PIC16LF628AT-I/ML - 8-bit PIC MCU, 3.5KB Flash, 20MHz | Microchip

The Microchip Technology PIC16LF628AT-I/ML is an 8-bit PIC RISC microcontroller with 3.5 KB Flash program memory, 224 bytes RAM, and 128 bytes EEPROM, housed in a 28-pin QFN-EP (6x6 mm) package with exposed pad. It operates from 2.0V to 5.5V with a maximum clock rate of 20 MHz and 16 digital I/O pins, integrating a 10-bit ADC, two analog comparators, USART, and Capture/Compare/PWM modules for embedded control. A PIC microcontroller is a Harvard-architecture RISC MCU built around a small, deterministic instruction set optimized for low cost, low power, and fast interrupt response. PIC16F-series parts sit in the mid-range PIC family between baseline PIC10/12/16 and the high-performance PIC18/dsPIC families. They are widely used in consumer appliances, automotive body controllers, industrial sensors, and battery-powered IoT nodes where predictable real-time behavior, small footprint, and mature toolchains (MPLAB X, XC8) matter more than raw MIPS. Key features of the PIC16LF628AT-I/ML include 35 instructions, 8-level hardware stack, internal 4 MHz and 37 kHz oscillators, nanoWatt power-down modes, in-circuit serial programming (ICSP), and a wide -40C to +85C industrial temperature range. The internal oscillator eliminates external crystals in cost-sensitive designs, while the on-board EEPROM provides non-volatile user data storage without external memory. nanoWatt technology with multiple idle and sleep modes keeps quiescent current in the microamp range for battery applications. The architecture combines a RISC core with dedicated peripheral set: two analog comparators with programmable reference, 10-bit ADC up to 8 channels, 16 I/O with individual direction control, and a USART for asynchronous/synchronous serial. Capture, Compare, and PWM modules support motor control, signal timing, and lighting control. Self-programming under software control enables field firmware upgrades via the on-chip Flash memory. Typical applications include consumer remote controls, sensor interfaces, automotive body electronics, LED lighting drivers, security systems, small motor control, and general-purpose 8-bit embedded control. The exposed-pad QFN package suits space-constrained designs, while the industrial -40C to +85C range supports outdoor and automotive under-hood operating environments. When designing with this device, allocate adequate copper area under the exposed pad (EP) of the QFN package for thermal dissipation and provide 0.1uF ceramic bypass capacitors close to each power pin. Use MPLAB X IDE with the XC8 compiler and a PICkit programmer for development, and validate timing-critical ISRs against the instruction-cycle budget of the 20 MHz core.

