PIC16LF627A-I/P - 8-Bit 20MHz Flash MCU 1.75KB | Microchip

The Microchip Technology PIC16LF627A-I/P is an 8-bit Flash-based CMOS microcontroller in the PIC16 mid-range family, offering 1.75KB (1K x 14) of Flash program memory, 224 bytes of SRAM, and 128 bytes of EEPROM data memory. Operating at up to 20MHz instruction clock from a 2.0V to 5.5V supply, the device is housed in a 18-pin PDIP through-hole package, making it ideal for breadboard prototyping, education, and legacy designs. The 'LF' suffix denotes the extended low-voltage variant, the 'A' revision adds internal oscillator improvements and USART support, the 'I' indicates the industrial temperature grade of -40C to +85C, and the '/P' package designator specifies the plastic DIP form factor. A PIC16 mid-range microcontroller is a class of 8-bit RISC MCU built around a 14-bit instruction word and a Harvard architecture with separate program and data buses. The PIC16 LF family sits within the broader PIC microcontrollers -> 8-bit microcontrollers -> microcontrollers -> microcontrollers IC hierarchy and is targeted at low-power, cost-sensitive embedded designs where deterministic interrupt response and ease of programming outweigh raw MIPS. Compared to 32-bit Cortex-M parts, PIC16F/LF devices trade raw throughput for ultra-low power, simpler toolchains, and decades of stable code libraries. Key features include a 4MHz internal oscillator (selectable), a USART module for asynchronous serial communication, a Capture/Compare/PWM (CCP) peripheral, two analog comparators with a programmable voltage reference, 16 I/O pins with weak pull-ups, a Watchdog Timer with its own on-chip RC oscillator, Brown-out Detect (BOD), Power-on Reset (POR), Power-up Timer (PWRT), and an Oscillator Start-up Timer (OST). The 14-bit instruction width and 35 single-word instruction set make firmware development and code reuse straightforward across the PIC16 family. The PIC16LF627A-I/P is well suited to low-power applications such as battery-powered sensor nodes, simple motor control, remote controls, and consumer white goods. The internal oscillator eliminates external crystals in many designs, reducing BOM cost and board space. The device's nanoWatt-class sleep modes and low-voltage operation (down to 2.0V) extend battery life in always-on or duty-cycled systems. Typical applications include hobbyist electronics, automotive interior accessories (non-safety), industrial sensor interfaces, and educational platforms where the 18-pin DIP form factor enables easy insertion into breadboards and ZIF sockets. When designing with this MCU, ensure decoupling capacitors are placed close to VDD/VSS pins, and reserve the MCLR pin for either an external reset or an internal weak pull-up configuration.

PIC16LF627A-I/SO

PIC16LF627A-I/SO - 8-bit MCU 1.75KB Flash 20MHz SOIC-18 | Microchip

The Microchip Technology PIC16LF627A-I/SO is an 8-bit flash-based CMOS microcontroller (MCU) delivering 20 MHz instruction execution from 1.75 KB of program memory (1K x 14 words) and 224 bytes of RAM, housed in an 18-pin SOIC (SO) package. It is the low-voltage (LF) variant of the PIC16F627A family, targeting applications with 2.0V to 5.5V rails. An 8-bit microcontroller (MCU) is a single-chip computer with an 8-bit data path, on-board program memory (Flash/ROM), CPU, RAM, and peripherals (timers, USART, ADC, comparators, GPIO). It sits in the embedded-control hierarchy: microcontroller -> microprocessor -> semiconductor -> integrated circuit. The PIC16F627A family uses Microchip's RISC instruction set with only 35 single-word instructions, 200 ns instruction cycle at 20 MHz, and upwards code compatibility with PIC16F627, PIC16C62XA, PIC16C5X, and PIC12CXXX devices, simplifying migration paths. Key features include a 4 MHz internal RC oscillator (selectable to 48 kHz LF), 128 bytes of EEPROM data memory, 16 digital I/O lines, a USART module, one capture/compare/PWM (CCP) module, two analog comparators with programmable voltage reference, a watchdog timer with its own RC oscillator, brown-out detect (BOD), power-on reset (POR), power-up timer (PWRT), and oscillator start-up timer (OST). Programmable weak pull-ups on PORTB and weak pull-ups on PORTB reduce BOM cost. The architecture separates program Flash from data EEPROM, allowing in-application re-programming without disturbing live data. The LF suffix extends VDD operation down to 2.0V (versus 2.0V-5.5V for the F version), making this MCU suitable for battery-backed and 3.3V-only designs. The 18-pin SOIC package offers 31.6 C/W typical theta-JA, adequate for industrial-temperature environments (-40C to +85C for the I suffix). Typical applications include low-cost industrial control nodes, sensor signal conditioning with on-chip comparators, low-speed UART bridges, hobbyist/educational projects, and battery-powered instrumentation where the LF core reduces quiescent draw. When designing, note that the LF core's 2.0V minimum VDD rules out 5V-only peripherals; choose the F (PIC16F627A) variant if 2.0V-5.5V is acceptable but you may occasionally drop to 4.5V. Decouple VDD with 0.1 uF + 10 uF ceramics placed within 5 mm of the pins.

