PIC16F15244-E/SO - 8-bit PIC16 MCU, 7KB Flash, SOIC-20 | Microchip
MPN： PIC16F15244-E/SO ✓ 啟用中PIC16F15244-E/SO 概覽
A microcontroller (MCU) is a single-chip computer that integrates a CPU, non-volatile program memory, working RAM, and a rich set of programmable peripherals. The PIC16F152xx family is positioned inside the broader PIC16 mid-range family (an 8-bit PIC MCU family), itself part of Microchip's 8-bit MCU portfolio that competes with other 8-bit architectures for embedded control. As a Flash-based MCU, the PIC16F15244 supports in-circuit serial programming (ICSP) and field re-programmability, which lowers lifecycle cost for production and field updates.
Key features include a 10-bit ADC with multiple channel options, two PWM modules, two CCP (Capture/Compare/PWM) modules, hardware limit timer (HLT), watchdog timer (WDT), peripheral pin select (PPS), EUSART, SPI, and I2C. The device operates from 1.8 V to 5.5 V across an industrial -40 C to +125 C temperature range and supports the eXtreme Low-Power (XLP) SLEEP mode for battery-aware designs. According to Microchip product documentation, the PIC16F15244 family adds Core Independent Peripherals (CIPs) and Intelligent Analog blocks that offload tasks from the CPU.
Architecturally, the part uses a Harvard RISC architecture with separate program and data buses, plus the enhanced mid-range instruction set, which gives deterministic interrupt latency for real-time loops. The wide SOIC-20 (SO) footprint and PPS-based I/O remapping simplify PCB layout reuse across the PIC16F152xx family; Microchip's migration guide notes that PIC16F15244 devices serve as direct drop-in replacements for legacy PIC12F parts in SOIC packages.
Typical applications include IoT sensor nodes, industrial automation modules, consumer appliance control boards, battery-powered measurement instruments, and compact motor/lighting controllers. For designs migrating from older PIC12F or PIC16F1xxx parts, the SOIC-20 footprint and PPS simplify schematic carry-over.
When designing with this MCU, plan for decoupling capacitors on VDD/AVDD, follow Microchip's recommended decoupling guidance, and verify that your chosen compiler (XC8) version supports the PIC16F15244 device header. Production programmers such as MPLAB SNAP, PICkit 4, or MPLAB ICD 4 are compatible for in-circuit debug.

典型應用
PIC16F15244-E/SO 適用於 6 應用s: IoT Sensor Nodes, Industrial Automation Modules, Consumer Appliance Control, Battery-Powered Measurement Instruments, LED Lighting Controllers, Automotive Body and Comfort Electronics.
IoT Sensor Nodes
The PIC16F15244-E/SO fits IoT sensor nodes thanks to its 1.8-5.5 V supply range, XLP eXtreme Low-Power SLEEP mode, 10-bit ADC, and 32 MHz CPU. Its nanoamp-class SLEEP current supports coin-cell or 2xAA battery operation for multi-year deployments. PPS remaps EUSART, SPI, and I2C to nearly any I/O pin, simplifying PCB routing when sensors are placed near board edges. The 7.168 KB Flash accommodates BLE-command parsers, periodic sample buffering, and OTA-friendly boot structures.
推薦
Industrial Automation Modules
For industrial PLC blocks, sensor-conditioning modules, and small motor drivers, the PIC16F15244-E/SO offers 2 PWM, 2 CCP, hardware limit timer, and a 10-bit ADC inside an industrial -40 C to +125 C qualified SOIC-20. Core Independent Peripherals (CIPs) handle timing and signal generation without CPU load, freeing cycles for protocol stacks. PPS allows flexible PCB layout when routing analog sensor signals alongside digital communication lines.
推薦
Consumer Appliance Control
The PIC16F15244-E/SO drives consumer appliances such as coffee machines, washing-machine sub-modules, and small kitchen electronics. Its 32 MHz CPU delivers responsive HMI timing, and the 10-bit ADC reads temperature/humidity/potentiometer sensors accurately. Two PWM channels can dim LEDs or modulate fan speed, while EUSART links to a host display board. Industrial-grade temperature tolerance handles under-cabinet heat-rise scenarios.
推薦
Battery-Powered Measurement Instruments
Portable DMMs, hand-held gas detectors, and field-calibration tools benefit from the PIC16F15244-E/SO's XLP SLEEP, 1.8 V minimum supply, and 10-bit ADC for measurement signal conditioning. The 512-byte SRAM holds sample buffers, and 7 KB Flash fits calibration tables plus measurement algorithms. PPS routes EUSART to a Bluetooth or LoRa module without requiring external glue logic, conserving board space and BOM cost.
推薦
LED Lighting Controllers
The PIC16F15244-E/SO works well in smart LED drivers, RGBW strips, and architectural fixtures where the MCU must generate two PWM channels, perform color-space math, and report status over EUSART/SPI. Intelligent Analog peripherals and the 10-bit ADC support temperature-fold-back and current-sense feedback for safety. The 32 MHz clock avoids flicker artifacts in dimming curves, and PPS simplifies routing when driver FETs sit far from the MCU.
推薦
Automotive Body and Comfort Electronics
Although not AEC-Q100 qualified, the PIC16F15244-E/SO is still useful for non-safety automotive body modules such as seat controllers, mirror adjusters, and interior lighting nodes during development and pre-production phases. Its -40 C to +125 C rating, PPS, and 2 PWM channels handle small DC-motor and LED loads reliably. For series production AEC-Q100 needs, the design should be ported to the automotive-grade PIC16F1xxx equivalent specified by Microchip's automotive team.

設計說明
Place a 100 nF decoupling capacitor as close as possible to VDD (pin 20), with a second 100 nF or 10 uF bulk capacitor at the board supply entry. Microchip's PIC16F15244 datasheet recommends a low-ESR ceramic bypass for the analog supply when ADC accuracy is required. For battery designs, gate analog peripherals off when not in use to leverage XLP SLEEP current in the nanoampere range.
Keep MCLR/VPP trace short and route it away from switching signals to avoid spurious resets. Use PPS early in the design to assign UART/SPI/I2C to convenient I/O pins, which lets you simplify routing for the SOIC-20 footprint. Follow Microchip's SOIC-20 wide-body land pattern recommendations (about 1.27 mm pitch) to maintain manufacturability at high assembly yield.
When using the 10-bit ADC, dedicate one AVdd/AVss pair if available, and add a small RC filter on the analog supply rail to reject switching noise from digital peripherals. Keep ADC traces away from PWM and CCP outputs to minimize coupled noise. PPS lets you reassign digital functions so ADC inputs can sit on quieter pins.
Do not assume the SOIC-20 narrow-body (SN) and wide-body (SO) packages share the same land pattern - they do not. Confirm thermal modeling for sustained 32 MHz operation; in enclosed enclosures, junction temperature can climb above ambient. Finally, verify your XC8 compiler version has a PIC16F15244 device header before firmware development begins.
