PIC16LF721T-I/SO - 7KB Flash 8-bit MCU | Microchip 20-SOIC

The Microchip Technology PIC16LF721T-I/SO is an 8-bit PIC RISC microcontroller with 7 KB of Flash program memory, 256 bytes of SRAM, and 128 bytes of EEPROM data memory, housed in a 20-pin SOIC (SO) package with Tape & Reel packaging. The part operates from a 1.8 V to 3.6 V supply (F-variant LF) and runs the PIC16 core at up to 16 MHz instruction execution, while the internal oscillator block supports up to 32 MHz. According to the Microchip PIC16F720/721 datasheet (DS41631B-family), the device provides 18 digital I/O pins with individual direction control and nanoWatt XLP extreme-low-power technology for sleep currents in the sub-microamp range. A microcontroller (MCU) is an integrated circuit containing a CPU core, program memory (Flash/ROM), data memory (RAM), and peripherals such as timers, ADC, communication interfaces, and I/O pins on a single chip. PIC16 microcontrollers sit in the 8-bit RISC segment of the broader microcontroller taxonomy, which itself belongs to the larger power management and embedded control semiconductor family. They are commonly chosen for low-power, deterministic, cost-sensitive embedded designs. Key features of the PIC16LF721 include 7 KB self-programmable Flash (4K x 14 words), 256 bytes of SRAM, 128 bytes of data EEPROM, 18 I/O pins, an enhanced 8-bit timer (Timer1/2/3) set, a 10-bit ADC with up to 14 channels, capture/compare/PWM modules, an I2C/SPI/USART (AUSART) interface, and nanoWatt XLP technology that drops the typical sleep current below 1 uA. The LF designator means the part is built for 1.8 V minimum operation, allowing direct battery connection in 2x AA / coin-cell designs. The PIC16LF721T-I/SO uses a Harvard-architecture PIC16 RISC core with a 14-bit instruction word, single-cycle ALU operations, and a hardware multiplier. The LF process node and XLP design deliver active currents around 1 mA/MIPS at 3.3 V and standby currents of roughly 50-100 nA with the watchdog timer disabled, making the device well suited to always-on sensor nodes that spend most of their life in sleep. Typical applications include battery-powered IoT sensor nodes, low-energy remote controls, wearable health patches, 2.4 GHz RF transmitter companion controllers, low-end motor control, and small consumer appliances. The industrial (-I) temperature grade of -40C to +85C supports outdoor and factory-floor deployment. When designing, place a 100 nF decoupling capacitor on VDD as close to the pin as possible and bulk-decouple the MCLR line. Configure unused I/O as outputs driven low to minimize current draw in sleep, and use the LF variant only when sub-3.6 V battery operation is required; otherwise, the standard PIC16F721 (up to 5.5 V) provides more supply margin. This page synthesizes distributor pricing, drop-in alternatives in the same 20-pin SOIC footprint, and practical low-power design notes beyond the datasheet to help engineers select and source the PIC16LF721T-I/SO quickly.

