PIC16F15274-E/P Présentation
A microcontroller (MCU) is a compact integrated circuit containing a processor core, memory, and programmable input/output peripherals. The PIC16F15274 belongs to the 8-bit microcontroller category, which sits below 16-bit and 32-bit MCUs in computational capacity but excels in simplicity, deterministic timing, and ultra-low power operation. Within the broader taxonomy, an MCU is a type of embedded processor -> microcontroller -> semiconductor -> integrated circuit. The PIC architecture is a RISC design known for its small instruction set, low power consumption, and robust peripherals.
Key differentiating features include the Peripheral Pin Select (PPS) which allows flexible remapping of digital peripherals to any I/O pin, reducing PCB layout constraints. The 10-bit ADC with computation (ADC²) performs hardware averaging, threshold comparison, and basic filtering, offloading tasks from the CPU. The XLP technology delivers nanoWatt sleep currents, enabling battery-powered applications to run for years on a single cell.
The PIC16F15274 utilizes the enhanced mid-range PIC16 CPU core with a modified Harvard architecture, providing deterministic 8-bit instruction execution. The integrated Core Independent Peripherals (CIPs) like the Hardware Limit Timer (HLT) and PWM allow complex control sequences to execute without CPU intervention, freeing the CPU for application logic. The wide operating voltage range from 1.8V to 5.5V supports both 3.3V and 5V system designs.
Typical applications include IoT sensor nodes, home appliance control, LED lighting, battery management, industrial automation, and low-power edge devices. The combination of XLP technology and flexible peripherals makes it ideal for any application demanding low standby current and reliable real-time control.
When designing with this device, ensure proper decoupling with 100nF ceramic capacitors placed close to VDD pins, and consider using PPS to route peripherals away from analog-sensitive pins. The 40-pin PDIP package offers easy through-hole assembly, simplifying prototyping and hobbyist projects.

Applications typiques
PIC16F15274-E/P convient pour 6 applications: IoT Wireless Sensor Node, Home Appliance Control, LED Lighting Driver, Battery Management Unit, Industrial Sensor Transmitter, Low-Power Edge Device Controller.
IoT Wireless Sensor Node
The PIC16F15274-E/P's XLP nanoWatt Sleep current and Peripheral Pin Select make it ideal for battery-powered IoT sensor endpoints. With 32 MHz CPU headroom, 10-bit ADC with computation, and 512 B SRAM, the device handles sensor sampling, local averaging, and threshold checks before waking the host to transmit. Place a 100nF ceramic bypass close to VDD, use PPS to keep the radio's SPI away from the analog ADC inputs, and exploit HLT to time-stamp events without CPU intervention.
Recommandé
Home Appliance Control
The PIC16F15274-E/P's 2x PWM, 2x CCP, and 36 I/O pins give enough headroom for HVAC, washing-machine, and kitchen-appliance control boards. The 10-bit ADC with computation provides hardware averaging for motor current sensing, while the EUSART drives the user-interface display. The 40-pin PDIP package simplifies through-hole assembly and field serviceability, and the extended -40C to +125C temperature range supports appliance environments.
Recommandé
LED Lighting Driver
With 2 hardware PWM channels and the Hardware Limit Timer (HLT), the PIC16F15274-E/P drives multi-channel LED dimming without CPU cycles. Its 1.8V-5.5V input range allows direct operation from a buck-boost supply, while PPS keeps the PWM outputs away from ADC noise. The XLP Sleep mode lets standby lighting controllers meet ENERGY STAR standby budgets while keeping the PWM engine ready to resume within microseconds.
Recommandé
Battery Management Unit
The PIC16F15274-E/P's 10-bit ADC with computation monitors cell voltage, current, and temperature for low-cell-count battery packs. Its nanoWatt Sleep current minimizes quiescent drain while the CPU is off between samples, and the CCP/PWM channels can drive balancing FETs. The 40-pin PDIP format eases bench prototyping of battery management prototypes that can later migrate to QFN variants in the same family.
Recommandé
Industrial Sensor Transmitter
The PIC16F15274-E/P is well-suited to 4-20 mA loop-powered and industrial field sensors, where its extended temperature range, EUSART for RS-485 comms, and ADC with computation deliver robust measurement under harsh conditions. PPS allows the EUSART and SPI to coexist on the same board without re-routing, while the HLT and WDT provide fail-safe supervision required in industrial safety applications.
Recommandé
Low-Power Edge Device Controller
Edge devices performing local analytics and housekeeping benefit from the PIC16F15274-E/P's combination of ADC computation, HLT, PPS, and XLP Sleep. The 32 MHz CPU delivers enough headroom for sensor fusion, while Sleep currents under 100 nA let the device wake only when something interesting happens. The 40-pin PDIP simplifies breadboarding, and the SPI/I2C peripherals let it manage small companion radios or sensors.

Principaux différenciateurs
- Newest family member with 10-bit ADC with computation (vs PIC16F15243-E/P)
- Peripheral Pin Select (PPS) for flexible PCB routing (vs PIC16F15243-E/P)
- Higher-memory variants available in same package (vs PIC16F15273-E/P)
Notes de conception
Place a 100nF ceramic decoupling capacitor within 5 mm of each VDD pin (pins 9 and 36 on the 40-pin PDIP). For designs where the ADC is active, add a 10uF bulk capacitor near the MCU to suppress voltage dips caused by digital switching. The 1.8V-5.5V input range allows direct connection to a single Li-Ion cell with no LDO, but ensure VDD never exceeds 5.5V including load-dump transients.
Use the Peripheral Pin Select (PPS) feature to route noisy digital peripherals (PWM, SPI) away from analog ADC inputs. Keep ADC traces short and guarded by a ground ring to minimize digital-to-analog crosstalk. The 40-pin PDIP gives ample board space, but maintain a low-impedance ground plane to keep the XLP Sleep current noise floor low.
Do not leave the MCLR pin floating - tie it to VDD through a 10k resistor for normal operation, or directly to VDD if reset is not required. The ICSP programming pins (PGD/PGC) must be accessible via test points or a header for in-circuit programming. When migrating from the older PIC16F15243-E/P, verify PPS mapping because the newer PIC16F15274-E/P may have different default peripheral assignments.