It integrates a 20 MHz internal oscillator, an enhanced 14-bit instruction set, nanoWatt XLP power-management technology, and a USART/SCI interface for asynchronous serial communication, with a wide 2.0 V to 5.5 V supply range ideal for battery-powered designs. The 'LF' (Low-power / Low-voltage F) suffix denotes a 2.0 V minimum operating voltage and enhanced power-saving modes, while the 'T' suffix indicates Tape & Reel packaging and the 'I' code designates the industrial temperature grade (-40 C to +85 C). A microcontroller (MCU) is a single-chip computer that integrates a CPU, RAM, non-volatile program memory (Flash/ROM), I/O peripherals, and often communication interfaces into one package. The PIC16F family of microcontrollers uses a RISC architecture with a small instruction set and one accumulator (W register), providing deterministic timing and low power consumption across simple embedded control tasks. Within the broader IC taxonomy, an MCU belongs to: microcontroller -> embedded processor -> integrated circuit -> semiconductor. The 'F' suffix specifically indicates Flash-based (re-programmable) program memory, distinct from older one-time-programmable (OTP) and ROM-only variants. Key features of the PIC16LF627AT-I/SO include up to 16 digital I/O pins (15 of which are general-purpose), two analog comparators with rail-to-rail inputs, a capture/compare/PWM (CCP) module, a 5-channel 10-bit ADC, and nanoWatt XLP technology with sleep currents typically below 1 uA. Internal peripherals also include a programmable Brown-Out Reset (BOR), Power-On Reset (POR), Watchdog Timer with on-chip oscillator, and a universal synchronous/asynchronous receiver/transmitter (USART). The high-performance 14-bit RISC core executes most instructions in one instruction cycle (200 ns at 20 MHz) and provides 35 single-word instructions plus 14-bit instructions for direct table reads. Architecturally, the PIC16LF627A family separates program and data memory (Harvard architecture) and supports self-programmability under software control. The device is supported by Microchip's MPLAB X IDE, MPLAB XC8 C compiler, and an extensive library of application notes and reference designs that demonstrate typical usage for motor control, sensor interfaces, and low-power remote-control nodes. Field updates are simplified by the ICSP (In-Circuit Serial Programming) interface, which uses only two pins (RB6 and RB7). Typical applications for the PIC16LF627AT-I/SO include remote control transmitters, IR/RF receiver front-ends, battery-powered sensor interfaces, simple motor-speed controllers, and white-goods/HVAC user-interface panels. Its compact 18-pin SOIC footprint and low power consumption make it suitable for cost-sensitive, space-constrained designs that still need on-chip peripherals such as ADC, comparators, and USART. When designing with this MCU, consider that the internal 4 MHz and 20 MHz oscillators can drift with temperature and supply voltage; choose the external crystal mode if your UART timing or ADC sampling budget is tight. Always validate BOR and POR behavior in low-voltage battery designs, since the LF variant has a 2.0 V minimum operating point.