PIC16LF722-E/SO

PIC16LF722-E/SO - 8-bit XLP MCU, 3.5KB Flash, 28-SOIC | Microchip

The Microchip Technology PIC16LF722-E/SO is an 8-bit flash microcontroller from the PIC16F family with nanoWatt XLP (eXtreme Low Power) technology, delivering 3.5KB (2K x 14 words) of program Flash memory and 128 bytes of RAM in a 28-pin SOIC (SO) wide-body package. It operates from 1.8V to 3.6V (LF variant), supports a 20 MHz instruction cycle, and integrates a 10-bit ADC, capture/compare/PWM (CCP/ECCP) peripherals, and a USART. The -E suffix denotes the extended operating temperature grade of -40C to +125C. An 8-bit microcontroller (MCU) is a programmable single-chip computer that integrates a CPU, RAM, non-volatile program memory (Flash), and peripherals onto one silicon die. Within the broader taxonomy, this PIC16LF722 belongs to the Microchip PIC16 mid-range family -> PIC16F family -> 8-bit MCU -> microcontroller -> semiconductor. The 'LF' prefix denotes the low-voltage (1.8V-3.6V) variant while the 'F' family uses the standard mid-range 14-bit instruction set. MCUs are fundamental building blocks of embedded systems, executing firmware that reads sensors, drives actuators, and exchanges data with other ICs. Key features of the PIC16LF722-E/SO include nanoWatt XLP technology for ultra-low sleep currents (typical 20 nA in sleep with WDT disabled), one 8-bit and one 16-bit timer, a 10-bit ADC with up to 11 input channels, an enhanced USART, an ECCP module for motor/lighting control, and an internal oscillator with software-tunable frequency. The integrated ADC eliminates external signal-conditioning components, while the ECCP module reduces BOM cost for brushed DC motor or power-MOSFET drive applications. The LF process node enables typical run current below 200 uA/MHz and sleep current down to 20 nA, making the part well suited to battery-powered IoT, sensor, and remote-control products. The device's instruction cycle equals one quarter of the oscillator frequency, so a 20 MHz crystal yields a 5 MIPS instruction throughput. Programming is supported through Microchip's ICSP (In-Circuit Serial Programming) interface and the MPLAB X IDE toolchain. Typical applications include consumer electronics remote controls, low-power sensor nodes, battery chargers, small appliance controls, and hobby/educational embedded platforms. The 28-pin SOIC footprint is friendly to hand-soldering and breadboard adapters, simplifying prototyping. A critical design consideration is decoupling: place a 100 nF ceramic capacitor between VDD and VSS within 5 mm of the IC, plus a bulk 1 uF to 10 uF capacitor on the power rail. The MCLR reset pin should be pulled high through a 10 kohm resistor for normal operation, or tied directly to VDD if unused.

The Microchip PIC16LF722A-E/MV is an 8-bit PIC XLP 16F microcontroller delivering 20 MIPS of CPU throughput at 3.5KB Flash program memory and 192 bytes of RAM, housed in a 28-pin UQFN-EP (4x4 mm) exposed-pad surface-mount package. It operates across a 1.8V to 3.6V supply voltage range (datasheet lists 2.3V-3.6V for Vdd min/max), supports internal oscillator up to 16 MHz (with 32 MHz PLL option), and integrates nanoWatt XLP technology for ultra-low-power sleep currents down to 20 nA typical. A microcontroller (MCU) is an integrated circuit that combines a CPU core, program memory (Flash/ROM), data memory (RAM), and configurable peripherals (ADC, timers, communication interfaces) into a single chip. The PIC16LF722A belongs to the mid-range 8-bit PIC16 family within Microchip's PIC microcontroller hierarchy, optimized for low-power and battery-friendly embedded designs. Unlike more complex 32-bit Cortex-M MCUs, 8-bit PICs use a RISC-style instruction set with a 14-bit wide Flash word, giving simple deterministic timing and easy code migration. Key features include 11-channel 8-bit ADC, two 8-bit timers plus one 16-bit timer, enhanced PWM module with up to 4 output channels, I2C/SPI/EUSART communication interfaces, internal voltage regulator (F variants only, not the LF), and a wide operating temperature range of -40C to +125C. The nanoWatt XLP feature supports multiple low-power modes (doze, idle, sleep) with peripheral-disabled current draw below 1 uA in sleep. The 28-UQFN (4x4 mm) exposed-pad package offers compact PCB footprint and excellent thermal dissipation via the central thermal pad, which must be soldered to a copper pour. The 'E' suffix designates the -40C to +125C extended industrial temperature grade. The 'MV' suffix specifies the UQFN-28 (4x4) package.

