PIC16F15243-E/P 개요
A microcontroller (MCU) is a single-chip computer that combines a CPU core, non-volatile program memory, RAM, and a set of on-chip peripherals such as timers, ADCs, and communication interfaces. PIC microcontrollers use a RISC-based Harvard architecture; the PIC16F152xx family extends the enhanced mid-range core with 49 instructions, 16 stack levels, peripheral pin select (PPS) remapping, and a functional-safety-capable design pattern. The PIC16F15243-E/P specifically targets applications that need this baseline at minimum cost.
Key features include one 10-bit ADC, two PWM channels, two CCP modules, hardware limiting timer (HLT), windowed watchdog timer (WDT), PPS, EUSART, and MSSP supporting SPI/I2C. The wide 1.8V-5.5V supply range permits direct operation from a single Li-ion cell or 5V regulated rail, while XLP sleep enables nanoWatt standby for battery-backed nodes.
The device uses an enhanced mid-range 8-bit core with self-programmable Flash, ICD debugging support, and a vectored interrupt controller. Compared with the older PIC16F1xx baseline, the 15243 adds PPS routing, an on-chip 32 MHz HFINTOSC with hardware limiting, and faster ADC acquisition, reducing external component count in sensor and motor-control designs.
Typical applications include consumer appliance control, low-cost sensor nodes, LED lighting controllers, battery-powered IoT edge devices, and PIC16F45 pin-compatible upgrades. Industrial segments include HVAC auxiliary controllers and simple human-machine interface boards that do not require USB or CAN.
When designing with the PIC16F15243-E/P, ensure MPLAB X IDE and XC8 compiler are used, allocate at least one PPS pin for serial debug, and respect the 5.5V absolute-maximum VDD limit. Decouple VDD with 100nF plus 10uF bulk capacitance placed within 5 mm of the supply pin.

일반적인 애플리케이션
PIC16F15243-E/P 적합 용도: 6 애플리케이션s: Consumer Appliance Control, Battery-Powered IoT Sensor Node, LED Lighting Controller, HVAC Auxiliary Controller, Low-Cost Human-Machine Interface, Functional Safety (FuSa) Subsystem.
Consumer Appliance Control
The PIC16F15243-E/P fits consumer appliance control (small kitchen, white-goods sub-modules) because it integrates 2 PWM and 2 CCP channels sufficient to drive a brushed motor, triac, or relay while running a small UI task loop. With 3.5 KB Flash and 256 B SRAM it hosts a foreground/background scheduler plus a UART command parser for the appliance bus. The 1.8-5.5 V supply range lets it share a 3.3 V or 5 V rail with the main SoC, and the XLP nanoWatt sleep drops quiescent current for Energy-Star standby compliance. PPS reassigns EUSART to free pins, easing single-layer PCB layouts where front-panel connectors are far from the MCU. Estimated: a 4-relay / 2-indicator design fits in roughly 60% of Flash with XC8 -pro optimization.

Battery-Powered IoT Sensor Node
For battery-powered IoT sensor nodes, the PIC16F15243-E/P combines XLP eXtreme Low-Power Sleep with a 10-bit ADC and an MSSP capable of SPI/I2C sensor polling, all in a 20-pin PDIP for hand-solderable prototypes. The 32 MHz HFINTOSC wakes the MCU in microseconds, executes a sensor read, transmits via EUSART or SPI, and re-enters sleep with brown-out reset protection. Estimated standby current of <100 nA at 2 V VDD extends CR2032 lifetime past one year at hourly wake. PPS remaps the SPI bus to free GPIOs so multiple sensor breakouts share one PCB footprint without wire rework.
추천
LED Lighting Controller
In LED lighting controllers, the PIC16F15243-E/P delivers 2 PWM channels and a 10-bit ADC suitable for closed-loop current or color-temperature control of constant-current LED strings. Running from a 5 V or 12 V post-regulator rail, the MCU reads a photodiode or NTC thermistor via ADC, adjusts PWM duty, and reports status over UART or DALI bridge. The 32 MHz instruction rate keeps PWM resolution high at low frequency for flicker-free dimming. XLP sleep is useful for off-state standby per Energy Star and EU ecodesign standby targets. The wide -40C to +125C extended operating range supports outdoor luminaires.
추천
HVAC Auxiliary Controller
For HVAC auxiliary controllers (fan-speed boards, damper actuators, zone sensors), the PIC16F15243-E/P provides EUSART for BACnet MS/TP or Modbus slave communication, plus MSSP for local I2C sensor expansion. The MSSP/I2C can host temperature, humidity, and pressure sensors while the EUSART exposes the board to a building automation controller. XLP sleep combined with windowed WDT enables robust unattended operation. PPS routing simplifies board layout by relocating the EUSART TX/RX to convenient header pins. The -40C to +125C temperature grade matches rooftop or basement equipment environments.
추천
Low-Cost Human-Machine Interface
For simple human-machine interface boards (keypads, encoder + LCD sub-boards), the PIC16F15243-E/P reads up to 14 GPIOs with interrupt-on-change support, drives an LCD or LED bar via PWM, and exposes EUSART to a host controller. PPS lets the designer place UART pins on any free I/O to simplify the front-panel flex routing. The enhanced mid-range core supports a small event-driven UI without an RTOS, and 256 B SRAM holds button debounce state and a small display buffer. The 20-pin PDIP is breadboard-friendly for prototype iteration before moving to an SOIC or QFN in volume.
추천
Functional Safety (FuSa) Subsystem
The PIC16F15243 belongs to Microchip's PIC16F152xx functional safety (FuSa) family, suitable for safety-related sub-systems requiring documentation, lockable Flash, and watchdog supervision. The hardware limiting timer (HLT) and windowed WDT enable independent channel supervision of a primary MCU, while PPS and EUSART route fail-safe telemetry to the host. This makes the part a good fit for low-cost safety islands in appliance, motor-control, and medical-class II devices where redundant supervision is required but cost ceiling is tight.

설계 노트
Decouple VDD (pin 1) with a 100 nF X7R ceramic placed within 5 mm of the pin plus a bulk 10 uF aluminum-polymer or ceramic on the same rail. The PIC16F15243-E/P has a 1.8-5.5 V supply window; do not exceed 5.5 V or device latch-up may occur. Estimated: at 32 MHz CPU + active ADC + EUSART, average IDD is roughly 4 mA, so a 10 uF bulk supports >2 ms of transient headroom without sagging.
Route ICSPDAT/ICSPCLK to RB6/RB7 as a 2-pin header for in-circuit serial programming, even on production boards, to allow field firmware updates and debug. Use PPS to remap EUSART TX/RX away from RB6/RB7 to free the ICSP pins. Place the MCLR pull-up (typically 10 kohm) close to pin 4 and avoid long traces that pick up ESD.
PPS allows remapping of digital peripherals to almost any I/O. When using I2C on RB6/RB7, enable the internal weak pull-ups only for low-speed (<100 kHz) buses; for 400 kHz Fast-Mode, use external 2.2-4.7 kohm pull-ups to meet rise-time spec. Place I2C pull-ups within 50 mm of the MCU to avoid ringing.
Do not leave MCLR floating - tie it to VDD through a 10 kohm resistor or drive it actively. The PIC16F15243-E/P has only 3.5 KB Flash; budget ~600 bytes for the XC8 runtime + interrupt vector table, leaving ~2.9 KB for application code. Enable the windowed WDT in long-running unattended designs to recover from stuck firmware states.
