range on the F variant with same die and pinout (vsPIC16F15354-I/SO)
- More PWM, EUSART, and CLC channels vs the LF15344 sibling (vsPIC16LF15344-I/SO)
Ghi chú thiết kế
Place a 100 nF X7R 0.1 µF decoupling capacitor within 3 mm of VDD (pin 20) and VSS (pin 19), with a bulk 1 µF to 10 µF ceramic on the same node. The LF variant draws < 50 nA in Sleep with Watchdog disabled, but inrush during ADC conversion peaks at ~1.2 mA - the bulk cap prevents brown-out reset during wake-up events. Per Microchip AN-2285, AVDD (when used) should be tied directly to VDD or filtered with a ferrite bead for noise-sensitive ADC measurements.
Reserve the ICSP programming pins (ICSPCLK/ICSPDAT, alternate functions on RA1/RA0) on a 2.54 mm-pitch header footprint or test pad array, otherwise field firmware updates require rework. For SOIC-28, route ICSPCLK on a short trace away from PWM and switching signals to prevent noise-induced programming faults. The 28-SOIC land pattern should follow IPC-7351 nominal-density pads; Microchip's SOIC-28 land pattern recommendation is 1.78 mm x 0.6 mm with 1.27 mm pitch per JEDEC MS-013.
The on-chip 12-bit ADC achieves 12 ENOB only with proper PCB layout: keep analog traces short, surround ANx pins with a ground pour, and decouple VREF+ at pin 5 with 100 nF + 10 µF. According to Microchip AN-248 and the PIC16F15354 errata, ADC accuracy degrades by ~1 LSB if the analog supply shares impedance with digital switching loads. CLC outputs driving external FETs should be buffered if switching > 5 mA to prevent digital-supply noise coupling into analog inputs.
Configuration word mismatch is the most common bring-up issue: confirm WDTE, LVP (low-voltage programming), and oscillator settings match your development toolchain before locking the CONFIG bits. MCLR must be tied to VDD through a 10 kΩ resistor (or driven by a supervisor) - leaving it floating causes intermittent resets. When migrating from PIC16F15354 (5 V) to PIC16LF15354 (3.3 V), verify all peripherals and connected peripherals are 3.3 V tolerant. Estimated: at 3.3 V operation supply, the LF15354 has ~25% less dynamic current than the F variant due to lower internal logic swing, per Microchip DC characteristics tables.
