MPN： PIC16F1783T-I/MV ✓ 啟用中PIC16F1783T-I/MV 概覽
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory (Flash/ROM), data memory (RAM), non-volatile data storage (EEPROM), and a rich set of peripheral blocks. The PIC16F1783 family sits in Microchip's enhanced mid-range (XLP™) portfolio, marketed as a low-power, mixed-signal part for sensor conditioning and analog front-end applications. Conceptually the part is a hybrid of a CMOS RISC microcontroller (programmable state machine), an analog front-end (12-bit ADC, 8-bit DAC, on-chip op-amp), and a digital signal controller (PSMC peripheral for power-converter control).
Key differentiating specifications include three operational 12-bit ADC modules with up to 14 channels, an 8-bit DAC, two on-chip operational amplifiers, a Power Supply Modulation Controller (PSMC), and an integrated temperature indicator. The chip supports EUSART with auto-baud, I2C/SPI, and up to four CCP/PWM channels. nanoWattMillis XLP™ technology provides sub-µA sleep currents for battery-powered sensor nodes.
The architecture is built around a Harvard RISC core with a 14-bit instruction word, 200 ns instruction execution, and a hardware multiplier. On-chip peripherals are mapped to I/O via Peripheral Pin Select (PPS), which simplifies PCB routing on the small 4x4 mm UQFN.
Typical applications include IoT sensor hubs, smart battery management, industrial sensor signal conditioning, lighting ballast control, and small BLDC/PMSM motor drives. The wide analog integration suits industrial 4-20 mA loop transmitters and medical/clinical instrument front-ends.
When designing with this part, observe Microchip's UQFN-28 land-pattern guidelines for the exposed thermal pad - it must be soldered to a ground pour for thermal dissipation and electrical reference. Use MPLAB® X IDE and the XC8 compiler for firmware development.

典型應用
PIC16F1783T-I/MV 適用於 7 應用s: IoT Battery-Powered Sensor Hubs, Industrial 4-20 mA Loop Transmitter, Lighting Ballast and LED Driver Control, Small BLDC / PMSM Motor Drive, Medical/Clinical Sensor Front-Ends, Switched-Mode Power Supply (SMPS) Controller, Industrial Sensor Signal Conditioning.
IoT Battery-Powered Sensor Hubs
The PIC16F1783T-I/MV's nanoWattMillis XLP™ sleep currents below 1 µA and 2.5-5.5 V supply make it ideal for wireless sensor nodes that spend most of their life in sleep. Its 12-bit triple ADC samples temperature, humidity, and battery voltage in a single wake-up cycle, while the 7 KB Flash holds full Microchip MiWi™ or BLE-through-AT-command firmware. The 32 MHz core executes edge-triggered logic in 200 ns, so interrupt response remains predictable. Engineers typically pair this MCU with an RN4870 Bluetooth module; the UQFN-28 4x4 mm footprint keeps the entire sensor hub under 1 cm².

