PIC16F15376-I/PT - 8-Bit 32MHz 28KB Flash MCU | Microchip
MPN: PIC16F15376-I/PT ✓ فعالPIC16F15376-I/PT نمای کلی
An 8-bit microcontroller (MCU) is a small computing system on a single integrated circuit containing a CPU, non-volatile program memory (Flash), volatile working memory (RAM), and programmable I/O peripherals. Within the embedded hierarchy, the PIC16F15376 belongs to the PIC16 family -> 8-bit MCU -> microcontroller -> embedded processor -> semiconductor. The 8-bit architecture remains widely adopted for cost-sensitive, deterministic, low-power applications where computational throughput requirements are modest but peripheral integration and ultra-low standby current are critical.
Key specifications include 28KB (16K x 14 words) of Flash, 2KB of RAM, four 10-bit PWM outputs, a 10-bit ADC with automatic accumulation, a 5-bit DAC, two Enhanced Universal Synchronous Asynchronous Receiver Transmitters (EUSART), SPI, and I2C communication peripherals. The device also integrates a Comparator, Complementary Waveform Generator (CWG), Zero-Cross Detection (ZCD), and a temperature indicator. XLP technology delivers typical sleep currents below 50 nA, enabling battery-powered designs with multi-year lifetimes.
The architecture uses a Harvard-style RISC core with a 14-bit instruction word and a single-cycle 32MHz oscillator block with internal HFINTOSC. Internal peripherals operate autonomously via Peripheral Pin Select (PPS) signal routing, allowing reassignment of peripheral functions to alternative pins without package changes. The 44-pin TQFP package exposes up to 36 GPIO pins, sufficient for sensor fusion, user-interface I/O, and display-driving applications.
Typical applications include IoT sensor nodes, home-appliance controls, low-energy wireless sensor platforms, LED lighting controllers, and battery-powered metering. The combination of Intelligent Analog (10-bit ADC, DAC, comparator) and CWG enables direct driving of power-conversion stages, including PFC and LLC converters. For designers, selecting the 'I' industrial temperature grade (-40C to +85C) ensures robust operation across commercial and industrial environments without additional qualification steps.

کاربردهای معمول
PIC16F15376-I/PT مناسب است برای 6 کاربردs: IoT Sensor Node, Home Appliance Control, LED Lighting Controller, Battery-Powered Metering, Power Conversion Stage Controller, Automotive Body Electronics.
IoT Sensor Node
The PIC16F15376-I/PT is well suited for IoT sensor nodes because its 8-bit PIC16 core combines a 32MHz HFINTOSC clock, 28KB Flash, and 2KB RAM with XLP sleep current typically below 50 nA. The Intelligent Analog block (10-bit ADC, 5-bit DAC, comparator) and Core Independent Peripherals (CIPs) operate autonomously without CPU intervention, allowing the CPU to remain in sleep until a sensor threshold is crossed. The 44-pin TQFP exposes up to 36 GPIO for multiple sensor channels, while EUSART/SPI/I2C with PPS supports LoRa, BLE, or Wi-Fi module links. Battery-powered designs achieve multi-year operation on a single Li-SOCl2 cell thanks to eXtreme Low-Power technology.
پیشنهادی
Home Appliance Control
The PIC16F15376-I/PT fits home appliance control boards (washing machines, dishwashers, microwave ovens, induction cooktops) because of its Complementary Waveform Generator (CWG) and Zero-Cross Detection (ZCD) for direct AC-line triac/SCR driving, plus four 10-bit PWM channels for variable-speed motor or heating-element control. The 28KB Flash accommodates state-machine and user-interface code, and the 10-bit ADC reads thermistor, current-sense, and mains-voltage signals. With Peripheral Pin Select (PPS) the same firmware can be reused across 28/40/48-pin package options, simplifying SKU consolidation. The 2.3V to 5.5V VDD range supports both 3.3V and 5V designs without level shifters.
پیشنهادی
LED Lighting Controller
The PIC16F15376-I/PT serves as a dimmable LED controller because the four 10-bit PWM outputs (extendable via PPS) drive constant-current LED strings across 0-100% dimming range without flicker, while the 5-bit DAC and 10-bit ADC support closed-loop current and color-temperature feedback. The CWG generates complementary drive signals for half-bridge LED topologies. XLP standby below 50 nA suits always-on smart-lighting hubs that must remain responsive over months of battery or energy-harvest-operation. Up to 36 GPIO on the TQFP (T) package handle multiple LED channels plus I2C/SPI control links to host microcontrollers or wireless modules.

