Hardware-level features such as a configurable brown-out reset (BOR) and watchdog timer (WDT) provide robust fault recovery. Typical applications include battery-powered LCD-based consumer products, low-power sensor nodes, household appliances with segment displays, medical monitoring devices, and industrial control panels. Its nanoWatt XLP technology makes it ideal for any application where extended battery life is critical. When designing with this part, evaluate the LCD driver requirements (number of segments, COM/SEG pin count) carefully against the package variant, and place the 0.1 uF Vdd decoupling capacitor within 5 mm of the supply pin. The internal 32 MHz oscillator accuracy (~2%) may require periodic calibration or an external crystal for timing-critical UART communication. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes that go beyond the manufacturer datasheet alone, helping engineers select the right variant for volume production.

PIC16LF1936T-I/MV - 8-Bit XLP MCU, 14KB Flash, 32MHz, 28-UQFN | Microchip

The Microchip Technology PIC16LF1936T-I/MV is an 8-bit PIC microcontroller from the PIC16LF193x family with nanoWatt XLP extreme low-power technology, delivering 32MHz CPU performance with 14KB (8K x 14) of Flash program memory, housed in a 28-pin UQFN (4x4 mm) package with exposed thermal pad. It integrates 256 bytes of EEPROM data memory and 256 bytes of SRAM plus an integrated LCD driver supporting segmented displays for low-power human-machine interface applications. An 8-bit microcontroller is a single-chip computer built around an 8-bit data bus, an ALU, program memory, and a fixed set of peripherals. It belongs to the broader hierarchy of microcontroller -> embedded controller -> semiconductor device, and within the PIC architecture it sits in the enhanced mid-range PIC16F/LF193x family that adds LCD drive, mTouch capacitive sensing, and nanoWatt XLP sleep modes to the classic PIC16 instruction set. Key features include an operating voltage range of 2.3V to 3.6V optimized for battery-powered designs, support for up to 36 I/O pins remappable through the peripheral pin select (PPS) system, a 32MHz internal oscillator, and multiple low-power sleep modes drawing well under 1 microamp. The integrated LCD driver supports up to 96 segments with software-controlled contrast, and the mTouch peripheral enables capacitive touch buttons without external components. The architecture combines a RISC Harvard-style CPU with peripheral pin select, a 10-bit ADC with computation, multiple Enhanced USART, SPI, and I2C interfaces, plus capacitive sensing hardware. The XLP technology delivers sleep currents below 100 nA typical, with RTCC, watchdog timer, and ultra-low-power wake sources that keep standby power well below competing 8-bit cores. Typical applications include battery-powered sensor nodes, consumer remote controls, small household appliances with segmented LCD displays, capacitive touch user interfaces, and metering devices such as thermometers and electricity meters where the LCD driver and XLP are the dominant feature requirements. The wide operating voltage also suits direct 3V coin-cell designs. When designing with the PIC16LF1936T-I/MV, ensure that VDD decoupling uses a 100nF ceramic capacitor placed within 5 mm of the package pin, and that the exposed thermal pad (EP) is soldered to a grounded copper pour for both thermal dissipation and mechanical reliability of the UQFN-28 (MV) body.

PIC16LF1936T-I/SO

PIC16LF1936T-I/SO - 14KB Flash 8-bit MCU | Microchip | SOIC-28

The Microchip Technology PIC16LF1936T-I/SO is an 8-bit flash-based microcontroller with 14KB program memory and an integrated LCD driver, housed in a 28-pin SOIC (SO) wide-body package. It operates up to 32 MHz from a 1.8V to 5.5V supply and delivers nanoWatt XLP ultra-low-power consumption for battery-backed and energy-harvesting designs. On-chip peripherals include 256B EEPROM, 512B RAM, an enhanced mid-range 8-bit CPU core, and up to 36 I/O pins depending on package variant. A PIC microcontroller is a programmable system-on-a-chip combining an 8-bit RISC CPU core, non-volatile flash program memory, SRAM, EEPROM data memory, and a rich set of analog and digital peripherals in a single IC. The PIC16LF1936 belongs to Microchip's enhanced mid-range family, sitting in the hierarchy PIC16LF1936 -> PIC16F1936 family -> PIC16 8-bit MCU family -> PIC microcontroller -> microcontroller -> embedded computing. The 'LF' prefix denotes the low-voltage F-process variant that supports the industry's broadest operating voltage range and the nanoWatt XLP technology. Key features include 14KB flash program memory (8K x 14 words), 512B SRAM, 256B EEPROM, integrated LCD driver supporting up to 96 segments, 11-bit ADC with up to 17 channels, multiple timers, and nanoWatt XLP sleep currents down to 20 nA. The wide 1.8V to 5.5V VDD range allows direct connection to single-cell Li-ion, 3.3V, and 5V rails without level shifters. The PIC16LF1936 is built on Microchip's enhanced mid-range 8-bit core with a 14-bit instruction word, two hardware stack levels for interrupt handling, and a single-cycle instruction architecture at 32 MHz. The integrated LCD driver supports static, 1/2, 1/3, and 1/4 multiplexed LCD glass with on-chip charge pump, eliminating external voltage generation. Compared with the PIC16F1936, the LF variant trades absolute maximum VDD headroom for a much wider operating range and lower quiescent current. Typical applications include battery-powered consumer devices, metering and instrumentation with LCD readout, white goods and appliance control, sensor signal conditioning nodes, and IoT edge nodes with segmented LCD displays. Its low sleep current also makes it well suited to remote controls and energy-harvesting wireless sensor nodes. When designing with this part, route the ICSPCLK/ICSPDAT lines to a dedicated programming header for in-circuit serial programming and place a 100 nF decoupling capacitor within 5 mm of each VDD/VDDCORE pin pair to meet the datasheet's noise budget. Use the on-board MCLR internal pull-up option to free the MCLR pin as an input when no external reset is required.