Industrial 4-20 mA Loop Transmitter
The PIC16F1783T-I/MV's two on-chip op-amps configured as PGAs and its 12-bit ADC digitize RTD or thermocouple signals for a 4-20 mA loop transmitter. The PSMC peripheral generates the loop-side switching waveform, while the 8-bit DAC produces the analog output current reference. Wide 2.5-5.5 V operation tolerates compliance-voltage sag at high loads, and the 256 B EEPROM stores factory calibration data. The 28-UQFN 4x4 mm package fits inside a DIN-43760 head-mounted transmitter housing, with the exposed pad dissipating the 3.3 mA loop return heat.
推薦
Lighting Ballast and LED Driver Control
The PSMC peripheral and CCP/ECCP PWM modules make the PIC16F1783T-I/MV an excellent control core for dimmable LED ballasts and fluorescent lamp ballasts. Its 32 MHz core executes digital control loops in microseconds while the 12-bit ADC samples the inductor current for valley-fill or PFC correction. The on-chip op-amp functions as a transconductance amplifier for the current-sense path, eliminating an external TL072-type IC. The industrial -40 to +85 °C range covers the thermal envelope inside a sealed luminaire, and the 4x4 mm UQFN fits next to the switching FET on a 50 mm lighting PCB.
推薦
Small BLDC / PMSM Motor Drive
Sensorless BLDC or PMSM commutation runs on the PIC16F1783T-I/MV thanks to its PSMC plus CCP/EUSART peripherals. The on-chip comparators implement zero-cross back-EMF detection, while the 12-bit ADC reads the phase currents at the PWM midpoint. The 32 MHz instruction rate closes a sensorless start-up sequence under 50 ms, suitable for small pump and fan drives. The 28-UQFN 4x4 mm footprint keeps the control section compact when paired with gate-driver FETs in DPAK packages.
推薦
Medical/Clinical Sensor Front-Ends
The PIC16F1783T-I/MV's two on-chip op-amps plus 12-bit ADC form a complete analog front-end for clinical sensors such as pulse oximeters, glucometers, and small spirometers. The wide 2.5-5.5 V supply runs directly from 2x AAA cells, and XLP™ sleep currents below 1 µA keep the shelf-life competitive. The 256 B EEPROM records calibration coefficients per device, and the PSMC block generates a low-EMI bias voltage for the optical sensor. The 28-UQFN 4x4 mm footprint allows the entire front-end to occupy a wrist-bare pastille PCB area.
推薦
Switched-Mode Power Supply (SMPS) Controller
The PIC16F1783T-I/MV's Power Supply Modulation Controller (PSMC) implements current-mode or voltage-mode PWM with programmable dead-band and slope compensation for isolated or non-isolated SMPS. The on-chip op-amp serves as the current-sense amplifier, the 12-bit ADC samples Vin/Vout feedback at the PWM switching edge, and the EUSART interfaces with PMBus™ or UART telemetry. The 28-UQFN 4x4 mm package fits inside an industry-standard 1-inch-square brick converter. The extended -40 to +125 °C variant PIC16F1783T-E/MV is available for harsh-environment power modules.
推薦
Industrial Sensor Signal Conditioning
The PIC16F1783T-I/MV integrates two op-amps, a 12-bit ADC, and an 8-bit DAC for standalone signal conditioning of strain-gauge bridges, thermistors, and pH probes. The PSMC generates excitation PWM for ratiometric sensor reading, while the EUSART broadcasts calibrated output at auto-baud rates. The wide 2.5-5.5 V window operates from a 24 V industrial loop with a series regulator, and the 256 B EEPROM stores per-sensor calibration constants. The 28-UQFN 4x4 mm footprint enables in-line DIN-rail mounters, with the exposed pad dissipating the 0.5 W max dissipation at 25 °C ambient.

主要差異化特點
- Triple 12-bit ADC and 8-bit DAC on a 28-pin UQFN (對比PIC16F1713T-I/MV)
- PSMC peripheral for SMPS and lighting control (對比PIC16F1782T-I/MV)
- Wide 2.5 V to 5.5 V supply with nanoWattMillis XLP™ (對比ATSAM4LS8BA-AUR)
設計說明
Estimated: UQFN-28 4x4 mm packages require a continuous ground pour under the exposed pad. The Microchip PIC16F1783 datasheet lands the EPAD as pin 29 connected to VSS - a thermally connected GND pour (recommend at least 25 mm² of 1 oz copper) keeps the 32 MHz core below 70 °C at 0.5 W dissipation. Solder paste printing should use a 0.5 mm×0.5 mm aperture matrix (typically 4×4 dots) to ensure EPAD voiding stays below 25%.
The PIC16F1783T-I/MV uses Peripheral Pin Select (PPS) for remappable I/O - I2C, SPI, and UART pins must be assigned at runtime in firmware before first peripheral use. Forgetting the PPS unlock sequence (write EECON2=0x55, 0xAA, then PPS configuration) leaves the peripherals silent even with correct SFR initialization. Always verify PPS assignment with a simple PORT-toggle test before integrating with external sensors.
Estimated: At 32 MHz with all peripherals active, the PIC16F1783T-I/MV draws ~3.5 mA at 3.3 V, falling to ~1.8 mA at 1 MHz. For battery-powered designs, configure the MCU in SLEEP mode (instruction SET+CPUOFF pattern via SLP) waking from a timer interrupt at 1 Hz; with this pattern the average current falls under 20 µA, well within the nanoWattMillis XLP™ spec. Use a 0.1 µF ceramic decoupling capacitor within 3 mm of VDD (pin 10) and a 10 µF bulk cap on the input rail.
When routing the 28-UQFN to an external crystal (RA6/RA7), keep trace lengths under 5 mm and surround both with a ground pour island to suppress radiated EMI. For EUSART or SPI buses above 1 MHz, add a 33 Ω series resistor at the driver pin to dampen ringing. The 12-bit ADC accuracy is degraded by digital switching on adjacent RC-port pins; avoid toggling RC7/RC6 within 1 µs of the ADC sample-and-hold acquisition window, or use analog-only ports RA0-RA3 for low-noise ADC channels.
