PIC16F1847T-I/MV - 8-Bit 32MHz 14KB Flash MCU | Microchip
MPN: PIC16F1847T-I/MV ✓ Hoạt độngPIC16F1847T-I/MV Tóm tắt
A microcontroller (MCU) is a single-chip computer that integrates a CPU, non-volatile program memory (Flash), volatile working memory (RAM), EEPROM for data retention, and a rich set of peripherals on one die. Within the product taxonomy, the PIC16F1847T-I/MV is a microcontroller -> 8-bit MCU -> enhanced mid-range core -> flash MCU -> power-efficient (XLP) MCU -> semiconductor. The 8-bit Harvard RISC architecture provides deterministic instruction execution for embedded control loops.
Key features include 32 MHz maximum CPU clock (8 MHz internal oscillator with 4x PLL), 14-bit instruction word, 16-level hardware stack, 12-bit ADC with computation (ADC2), 10-bit DAC, 8-/16-bit timers, ECCP, MSSP (I2C/SPI), EUSART, mTouch capacitive touch sensing, and nanoWatt XLP sleep currents as low as 20 nA. Integrated peripherals reduce BOM cost by eliminating external ADCs, op-amps, and touch front-end ICs.
The architecture uses a Harvard RISC core with separate program and data buses, a 16-level hardware stack with overflow/underflow reset, and an interrupt controller with automatic context saving. The XLP technology adds ultra-low-power sleep modes (Sleep, Idle, Doze) and peripheral module disable to minimise quiescent draw in battery-powered designs. The device operates across 2.5V to 5.5V with brown-out-reset and an internal voltage reference.
Typical applications include capacitive touch user interfaces (mTouch), battery-powered sensor nodes, LED lighting control, low-power IoT end nodes, and human-machine interface (HMI) panels. The compact UQFN-28 footprint makes it well suited to space-constrained wearables and consumer appliances where PCB area is at a premium.
When designing with this MCU, allocate a 0.1uF decoupling capacitor adjacent to each VDD pin and keep the trace from ICSPDAT/ICSPCLK to the programming header shorter than 5 cm to ensure reliable in-circuit serial programming. The 'T' suffix denotes Tape & Reel packaging; the 'I' suffix indicates the -40C to +85C industrial temperature grade, while '/MV' specifies the 28-pin UQFN 4x4 mm package.

Ứng dụng tiêu biểu
PIC16F1847T-I/MV phù hợp cho 6 Áp dụngs: Capacitive Touch User Interface, Battery-Powered Wireless Sensor Node, LED Lighting Control, Home Appliance Control Board, Industrial HMI Panel, IoT Edge Sensor Aggregator.
Capacitive Touch User Interface
The PIC16F1847T-I/MV's integrated mTouch peripheral with up to 16 capacitive-sensing channels supports robust touch buttons, sliders, and proximity sensors in appliance and consumer-electronics HMIs. Its Charge Time Measurement Unit (CTMU) provides noise-immune sensing, while XLP nanoWatt technology keeps sleep current below 20 nA so battery-powered remotes and panels can run for years on a single coin cell. The 28-pin UQFN 4x4 mm package fits behind a glass or plastic overlay, leaving board area for the power supply and wireless module.
Được đề xuất
Battery-Powered Wireless Sensor Node
With XLP nanoWatt sleep currents as low as 20 nA, the PIC16F1847T-I/MV excels as the host MCU for sub-1 GHz or BLE sensor endpoints reporting temperature, humidity, or occupancy. The 32 MHz core wakes in microseconds to service ADC2 conversions, encrypt payloads, and transmit via SPI-attached radios before returning to deep sleep. The 256 B EEPROM stores calibration constants without wearing Flash, and the 2.5V to 5.5V supply range allows direct connection to a single Li-ion or two AA cells without LDO overhead.
Được đề xuất
LED Lighting Control
The PIC16F1847T-I/MV drives multi-channel LED fixtures using its ECCP/CCP PWM modules with up to 10-bit resolution, supporting smooth dimming and colour-mixing across RGBA or tunable-white arrays. The 12-bit ADC2 with computation enables closed-loop current sensing for constant-luminance output without an external op-amp, while the 10-bit DAC can drive an analog reference for warm-dim curves. UQFN-28 4x4 mm packaging is small enough to integrate into MR16 bulbs, downlights, and strip-light controllers.
Được đề xuất
Home Appliance Control Board
In washing machines, dishwashers, and coffee makers, the PIC16F1847T-I/MV serves as the main user-interface and motor-control MCU, replacing multiple discrete timers and op-amps. Its EUSART links to a Wi-Fi or BLE module for smart-appliance connectivity, the MSSP drives I2C sensors, and the ECCP module generates triac-firing pulses for AC load control. The 14 KB Flash accommodates state-machine firmware plus a USB-CDC bootloader for field updates, all within the 28-pin UQFN footprint.
Được đề xuất
Industrial HMI Panel
The PIC16F1847T-I/MV drives small graphical or segment LCDs via its mTouch buttons and PWM backlight control, replacing mechanical keypads in factory-floor controllers. The 12-bit ADC with computation monitors 4-20 mA loops or thermistor inputs without external conditioning, while the EUSART provides Modbus RTU communication with PLCs. The industrial -40C to +85C temperature grade and wide 2.5V to 5.5V supply tolerance suit harsh control-cabinet environments.
Được đề xuất
IoT Edge Sensor Aggregator
As an edge aggregator in IoT nodes, the PIC16F1847T-I/MV collects data from multiple I2C sensors (temperature, pressure, accelerometer) and forwards pre-processed packets to a host MCU or gateway over UART/SPI. The 14 KB Flash holds MQTT-SN or LoRaWAN stacks, the 1 KB RAM buffers sensor frames, and the XLP sleep modes allow duty-cycled operation on energy-harvested power. The compact UQFN-28 package enables dense sensor-array layouts on small PCBs.

Ghi chú thiết kế
Place a 0.1uF decoupling capacitor adjacent to each VDD pin (pins 10 and 16 on the UQFN-28 package) and a single 10uF bulk capacitor on the supply rail. For battery-powered designs using XLP sleep modes, the MCP1700 LDO provides a 1.6uA quiescent regulator that preserves nanoWatt sleep performance better than higher-Iq alternatives.
Keep ICSPDAT (RB4) and ICSPCLK (RB6) traces shorter than 5 cm and route them away from switching power nodes to ensure reliable in-circuit serial programming. The UQFN-28 exposed thermal pad must be soldered to a copper pour connected to VSS to meet thermal and mechanical reliability targets; do not leave it floating.
Pin 3 on the UQFN-28 PIC16F1847T-I/MV is dual-function RA3/MCLR. To use the device's internal MCLR disable feature for clean resets, configure the Configuration Word (CONFIG_MCLRE = OFF) before code development. Avoid omitting the 1kohm pull-up on MCLR when MCLR is enabled, otherwise the device can enter programming mode intermittently on noisy power rails.
For capacitive-touch sensing, dedicate adjacent ground copper around the touch electrodes and route the CTMU charge-discharge trace as a short, guarded track. Avoid running switching signals (PWM, SPI clock) within 3 mm of touch sensors to prevent false triggers. Microchip's AN1258 application note provides reference layouts for slider and button patterns.
