PIC16LF1779-E/MV - 8-Bit 32MHz MCU 28KB Flash 40-UQFN | Microchip
MPN: PIC16LF1779-E/MV ✓ NakahandaPIC16LF1779-E/MV Ulas
A microcontroller (MCU) is a single-chip computer containing a CPU, non-volatile program memory (Flash), volatile working memory (RAM), and a rich set of on-chip peripherals. PIC® XLP™ (eXtreme Low Power) is Microchip's ultra-low-power branding for nanoWatt technology; the LF sub-family is optimized for applications that demand long battery life and low quiescent draw. Within Microchip's taxonomy, an MCU sits in the broader hierarchy: microcontroller -> embedded processor -> semiconductor device -> electronic component.
Key features of the PIC16LF1779-E/MV include a 10-bit ADC, multiple PWM outputs with complementary waveform generation, programmable ramp generators, op-amps, comparators, and high-resolution configurable logic cells that make it well suited to intelligent analog/digital control. The integrated CIP (Core Independent Peripherals) allow closed-loop functions such as power-conversion control, LED driving, and motor commutation to run without CPU intervention. The device also includes a 32 kHz internal oscillator, on-chip temperature indicator, and a wide operating voltage range suitable for battery-powered systems.
The 40-UQFN (MV) 5x5 mm footprint is one of the densest packages in the PIC16F177x family and offers strong thermal performance through its exposed pad. Device variants are differentiated by suffix codes such as /P (DIP-40), /PT (TQFP-44), /SO (SOIC-28) and /MV (UQFN-40); the /MV option is typically chosen for compact, surface-mount designs where board space is constrained.
Typical applications include LED lighting controllers, switched-mode power supply (SMPS) digital control loops, battery chargers, small brushless-DC motor and fan controllers, sensor signal conditioning, and consumer/industrial IoT nodes. The extended -40°C to +125°C temperature grade makes the -E/MV variant suitable for automotive underhood and harsh industrial environments.
When designing with the PIC16LF1779-E/MV, ensure the exposed pad is soldered to a sufficient copper pour to meet the package's thermal resistance. The LF variant operates down to 1.8 V, but analog peripheral accuracy may degrade below 2.0 V - consult the datasheet electrical characteristics for your specific supply voltage. Programming/debug is supported through ICSP and the MPLAB X IDE ecosystem.

Talaan ng Disenyo
The 40-UQFN (MV) 5x5 mm package uses an exposed thermal pad that must be soldered to a continuous copper pour to meet the datasheet thermal resistance specification. A minimum 1 sq. inch of 1 oz copper on the top layer connected to the exposed pad is recommended. Estimated: at 32 MHz CPU + multiple active analog peripherals, total power dissipation is approximately 15 mW; without the pad properly soldered, junction temperature may rise 10-15°C above ambient at +85°C ambient, reducing device lifetime.
The LF variant operates from 1.8 V to 3.6 V. Decouple VDD with a 100 nF ceramic capacitor placed within 5 mm of the VDD pin, plus a bulk 1-10 µF tantalum or ceramic on the supply rail. For the PIC16LF1779-E/MV's exposed pad (which bonds to VSS internally), ensure low-impedance ground stitching vias around the pad to avoid supply noise coupling into the 10-bit ADC.
Place the ICSP clock (ICSPCLK/RB3) and ICSP data (ICSPDAT/RB2) pins on accessible test pads or header pins for in-circuit programming and debug. The PIC16LF1779-E/MV shares these signals with general-purpose I/O, so the circuit must allow them to be driven externally without contention. Use 4.7 kΩ pull-up resistors on ICSPCLK and ICSPDAT to VDD for production stability.
Do not exceed the 3.6 V maximum VDD - the LF variant is permanently damaged above ~4 V. Use a 3.3 V LDO such as Microchip MCP1700 or MCP1755 with adequate decoupling. When migrating from PIC16F1779 (5 V) to PIC16LF1779 (3.3 V), re-evaluate any external analog signal levels to avoid exceeding the LF ADC's input range. The internal 32 MHz oscillator requires the HFINTOSC to be selected via configuration bits - a common startup issue is leaving the FOSC configuration on the default EC mode.
Keep analog signal traces (ADC inputs, op-amp inputs) short and away from switching signals (PWM outputs, ICSP clock). Route the analog VDD/VSS pairs separately if the layout allows. The PIC16LF1779-E/MV's on-chip op-amps benefit from guard rings around their inputs for high-impedance sensor interfaces. Avoid running digital signals under the exposed pad region to minimize coupling into the analog ground.