PIC16LF628-04I/SS - 8-Bit 4MHz PIC MCU, 3.5KB Flash | Microchip

The Microchip Technology PIC16LF628-04I/SS is an 8-bit Flash-based CMOS microcontroller from the PIC16F family, operating at up to 4 MHz instruction rate from a 2.0–5.5 V supply and packaged in a 20-pin SSOP (5.30 mm body, 0.65 mm pitch). It integrates 3.5 KB (2K × 14) of Flash program memory, 224 bytes of RAM, and 128 bytes of EEPROM, with 16 general-purpose digital I/O pins, two analog comparators with programmable on-chip voltage reference, a USART, and a Capture/Compare/PWM (CCP) module. A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program and data memory, I/O peripherals, and clock/timer subsystems into one package. PIC16 series microcontrollers use Microchip's enhanced mid-range RISC Harvard architecture with a 14-bit instruction word optimized for deterministic, single-cycle execution of most opcodes, making the family well-suited for compact, low-power embedded control. The 'LF' prefix denotes an extended-voltage variant covering 2.0–5.5 V, and the 'I' suffix indicates the industrial temperature range (-40 °C to +85 °C). Key features of the PIC16LF628-04I/SS include an internal 4 MHz RC oscillator (calibrated to ±1%), a Watchdog Timer with its own on-chip RC oscillator, Brown-out Detect (BOD), Power-up Timer (PWRT) and Oscillator Start-up Timer (OST) for reliable reset behavior, programmable weak pull-ups on PORTB, and an ICSP™ (In-Circuit Serial Programming) interface. The device supports sleep mode with wake-on-change I/O for battery-friendly operation, and each I/O pin can source/sink up to 25 mA for direct LED drive. Architecturally the part provides two 8-bit timers (Timer0, Timer2) and one 16-bit timer (Timer1), a 10-bit resolution PWM channel, and an internal voltage reference programmable for the comparator module. These resources make the device a strong fit when designers need more analog and serial capability than the PIC12/PIC16F627 baseline offers, but do not need the ADC peripheral or larger Flash of the PIC16F88/PIC16F88A family. Typical applications include appliance control boards, sensor signal conditioning front-ends, low-cost motor/relay drivers, LED lighting controllers, automotive body electronics (non-safety), remote controls, and battery-powered instruments. With 16 I/O, a USART, and two analog comparators, the part bridges the gap between the smaller PIC16F627 and the larger PIC16F88A in cost-sensitive 20-pin designs. A key design consideration is supply decoupling: place a 0.1 µF ceramic bypass capacitor within 5 mm of VDD, and add a bulk capacitor (≥10 µF) on the main rail. The MCLR pin must be tied to VDD through a 10 kΩ pull-up unless ICSP is used, in which case the standard ICSP circuit applies. Avoid leaving unused I/O pins floating — configure them as outputs or enable the internal weak pull-ups to minimize current consumption in sleep.

Typical applications include remote controls, sensor interface modules, small motor/relay drivers, low-end security keypads, hobby robotics, and battery-powered instrumentation where the wide 2.0-5.5 V supply simplifies single-cell Li-ion or 2x AA design. The 28-QFN (ML) footprint also enables compact PCB layouts in space-constrained consumer and IoT nodes. When designing with this part, allocate the 16 GPIO wisely - several pins are multiplexed with the ADC, comparators, oscillator and the ICP/CCP/peripheral functions. Place decoupling on VDD/AVDD/VSS/AVSS, follow Microchip's QFN-6x6 land pattern for thermal relief, and use ICD/ICSP headers for in-circuit debug. This page combines distributor pricing, drop-in 28-QFN alternatives, and design notes to give a faster path to a BOM decision than the manufacturer datasheet alone.

