PIC16F15385T-I/MV - 8-bit MCU, 14KB Flash, 48-UQFN | Microchip
MPN: PIC16F15385T-I/MV ✓ Hoạt độngPIC16F15385T-I/MV Tóm tắt
An 8-bit PIC microcontroller is a RISC-based embedded processor that combines a CPU, RAM, Flash, and configurable peripherals on a single die. PIC MCUs sit within the broader microcontrollers (MCU) category, which itself belongs to the embedded IC / semiconductor hierarchy. They are designed for deterministic, low-power, low-cost control tasks. The PIC16F15385T-I/MV specifically belongs to the full-featured 28/40/44/48-pin sub-tier of the PIC16F153XX family, distinguished by the highest peripheral density in the series.
Key features include 4 PWM modules, a 5-bit DAC, comparators, a Configurable Logic Cell (CLC) block (4 instances), a Complementary Waveform Generator (CWG), 2 EUSART, SPI, and I2C communication peripherals, plus Core Independent Peripherals (CIPs) that offload tasks from the CPU. The integrated 10-bit ADC with Intelligent Analog capability eliminates many external analog components, while the XLP nanoWatt technology enables battery-powered applications with sleep currents measured in nanoamperes.
Architecturally, the device uses a 14-bit instruction word with a modified Harvard architecture, providing predictable instruction timing and tight C code generation through Microchip's XC8 compiler. The 32MHz internal oscillator and the form-factor-matched pinout (48-UQFN with exposed pad for thermal dissipation) make it suitable for compact industrial designs.
Typical applications include IoT sensor nodes, industrial control interfaces, low-power wireless sensor hubs, consumer appliance control boards, LED lighting controllers, and battery-powered instrumentation. The combination of CIPs and XLP enables designs where the CPU sleeps most of the time and peripherals autonomously service interrupts.
Designers should note that the 48-UQFN package requires careful PCB layout with a thermal pad connected to ground for proper heat dissipation, and the exposed pad must be soldered for mechanical reliability. Use MPLAB X IDE with the XC8 compiler for development, and choose PIC16F15386 for higher pin count or PIC16F15376 for cost-down variants in the same family.

Ứng dụng tiêu biểu
PIC16F15385T-I/MV phù hợp cho 7 Áp dụngs: IoT Sensor Nodes, Industrial Control Interfaces, Battery-Powered Instrumentation, LED Lighting Controllers, Consumer Appliance Control Boards, Low-Power Wireless Sensor Hubs, Automotive Body Electronics (Sub-System).
IoT Sensor Nodes
The PIC16F15385T-I/MV's 14 KB Flash and 1 KB RAM combined with XLP nanoWatt sleep currents in the nA range make it ideal for battery-powered IoT sensor nodes that wake periodically to take a measurement and transmit via SPI/I2C-connected radio. The integrated 10-bit ADC with Intelligent Analog and 4 CLC blocks service sensor signal conditioning without waking the CPU, while 2 EUSART channels support concurrent sensor and radio links. With 32 MHz CPU speed and 44 I/O pins, this MCU can drive multiple sensors in a single node and remains pin-compatible with higher-memory family members for future-proofing.

Industrial Control Interfaces
The PIC16F15385T-I/MV delivers deterministic 8-bit RISC performance with 32 MHz operation, 2.3-5.5 V wide supply tolerance, and the -40C to +85C industrial temperature range required for factory-floor PLC interfaces and HMI control boards. Its 4 PWM modules drive motor or valve actuators, while 2 EUSART channels handle Modbus master/slave links simultaneously. CIPs like CWG and CLC offload safety interlocks and timing sequences from the CPU, enabling responsive control loops. The 48-UQFN package fits compact DIN-rail-mount modules while the exposed pad handles continuous 32 MHz operation without thermal throttling.

Battery-Powered Instrumentation
The PIC16F15385T-I/MV's XLP technology achieves nanoampere sleep currents, making it ideal for handheld multimeters, portable data loggers, and field instruments where battery life drives the user experience. The 10-bit ADC with Intelligent Analog performs ratiometric measurements against the supply voltage, eliminating the need for a precision reference in many cases. The 5-bit DAC, comparators, and CLC blocks implement fast over-current or under-voltage detection autonomously. Designers can leverage PIC16F153XX family migration paths to upgrade memory or pin count without changing PCB layout when a product line expands.