PIC16LF628AT-I/SO

PIC16LF628AT-I/SO - 8-Bit 20MHz MCU, 3.5KB FLASH, 18-SOIC | Microchip

The Microchip PIC16LF628AT-I/SO is a flash-based 8-bit CMOS microcontroller from the PIC16F family, featuring a 20 MHz maximum operating frequency, 3.5 KB (2K x 14) of flash program memory, 224 bytes of SRAM, and 128 bytes of EEPROM data memory, all housed in an 18-pin SOIC wide-body surface-mount package. The 'LF' prefix denotes the low-power variant supporting an extended 2.0V to 5.5V operating range, making the part suitable for both 3.3V and 5V designs. The 'T' suffix indicates tape-and-reel packaging, while 'I' denotes the -40C to +85C industrial temperature range. An 8-bit microcontroller (MCU) is a programmable integrated circuit that integrates a CPU core, non-volatile program memory, volatile data memory, and configurable I/O peripherals onto a single silicon die. 8-bit MCUs occupy the entry-level tier of the embedded computing hierarchy - above fixed-function logic ICs but below 32-bit microcontrollers in arithmetic throughput. Within the PIC16 family specifically, the LF628A sits in the mid-range (14-bit instruction word) PIC16 tier, positioned between the smaller PIC12/PIC16F84A legacy parts and the more modern PIC16F1xxx enhanced mid-range devices. Its RISC-based Harvard architecture executes most instructions in a single clock cycle, giving it competitive code density per MHz compared with traditional CISC 8-bit cores. Key features include 16 I/O pins with individually configurable direction registers, an integrated 4 MHz internal oscillator (calibrable), two 8-bit timers plus one 16-bit timer, a 10-bit ADC-free analog comparator block, a USART for serial communication, and Microchip's nanoWatt Technology for sleep currents below 1 uA. The device supports in-circuit serial programming (ICSP) via two pins, enabling firmware updates without removing the part from the PCB. Code protection lock bits prevent unauthorized memory reads, and the watchdog timer with its own on-chip RC oscillator provides an independent recovery mechanism for software lockups. Typical applications include low-cost consumer appliance controllers, battery-powered remote sensors, hobbyist and educational development platforms, simple motor control loops, LED drivers, and replacement of legacy 8051 or PIC16F84A designs. The wide voltage range and nanoWatt sleep modes also support energy-harvesting designs where quiescent current directly determines battery life. Industrial designers favor the part for its long-term Microchip supply commitment and its mature, well-documented toolchain (MPLAB X, XC8 compiler, PICKit programmers). When designing with this part, observe the absolute maximum Vdd of 5.5V - exceeding this rating destroys the part. Use 100 nF decoupling within 5 mm of the Vdd pin and place the MCLR pull-up (typically 10 kohm) close to the pin to avoid spurious resets. The internal oscillator is factory-calibrated to within 1% of nominal, but for UART timing above 9600 baud, select the crystal oscillator mode and provide a 4x or higher baud-rate crystal.

Key features include a Harvard RISC architecture with 35 single-cycle instructions, an internal 4MHz oscillator (calibrated to ±1%), a hardware USART for serial communication, an analog comparator with two inputs, a capture/compare/PWM module, and nanoWatt Technology for ultra-low-power sleep currents as low as 100nA typical. The 20 MHz instruction rate delivers 5 MIPS of throughput, while 16 I/O pins each support independent weak pull-ups, interrupt-on-change, and digital-only or analog-comparator routing. The PIC16LF628A silicon integrates a precision 4 MHz internal RC oscillator, removing the need for external crystals in many designs. The on-chip comparator can generate interrupts, trigger timer capture, or wake the device from sleep. Brown-out reset (BOR) and power-on reset (POR) circuitry protect Flash integrity at low supply voltages, while the ICD2/ICD3 debug interface allows in-circuit programming and breakpoint debug through two reserved pins. Typical applications include remote control transmitters, sensor interface nodes, low-power battery sensor hubs, small appliance controllers, and hobby robotics. Its 2.0V minimum supply also suits single-cell lithium or two-AA-battery products where voltage headroom is constrained. When designing with this MCU, observe the 2.0V to 5.5V supply range and derate maximum Fosc above 4V (20 MHz @ 4V+; 4 MHz @ 2V). Reserve RA4/T0CKI and RA5/MCLR/VPP pin functions carefully, as they share I/O with programming/debugging functions. The 20-pin SSOP is a 0.65 mm pitch package that requires standard SMT reflow and inspection.