PIC16LF628A-I/P

PIC16LF628A-I/P - 8-Bit 20MHz Flash MCU 3.5KB | Microchip

The Microchip Technology PIC16LF628A-I/P is an 8-bit RISC PIC16 family microcontroller featuring 3.5KB (2K x 14) of Flash program memory, 224 bytes of SRAM, and 128 bytes of EEPROM data memory, housed in a 18-pin PDIP (0.300 inch, 7.62mm) through-hole package. It executes instructions in a 200 ns cycle time (20 MHz oscillator) and operates from 2.0V to 5.5V with nanoWatt technology for ultra-low-power sleep modes. An 8-bit microcontroller (MCU) is a small computing system on a single integrated circuit that integrates a CPU, RAM, Flash program memory, EEPROM, timers, and peripherals such as ADC, UART, and GPIO. PIC microcontrollers follow the RISC (Reduced Instruction Set Computer) philosophy with only 35 single-word instructions, simplifying code generation in assembly or C (XC8). The PIC16 family sits between the baseline PIC10/12/16 series and the enhanced PIC18/dsPIC families in the Microchip 8-bit hierarchy, making it a workhorse for cost-sensitive embedded designs. Key features include 16 digital I/O pins capable of driving LEDs directly, two analog comparators with programmable on-chip reference, a USART module for serial communication, capture/compare/PWM (CCP) modules, and three timers (Timer0, Timer1, Timer2). The internal 4 MHz oscillator eliminates the need for an external crystal in many designs, while the internal 48 kHz LF oscillator enables the nanoWatt sleep modes drawing only nA-level standby current. Architecturally, the PIC16LF628A uses a Harvard bus structure with separate code and data paths, a 14-bit instruction word, and 8-bit data paths. The 'LF' variant supports the wide 2.0V to 5.5V operating range needed for battery-powered designs, distinguishing it from the PIC16F628A which is specified 2.0V to 5.5V with different Flash endurance and voltage characteristics. The part is fully software- and pin-compatible with the PIC16F628A, the PIC16C62XA, the PIC16C5X, and the PIC12CXXX families. Typical applications include appliance controls, hobby and educational projects, sensor signal conditioning, low-power remote controls, automotive body electronics, and any cost-sensitive embedded node requiring Flash reprogrammability. Designers choose it when 14-bit PIC instruction set familiarity, broad third-party tool support, and wide memory headroom for firmware updates matter. When designing, ensure the MCLR pin is pulled high through a 10 kohm resistor for normal run mode and consider using the internal oscillator with a 100 nF decoupling capacitor at VDD to suppress digital switching noise from corrupting the analog comparator reference. The CCP and USART peripherals share pins in some configurations, so re-read the pin allocation table before committing to a board layout.

The 18-pin SOIC package is industry-standard and supports both hand-soldering and reflow manufacturing. The PIC16LF628A uses an enhanced mid-range 14-bit instruction core with hardware multiply, interrupt context save/restore, and In-Circuit Serial Programming (ICSP) via two pins. It is upward source-compatible with PIC16F628, PIC16C62XA, PIC16C5X, and PIC12CXXX devices, enabling easy migration and reuse of legacy code. The flash program memory supports 100K erase/write cycles typical and 40-year data retention. Typical applications include consumer electronics remote controls, battery-powered sensor nodes, automotive body and interior modules, small appliance motor control, security and alarm system keypads, and industrial control logic. The wide 2.5V-5.5V supply range makes it well suited for 3.3V and 5V mixed-voltage designs. Design consideration: ensure decoupling capacitors (100 nF ceramic plus 10 uF bulk) are placed within 5 mm of the VDD pin and that unused I/O pins are configured as outputs with low level to minimize sleep current. Designers should also budget for the 128 bytes of EEPROM write endurance (100K cycles typical) when designing parameter storage subsystems.

