PIC16LF1783T-I/ML - 8-bit 32MHz 7KB Flash MCU 28-QFN | Microchip
MPN: PIC16LF1783T-I/ML ✓ Hoạt độngPIC16LF1783T-I/ML Tóm tắt
A PIC microcontroller is a low-power, deterministic Harvard-architecture MCU widely used for embedded control. Within the broader taxonomy, it falls under microcontroller (MCU) -> microprocessor -> semiconductor -> integrated circuit. The 'LF' prefix designates the extended XLP (eXtreme Low Power) family, optimized for battery-operated applications where active current and sleep current are critical. The PIC16F1783 sits in the mid-range PIC16F1xx family with enhanced peripherals aimed at sensor signal conditioning, LED driving, and motor control tasks.
Key features of the PIC16LF1783 include 8-bit core at 32 MHz (8 MIPS), 7KB Flash, 512B RAM, 256B EEPROM, 12-bit ADC with up to 14 channels, 8-bit DAC, two op-amps, comparators, PWM modules, CWG, CLC, NCO, and EUSART/I2C/SPI. The 'LF' variant supports 1.8V-3.6V operation, while the 'F' (non-LF) variant supports up to 5.5V. The QFN-28 (ML) package offers a small 6x6 mm footprint with an exposed thermal pad for improved thermal performance.
The device uses Microchip's enhanced mid-range 8-bit CPU core with a hardware multiplier and 16-level hardware stack, providing predictable interrupt latency essential for real-time control loops. Internal oscillator calibration to ±1% enables reliable UART communication without external crystals in many designs.
Typical applications include battery-powered sensor nodes, IoT edge devices, LED lighting controllers, motor/valve drivers, e-metering, and consumer white goods. Its integrated op-amps and 12-bit ADC enable direct bridge-sensor interfacing without external signal conditioning. The XLP nanoWatt sleep mode (down to sub-uA) makes it ideal for energy-harvesting applications.
When designing with the PIC16LF1783, ensure that VDD does not exceed 3.6V (LF variant), as this will damage the part; consider PIC16F1783 for 5V designs. Use the exposed pad (EP) for both thermal dissipation and PCB ground return by soldering it to the inner ground plane.

Battery-Powered IoT Sensor Nodes
The PIC16LF1783's XLP nanoWatt technology provides sub-microamp sleep current, and the 1.8V-3.6V operating range makes it ideal for direct connection to single-cell Li-ion or 2x alkaline cells. Its integrated 12-bit ADC (up to 14 channels) and two on-chip op-amps enable direct bridge-sensor interfacing (load cells, strain gauges) without external instrumentation amplifiers. At a 32 MHz CPU clock the device draws only a few mA active, and waking from sleep on ADC interrupt allows duty-cycled measurements for 5-10 year battery life on a typical CR2032 cell.

Ghi chú thiết kế
The PIC16LF1783T-I/ML is a LF (low-voltage) variant with VDD max 3.6V; applying 5V will permanently damage the part. For 5V-tolerant designs, use the PIC16F1783T-I/ML (without L) which supports 2.3V to 5.5V operation and shares the same QFN-28 footprint. Always include a 100nF decoupling capacitor within 5 mm of each VDD pin pair (pins 10/28) plus a bulk 10uF tantalum or ceramic on the main VDD rail. The exposed pad (EP) must be soldered to a continuous ground plane for thermal dissipation and low-impedance ground return.
Route the ICSP signals (PGC = pin 17 / RB6, PGD = pin 18 / RB7) with short traces to a programming header. Microchip recommends a 4.7k-10k pull-up on MCLR/VPP for reliable in-circuit programming. For the QFN-28 (6x6) layout, use 0.5 mm pitch traces with via-in-pad or near-pad stitching vias to the ground plane under the EP. Avoid routing analog ADC traces (AN0-AN13) near PWM or switching signals; keep analog ground separate from digital ground and join at a single point near the MCU's VSS pin.
Do not assume GPIO pins default to analog on reset - on the PIC16LF1783 most pins default to analog input mode, which can cause unexpected current draw if a digital output is later toggled without reconfiguring the ANSEL register. After every POR/BOR, configure ANSEL, TRIS, LAT, and WPU before enabling peripherals. The on-chip DAC and op-amp outputs require explicit peripheral enable bits; they are OFF by default. Estimated: at 32 MHz active current is approximately 4 mA typical; ensure your LDO can supply at least 30 mA peak for MCU + peripherals.
Thông tin tuân thủ
RoHS and REACH compliant per Microchip product page. Standard -I temperature grade; -E variant is also industrial but extended. Not AEC-Q100 qualified - for automotive, consider PIC16F1783 with proper automotive part number suffix.