The Microchip PIC16LF628T-04/SS is an 8-bit RISC flash-based CMOS microcontroller delivering 4 MIPS performance at 4 MHz, housed in a 20-pin SSOP package with tape-and-reel packaging for high-volume assembly. It integrates 3.5 KB (2K x 14) of flash program memory, 224 bytes of SRAM, and 128 bytes of data EEPROM, while exposing 16 general-purpose digital I/O pins with individual direction control. The 'LF' prefix designates an extended low-voltage operating range of 2.0 V to 5.5 V, supporting both 3.3 V and 5 V designs from a single part number. An 8-bit microcontroller (MCU) is a single-chip computer built around an 8-bit data path that integrates a CPU core, program memory, data RAM, peripheral set, and I/O into one package. Within the broader taxonomy, an 8-bit MCU sits under microcontroller -> embedded processor -> semiconductor IC, and historically serves cost-sensitive, deterministic, low-power applications where ARM Cortex-M devices would be overkill. Key features include a Harvard RISC architecture with only 35 single-cycle instructions, an integrated analog comparator module with programmable on-chip voltage reference (VREF), two 8-bit timers plus one 16-bit timer, a USART with support for RS-232/RS-485 LIN, and a 10-bit (actually 8-bit PWM-capable) capture/compare/PWM module. The device also offers an internal 4 MHz oscillator, watchdog timer with on-chip RC oscillator, in-circuit serial programming (ICSP), and high-current sink/source capable of directly driving LEDs. Architecturally, the PIC16LF628 uses a 14-bit instruction word with separate program and data buses, allowing instruction fetch and data access to occur in the same clock cycle. The '04' speed grade specifies 4 MHz operation, while the 'T' suffix denotes tape-and-reel packaging, and '/SS' indicates the 20-lead SSOP package outline (5.30 mm body width, 0.65 mm pitch). Typical applications include battery-powered sensor nodes, automotive body controllers, appliance control boards, LED lighting controllers, hobbyist and educational embedded projects, industrial remote keyless entry (RKE), and small automation controllers. The wide voltage range makes it especially attractive for designs powered by 2x AA cells, coin cells, or unregulated supplies. When designing with this part, observe that PIC16LF628 requires MPLAB X IDE or older MPLAB 8 with Hi-Tech PICC or XC8 compiler for firmware development, and that the device shares the PIC16 mid-range instruction set with hundreds of family members, easing code portability. For new designs, evaluate whether a newer PIC16F1xxx enhanced mid-range device may offer better peripherals at similar cost.

The LF (low-power F) silicon supports a 2.0V to 5.5V supply window, enabling battery-friendly designs, and the device integrates 224 bytes of SRAM plus 128 bytes of data EEPROM for non-volatile parameter storage. The part suffix "-04" denotes the 4 MHz maximum oscillator, while "I" indicates the industrial -40C to +85C operating temperature range and "T" specifies Tape & Reel packaging. What is a PIC16 microcontroller? PIC16 is Microchip's mid-range 8-bit RISC microcontroller family built on a Harvard architecture with separate program and data buses. The 14-bit instruction word PIC16 core delivers deterministic instruction timing (most instructions execute in one instruction cycle), making PIC16 devices popular for cost-sensitive embedded control where predictable timing, low power, and small footprint outweigh the throughput of 32-bit cores. Key features include 16 digital I/O pins with individually programmable direction, two analog comparators with a programmable on-chip voltage reference, a USART for asynchronous/synchronous serial communication, one 8-bit and one 16-bit timer/counter, a PWM module, and a 10-bit ADC. Brown-out Reset (BOR), Power-on Reset (POR), and a Watchdog Timer with its own on-chip RC oscillator provide three layers of system safety. nanoWatt-style power management includes a low-power SLEEP mode and multi-frequency internal oscillator to reduce external component BOM. The PIC16LF628T-04 architecture pairs the mid-range CPU with Harvard-separated Flash and EEPROM, allowing in-application self-programming via ICSP. The internal comparator reference and dual analog comparators enable standalone signal conditioning without an external op-amp, while the USART, PWM, and capture/compare peripherals cover the classic embedded-control toolbox for motor, power-converter, and sensor-interface roles. Typical applications include low-power sensor nodes, automotive body and interior subsystems, HVAC fan/valve controllers, appliance user-interface boards, battery chargers, smart LED lighting controllers, and industrial telemetry outstations. The wide 2.0V-5.5V supply range suits 3.3V and 5V mixed-rail designs alike. When designing with the PIC16LF628T-04I/SO, reserve the OSC1/OSC2 pins carefully if you need an external crystal - the internal RC oscillator can free these pins for general I/O. Programming is via ICSP using PGEDT/RB7 and PGC/RB6; ensure these pins are not held low at reset or in-circuit programming is blocked.