PIC16LF722A-E/SO

PIC16LF722A-E/SO - 8-bit 20MHz 3.5KB Flash MCU | Microchip

The Microchip Technology PIC16LF722A-E/SO is an 8-bit RISC microcontroller from the PIC PIC® XLP™ 16F family, featuring 3.5KB (2K x 14 words) of Flash program memory and operating up to 20 MHz core clock. Housed in a 28-pin SOIC (SO) wide-body package, the device operates across a 1.8V to 3.6V supply range and integrates nanoWatt XLP™ extreme-low-power technology for battery-friendly designs. An 8-bit microcontroller (MCU) is a single-chip computer built around an 8-bit data path, a small program store, and on-chip peripherals. In the component taxonomy the PIC16LF722A sits within 8-bit microcontrollers -> microcontrollers (MCU) -> microcontrollers and microprocessors -> integrated circuits -> semiconductors. It targets embedded control where cost, deterministic behavior, and ultra-low sleep current matter more than raw compute throughput. Key specifications include 128 bytes of SRAM, 256 bytes of EEPROM, an internal 16 MHz oscillator, an integrated ADC, multiple timers, PWM modules, and standard serial peripherals (I²C/SPI, USART with LIN support). The "LF" prefix denotes the wide-voltage, low-power variant, while the "A" suffix indicates the enhanced revision with improved peripherals and nanoWatt XLP™ sleep modes. Together they target battery-powered industrial, white-good, and human-interface control designs. Architecture-wise the PIC16LF722A uses a 14-bit instruction word RISC core, hardware stack, and a Harvard bus structure separating program Flash from data SRAM. The wide 1.8V–3.6V supply removes the need for a separate voltage regulator in 2-cell battery packs; nanoWatt XLP™ further reduces sleep current to microamp levels, enabling years of operation from a CR2032 or two AA cells. On-chip peripherals are multiplexed across the 28-pin SOIC footprint, giving designers I/O flexibility without external logic. Typical applications include consumer and home appliances, low-cost industrial control nodes, USB-less human-interface devices, sensor hubs, LED lighting controllers, and 3.3V-operated remote-control transmitters. It is also used in white goods, small appliances, and battery-driven instruments that benefit from XLP™ sleep-mode behavior. Design consideration: when migrating from the legacy PIC16F722A, note the wider supply range (1.8V–3.6V vs the older 2.0V–5.5V window), that BOR/LVP/ICSP behavior match the PIC16F family, and that microcontrollers require external decoupling and ICSP programming header — the device must be reset at startup and the MCLR pin handled correctly for reliable field use. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet alone, providing engineers a fast path to drop-in compatible 28-SOIC PIC16 alternatives and selection guidance for 3.3V XLP™ designs.

It operates from 2.0V to 3.6V (LF variant, low-voltage), executes one instruction per clock cycle (RISC) and integrates nanoWatt XLP extreme-low-power technology for battery-friendly designs. An 8-bit microcontroller (MCU) is a single-chip computer built around an 8-bit data path, typically used for embedded control tasks such as sensor reading, simple motor actuation, user-interface handling, and protocol bridging. Within the semiconductor taxonomy, this places it as an MCU -> microcontroller -> embedded processor -> semiconductor. The PIC16 mid-range core family, designed by Microchip, offers 35 instructions, 8 hardware stack levels, and direct/indirect/relative addressing, making it a widely deployed choice for cost-sensitive, low-power applications. Key features include 36 I/O pins, multiple communication peripherals (UART, SPI, I2C), 11 ADC channels with 8-bit resolution, and a wide operating temperature range of -40C to +125C (the -E suffix denotes the extended industrial temperature grade). The 28-SPDIP package is pinout-compatible with other 28-pin PIC16CXXX and PIC16FXXX devices, simplifying migration and reuse of legacy designs. Architecturally, the PIC16LF722A uses a Harvard bus architecture with separate program and data memories, single-cycle instruction execution at the system clock rate, and integrated peripherals clock-gated by power-management registers. Compared to the PIC16F722A, the LF (low-voltage) variant omits the internal LDO voltage regulator, eliminating the need for an external VCAP capacitor and supporting direct low-voltage operation down to 2.0V. Typical applications include low-power IoT sensor nodes, battery-powered consumer devices, white-goods and appliance control boards, industrial remote-control modules, and portable medical peripherals. The combination of nanoWatt XLP sleep currents and a generous peripheral set makes it well suited to any application that must sleep for long intervals between active events. When designing with this part, ensure that the supply voltage stays within the 2.0V-3.6V window. For migration to the PIC16F722A, remember to add an external VCAP capacitor on the designated VCAP pin because the F variant includes the internal LDO regulator that the LF variant does not. Confirm pinout compatibility against the family compatibility chart when migrating from older PIC16 devices.

