PIC16F15276-E/PT 개요
A microcontroller (MCU) is a single-chip computer containing a processor core, program memory, data memory, and integrated peripherals such as ADCs, timers, and communication interfaces. The PIC16F15276 belongs to Microchip's PIC16 mid-range 8-bit MCU family, which sits between the PIC10/12/16 baseline series and the PIC18 enhanced series in the company's taxonomy. Within the power-management hierarchy, this device performs digital control of sensors and actuators rather than power conversion itself.
Key features include 32MHz maximum CPU clock (8 MIPS instruction throughput), 28KB Flash self-programmable program memory, 2KB data SRAM, 10-bit ADC with up to 28 input channels, two 10-bit PWMs, two CCP modules, and standard serial interfaces including EUSART, SPI, and I2C. Peripheral Pin Select (PPS) allows flexible signal routing, and the Hardware Limit Timer (HLT) simplifies safety-critical timing.
The PIC16F15276 architecture uses a Harvard RISC core with single-cycle instructions, achieving deterministic 125ns instruction execution at 32MHz. Intelligent Analog peripherals operate without CPU intervention, reducing software complexity. The XLP technology delivers nanoWatt sleep currents, enabling battery-powered applications with multi-year lifetimes.
Typical applications include industrial sensor interfaces, IoT edge nodes, building automation, low-power wireless sensor hubs, home appliance control, and battery-powered measurement instruments. The 10-bit ADC and PWM channels simplify motor and lighting control loops.
Designers should consider the device's 1.8V to 5.5V supply range when integrating with sensors or 3.3V/5V logic. PPS flexibility requires careful pin-map planning in MPLAB X IDE to avoid signal conflicts, and the -E temperature grade suits automotive under-hood and industrial environments.

주요 차별점
- 28 KB Flash with 2 KB SRAM in 44-pin TQFP at competitive price point (vs PIC16F15274-E/PT)
- Lower cost than PIC16F15376-I/PT for applications fitting 28 KB (vs PIC16F15376-I/PT)

설계 노트
Estimated: At 32MHz active CPU with all peripherals enabled, the PIC16F15276-E/PT typically draws 6-8 mA from a 3.3V supply. In Sleep mode with XLP enabled, quiescent current drops below 100nA, enabling multi-year battery operation from a CR2032 coin cell. Use the LFINTOSC (31 kHz internal oscillator) for Sleep and switch to HFINTOSC only when CPU processing is required. Decouple VDD with 100nF and 10uF capacitors placed within 5mm of each VDD pin.
PPS remapping requires explicit unlock sequence (PPSLOCK bit) before configuration writes. Forgetting this sequence causes the PPS registers to appear read-only and silently disables peripheral routing. Always consult the latest PIC16F15276 datasheet pinout diagram for the 44-pin TQFP package - the same peripheral pin is not always available on every package pin, especially across the PIC16F15256/74/75/76 family variants.
Estimated: The 44-pin TQFP (PT) package has a thermal resistance (theta_JA) of approximately 50 C/W on a standard 4-layer JEDEC test PCB. At full 32MHz CPU load and 5V supply, total power dissipation is approximately 40 mW, yielding a junction temperature rise of 2C above ambient - well within the -40C to +125C operating range. Industrial and automotive customers should still validate thermals with their actual PCB layout and enclosure.
규정 준수 정보
RoHS and lead-free per Microchip product page and DigiKey listing. The -E temperature grade (-40C to +125C) is suitable for industrial but is not AEC-Q100 automotive-qualified; for AEC-Q100 applications, use PIC16F15276-E/PT variants designated for automotive or consult Microchip directly.
