PIC16F1719-I/MV Tóm tắt

The Microchip Technology PIC16F1719-I/MV is a cost-effective 8-bit PIC microcontroller with 28KB Flash, 2KB RAM, and 32 MHz operation, housed in a 40-pin UQFN (5x5 mm) package with exposed pad. It belongs to the PIC16F1717/8/9 family and integrates Intelligent Analog peripherals (Op Amps, 10-bit ADC with computation, 5/8-bit DAC), Core Independent Peripherals (CLC, COG, NCO, ZCD) and Peripheral Pin Select for flexible pin mapping.

A microcontroller (MCU) is a single-chip computer containing a CPU, Flash program memory, SRAM, and a rich set of peripherals (ADC, timers, communication interfaces). PIC microcontrollers are based on a modified Harvard RISC architecture optimized for deterministic, low-power embedded control. The PIC16F1719 sits within Microchip's mid-range MCU portfolio: PIC (family) -> PIC16 (sub-family) -> PIC16F1719 (device) -> 8-bit microcontroller -> embedded MCU -> semiconductor IC.

Key features include up to 32 MHz CPU speed, 28KB self-programmable Flash with 16K x 14 word organization, 2KB RAM, 256B EEPROM, two operational amplifiers, one 10-bit ADC, two 5-bit and one 8-bit DAC, Enhanced PWM, multiple communication peripherals (EUSART, I2C, SPI), and Microchip's eXtreme Low Power (XLP) technology. Voltage operation is 2.3V to 5.5V for the LF variant; the F variant operates up to 5.5V.

The device uses a 14-bit instruction word and 8-bit data path with a hardware multiplier, enabling efficient C and assembly code generation. The on-chip op amps and 10-bit ADC with automated Capacitive Voltage Divider (CVD) make it well suited for sensor interfaces, while CLC and NCO support generation of custom waveforms and high-resolution timing without CPU intervention.

Typical applications include sensor signal conditioning, LED lighting control, low-power IoT nodes, household appliances, and general-purpose embedded control. The PIC16F1719 also fits battery-powered designs thanks to XLP sleep currents in the microamp range.

When designing with this MCU, reserve the exposed pad (EP) as a thermal/ground bond - the UQFN EP must be soldered to a sufficient copper pour for electrical and thermal performance. Choose the LF (PIC16LF1719) variant if you must operate below 2.3V.

Both share the same Intelligent Analog peripherals (Op Amps, 10-bit ADC, DACs) and Core Independent Peripherals (CLC, COG, NCO, ZCD). Choose PIC16F1719-I/MV for applications needing more code space and RAM; choose PIC16F1718 for cost-sensitive designs that fit in 16KB.

PIC16F1719 vs PIC16F1709 - what is the difference?

The PIC16F1719 is the higher-memory sibling of the PIC16F1709 (28KB vs 7KB Flash, 2KB vs 512B RAM). Both share the same peripheral set including 10-bit ADC, op amps, CLC, NCO, and PPS. The PIC16F1719-I/MV is the better choice for C-based applications, while the PIC16F1709 is preferred for cost-optimized assembly or small C projects.

When should I choose PIC16F1719-I/MV over PIC16LF1719?

Choose the PIC16F1719-I/MV (F variant) when your design operates from 2.3V to 5.5V; choose the PIC16LF1719 when you need operation down to 1.8V for two-cell battery or coin-cell designs. The LF variant has the same peripherals and pinout, with slightly lower maximum CPU speed at low voltage. For most 3.3V and 5V embedded designs the F variant is sufficient.

Is PIC16F1719-I/MV suitable for low-power IoT sensor nodes?

Yes, the PIC16F1719-I/MV is well suited for low-power IoT sensor nodes thanks to Microchip's XLP (eXtreme Low Power) technology, with sleep currents in the nanoamp range and multiple low-power modes (sleep, dozing, peripheral module disable).

Ghi chú thiết kế

The 40-pin UQFN package has a large central exposed pad that must be soldered to a sufficient PCB ground copper pour (recommended minimum 1 sq inch continuous ground plane). Leaving the EP unsoldered can cause thermal stress, electrical discontinuities, and EMI degradation. Add multiple thermal vias under the EP to improve heat dissipation and reduce ground impedance for the analog blocks.

Place 100 nF decoupling capacitors as close as possible to every VDD/AVDD pin and a single bulk capacitor (e.g., 10 uF) near the MCU. The PIC16F1719 has separate analog (AVDD/AVSS) and digital (VDD/VSS) supply pins to reduce digital switching noise coupling into the ADC; tie AVDD to VDD via a small ferrite bead or filter if high-precision ADC readings are required. Use PPS to remap peripherals to pins away from high-frequency switching traces.

The PIC16F1719-F (non-LF) variant is rated 2.3V to 5.5V; operating below 2.3V will cause Flash read errors and ADC inaccuracy. If the design runs from a 1.8V rail, use the PIC16LF1719 instead. Also note that the MCLR pin (RE3) is input-only on this family and has an internal pull-up enabled by configuration bits; leave it disconnected if not used for in-circuit programming.