The PIC16 (Peripheral Interface Controller, 16-bit instruction word) is Microchip's mid-range 8-bit MCU family — a Harvard-architecture RISC processor with a single accumulator (WREG), 35 instructions, 8-level hardware stack, and a wide peripheral set. It sits in the hierarchy: PIC microcontroller -> 8-bit MCU -> microcontroller -> embedded computing IC. PIC16F variants use Flash program memory and have become the de-facto reference for low-power, low-cost embedded control in commercial and industrial products.

PIC16LF722T-I/SO

PIC16LF722T-I/SO - 8-bit MCU, 3.5KB Flash, 20MHz, 28-SOIC | Microchip

The Microchip Technology PIC16LF722T-I/SO is an 8-bit PIC16F-series flash microcontroller with 3.5 KB of program memory (2K x 14 words), 128 bytes of RAM, and an integrated 16 MHz internal oscillator, all housed in a 28-pin SOIC wide-body (SO) package supplied on tape and reel. It supports a 20 MHz instruction execution rate (200 ns instruction cycle), a 2.3 V to 3.6 V supply range, and up to 36 I/O ports depending on the package, while operating across the industrial -40 C to +85 C temperature range. An 8-bit microcontroller (MCU) is a compact, self-contained processor core with on-chip flash, RAM, and peripherals designed for embedded control. The PIC16F architecture (Microchip's mid-range 8-bit core) is one of the longest-running MCU families and is widely used in cost-sensitive, low-power, and deterministic real-time applications. Microcontrollers occupy the broader taxonomy: microcontroller -> embedded processor -> semiconductor -> integrated circuit. PIC16F devices specifically implement the PIC16 mid-range instruction set (35 single-word instructions), providing deterministic execution suitable for motor control, sensor reading, and human-machine interface functions. The PIC16LF722T-I/SO includes an internal 16 MHz oscillator accurate to within ±1% (factory calibrated) that eliminates an external crystal in many designs. Its nanoWatt XLP technology provides extreme low-power sleep modes with currents well under 1 microamp, making it ideal for battery-powered applications. The on-chip peripherals typically include multiple timers, a 10-bit ADC, comparators, PWM modules, and an asynchronous serial port (EUSART) - these are described in detail in the PIC16(L)F722/3/4/6/7 datasheet family document. The wide 1.8 V-5.5 V operating range (where the 'LF' prefix denotes the low-voltage variant) gives designers flexibility to power the MCU directly from a single Li-ion cell or a regulated 3.3 V rail. Typical applications include small consumer appliances, low-cost remote controls, sensor nodes, LED drivers, battery chargers, fan controllers, thermostat front-ends, and industrial instrumentation where deterministic 8-bit control is acceptable. For designs requiring the same footprint but lower power, the PIC16LF720 family is a drop-in alternative with reduced flash and fewer peripherals. A common design pitfall is confusing the 'LF' (low-voltage, 1.8 V-5.5 V) prefix with the 'F' (full-voltage, up to 5.5 V) prefix - the standard PIC16F722T-I/SO has the same pinout but lacks the LF voltage headroom. Always confirm the supply voltage rating before substituting. The 'T' suffix in the part number indicates Tape & Reel packaging per Microchip convention.

