PIC16F15243-E/SO Descripción general
An 8-bit microcontroller (MCU) is a single-chip computer that integrates a CPU, non-volatile program memory (typically Flash), volatile working memory (RAM), and a set of on-chip peripherals into one package. PIC microcontrollers use a Harvard-architecture CPU with a RISC-like instruction set, separating program and data memory buses. Within Microchip's taxonomy, the PIC16F152xx belongs to the enhanced mid-range core family, positioned between the baseline PIC10/12/16 families and the high-performance PIC18 family, and tailored for cost-sensitive sensor and real-time control tasks.
Key features of the PIC16F15243 include 3.5 KB self-read/write Flash, 16 stack levels, two 10-bit PWMs, two Capture/Compare/PWM (CCP) modules, a Hardware Limit Timer (HLT), Watchdog Timer (WDT), PPS for flexible I/O mapping, EUSART (UART with LIN) and MSSP (SPI/I2C) communication, a 10-bit ADC with internal fixed-voltage reference, and eXtreme Low-Power Sleep mode. The 'E' suffix denotes an extended temperature grade of -40C to +125C.
The 20-pin SOIC package gives access to up to 18 general-purpose I/O pins via PPS, and the small outline footprint is suited for hand-soldered prototypes and high-density production boards alike. PPS allows most digital peripherals to be routed to almost any I/O pin, simplifying PCB layout and BOM reuse across the PIC16F152xx family. Combined with CIPs such as the Hardware Limit Timer, the device can service sensors, switches, and communication lines without CPU intervention, freeing the core for application logic.
Typical applications include low-power IoT sensor nodes, battery-powered remote controls, LED lighting controllers, white-goods and small-appliance control boards, and LIN-node automotive body electronics using the on-chip EUSART with LIN slave support. Designers value the XLP Sleep mode for multi-year coin-cell lifetimes and the PPS flexibility for layout reuse.
When designing with the PIC16F15243-E/SO, leave VDD/VSS decoupling within 5 mm of the pins, configure the Configuration Words for the desired oscillator and WDT behavior, and use PPS to keep high-speed signals (EUSART, MSSP) on adjacent pins to simplify routing. Verify ADC reference selection against the application noise budget, and ensure unused I/O pins are configured as outputs low to minimize Sleep current.

Aplicaciones típicas
PIC16F15243-E/SO es adecuado para 6 aplicacións: Battery-Powered IoT Sensor Node, LIN Slave Body Electronics Node, White-Goods and Small-Appliance Control Board, LED Lighting Controller, Remote Control and HMI Keypad, Industrial Sensor Front End.
Battery-Powered IoT Sensor Node
The PIC16F15243-E/SO suits coin-cell IoT sensors because its eXtreme Low-Power (XLP) Sleep holds RAM while drawing nanoamp-level quiescent current, extending multi-year battery life. The 10-bit ADC reads temperature, light, or motion sensors while the CPU is asleep, and the Hardware Limit Timer (HLT) plus PPS let the device wake on a sensor edge without CPU involvement. At 32 MHz active mode, a measurement-and-transmit duty cycle of <1% is realistic.
Recomendado
LIN Slave Body Electronics Node
The PIC16F15243-E/SO is a natural fit for automotive LIN slave body-electronics modules (window lifters, mirror controllers, seat switches). Its on-chip EUSART supports LIN slave protocol without external transceivers, PPS reassigns the LIN pin to any I/O, and the 10-bit ADC reads switch/wiper positions directly. The 'E' temperature suffix (-40C to +125C) covers cabin and under-hood environments typical of LIN nodes.
Recomendado
White-Goods and Small-Appliance Control Board
The PIC16F15243-E/SO integrates well into washing machines, dishwashers, and countertop appliances where a 32 MHz 8-bit core, 10-bit ADC for sensor readout, and dual PWM for motor or valve control replace a discrete analog front end. The Hardware Limit Timer (HLT) provides safety cutoffs independent of software, and PPS keeps the PCB layout clean even when board revisions relocate the AC zero-cross or triac pins.
Recomendado
LED Lighting Controller
For commercial and architectural LED drivers, the PIC16F15243-E/SO delivers 2x 10-bit PWM channels and 2x CCP modules that can drive constant-current LED strings via external MOSFETs, while the 10-bit ADC reads light sensors or current-sense amplifiers for closed-loop dimming. PPS keeps the analog and digital paths short, and XLP Sleep lets the fixture idle at microwatts when the lights are off.
Recomendado
Remote Control and HMI Keypad
The PIC16F15243-E/SO fits IR/RF remote controls and small human-machine interface keypads, where its XLP Sleep mode enables multi-year battery life, the EUSART drives an external RF transceiver for 433/868 MHz links, and PPS reassigns the keypad matrix to spare I/O without board re-spins. The 256 B RAM is sufficient for scan-debounce state and short RF payload buffers.
Recomendado
Industrial Sensor Front End
In factory-automation sensor front ends, the PIC16F15243-E/SO digitizes analog 4-20 mA or 0-10 V signals via its 10-bit ADC, gates a digital output via a CCP module, and reports state over SPI to a host PLC using the on-chip MSSP. The -40C to +125C extended temperature grade supports outdoor and cabinet-mounted industrial installations, while PPS keeps the analog and digital paths on separate pin groups.

Notas de diseño
Estimated: at 32 MHz active and 3.3 V VDD, the PIC16F15243-E/SO core draws roughly 4-6 mA in active mode. Decouple VDD/VSS with a 100 nF ceramic within 5 mm of the supply pins; add a bulk 1-10 uF if the supply is shared with RF or motor loads. To exploit XLP Sleep for battery applications, place the device in Sleep between measurements and wake from the Hardware Limit Timer (HLT) or a peripheral interrupt rather than from the Watchdog Timer alone.
Use the 20-pin SOIC land pattern recommended by Microchip (IPC-7351 nominal density). Provide a ground pour under the MCU and stitch vias around the perimeter to keep return paths short for the EUSART and MSSP lines. Keep the ICSP/ICD pins (RA0/ICDDAT, RA5/ICSCLK, RB6/ICSPCLK, RB7/ICSPDAT) routed to a 4-pin header or test pad cluster so debug and programming do not require board rework.
Do not leave the MCLR/RA3 pin floating - tie it to VDD through a 10 kohm resistor or drive it directly from the debugger. Unused I/O pins must be configured as outputs low (not inputs) to minimize Sleep current. When using the ADC, allow the internal reference the manufacturer-specified settling time after enabling, or first conversions will be inaccurate.
When routing EUSART (LIN/UART) and MSSP (SPI/I2C) traces, keep them short and adjacent where possible; the PIC16F15243-E/SO's Peripheral Pin Select (PPS) lets you remap these peripherals to convenient pins, so choose pin assignments that minimize trace crossings on the PCB. For SPI runs above 1 MHz, place a 33 ohm series resistor near the driver to dampen ringing on the SCK line.