LED Lighting Controllers
The PIC16F15385T-I/MV provides 4 PWM channels and a Complementary Waveform Generator (CWG) with programmable dead-band control, ideal for driving high-brightness LED arrays with smooth dimming and color-mixing. Its 32 MHz clock supports high-frequency PWM to avoid audible flicker, while CLC blocks implement closed-loop current feedback without CPU intervention. With 44 I/O pins, the MCU handles multiple LED strings plus user-interface inputs (buttons, rotary encoders via EUSART/SPI). Low sleep current allows always-on standby operation in smart lighting fixtures where energy consumption in off-state is regulated.

Consumer Appliance Control Boards
The PIC16F15385T-I/MV is well-suited to white-goods appliance control - washing machines, dishwashers, coffee makers, and air purifiers - where its 2.3-5.5 V range accepts rectified mains supplies and its integrated peripherals reduce BOM. The 4 PWMs drive motors and solenoids, comparators monitor water level or temperature sensors, and the EUSART connects to user-interface displays or BLE modules. PIC16F153XX CIPs implement safety interlocks and timing sequences in hardware, reducing firmware certification burden for IEC 62138 safety standards.
Được đề xuất
Low-Power Wireless Sensor Hubs
The PIC16F15385T-I/MV acts as a sensor-hub MCU that aggregates data from SPI/I2C-connected environmental sensors and forwards it over UART/SPI to a wireless radio (LoRa, Sub-GHz, BLE module). Its dual EUSART allows simultaneous wired debug connection and radio communication, while the 14 KB Flash holds sensor-fusion and scheduling firmware. XLP nanoWatt sleep currents measured in hundreds of nanoamperes enable multi-year battery life in remote deployments, and the wide 2.3-5.5 V input range accepts a variety of battery chemistries including LiSOCl2 primary cells.

Automotive Body Electronics (Sub-System)
The PIC16F15385T-I/MV's industrial -40C to +85C range and robust peripheral set suit non-safety automotive body modules such as interior lighting controllers, mirror adjusters, and seat-position memories. The 4 PWM channels control LED ambient lighting, the CWG drives small motor H-bridges, and the wide 5.5 V tolerance handles 12 V vehicle rails after a small pre-regulator. Designers who need AEC-Q100 grade should consider the automotive-qualified PIC16F15385-E/MV equivalent or Microchip's dedicated automotive MCU families; this part itself is industrial grade, not automotive grade.

Ghi chú thiết kế
The 48-UQFN (6x6 mm) package includes an exposed thermal pad on the underside that MUST be soldered to the PCB ground plane. This pad provides both the primary heat-dissipation path and mechanical reliability under vibration. At maximum 32 MHz continuous operation across the industrial temperature range, expect junction-to-ambient thermal resistance theta_JA in the 30-40 C/W range - well within safe limits, but only if the exposed pad has at least 4-6 thermal vias to inner ground planes. Estimated: thermal dissipation at full 32 MHz core is below 30 mW, so passive PCB cooling is sufficient; no external heatsink is required.
Place the device with all four decoupling capacitors (typically 100 nF ceramic + 1 uF ceramic per VDD pin pair) within 2 mm of their respective VDD pins, with vias to a solid ground plane immediately beneath. Keep clock traces short, and place the 32.768 kHz crystal (if used for low-power RTC) within 5 mm of the SOSC pins to minimize noise pickup. The ICSP programming pins (RB6/RB7) should be accessible even in production layouts for in-system firmware updates.
Do not assume the 48-UQFN footprint is interchangeable with other PIC16F153XX packages - the pinout of the 48-UQFN differs from 44-QFN (ML), 40-DIP, and 28-pin variants. Forgetting to solder the exposed thermal pad causes the device to overheat and fail prematurely under sustained load. Programming voltage on MCLR must respect the 13.5 V max for high-voltage ICSP; using 5 V ICSP via the LVP configuration avoids this constraint entirely but requires the LVP pin to be left in a specific state on reset.
