PIC16LF1902T-I/ML

PIC16LF1902T-I/ML - 3.5KB Flash 8-Bit MCU w/ LCD | Microchip

The Microchip Technology PIC16LF1902T-I/ML is an 8-bit Flash-based CMOS microcontroller in the PIC16F family with 3.5KB (2K x 14) of program memory, 128 bytes of RAM, and 25 I/O pins, packaged in a 28-pin VQFN (4x4 mm) form factor with an exposed thermal pad. It integrates a 72-segment LCD driver, 11-channel 10-bit ADC with voltage reference, internal 16 MHz oscillator, and Microchip's nanoWatt XLP extreme low-power technology, all in an industrial temperature grade (-40C to +85C) variant supplied on Tape & Reel. A PIC microcontroller (Programmable Integrated Circuit) is a compact 8-bit RISC processor family originally developed by General Instrument's Microelectronics Division and popularized by Microchip. PIC MCUs combine a Harvard-architecture CPU core with on-chip Flash, RAM, and peripherals (ADC, timers, PWM, communication interfaces) into a single IC, positioning them above simple digital logic but below 32-bit microprocessors in the embedded computing hierarchy. PIC16F1xxx-family devices specifically belong to the enhanced mid-range core family with 49 instructions, 16-level hardware stack, and self read/write Flash capability. Key features include a 20 MHz maximum operating frequency (16 MIPS performance at 4 clock cycles per instruction), wide 1.8V to 3.6V operating voltage window for battery-powered designs, integrated temperature indicator, brown-out reset (BOR), extended watchdog timer (EWDT), in-circuit serial programming (ICSP), and an enhanced 8-bit timer (TMR0) plus 16-bit timer (TMR1). The on-chip LCD driver supports up to 72 segments, eliminating the need for an external LCD controller in many HMI applications. Architecturally, the PIC16LF1902T-I/ML uses an 8-bit data path with separate program and data buses, an interrupt controller with hardware context saving, and nanoWatt XLP power management that drops quiescent current into the microamp range during sleep. The peripheral pin select (PPS) feature enables flexible pin assignment for digital functions, while the 10-bit ADC with internal voltage reference supports ratiometric measurements on battery or sensor channels. Typical applications include battery-powered LCD-based consumer products (thermostats, remote controls, weighing scales, kitchen timers), portable medical devices requiring low-power LCD HMI, industrial sensor transmitters with LCD readout, smart home keypads, and any cost-sensitive embedded design needing integrated LCD without an external driver IC. The wide 1.8V-3.6V range supports direct connection to two AA alkaline cells or single-cell Li-Ion chemistries. When designing with this device, note that the VQFN-28 (ML) package requires a ground plane via the exposed thermal pad for both thermal dissipation and electrical grounding; neglecting this pad is a common cause of MCU malfunction. Also confirm oscillator selection and PPS locking during bring-up, since the internal 16 MHz HFINTOSC and PLL configurations differ from older PIC16F parts.

PIC16LF1906T-I/SO - 8-bit MCU, 14KB Flash, LCD, XLP | Microchip
PIC16LF1906T-I/SO

