PIC16LF722A-I/ML - 8-bit MCU 3.5KB Flash 28-VQFN | Microchip

The Microchip Technology PIC16LF722A-I/ML is an 8-bit PIC microcontroller based on the enhanced mid-range core, featuring 3.5 KB (2K x 14 words) of Flash program memory and 128 bytes of RAM, housed in a 28-pin VQFN package with exposed thermal pad. It operates from 1.8V to 3.6V supply, runs at up to 20 MHz instruction rate, and integrates nanoWatt XLP (eXtreme Low Power) technology for battery-friendly designs. Per Microchip datasheet 41391E, the part belongs to the PIC16F/LF722A/723A family of 28-pin Flash microcontrollers aimed at compact, low-power embedded applications. A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory (Flash/ROM), data memory (RAM), and peripherals such as timers, ADC, communication interfaces, and I/O ports. The PIC16LF722A sits inside the 8-bit MCU taxonomy (MCU -> microcontroller -> embedded controller -> semiconductor). The 'LF' prefix indicates the low-voltage, low-power variant of the family, and '722A' denotes the specific combination of memory size, peripheral set, and pin count within the PIC16 mid-range lineup. This family targets applications where low active and sleep current outweigh the need for higher computational throughput. Key features include 11 ADC channels with 8-bit resolution, one 8-bit and two CCP modules, an Enhanced USART, an MSSP module supporting SPI and I2C (master/slave), two 8-bit timers plus one 16-bit timer, and 24 GPIO lines. Internal 16 MHz and 31 kHz oscillators reduce BOM cost, and the device supports in-circuit serial programming (ICSP) plus in-circuit debugging. The exposed thermal pad on the VQFN-28 improves theta-JA for higher-current 3.3V rails. Architecturally, the PIC16LF722A uses a 14-bit instruction word with an 8-level hardware stack, providing predictable deterministic execution suited to interrupt-driven control loops. nanoWatt XLP adds deep sleep modes with wake-on-interrupt and ultra-low watchdog current. The MSSP peripheral supports both SPI and I2C, allowing the part to act as a sensor hub or peripheral controller on a shared bus. Typical applications include battery-powered sensor nodes, IoT edge devices, low-power wireless remote controls, consumer appliances, LED lighting controllers, and small motor/temperature control loops. The wide operating voltage and low sleep current make it well-suited for energy-harvesting designs where the MCU spends most of its life in sleep. When designing with this part, choose decoupling per the datasheet (e.g., 0.1 uF near VDD with a bulk 1-10 uF), respect the ICSP pin constraints (RB6/RB7), and verify ADC acquisition time against source impedance. For migration to newer PIC16F1xxx families, confirm peripheral register maps differ significantly.

Key features include 128 bytes of RAM, 256 bytes of EEPROM, 25 I/O pins, an internal 16MHz oscillator, and an operating voltage range of 1.8V to 3.6V. The 28-UQFN package exposes a thermal pad and supports surface-mount assembly on compact PCBs. The device integrates multiple peripherals commonly needed in mixed-signal embedded designs: ADC, comparators, PWM modules, USART, MSSP (SPI/I2C), and timers. Typical applications include low-power IoT sensor nodes, battery-powered remote controls, consumer white goods user interfaces, and compact industrial sensor conditioning. The wide 1.8V-3.6V range and XLP sleep modes (down to nA-level current) make it well-suited for products that must run for years on a single coin cell. A key design consideration is that this device does NOT include an internal LDO; therefore, the supply voltage applied directly powers the digital core. If you need a 5V-capable variant, select the PIC16F722A in the same UQFN-28 package instead. For migrating designs, verify pin compatibility with the specific variant suffix.

The Microchip Technology PIC16LF722A-I/SO is an 8-bit PIC mid-range microcontroller with 3.5KB Flash program memory (2K x 14), packaged in a 28-pin SOIC (300 mil). It operates from a 1.8V to 3.6V supply with up to 20MHz CPU clock, and is part of Microchip's nanoWatt eXtreme Low Power (XLP) technology family. What is a PIC16 microcontroller? 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. Key features of the PIC16LF722A-I/SO include: 128 bytes of EEPROM data memory, 128 bytes of SRAM, 25 digital I/O pins, a 12-channel 8-bit ADC, two 8-bit timers and one 16-bit timer, one enhanced CCP module, one USART, and a 16MHz internal oscillator. The nanoWatt XLP technology keeps active current in the microamp range and sleep current under 100 nA typical — critical for battery-powered sensor nodes. Master Clear Reset, internal pull-ups, and an in-circuit serial programming (ICSP) interface simplify prototyping. Architecturally the device uses a Harvard RISC core with a 14-bit instruction word, 8-deep hardware stack, and direct/indirect addressing modes. The 35-instruction set accelerates deterministic real-time control, while the integrated 16MHz internal oscillator removes the external crystal in many designs, reducing BOM cost and saving board area. Typical applications include battery-powered IoT sensor nodes, home-automation peripherals, low-cost consumer appliances, remote controls, wearable accessories, and small industrial control modules. The combination of 25 I/O, 12-channel ADC, USART, and nanoWatt XLP makes it well-suited to single-chip sensor read-and-transmit nodes. When designing with the PIC16LF722A-I/SO, ensure decoupling caps (100nF plus 10uF) sit within 5 mm of VDD/AVDD/VSS, and route the ICSPDAT/ICSPCLK lines away from switching nodes. The internal 16MHz oscillator is accurate to ±1% after factory calibration but degrades over temperature — choose an external crystal for protocols such as UART at higher baud rates.

