PIC16F15245-E/SO 개요
An 8-bit microcontroller (MCU) is a single-chip computer built around an 8-bit data path that executes one byte per instruction cycle; PIC MCUs sit in the broader taxonomy of microcontroller -> embedded computing device -> semiconductor IC. The PIC16F15245 belongs to Microchip's enhanced mid-range PIC16 family, which uses a 14-bit instruction word and a 16-level hardware stack, offering a balance of deterministic real-time control, low power consumption, and Core Independent Peripherals (CIPs) that offload tasks from the CPU. This class of MCU is widely used in cost-sensitive sensor and real-time control designs where deterministic response and low quiescent current matter more than raw compute throughput.
Key features of the PIC16F15245-E/SO include its 32MHz internal oscillator (8MHz with 4x PLL), 14KB Flash, 1KB RAM, 10-bit ADC with internal voltage reference and computation modes, two CCP and two PWM peripherals, and Microchip's eXtreme Low-Power XLP sleep mode with nanoWatt XLP technology. The Peripheral Pin Select (PPS) block allows flexible remapping of digital peripherals to any I/O pin, which simplifies PCB routing and supports multiple communication stacks on a fixed pinout. On-chip Core Independent Peripherals such as the Hardware Limit Timer (HLT) and Configurable Logic Cell (CLC) let state machines and timing-critical loops run without CPU intervention.
Typical applications include sensor node conditioning and IoT edge devices, low-power battery-powered consumer products, home automation controllers, white-goods user-interface boards, LED lighting drivers with PWM dimming, and cost-sensitive industrial control logic. The combination of 14KB Flash, 1KB RAM, PPS, and the 10-bit ADC with computation (ADC2) also makes this device well suited to PID-style closed-loop control, multi-channel sensor readout, and simple user-interface HMI designs that need reliable real-time response.
When designing with this part, note that the 'E' suffix designates the extended (-40C to +125C) operating temperature range and 'SO' is the 20-pin SOIC (300-mil) package. PPS remapping must be configured before enabling peripheral output, and the ADC's computation modes benefit from a dedicated 1.2V band-gap reference for ratiometric measurements. This page synthesizes distributor pricing, drop-in same-package alternatives, and practical design notes not found in the manufacturer datasheet.

일반적인 애플리케이션
PIC16F15245-E/SO 적합 용도: 6 애플리케이션s: Battery-Powered IoT Sensor Node, Home Appliance User Interface Board, LED Lighting Controller with PWM Dimming, Industrial Sensor Conditioning Module, Automotive Accessory Controller, Consumer Wearable / Fitness Device.
Battery-Powered IoT Sensor Node
The PIC16F15245-E/SO is well matched to battery-powered IoT sensor nodes because its eXtreme Low-Power (XLP) sleep mode typically draws under 50 nA with the RTC and WDT active, while the 32MHz core wakes in microseconds to service sensor reads. The 10-bit ADC with computation modes and on-chip voltage reference supports ratiometric measurements of thermistors, photodiodes, and load cells without external analog front-end. MSSP SPI/I2C connects to digital sensors and EEPROM, while EUSART links to radios. At 1.18 USD/100 pieces, it is price-competitive with discrete MCU + supervisor designs in SOIC-20.
추천
Home Appliance User Interface Board
The PIC16F15245-E/SO is widely used in white-goods HMI boards where it scans key matrices, drives LED indicators via PWM, and talks to the main controller over UART. The PPS block lets designers remap EUSART, SPI, and PWM to convenient pins on the SOIC-20 footprint, simplifying single-layer PCB layouts. Two CCP and two PWM channels drive backlight dimming and buzzer tones, while the Hardware Limit Timer (HLT) implements debounce and watchdog-style timeout logic without CPU load. The extended -40 C to +125 C temperature grade supports under-cabinet and outdoor appliance installations.
