PIC16F15245T-I/SS 개요
A microcontroller (MCU) is a single-chip computer that integrates a CPU, memory (Flash for code, SRAM for data, EEPROM for non-volatile storage), and programmable peripherals. The 8-bit PIC16 family is positioned as a cost-effective platform for sensor interfacing, real-time control, and low-power IoT endpoints, sitting below 16-bit and 32-bit MCUs in computational capability but offering the lowest active and sleep current per feature in Microchip's portfolio.
Key features of the PIC16F15245T-I/SS include a 10-bit Analog-to-Digital Converter (ADC), two PWM outputs, two Capture/Compare/PWM (CCP) modules, a Hardware Limit Timer (HLT), Watchdog Timer (WDT), Peripheral Pin Select (PPS) for flexible signal routing, plus EUSART, SPI, and I2C communication peripherals. The device also supports the XLP SLEEP mode for nanoWatt sleep currents.
Architecturally, the PIC16F15245 uses an enhanced mid-range 8-bit core with hardware multiply assist and a 14-bit instruction word, paired with Core Independent Peripherals (CIPs) that operate without CPU intervention. The CIP approach reduces firmware complexity and enables deterministic real-time response, which is critical in cost-sensitive sensor and control applications.
Typical applications include consumer appliances, IoT sensor nodes, battery-powered handheld instruments, LED lighting controllers, and small motor control. The wide 2.5V-5.5V supply range and low-power sleep modes make it especially well suited to energy-harvesting and battery-backed designs. The 20-SSOP package also allows compact board layouts with sufficient I/O for typical sensor plus communication interfaces.
When designing with this MCU, ensure the configuration bits are properly set for brown-out reset, watchdog enable, and low-voltage programming. The PPS feature allows remapping of digital peripherals to most I/O pins, simplifying PCB layout when routing EUSART, SPI, or PWM signals.

일반적인 애플리케이션
PIC16F15245T-I/SS 적합 용도: 6 애플리케이션s: Battery-Powered IoT Sensor Nodes, Consumer Appliance Control, LED Lighting Controllers, Handheld Measurement Instruments, Small Motor Control (Fans, Pumps, Blowers), Industrial Sensor and Real-Time Control.
Battery-Powered IoT Sensor Nodes
The PIC16F15245T-I/SS's XLP nanoWatt SLEEP mode draws nanoamp-level sleep current and the part wakes in microseconds from its 32MHz internal oscillator, making it ideal for battery-powered IoT sensor nodes. With 14KB Flash it accommodates small wireless sensor protocol stacks and CIP-driven sensor sampling without external RTOS overhead. Its 2.5V-5.5V supply range accepts a single Li-ion or 2xAA cell, eliminating the boost converter that many low-power sensors require. EUSART or SPI can drive a sub-GHz radio such as the MRF89XA, while the 10-bit ADC reads thermistor, photodiode, or soil-moisture sensors directly.
추천
Consumer Appliance Control
The PIC16F15245T-I/SS is well suited for consumer appliance control boards where deterministic real-time response is required. Its 2 PWM channels plus 2 CCP modules drive small brushless DC fans, solenoids, or LED indicator drivers, while the 10-bit ADC reads thermistors for over-temperature protection. Core Independent Peripherals (CIPs) like the Hardware Limit Timer (HLT) execute safety-critical timing without CPU intervention, improving reliability over firmware-based loops. The 20-SSOP package and 2.5-5.5V range accept 3.3V or 5V rails common in white-goods designs, and PPS lets engineers remap signals to ease PCB routing.
추천
LED Lighting Controllers
The PIC16F15245T-I/SS drives LED lighting controllers through its 2 PWM channels and 2 CCP modules, supporting color-mixing and dimming up to several hundred hertz without flicker. The 10-bit ADC provides closed-loop current sensing for constant-current LED drivers, while PPS allows the PWM outputs to be reassigned to any I/O pin for easier PCB layout. With 14KB Flash the device stores multiple lighting profiles and fade tables, and XLP sleep enables standby power well below 1µA for Energy Star compliant fixtures. The 32MHz core computes CIE color-mixing or DMX-style frame decoding at sufficient throughput.
추천
Handheld Measurement Instruments
The PIC16F15245T-I/SS is a fit for handheld measurement instruments such as digital multimeters, portable environmental meters, and basic oscilloscope probes where low power and small footprint are critical. The 32MHz core drives EUSSR or SPI displays and the 10-bit ADC captures sensor inputs directly; CIP-based timing offloads measurement sequencing from firmware, reducing code complexity. XLP nanoWatt sleep extends battery life between charges, and the 20-SSOP package fits inside slim plastic enclosures. PPS routing simplifies laying out the ADC input trace near the analog front end for best noise performance.
추천
Small Motor Control (Fans, Pumps, Blowers)
The PIC16F15245T-I/SS handles small motor control for fans, pumps, and blowers using its 2 PWM channels for speed regulation plus the 10-bit ADC for back-EMF or current sensing. The Hardware Limit Timer (HLT) CIP provides hardware-protected over-current shutdown without firmware latency, and the enhanced mid-range 8-bit core executes PI control loops fast enough for closed-loop PWM at 25kHz. The 32MHz clock and 14KB Flash support field-oriented control tables and soft-start ramps, while the 20-SSOP and 2.5-5.5V range suit 5V or 12V BLDC driver boards.
추천
Industrial Sensor and Real-Time Control
The PIC16F15245T-I/SS suits industrial sensor and real-time control nodes where deterministic Core Independent Peripheral execution is required. The CIPs - including HLT, CCP, and PWM - run timing-critical functions without CPU load, while EUSART, SPI, and I2C connect to industrial sensors, isolated transceivers, or HMI displays. The industrial -40C to +85C temperature grade plus 2.5-5.5V tolerance handles 24V-derived 5V or 3.3V rails common in PLCs and field instruments. With 14KB Flash and 1KB SRAM the part accommodates Modbus RTU stacks, sensor calibration tables, and diagnostic log buffers.

설계 노트
Decouple VDD with a 100 nF ceramic capacitor placed within 5 mm of the VDD pin, plus a bulk 1-10 uF capacitor if the rail is shared with motors or RF. The PIC16F15245T-I/SS operates from 2.5-5.5V, but brown-out reset (BOR) must be enabled in configuration bits to guarantee safe startup when batteries sag. Estimated: at 32 MHz active, IDD is typically a few mA, while XLP sleep draws nanoamps - design battery-life budgets around sleep current, not active current.
Configuration bits must be set before code execution - leaving MCLRE enabled can cause programming issues, and disabling WDT may prevent recovery from firmware lockups. Per Microchip PIC16F152xx datasheet, the PPS feature only assigns peripherals to specific pins, so always cross-check the pinout table for remappable functions. The 10-bit ADC reference can be VDD or a dedicated VREF+ pin; tie VREF+ to a stable, low-noise source for best ADC accuracy.
Keep the analog ADC traces short and away from PWM or switching signals to minimize coupling. The PIC16F15245T-I/SS 20-SSOP package has ground on pins 7 and 18 - stitch both to a low-impedance ground plane for thermal and EMI performance. Place the ICSP programming header (PGD/PGC) near the MCU with no series resistors in the production board to allow in-circuit debugging via MPLAB ICD.