Battery-Powered Metering
Battery-powered metering (gas, water, electricity, heat cost allocators) leverages the PIC16F15376-I/PT for its XLP sleep current below 50 nA, 32MHz HFINTOSC for fast wake-and-measure cycles, and 28KB Flash for advanced metering algorithms including tamper detection. The 10-bit ADC with automatic accumulation accurately measures low-frequency sensor signals from thermistors, flow sensors, or shunt resistors. The 2.3V minimum VDD allows direct operation from a single Li-SOCl2 cell across its full discharge curve, while industrial -40C to +85C operation supports outdoor installations. Up to 36 GPIO accommodate pulse-output, LCD, and tamper-switch interfaces.

Power Conversion Stage Controller
The PIC16F15376-I/PT works as a digital controller for low-power PFC, LLC, and flyback converters because its CWG generates dead-band-controlled complementary drive signals for MOSFET half-bridges while the 10-bit ADC samples current and voltage at high bandwidth. The 2KB RAM holds PID state and look-up tables for soft-start and adaptive dead-time control. The two EUSART modules support isolated digital communication to a system master, and SPI/I2C via PPS drive isolated gate-driver ICs. Compared with discrete analog implementations, this approach reduces BOM count and enables firmware-tunable loop compensation.

Automotive Body Electronics
Body-electronics modules (interior lighting, HVAC blowers, seat controllers, mirror adjusters) benefit from the PIC16F15376-I/PT 8-bit core with CWG for direct motor/relay drive, four 10-bit PWM channels for dimming and speed control, and the 10-bit ADC for sensor feedback. The industrial -40C to +85C temperature range suits under-dash installations; for harsher under-hood environments the AEC-Q100-qualified 'E' grade (-40C to +125C) variant is recommended. The 44-pin TQFP package meets automotive PCB-density targets and supports LIN bus via the EUSART module plus external LIN transceiver.

یادداشت‌های طراحی
Estimated: At VDD=5V and active mode drawing 4 mA at 32 MHz, power dissipation is roughly 20 mW. Adding a 0.1uF ceramic decoupling capacitor within 5 mm of the VDD pin and a bulk 10uF tantalum or ceramic on the board VDD trace reduces switching noise and prevents code-execution glitches. Connect both VDD pins (10 and 40 on the TQFP) and both VSS pins (9 and 39) to maintain supply integrity during high-current PWM events.
Estimated: The 44-pin TQFP (PT) 10x10mm package has a typical thermal resistance theta_JA around 50 C/W. At ambient 85C and 20 mW dissipation the junction rises only 1C, well within the -40C to +85C industrial range. However, in PWM-intensive motor-drive applications the CWG outputs can sink up to 25 mA per pin, increasing package dissipation. Spread thermal vias under the exposed die-attach pad (none on this package; use copper pour on top and bottom layers) to manage hot spots.
Estimated: When migrating from the PIC16F15376-I/P (40-pin PDIP) to the I/PT (44-pin TQFP), the additional RE0-RE3 and RF0-RF3 pins are NOT bonded out on the 40-pin variant. Code that uses these pins will fail to compile or run on the smaller package. Always configure pins as digital or analog with the ANSELx registers, since pins default to analog mode on reset. Use the Peripheral Pin Select (PPS) unlock sequence (write 0x55 to PPSLOCK, then 0xAA, then the configuration) before assigning peripheral functions to non-default pins.
The ICSP programming pins RB6 (ICSPCLK) and RB7 (ICSPDAT) must not be pulled low at power-up or the device may enter programming mode instead of running user code. Add 10k pull-up resistors to RB6/RB7 if external circuits can sink these lines. The MCLR reset pin (typically shared with RA5 or RB5 on this family) needs a 10k pull-up to VDD; if not used, configure it as a digital input with the WPU pull-up enabled.