추천
LED Lighting Controller with PWM Dimming
The PIC16F15245-E/SO delivers precise PWM dimming for LED drivers by providing two dedicated PWM peripherals plus two CCP modules in software PWM mode, all driven from the same 32MHz time base. PPS routes PWM outputs to any GPIO, allowing multiple LED channels on the SOIC-20 footprint without remapping the silicon. The 10-bit ADC senses supply current and ambient light for closed-loop brightness control. Low sleep current (<1 uA typical with WDT) makes the part ideal for always-on standby lighting fixtures that must meet Energy Star standby budgets.
추천
Industrial Sensor Conditioning Module
In industrial 4-20 mA loop-powered sensor transmitters, the PIC16F15245-E/SO provides a 10-bit ADC for transducer readout, an EUSART or SPI channel for digital communication, and PWM output that can synthesize the 4-20 mA loop current when paired with a current driver. Peripheral Pin Select allows the same SOIC-20 layout to be reused across RTD, thermocouple, and strain-gauge variants by simply swapping firmware. The extended -40 C to +125 C operating range and Core Independent Peripherals (CLC, HLT) deliver deterministic real-time response without CPU jitter.
추천
Automotive Accessory Controller
The PIC16F15245-E/SO is suitable for non-safety automotive accessories such as interior lighting controllers, seat heaters, and aftermarket gauge clusters where the extended -40 C to +125 C grade and SOIC-20 form factor are needed. Two CCP/PWM channels drive resistive heaters and fans with hardware-timed duty cycles, while EUSART provides LIN or UART communication with the vehicle body controller. PPS lets engineers reassign UART TX/RX, PWM, and ADC inputs to the same PCB layout across multiple SKUs, reducing tooling cost. For higher-reliability powertrain or ADAS designs, consider the AEC-Q100-graded PIC16F15245-E/SOVAO variant listed on Octopart.
추천
Consumer Wearable / Fitness Device
The PIC16F15245-E/SO supports compact fitness wearables by combining the 10-bit ADC for heart-rate and motion sensor readout, MSSP (SPI/I2C) for digital accelerometer/gyro interfaces, and EUSART for Bluetooth HCI bridges to a paired radio module. The XLP sleep mode keeps average current below 10 uA between sensor reads, extending coin-cell life to months. The 20-pin SOIC footprint is friendly to small rigid-flex PCBs, and the -40 C to +125 C range tolerates body-temperature and outdoor-sport environments. PPS allows the firmware to reuse the same PCB for different sensor stacks.

설계 노트
Estimated: at 32 MHz active and 3.3 V supply, the PIC16F15245-E/SO core typically draws ~3 mA; in XLP sleep with WDT enabled and RTCC active, the device drops to <1 uA. For battery-powered designs, route MCLR through a 10 kohm pull-up and place a 100 nF decoupling capacitor within 5 mm of VDD; add a 10 uF bulk cap on the same rail. PPS-remappable peripherals allow digital-only I/O pins to stay in high-impedance during sleep, eliminating per-pin pull-up leakage.
The SOIC-20 footprint has 1.27 mm pin pitch. Keep the ICSP/ICD connector (RB6/RB7) trace length under 50 mm and avoid routing these traces near PWM switching edges. Place a ground pour under the device and stitch VSS pin 8 to the pour with at least two vias. For ADC accuracy, isolate the analog AVSS/AVDD pair from digital switching currents by using a ferrite bead on AVDD when present, otherwise use the internal 1.2V band-gap reference for ratiometric measurements.
Critical: PPS peripheral output mapping must be unlocked (PPSLOCK = 0) and remapped before the peripheral is enabled - a common firmware bug leaves TX or PWM lines on the default pin even after PPS configuration. The CONFIG words must be programmed explicitly; leaving them at the default un-programmed state disables the PLL and limits the core to 4 MHz. For ADC, allow at least 5 us of acquisition time on high-impedance sources and use ADCON0<CHS> rather than the legacy ANSEL register, which is mapped differently on PIC16F152xx.