PIC16LF1906T-I/SO - 8-bit MCU, 14KB Flash, LCD, XLP | Microchip

The Microchip PIC16LF1906T-I/SO is an 8-bit Flash-based CMOS microcontroller from the PIC16F family, featuring 14KB of program memory, 512 bytes of RAM, and an integrated LCD driver, housed in a 28-pin SOIC (SO) wide-body package. The device operates from 1.8V to 3.6V, runs at up to 20 MHz internal oscillator, and is built on Microchip's nanoWatt XLP extreme-low-power technology for battery-friendly designs. A PIC16F-series microcontroller is an 8-bit RISC-based MCU using a modified Harvard architecture with separate program and data buses, which lets the CPU fetch the next instruction while accessing data memory in the same cycle. Within the broader taxonomy, PIC16LF1906 belongs to the PIC16F family, which itself sits under the PIC microcontroller hierarchy, then to 8-bit microcontrollers, MCUs, microprocessors, and finally to embedded semiconductors. The 'LF' prefix denotes the low-voltage (1.8V-3.6V) process variant, while 'XLP' (eXtreme Low Power) is Microchip's branded nanoWatt technology that delivers sub-microamp sleep currents. Key features include 14KB (8K x 14 words) of self-programmable Flash, 512 bytes of data SRAM, 256 bytes of EEPROM, an integrated segmented LCD driver with charge pump, a 10-bit ADC with up to 17 channels, and multiple serial interfaces (I2C/SPI, EUSART). The 'T' suffix designates a Tape & Reel packaging option for high-volume SMT assembly, while 'I' indicates the industrial -40C to +85C operating temperature range, and 'SO' specifies the 28-pin 7.50 mm wide SOIC package. The architecture combines a 16-level hardware stack, 49 instructions, and a 31 kHz to 20 MHz internal oscillator that supports PLL operation. Peripherals include multiple 8-bit and 16-bit timers, comparators, a master synchronous serial port (MSSP) configurable as SPI or I2C, and an enhanced universal synchronous/asynchronous receiver/transmitter (EUSART). The integrated LCD driver supports up to 116 segments with variable contrast and a charge pump for low-voltage operation. Typical applications include battery-powered consumer products such as thermostats and remote controls, industrial metering and sensor front-ends with on-glass LCD readouts, IoT edge nodes that sleep for years on a single cell, white-goods user interfaces, and portable medical monitoring devices. The wide -40C to +85C industrial temperature range and XLP nanoWatt sleep modes below 1 uA make it particularly attractive for always-on, energy-harvesting, or coin-cell powered designs. When designing with this part, allocate PCB area for the ICSP/ICD programming/debug header because every PIC16LF1906 ships blank and requires Microchip's MPLAB X IDE plus a programmer (PICkit, ICD, or Snap) to load firmware. Plan decoupling: a 100 nF ceramic on VDD close to the pin, plus a bulk 1-10 uF on AVDD, is a safe baseline. Total Flash endurance is rated at 100K erase/write cycles, so reserve EEPROM for frequently-changed parameters. This page synthesizes distributor pricing (Heisener, LCSC, DigiKey), drop-in package alternatives (28-SOIC), and practical design notes not found in the standalone manufacturer datasheet to help engineers evaluate the PIC16LF1906T-I/SO in days rather than weeks.

PIC16LF1906T-I/SS - 14KB Flash LCD 8-bit MCU | Microchip

The Microchip PIC16LF1906T-I/SS is a 28-pin SSOP-packaged 8-bit PIC microcontroller from the PIC® XLP™ 16F family, featuring 14KB of Flash program memory, 512 bytes of RAM, and an integrated LCD driver. It operates up to 20MHz from a 1.8V to 3.6V supply, making it part of the nanoWatt XLP (eXtreme Low Power) family engineered for battery-powered and energy-harvesting designs. A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory (Flash), data memory (RAM), and a rich set of peripherals (ADC, timers, communication ports, LCD driver) into one package. The PIC16LF1906 belongs to the 8-bit PIC mid-range family — within the broader hierarchy of microcontrollers (8-bit MCU → PIC microcontroller → PIC16 family → PIC16F190x sub-family → semiconductor). The "LF" prefix denotes the low-voltage, low-power variant, while the trailing "T" denotes tape-and-reel packaging for high-volume assembly. Key features include 14KB (8K × 14 words) of self-programmable Flash, 512 bytes of RAM, 256 bytes of EEPROM, a 10-bit ADC with up to 11 channels, an integrated LCD driver supporting up to 116 segments, multiple communication peripherals (I2C/SPI/EUSART), and nanoWatt XLP technology with sleep currents down to approximately 50 nA. The device includes an on-chip 32kHz oscillator, multiple timer modules, and an enhanced mid-range 14-bit instruction set. The PIC16LF1906 employs a RISC architecture with a 14-bit instruction word and an 8-bit data path, providing predictable timing suitable for real-time control. The integrated LCD driver eliminates the need for an external LCD controller, reducing BOM cost and PCB area. The nanoWatt XLP technology offers multiple low-power modes (Run, Idle, Sleep, and Deep Sleep), making it well suited to applications where average current draw must remain in the microamp range. Typical applications include battery-powered consumer products with LCD displays such as thermostats, portable medical monitors, utility metering, electronic shelf labels, and IoT sensor nodes with embedded segment LCDs. Designers value the part's ability to drive a glass LCD directly while consuming minimal quiescent current, enabling years of operation from a single coin cell. When designing with the PIC16LF1906T-I/SS, ensure the chosen LCD segment multiplex configuration matches the panel's COM/SEG count. Use the MPLAB Code Configurator (MCC) plug-in to set up the LCD charge pump and waveform timing, and budget adequate decoupling on VDD/AVDD to support the LCD charge-pump switching transients.