The Microchip Technology PIC16LF648AT-I/ML is an 8-bit Flash microcontroller based on the enhanced PIC16 mid-range core, offering 7KB of program Flash, 256 bytes of RAM, and 16 digital I/O in a 28-pin QFN (6x6 mm) package with exposed thermal pad. It runs at up to 20 MHz, delivering 5 MIPS of throughput from a wide 2.0V to 5.5V supply, with the "LF" suffix indicating the low-power, low-voltage process variant optimized for battery-friendly designs. A microcontroller (MCU) is a single-chip computer that integrates a CPU, non-volatile program memory, working RAM, and a rich set of peripheral blocks (timers, ADC, comparators, communication modules) into one IC. PIC microcontrollers from Microchip sit in the broader category of 8-bit microcontrollers, which sit in turn under embedded microcontrollers, then microprocessors, and finally semiconductors. The 16F family is the workhorse "mid-range" PIC line, positioned between the 8-bit baseline PIC10/12/16F5xx and the 16-bit PIC24/dsPIC families. Key features of the PIC16LF648AT-I/ML include the on-chip USART for asynchronous/synchronous serial communication, a 10-bit ADC with up to 8 channels, two analog comparators, capture/compare/PWM modules for motor and LED control, an internal oscillator with software-tunable frequency, and an on-chip ICD debug interface for in-circuit programming. The 256-byte data EEPROM supports non-volatile parameter storage across power cycles, eliminating external storage ICs in many designs. Architecturally, the device uses a 14-bit instruction word RISC core with a hardware multiplier for fast math on byte and bit operations, a 2-stage pipeline allowing most instructions to execute in a single 200 ns cycle, and an enhanced flash program memory interface supporting self-programming and ICSP. Brown-out reset, power-on reset, and a programmable watchdog timer with its own on-chip low-power oscillator provide robust unsupervised operation in fielded systems. Typical applications include industrial sensor signal conditioning, low-power remote-control handsets, simple home appliances, battery chargers, motor and fan controllers, low-end digital thermostats, and automotive interior accessories (non-safety). The 28-QFN footprint suits compact handheld designs where board area is at a premium. When designing with this part, plan the trace layout to route the exposed thermal pad to a copper pour to keep the junction temperature within the industrial -40C to +85C operating range, since at 20 MHz the core draws several milliamps and the small QFN body has limited heat dissipation without the pad's copper area. Configure the configuration word carefully - especially the oscillator source, watchdog enable, and code-protect bits - because changing watchdog or oscillator settings later requires re-flow with a different binary.

A microcontroller (MCU) is a single-chip computer that integrates a CPU core, non-volatile program memory (Flash), volatile data memory (RAM), and a rich set of peripherals (ADC, timers, communication ports, I/O) into one package. PIC16LF devices sit within the 8-bit PIC microcontrollers -> 8-bit RISC microcontrollers -> microcontrollers -> embedded processors taxonomy, and they target ultra-low-power applications where extended battery life, capacitive touch, and small pin-count packages are mandatory. Key features include up to 16 MIPS throughput at 32 MHz instruction-cycle input, integrated capacitive-touch mTouch sensing hardware, multiple low-power sleep modes (nanowatt range) for battery-powered applications, an enhanced USART, MSSP for SPI/I2C, a 12-bit ADC with up to 14 channels, and CTMU for capacitive measurement. Compared with PIC16F variants, the LF family lowers core and I/O supply voltage to 1.8V, enabling direct Li-ion/Li-Po battery operation. Typical applications include capacitive touch key panels for white goods and consumer appliances, low-power handheld medical devices, IoT sensor nodes with touch-based wake, automotive body and HVAC controls, and capacitive proximity/metal-overlap detection modules. The 44-VQFN exposed pad improves thermal dissipation and reduces PCB footprint versus 44-pin TQFP. Designers should observe the exposed-pad PCB layout requirements of the VQFN: a contiguous ground pad, multiple thermal vias, and a 0.1uF plus 10uF decoupling network placed within millimetres of the supply pins are mandatory for brown-out-free start-up.