PIC16LF628A-I/SS - 8-bit Flash MCU 3.5KB 224B RAM SSOP-20 | Microchip

The Microchip Technology PIC16LF628A-I/SS is an 8-bit Flash-based CMOS microcontroller from the PIC16 family (PIC16F6XX series), built on Microchip's RISC architecture with nanoWatt power management technology, delivered in a 20-pin SSOP (Shrink Small Outline Package, 0.300 inch body width) for surface-mount assembly. It integrates 3.5 KB of program memory, 224 bytes of RAM, and 128 bytes of data EEPROM, executes instructions at 200 ns per cycle from a 20 MHz external clock, and offers 16 digital I/O pins plus a hardware USART, internal 4 MHz oscillator, and a 10-bit ADC-less analog comparator for analog signal conditioning. The "LF" prefix denotes an extended low-voltage operating range of 2.0V to 5.5V, with active supply currents below 100 µA/MIPS in real-world firmware profiles thanks to nanoWatt sleep, run, and idle modes. An 8-bit microcontroller (MCU) is a single-chip computer with an 8-bit data path, integrating a CPU, non-volatile program memory (Flash), volatile data RAM, non-volatile data EEPROM, and peripheral IP such as timers, USART, ADC, comparators and I/O pins. PIC16F microcontrollers belong to the wider class of RISC microcontrollers -> microcontrollers -> embedded processors -> semiconductors, sitting beneath 32-bit Cortex-M parts in compute power but above bare timer/logic ICs in programmable flexibility. They are typically deployed for state-machine control, sensor conditioning, and protocol bridging in cost-sensitive 5V/3.3V designs. Key differentiating features include 35 single-word instructions for easy programming in MPLAB X IDE, ICSP (In-Circuit Serial Programming) for field updates, a 100,000 erase/write cycle Flash endurance rating, and nanoWatt modes that drop sleep current to roughly 100 nA. The integrated analog comparator eliminates an external op-amp in many sensor front-ends, and 128 bytes of EEPROM provides non-volatile parameter storage without an external serial EEPROM. Typical applications include industrial control loops, remote sensor nodes, white-goods and appliance control boards, automotive body electronics (non-safety), low-power IoT edge devices, battery chargers, and hobby/maker projects where PIC16 heritage code is being migrated from older through-hole DIP packages to surface-mount production boards. Designers appreciate the migration path because the SSOP-20 footprint preserves the same pin-out as the legacy 18-pin PIC16F628 family extended to 20 pins. When designing with this MCU, allocate the 224-byte RAM budget carefully - the 8-bit stack and PIC16's banking scheme place hard ceilings on local arrays and string processing. Decouple VDD with a 0.1 µF ceramic capacitor adjacent to the package, and keep the MCLR pin pulled to VDD through a 10 kΩ resistor unless in-circuit debug is required.

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.

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.

When designing with the PIC16LF648A-I/SO, place decoupling capacitors as close as possible to VDD/VSS pins, and ensure MCLR is properly decoupled to avoid spurious resets. The ICSP programming pins (RB6/RB7) must be accessible on the final PCB to enable firmware updates. For robust firmware, the configuration bits should be set early in development to lock oscillator, watchdog, and code-protect options.

PIC16LF648AT-I/ML

PIC16LF648AT-I/ML - 8-bit PIC MCU, 7KB Flash, 256B RAM | Microchip

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.