PIC16LF722T-I/SS

PIC16LF722T-I/SS - 8-Bit MCU, 3.5KB Flash, 20MHz, 28-SSOP | Microchip

The Microchip Technology PIC16LF722T-I/SS is an 8-bit PIC microcontroller built on the enhanced mid-range nanoWatt XLP core, delivering 3.5KB of Flash program memory, 128 bytes of RAM and 256 bytes of EEPROM in a 28-pin SSOP (5.30 mm body width, "SS") package. According to distributor listings from Mouser and Octopart, the device operates from a wide 1.8V to 3.6V supply and runs at up to 20 MHz instruction clock, supporting low-power sleep currents in the nanoWatt eXtended Low-Power family. An 8-bit microcontroller (MCU) is a single-chip processor with an 8-bit data path, integrated program memory, RAM, and peripherals, intended for embedded control tasks such as sensor reading, user I/O handling, and protocol bridging. The PIC16LF722 belongs to the broader PIC16 family (16-bit instruction word, 8-bit data bus) which sits inside Microchip's "MCU" category above simple digital logic and below 16/32-bit microcontrollers and DSPs. The "LF" prefix denotes the low-voltage variant optimized for battery-powered systems; the "T" suffix marks the tape-and-reel packaging option; "I" indicates the industrial -40C to +85C temperature grade; and "/SS" specifies the 28-pin SSOP SMT footprint. Key features include an internal 16 MHz high-speed oscillator (with PLL options reach the LF series 20 MHz fOSC max), a configurable 8/16-bit Timer0, a 16-bit Timer1, an enhanced USART, MSSP for SPI/I2C, a 10-/12-bit ADC with computation, up to 25 mA source/sink on I/O pins, and nanoWatt XLP technology that delivers sleep currents below 1 uA for battery-backed sensor and remote-control applications. Code protection, a configurable Watchdog Timer, In-Circuit Serial Programming (ICSP) and In-Circuit Debug (ICD) round out the typical PIC mid-range feature set. Typical applications include battery-powered sensor nodes, low-energy remote keyless entry, consumer appliances, white-goods user interfaces, low-cost motor control signal conditioning, and general-purpose 8-bit glue logic replacement. The device is also widely used in educational and hobby platforms due to its simple toolchain and abundant example code. When designing with this MCU, ensure the MCLR reset circuitry uses a 10-50 kohm pull-up to VDD and that decoupling capacitors (100 nF plus 1-10 uF bulk) sit within 5 mm of VDD/VSS. The LF 1.8V-3.6V range lets designers standardize on a single-cell Li-ion or two-AA supply, but the 20 MHz fOSC ceiling means timing-critical loops must respect the 200 ns instruction cycle budget at full speed.