The PIC16LF72's combination of small package footprint, integrated analog and serial peripherals, and low-voltage operation makes it a popular choice when a full PIC16 mid-range MCU is not required. A key design consideration is the ADC acquisition-time and source-impedance budget: with a recommended source impedance below 10 kohm, an external op-amp buffer may be required when reading high-impedance sensors. Designers should also place a 0.1 uF decoupling capacitor within 5 mm of VDD and route analog/digital grounds back to a single star point to minimize conversion noise.

PIC16LF720-E/ML - 8-Bit 16MHz MCU, 3.5KB Flash, 20-QFN | Microchip

The Microchip Technology PIC16LF720-E/ML is an 8-bit PIC microcontroller featuring a 16MHz internal oscillator, 3.5KB (2K x 14 words) of self-read/write Flash program memory, 128 bytes of SRAM, and 36 I/O pins (18 functional I/O), packaged in a 20-lead QFN (4x4 mm) with an exposed thermal pad. It operates from a 2.3V to 3.6V supply, includes nanoWatt XLP ultra-low-power technology, and provides I2C, SPI, and AUSART (UART) connectivity along with CCP/PWM, 12-channel 8-bit ADC, brown-out reset, watchdog timer, and power-on reset peripherals. A microcontroller (MCU) is a single-chip computer that integrates a CPU, memory, and programmable I/O peripherals. The PIC16F/LF720 belongs to Microchip's mid-range PIC16 family, which sits between the baseline 8-bit PIC10/12/16 cores and the high-performance PIC18/dsPIC families. Mid-range PIC16 parts use a 14-bit instruction word with 35 instructions, providing a balance of code density, deterministic timing, and low power consumption that makes them popular for cost-sensitive embedded applications. Key features of the PIC16LF720 include its nanoWatt XLP technology, which delivers sleep currents down to the nanoampere range, making the part suitable for battery-powered designs with multi-year standby requirements. The 25mA source/sink capability on I/O pins allows direct drive of LEDs and small relays without buffering. Internal 16MHz oscillator accuracy eliminates the need for an external crystal in most applications, reducing BOM cost and PCB area. Typical applications include consumer electronics, remote controls, sensor interfaces, low-power wireless nodes, home appliances, and industrial control subsystems where 8-bit processing, low power, and small footprint are essential. The PIC16LF720 prefix (LF) denotes the low-voltage (2.3V-3.6V) variant, while the F720 prefix (without LF) covers the wider 1.8V-5.5V part. The /ML suffix indicates the 20-QFN package. When designing with this MCU, ensure decoupling capacitors are placed close to VDD and the exposed pad is soldered for proper thermal dissipation and ground connection. For applications requiring more than 3.5KB of code, evaluate PIC16F721 (7KB Flash) or PIC16F1933 (enhanced mid-range core) as migration paths within the same footprint family.

