PIC16LF15325T-I/ST - 8-bit 32MHz 14KB Flash XLP MCU | Microchip
MPN： PIC16LF15325T-I/ST ✓ 啟用中PIC16LF15325T-I/ST 概覽
An 8-bit microcontroller (MCU) is a small computer-on-a-chip built around an 8-bit data path, optimized for low cost, deterministic real-time control, and ease of programming in embedded C or assembly. The PIC16 architecture sits within the broader hierarchy: PIC16 -> PIC10/12/14/16/18 family -> 8-bit MCU -> microcontroller -> embedded processing IC -> semiconductor. The 'LF' prefix denotes a wide-voltage, low-power variant engineered for eXtreme Low-Power (XLP) operation across battery-powered applications.
Key features include 14KB self-programmable Flash, 1KB SRAM, 256B EEPROM, 11 I/O pins, four 10-bit PWM channels, a 10-bit ADC with up to 11 channels, a 5-bit DAC, two comparators, CWG, four CLCs, and two EUSART peripherals supporting SPI/I2C. The 32 MHz internal oscillator yields 8 MIPS instruction throughput, while the nanoWatt XLP technology enables typical sleep currents below ~50 nA, allowing years of operation from a single coin cell.
Typical applications include battery-powered IoT sensor hubs, low-energy Bluetooth beacon controllers, consumer remote controls, home-automation nodes, intelligent lighting controllers, and compact sensor interfaces. Industrial use cases span HVAC peripheral controls, appliance user-interface boards, and any system where footprint, code simplicity, and sleep current outweigh raw throughput.
When designing with this device, prioritize the internal 32 MHz oscillator for BOM savings, but reserve a crystal option if the application demands tight UART timing. Ensure unused I/O are configured as outputs to minimize sleep current, and place the decoupling capacitor within 3 mm of the VDD pin to limit switching noise.

典型應用
PIC16LF15325T-I/ST 適用於 7 應用s: Battery-Powered IoT Sensor Node, Consumer Remote Control, Home-Automation / Smart Lighting Controller, Industrial Sensor Interface / HVAC Peripheral, Low-Energy Bluetooth Beacon Controller, Appliance User-Interface Board, Compact Sensor Hub / Data Logger.
Battery-Powered IoT Sensor Node
The PIC16LF15325T-I/ST is a strong fit for battery-powered IoT sensor nodes thanks to its nanoWatt XLP sleep technology with typical sleep currents below ~50 nA. Its 14 KB Flash and 1 KB SRAM comfortably fit typical sensor-fusion, periodic-sampling, and BLE-beacon firmware. The 10-bit ADC with up to 11 channels supports multiple analog sensors (temperature, humidity, light) on a single MCU. With the 32 MHz internal oscillator, the part wakes, samples, transmits, and returns to sleep within milliseconds - extending coin-cell life to multiple years when paired with a sub-GHz or BLE radio.
推薦
Consumer Remote Control
The PIC16LF15325T-I/ST fits consumer remote-control designs where low cost, low standby current, and small footprint dominate. Its 11 I/O pins drive keypad scanning, IR-LED modulation, and status LEDs without external glue logic. The CWG peripheral generates precise IR carrier waveforms, while the EUSART handles optional RF modules. Sleep currents below ~50 nA enable multi-year battery life on a pair of AA cells. The 14-TSSOP package occupies minimal PCB area - ideal for thin, lightweight remotes.
推薦
Home-Automation / Smart Lighting Controller
The PIC16LF15325T-I/ST is well suited for home-automation nodes and smart-lighting controllers that demand deterministic PWM, analog dimming, and low idle power. Its four 10-bit PWM channels drive multiple LED strings or triac dimmers, while the 5-/8-bit DAC provides smooth analog dimming curves. CLCs implement custom logic (fade-in/out, color mixing) without CPU intervention, freeing the core for communication. nanoWatt XLP sleep keeps wall-switch replacements running on harvested energy or small backup cells.
推薦
Industrial Sensor Interface / HVAC Peripheral
The PIC16LF15325T-I/ST serves industrial sensor-interface and HVAC-peripheral boards where stable ADC readings and robust peripherals matter more than throughput. Its 10-bit ADC with up to 11 channels reads thermistors, pressure transducers, and flow sensors. The two comparators implement window-detect alarm functions without software polling. Industrial temperature grade (-40C to +85C) supports factory-floor enclosures. The 14-TSSOP footprint and 32 MHz core deliver responsive control loops for variable-speed fans and damper actuators.
推薦
Low-Energy Bluetooth Beacon Controller
The PIC16LF15325T-I/ST is an excellent host for low-energy Bluetooth beacon designs where firmware size and sleep current are critical. Its 14 KB Flash holds beacon-format definitions (iBeacon, Eddystone) and advertising schedules. The EUSART interfaces with BLE modules at 115200 baud while CLCs handle timing-critical advertising windows. Sleep currents below ~50 nA combined with the radio's own low-power modes yield years of operation from a CR2032 cell. The compact 14-TSSOP package fits inside coin-cell holders.
推薦
Appliance User-Interface Board
The PIC16LF15325T-I/ST drives appliance user-interface boards (washers, microwaves, coffee makers) requiring keypad scanning, display multiplexing, and status indication. Its 11 I/O pins handle 4x4 keypads plus LCD or LED displays. The CWG generates buzzer tones for alerts without CPU load. Two EUSART modules connect to main appliance controllers and to debug interfaces during development. Industrial temperature grade and 14-TSSOP package suit the long-lifecycle, vibration-prone environment of consumer appliances.
推薦
Compact Sensor Hub / Data Logger
The PIC16LF15325T-I/ST serves as a compact sensor-hub or data-logger controller in portable instrumentation. Its 14 KB Flash and 256 B EEPROM store calibration constants, sample buffers, and configuration profiles. The 10-bit ADC with up to 11 channels multiplexes multiple sensors, while EUSART/SPI/I2C connect to external FRAM or SD-card storage. Sleep currents below ~50 nA and the LF wide-voltage operation enable battery-powered field data loggers that run for weeks on a single charge.

設計說明
The PIC16LF15325T-I/ST supports nanoWatt XLP technology with typical sleep currents below ~50 nA when peripherals are disabled. To achieve the lowest sleep current, configure all unused I/O as outputs, disable unused peripherals via PMD registers, and avoid floating analog inputs. For battery-powered designs, route VDD through a low-quiescent LDO such as the MCP1700 (1.6 uA Iq) to extend shelf life. Wake sources include Watchdog Timer, RTCC, and external interrupts on RA2/RA4.
Place the 0.1 uF VDD decoupling capacitor within 3 mm of the VDD pin (pin 14) and a bulk capacitor (1-10 uF) on the same rail. Keep the MCLR pull-up (typically 10 kohm) close to pin 3 to avoid spurious resets. For TSSOP packages, route clock traces on the opposite PCB layer and use a continuous ground plane beneath the device to reduce EMI. Avoid running high-current traces under the IC to minimize digital switching noise coupling into analog inputs.
Three common pitfalls when designing with the PIC16LF15325T-I/ST: (1) Configuring unused I/O as analog inputs - this allows them to float and waste current; set them as digital outputs low. (2) Using the internal 32 MHz oscillator with UART at high baud rates without calibration - tight UART timing may require a crystal or software calibration to stay within the +/-2% baud-rate tolerance. (3) Exceeding the absolute maximum VDD - the LF variant supports a wide but datasheet-defined VDD window; verify against the latest datasheet section 'Electrical Characteristics' before finalizing the power tree.