PIC16LF648AT-I/SO

PIC16LF648AT-I/SO - 8-Bit MCU, 7KB Flash, 20MHz, 18-SOIC | Microchip

The Microchip Technology PIC16LF648AT-I/SO is an 8-bit Flash-based CMOS microcontroller in the PIC16F family, featuring 7KB (4K x 14 words) of program Flash, 256 bytes of RAM, and 16 digital I/O pins, all housed in an 18-pin SOIC (7.50mm / 0.295in width) package. The LF prefix designates a low-voltage part rated for 2.0V to 5.5V operation, making it suitable for battery-powered designs, while the 20MHz maximum clock speed delivers ample throughput for typical embedded control loops. The internal 4MHz RC oscillator and dual comparator peripherals further reduce external BOM count. An 8-bit microcontroller (MCU) is a single-chip computer that integrates a CPU, program memory (Flash or ROM), data memory (RAM), and peripheral blocks (timers, ADC, communication interfaces) onto one silicon die. The PIC16F family uses a modified Harvard RISC architecture with separate program and data buses, enabling single-cycle instruction execution except for branch instructions. Within the broader embedded taxonomy, this device sits at the intersection of microcontroller -> 8-bit MCU -> PIC16 family -> PIC16F6xx sub-family, and is targeted at applications needing moderate complexity with low power consumption. Key features include nanoWatt XLP (eXtra Low Power) technology for deep sleep current in the microamp range, an integrated 10-bit ADC, two analog comparators, a USART module, and a Capture/Compare/PWM (CCP) module. The wide 2.0V to 5.5V supply range enables direct operation from a single Li-ion cell or two AA batteries without an additional regulator. With 256 bytes of RAM and 7KB of Flash, the PIC16LF648A is positioned between the smaller PIC16F627A and the PIC16F88 in the family hierarchy. The architecture relies on a 14-bit instruction word with a hardware stack depth of 8 levels, suitable for moderately nested interrupt and call structures. Watchdog timer, brown-out reset, and in-circuit serial programming (ICSP) support reduce external component requirements and simplify firmware updates in the field. Compared to 32-bit Cortex-M0 alternatives, the PIC16LF648AT offers lower BOM cost and ultra-low sleep current at the price of throughput and ecosystem tooling. Typical applications include battery-powered sensor nodes, simple motor and solenoid control loops, consumer appliance front panels, automotive interior LED drivers, and low-cost industrial timers. The 18-SOIC package supports hand-soldering and breadboard prototyping, making the part a popular choice in educational and hobby markets. When designing with this device, place a 100nF decoupling capacitor within 5mm of VDD and consider the ICSP clock/data pin assignments early in PCB layout to avoid rework. Configure unused I/O pins as outputs low to minimize sleep current. This page consolidates distributor pricing, drop-in alternatives in the 18-SOIC footprint, and engineering design notes that supplement the manufacturer datasheet with sourcing and selection guidance.

It operates at a maximum clock frequency of 20 MHz (200 ns instruction cycle) and supports an operating voltage range of 2.0V to 5.5V across the industrial temperature range of -40C to +85C. A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory, working RAM, peripherals, and I/O into one package. Within the broader hierarchy, an MCU belongs to the category of embedded processors, sitting below microprocessors (MPUs) and above digital signal controllers (DSCs). The PIC16F family from Microchip is built around a RISC Harvard-architecture core with 35 single-word instructions, optimized for deterministic real-time control in cost-sensitive embedded designs. Key features of the PIC16LF648AT-I/SS include 16 digital I/O pins, an internal 8 MHz oscillator (with factory calibration to ±1%), a 10-bit ADC with 8 channels, two 8-bit timers and one 16-bit timer, a USART module for serial communication, and an internal voltage reference. The LF prefix designates the low-voltage F-version that operates from 2.0V up. Technically, the PIC16LF648A core uses a 14-bit instruction word with a two-stage pipeline, achieving 5 MIPS peak throughput at 20 MHz. The Flash program memory supports in-circuit serial programming (ICSP) and in-circuit debugging via two pins, enabling field firmware updates and eliminating external programming hardware. The device is well suited to battery-powered and energy-conscious designs. Typical applications include consumer appliance control, battery chargers, small industrial sensors, remote controls, low-cost instrumentation, automotive interior accessories, and hobby/educational embedded projects. The wide voltage range and integrated peripherals simplify bill-of-materials in compact PCB designs. When designing with this MCU, allocate one I/O pin for the ICSP clock (RB6) and one for ICSP data (RB7) so that in-system firmware updates remain possible after board assembly. Place a 100 nF decoupling capacitor within 5 mm of the VDD pin and tie unused I/O to defined logic levels to minimize current consumption.

PIC16LF707-E/ML

PIC16LF707-E/ML - 14KB Flash 8-bit MCU, 1.8-5.5V, 44-VQFN | Microchip

The Microchip Technology PIC16LF707-E/ML is an 8-bit RISC microcontroller in the PIC16F707/PIC16LF707 family featuring 14KB of Flash program memory (8K x 14 words), 44 pins, and a 44-VQFN exposed-pad package rated for the -40C to +125C automotive temperature range. Operating from a wide 1.8V to 5.5V supply with an internal oscillator up to 16 MHz, the part combines Microchip's eXtreme Low Power (XLP) technology with integrated mTouch capacitive-touch peripherals for low-power human-interface designs. 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. This page synthesises verified distributor pricing (Mouser, LCSC, DigiKey), pin-compatible drop-in alternatives from the same Microchip PIC16F/LF family, and practical design notes compiled from the manufacturer datasheet to support rapid sourcing decisions.