PIC16LF1907-E/MV

PIC16LF1907-E/MV - 14KB Flash 8-bit MCU with LCD | Microchip

The Microchip PIC16LF1907-E/MV is a 14KB Flash, 512B RAM, 8-bit PIC microcontroller in a 40-pin UQFN (5x5 mm) package, featuring nanoWatt XLP extreme low-power technology and an integrated LCD driver. The 'LF' prefix indicates the wide-Vdd 1.8V-3.6V operating range optimized for battery-powered designs, and the -E suffix designates the -40C to +125C industrial temperature grade. The 'MV' suffix denotes the 40-terminal UQFN (HVQCCN, 5x5x0.5 mm) surface-mount package. An 8-bit microcontroller (MCU) is a single-chip processor that integrates a CPU, Flash program memory, RAM, and peripherals on one die, executing instructions one byte at a time. PIC microcontrollers use a modified Harvard RISC architecture with separate program and data buses, which historically delivered higher code density and deterministic interrupt latency than CISC alternatives. Within the broader taxonomy, the PIC16LF1907 belongs to the PIC16 family -> 8-bit PIC MCUs -> microcontrollers -> embedded processors -> semiconductors. Key features include a 20 MHz internal oscillator, 14 KB of self-programmable Flash (8K x 14 words), 512 bytes of RAM, 256 bytes of EEPROM, an integrated LCD controller with up to 116 segments, a 10-bit ADC with up to 14 channels, multiple Enhanced Universal Synchronous/Asynchronous Receiver/Transmitter (EUSART) and I2C/SPI peripherals, and Microchip's nanoWatt XLP sleep currents as low as 20 nA. The 40-UQFN package provides a compact, lead-free footprint suited to space-constrained consumer and industrial designs. The device uses Microchip's enhanced mid-range 8-bit core with a 14-bit instruction word, allowing each Flash location to hold one 14-bit PIC instruction. This produces measurable code-density advantages over 8-bit instruction MCUs from 8051-class competitors. The integrated LCD driver supports both static and multiplexed bias modes, eliminating external segment drivers for small-display modules such as appliance front panels and metering readouts. Typical applications include battery-powered sensor nodes, household appliance user interfaces with LCD readout, industrial metering, IoT edge nodes, wearable health monitors, and remote controls. The nanoWatt XLP feature set allows multi-year operation from a single coin cell when the MCU spends most of its time in Sleep. When designing the PCB, route the 40-UQFN's exposed thermal pad (EP) to a continuous ground copper pour to provide both thermal dissipation and a low-impedance ground reference. Microchip's MPLAB X IDE with XC8 compiler, the PICkit 4 / MPLAB Snap programmers, and the MPLAB Code Configurator peripheral library accelerate firmware bring-up for this family.