PIC16LF720-E/P - 8-Bit 16MHz MCU, 3.5KB Flash, 20-PDIP | Microchip

The Microchip Technology PIC16LF720-E/P is an 8-bit PIC microcontroller featuring a 16MHz CPU core, 3.5KB (2K x 14 words) of Flash program memory, and a 20-pin PDIP through-hole package designed for the low-voltage (LF) supply range. It belongs to the PIC16 (L)F720/721 family of 20-pin Flash MCUs with NanoWatt XLP Technology, engineered for low-power embedded applications. A microcontroller (MCU) is a single-chip computer that integrates a CPU, memory (Flash/RAM/EEPROM), and peripherals on one die. Within the embedded hierarchy, MCUs sit below microprocessors (MPUs) and above discrete logic in the system architecture. The PIC16 family uses a Harvard-architecture RISC core with a 14-bit instruction word, well known for deterministic execution and a compact, easy-to-learn instruction set. The "LF" prefix designates the low-voltage variant operating from 2.3V to 3.6V, while the "F720" part number identifies the 20-pin device with NanoWatt XLP (eXtreme Low Power) technology. Key features of the PIC16LF720-E/P include 128 bytes of RAM, 256 bytes of EEPROM data memory, up to 18 digital I/O pins, an enhanced USART, MSSP (SPI/I2C), two 8-bit timers, one 16-bit timer, a 12-bit ADC with up to 12 channels, and a 5-bit DAC. XLP technology enables sleep currents below 1 microampere, and the device supports multiple low-power wake events including interrupt-on-change, timer overflow, and peripheral triggers. The 20-pin PDIP package offers a through-hole footprint that simplifies breadboarding, hand-soldering, and legacy board designs. The -E suffix indicates the Extended operating temperature range of -40C to +125C, qualifying the device for industrial and harsh-environment applications. Internal oscillator options support up to 16MHz without an external crystal, reducing BOM cost and PCB area. Typical applications include battery-powered sensor nodes, low-power IoT edge devices, consumer remote controls, simple motor control loops, LED lighting controllers, and industrial automation peripherals where the through-hole PDIP package and extended temperature range are advantageous. Designers should configure the configuration bits (CONFIG) for oscillator selection, watchdog timer, low-voltage programming, and code protection prior to programming. The ICSP (In-Circuit Serial Programming) interface shares pins with PGED/PGEC, which must be reserved on the PCB.

PIC16LF720-E/SS

PIC16LF720-E/SS - 8-Bit MCU, 16MHz, 3.5KB Flash, 20-SSOP | Microchip

The Microchip Technology PIC16LF720-E/SS is a low-power 8-bit PIC microcontroller built on the mid-range RISC core with 35 instructions, delivering 16 MIPS at 16 MHz from a 3.5 KB (2K x 14) self-read/write Flash program memory, packaged in a 20-pin SSOP. It targets battery-friendly embedded designs with Microchip's nanoWatt XLP technology, 128 B SRAM, and a wide 1.8 V to 3.6 V operating range. An 8-bit microcontroller (MCU) is a single-chip computer that integrates a CPU, non-volatile program memory, volatile data memory, and peripherals around an 8-bit data path. PIC mid-range MCUs sit within Microchip's broader family of 8-bit microcontrollers (PIC10/12/14/16/18) under the larger umbrella of microcontrollers, embedded controllers, and finally semiconductors. Engineers select the PIC16LF720 family when they need low active and sleep current, deterministic interrupt latency, and on-chip peripherals like ADC, I2C, SPI, AUSART, and CCP in a small-footprint surface-mount package. Key features include 18 I/O pins with 25 mA source/sink capability, 12-channel 8-bit ADC, two 8-bit timers (TMR0/TMR2) plus one 16-bit timer (TMR1), an internal 16 MHz oscillator, and nanoWatt XLP sleep currents that make the part suitable for coin-cell and energy-harvesting applications. The E temperature grade extends the operating range from -40 C to +125 C, qualifying the device for industrial and automotive-adjacent environments. The architecture relies on a Harvard-style RISC engine with 8 stack levels, hardware-accelerated interrupt context saving, and a self-programmable Flash that supports in-circuit serial programming (ICSP). The internal oscillator eliminates an external crystal in many designs, reducing BOM cost and PCB area while the WDT, POR, and BOR improve system robustness during brown-out and code-runaway events. Typical applications include low-power sensor nodes, battery-powered consumer devices, automotive interior modules, industrial control subsystems, and USB-to-UART bridges using the AUSART peripheral. The 128 B SRAM and 3.5 KB Flash are sized for compact state machines, sensor fusion pre-processing, and protocol translation firmware. When designing with this part, choose the LF (low-voltage F) variant when VDD stays under 3.6 V, and pair the device with a 0.1 uF + 10 uF decoupling network near VDD. Programming via ICSP requires the standard PGD/PGC/VDD/VSS/MCLR/RB6/RB7 connections, so leave those test points accessible during layout review.