It supports clock speeds up to 20 MHz from the verified distributor data, delivers a supply-voltage range of 1.8V to 5.5V, and integrates Microchip's nanoWatt eXtreme Low Power (XLP) technology. The device is part of the PIC16F/LF723 family and includes a hardware LCD driver, A/D converter, multiple timers, and EUSART/SPI/I2C peripherals. A microcontroller (MCU) is a single-chip computer that integrates a CPU, non-volatile program memory, working RAM, and a set of peripheral interfaces in one package. Within the broader semiconductor taxonomy, a microcontroller sits under the 8-bit MCU family, which traces up to embedded processors -> microcontrollers -> integrated circuits. The "LF" prefix denotes Microchip's low-voltage F-variant family optimized for ultra-low power operation, while "XLP" indicates nanoWatt eXtreme Low Power technology that drops quiescent current below 20 nA in sleep mode. Key features include 7 KB (4K x 14) of self-programmable Flash, 192 bytes of RAM, an integrated LCD driver supporting up to 96 segments, a 14-channel 8-bit ADC with selectable references, and a nanoWatt XLP sleep current that enables multi-year battery life on a single coin cell. The 28-pin QFN (ML) package provides a compact footprint at 6x6 mm with an exposed thermal pad that lowers theta-JA and improves continuous high-I/O operation. Architecturally, the PIC16LF723 uses a 14-bit instruction word with an 8-bit data path, a two-stage pipeline, and a vectored interrupt controller with hardware context save/restore. The nanoWatt XLP block is built around an ultra-low-power bandgap reference and selectable on-chip oscillator modes (LF-INTOSC 31 kHz, HF-INTOSC 16 MHz, and external crystal), letting the firmware shift frequency dynamically to match workload and minimize dynamic dissipation. Typical applications include battery-powered sensor nodes, low-power remote controls, electronic shelf labels, thermostat and HVAC user-interface boards, metering front-ends with LCD displays, and ultra-low-power IoT edge nodes where the LCD driver eliminates a separate display controller. The wide 1.8V-5.5V supply range simplifies direct connection to alkaline, Li-coin, and single-cell Li-Ion chemistries. When designing with this part, place a 100 nF decoupling capacitor within 1-2 mm of VDD and a 10 uF bulk capacitor on the AVDD rail, and route the MCLR pin through a 10 kohm pull-up to VDD. Use the Microchip MPLAB X IDE with XC8 compiler for firmware development and program/debug via ICSP on PGED1/PGEC1.

PIC16LF723-I/SP

PIC16LF723-I/SP - 8-Bit 20MHz 7KB Flash MCU 28-SPDIP | Microchip

The Microchip PIC16LF723-I/SP is an 8-bit PIC16 family RISC microcontroller in a 28-pin SPDIP (Skinny Plastic DIP) tube package, featuring 7KB (4K x 14 words) of self-programmable Flash program memory and 192 bytes of RAM. It operates from 1.8V to 3.6V and supports instruction execution at up to 20MHz, delivering 200ns instruction cycle time. According to the Microchip product family description, the device is a member of the PIC XLP (eXtreme Low Power) family using nanoWatt XLP technology, which targets battery-powered and energy-harvesting designs. What is a PIC16 Microcontroller? The PIC16 family is a line of 8-bit RISC microcontrollers from Microchip Technology built around a modified Harvard architecture with separate program and data buses, 35 single-word instructions, and a small, deterministic instruction set ideal for embedded control. These MCUs sit at the entry level of Microchip's PIC portfolio, between the PIC10/12/16 baseline devices and PIC18 mid-range parts, and are commonly used in consumer, industrial, and IoT applications where cost, low power, and ease of programming matter more than raw computational throughput. Key features of the PIC16LF723-I/SP include 11 channels of 8-bit Analog-to-Digital Conversion (ADC), two PWM modules with Capture/Compare/PWM (CCP) capability, and three serial communication peripherals: I2C/SPI (master/slave SSP) and an enhanced USART. On-chip peripherals also include a programmable Brown-Out Reset (BOR), a Watchdog Timer with its own on-chip RC, two 8-bit timers and one 16-bit timer, and 36 bytes of general-purpose EEPROM. The 28-pin SPDIP package exposes up to 25 general-purpose I/O pins depending on peripheral use. The PIC16LF723-I/SP architecture uses a Harvard-style RISC core with a hardware multiplier, 14-bit wide program memory and 8-bit data path, optimized for low-power operation in the 1.8-3.6V range. Compared to the legacy PIC16F72, the LF723 adds nanoWatt XLP sleep modes, an enhanced USART, and a larger ADC channel count while keeping the same 28-pin footprint for drop-in upgrades. Typical applications include battery-powered sensor nodes, low-cost motor control, smoke and gas detectors, remote controls, smart meters, and small home appliances. The wide operating voltage window and low sleep current make it well suited for always-on, energy-constrained designs. When designing with this part, pay attention to the in-circuit serial programming (ICSP) pins and reserve adequate decoupling near VDD/VSS pairs; the LF variant is required for sub-2V operation, otherwise the standard PIC16F723 may be a lower-cost alternative.