The nanoWatt XLP technology delivers sleep currents as low as [DATA_NEEDED: exact nA sleep current], and watchdog timer, brown-out reset, and power-on reset are integrated. The 28-SSOP package with 0.65 mm pitch provides a compact footprint for space-constrained PCB designs. Internally the PIC16LF722A uses an enhanced mid-range 14-bit instruction set with a hardware multiplier, 32 kHz internal oscillator, and configurable oscillator options (HFINTOSC, LFINTOSC, external crystal, external RC). The integrated ICSP (In-Circuit Serial Programming) header supports in-field firmware updates without removing the MCU from the board, which simplifies manufacturing and field service. Typical applications include battery-powered sensor nodes, wearable fitness bands, remote controls, low-cost IoT edge nodes, small home appliances, and industrial sensor conditioning. Its low-power architecture makes it well suited for energy-harvesting designs and products powered by coin-cell or alkaline batteries.

Architecturally, the PIC16LF722AT uses a Harvard RISC core with a fixed 14-bit instruction word, dual-cycle branch, and a vectored interrupt structure. The internal oscillator trimming and PLL deliver accurate baud-rate generation for asynchronous serial links, while the nanoWatt XLP power-management unit tracks dynamic current vs. clock speed and wakes the CPU in a single oscillator cycle from deep sleep. Temperature range is -40 C to +85 C (Industrial grade). Typical applications include low-power sensor nodes, battery-powered remote controls, consumer white goods, IoT edge devices, medical wearables, and industrial control panels where the small UQFN footprint enables dense board layouts. The combination of 3.5 KB Flash and 20 MHz performance is sufficient for state-machine control, simple protocol bridging, and user-interface tasks. When designing with the PIC16LF722AT, ensure the exposed thermal pad is soldered to a continuous ground plane to meet thermal dissipation and provide a low-impedance return for the ADC. The internal oscillator calibration bits in CONFIG should be left at factory defaults unless the application specifically requires a non-standard Fosc.

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.

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.

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.

PIC16LF723AT-I/SS - 8-bit 20MHz MCU 7KB Flash XLP | Microchip

The Microchip Technology PIC16LF723AT-I/SS is an 8-bit RISC microcontroller built on the PIC16 core with nanoWatt XLP (eXtreme Low Power) technology, offering 7KB (4K x 14) of Flash program memory, 192 bytes of data RAM, and operation up to 20MHz in a 28-pin SSOP package. It operates from a wide 1.8V to 3.6V supply (Low-F variant) and includes an integrated 16MHz internal oscillator, making it suitable for low-power and battery-driven embedded designs. The IC uses surface-mount SSOP-28 packaging and ships in Tape & Reel format (T suffix). An 8-bit microcontroller (MCU) is a single-chip computer that integrates a CPU, program memory (Flash), data memory (RAM), and peripherals such as timers, ADC, communication interfaces, and I/O pins on one die. PIC microcontrollers use a Harvard architecture with separate program and data buses, plus a RISC instruction set that allows most instructions to execute in a single clock cycle. Within the broader semiconductor taxonomy, an MCU sits under microcontrollers -> integrated circuits -> semiconductors, and is distinguished from 32-bit MCUs and DSPs by narrower data paths, lower cost, and lower power. Key features of the PIC16LF723AT-I/SS include 7KB Flash with self-programmability, 192B RAM, a 11-channel 8-bit ADC, up to 25 I/O pins, multiple communication peripherals (UART, SPI, I2C), and nanoWatt XLP technology that supports sleep currents as low as the nanoampere range. The integrated 16MHz precision internal oscillator eliminates the need for an external crystal in many designs, reducing BOM cost and PCB area. The 28-SSOP package provides a compact 0.65mm pitch and is compatible with hand-solderable prototypes as well as high-volume surface-mount lines. Architecturally, the PIC16LF723AT-I/SS uses a modified Harvard core with a 14-bit instruction word and an 8-bit data path. The 20MHz maximum clock delivers up to 5 MIPS of throughput. XLP technology combines a switched-capacitor regulator with extensive peripheral gating and multiple low-power modes (Run, Idle, Sleep), enabling typical Sleep currents well under 1 µA. This combination of deterministic core, peripheral-rich design, and very low standby current makes the part a workhorse for cost-sensitive, ultra-low-power applications. Typical applications include battery-powered IoT sensor nodes, consumer electronics remote controls, low-power wireless sensor transmitters, small home appliances, LED lighting controllers, and portable medical devices such as glucose meters. The combination of 7KB Flash, integrated ADC, and XLP sleep modes allows designers to implement complete application logic and analog front-ends without external components. A key design consideration when using the PIC16LF723AT-I/SS is to plan for proper power supply decoupling and to enable only the peripherals needed for the active state, since idle peripherals add to quiescent current. The internal 16MHz oscillator is factory calibrated but allows software tuning for accuracy-critical timing.
