PIC16LF726T-I/ML - 8-Bit XLP MCU 14KB Flash 28-QFN | Microchip

The Microchip Technology PIC16LF726T-I/ML is an 8-bit PIC® XLP™ 16F-series RISC microcontroller delivering 20 MHz CPU performance with 14 KB (8K x 14) of on-chip Flash program memory in a 28-pin QFN (6x6 mm) package with exposed thermal pad. The LF designation indicates the wide-voltage low-power family, supporting 1.8 V to 3.6 V operation for battery-backed designs, while the Tape & Reel "/T" suffix is the standard pick-and-place packaging option for high-volume assembly. What is a PIC16 XLP microcontroller? An XLP (eXtreme Low Power) PIC16 is a family of 8-bit RISC microcontrollers built on Microchip's enhanced mid-range core that integrates nanoWatt sleep modes, brown-out reset, and a flexible oscillator block into a single chip. PIC16 devices sit at the bottom of Microchip's product hierarchy: PIC16 (8-bit) -> PIC microcontroller -> microcontroller unit (MCU) -> embedded controller -> semiconductor IC. XLP variants are positioned for ultra-low-power applications such as remote controls, sensor nodes, wearables, and energy-harvesting endpoints. Key features include 14 KB self-programmable Flash, 368 bytes SRAM, 8-channel 8-bit ADC, two 8-bit timers plus one 16-bit timer, and an internal 16 MHz oscillator. The device offers ultra-low-power sleep currents in the nanoamp range (per the XLP family characteristic), brown-out reset, watchdog timer, and on-chip In-Circuit Serial Programming™ (ICSP™) for field-upgradeable firmware. The PIC16LF726T-I/ML is built on Microchip's enhanced mid-range 8-bit core with hardware multiplier support, vectored interrupts, and a 14-bit instruction word. Its Flash program memory supports self-programming, allowing bootloaders and on-the-fly firmware updates. Peripheral integration minimizes external component count: integrated ADC, comparators, PWM, and the master I²C/SPI/EUSART serial engine remove the need for external converters or transceivers in many designs. Typical applications include handheld battery-powered instruments, wireless sensor end nodes, IoT edge devices, low-cost consumer remote controls, white-goods user interfaces, and small motor-control subsystems. The 28-QFN with exposed pad offers a compact footprint ideal for space-constrained PCBAs such as wearables, hearing-aid accessories, and BLE beacons. Industrial-grade -40 °C to +85 °C operation supports outdoor and factory-floor deployments. A critical design consideration is decoupling. Place a 100 nF ceramic capacitor as close as possible to VDD and a bulk 10 µF tantalum or ceramic capacitor on the power rail; the exposed thermal pad must be soldered to a sufficient ground copper pour for thermal dissipation and electrical ground. For low-power sleep-mode designs, follow Microchip application note TB3065 (nanoWatt XLP techniques) for sleep-mode current minimization.

The 28-pin SOIC provides 25 digital I/O pins and is rated for industrial temperature range (-40C to +85C). Technically, the PIC16LF726 uses a 14-bit instruction word and Harvard architecture (separate code and data buses) so the CPU can prefetch instructions while reading data. The LF prefix indicates the wide-voltage F-version, making it pin-and-functionally compatible with the F726 while supporting deeper sleep current targets. The 'T' suffix denotes tape-and-reel packaging for high-volume assembly. Typical applications include battery-powered sensor nodes, low-power IoT endpoints, portable consumer devices, LED lighting controllers, small appliances, and industrial monitoring peripherals where XLP sleep currents and 14KB of code space are sufficient. The wide 1.8V-5.5V supply range also simplifies designs powered from single-cell Li-ion or two-AA battery stacks. When designing with this MCU, budget code space against the 14KB Flash limit and verify that the chosen idle/sleep mode plus peripheral wake sources meet your average current budget; the ADC acquisition time is also derated above 1 MHz conversion clock, so use Fosc/16 or slower at high temperatures.

Key specifications include 22 digital I/O pins, an 8-channel 8-bit ADC, 5-bit DAC hardware PWM generator, SPI and I2C (MSSP) connectivity, two 8-bit timers plus one 16-bit timer, an internal oscillator, a 2V-5.5V operating voltage range (LF low-voltage/F variant), and industrial -40C to +85C temperature grade. The LF suffix denotes the lower-voltage 2V-5.5V variant suited to battery-powered designs. Architecturally, the PIC16LF72 combines a Harvard-bus RISC engine with on-chip Flash program memory, supporting self-programmability via ICSP and offering low-power sleep modes with brown-out reset and watchdog timer for safety-critical embedded designs. Typical applications include consumer appliance control, automotive body and lighting subsystems, industrial sensor conditioning, battery-powered instrumentation, LED lighting controllers, and small-format human-machine interface (HMI) modules where 22 I/O pins and an on-chip 8-bit ADC provide enough analog and digital bandwidth. Designers should note the exposed pad (EP) of the 28-QFN must be soldered to a sufficient copper pour for thermal dissipation and ground integrity; missing this can degrade ADC noise and brown-out-reset behavior. The 28-QFN footprint is also distinct from the 28-SOIC (SO) and 28-SPDIP (SP) variants, so PCB layouts cannot be reused across package codes.

PIC16LF73-I/ML - 8-Bit 20MHz 7KB Flash MCU 28-QFN | Microchip

The Microchip Technology PIC16LF73-I/ML is an 8-bit PIC16 RISC flash microcontroller running at 20 MHz with 7KB (4K x 14) of on-chip program Flash memory, packaged in a 28-pin QFN (6x6 mm) outline with an exposed thermal pad. It belongs to the PIC16F mid-range family and offers 192 bytes of RAM, 22 digital I/O lines, and 5 channels of 8-bit A/D conversion with two additional timers for capture, compare, and PWM operation. An 8-bit microcontroller (MCU) is a single-chip computer that integrates a CPU, program memory, data memory, and peripherals onto one silicon die. The PIC16F family uses Microchip's enhanced Harvard RISC architecture with only 35 single-word instructions, achieving 200 ns instruction execution at 20 MHz. MCUs sit in the broader hierarchy of: microcontroller -> embedded processor -> integrated circuit -> semiconductor, and they form the decision-making core of almost every embedded electronic product. Key features include a wide 2.0 V to 5.5 V supply range (LF = low-voltage/F-version variant supporting full operation down to 2.0 V), nanoWatt technology for power-managed sleep modes, an ICD (In-Circuit Debugger) interface for MPLAB development tools, and an enhanced USART with 9-bit address detection. The 28-QFN (6x6) exposed-pad package provides a low thermal resistance path to PCB copper for heat extraction. Architecturally, the PIC16LF73 separates program and data buses (Harvard), allowing instruction fetch and operand access to occur in a single 200 ns cycle. The 14-bit instruction word gives more encoding headroom than the 12-bit baseline PIC, supporting literal operations and direct bit manipulation without extra cycles. Typical applications include industrial control panels, sensor signal conditioning, low-cost consumer appliances, automotive body electronics sub-modules, and battery-powered portable instruments where low-voltage operation from a single Li-ion cell or two AA cells is required. When designing with this device, note that the 28-QFN package has no mechanical leads to absorb CTE stress - the exposed pad must be soldered to a ground copper pour for both thermal dissipation and mechanical reliability. Programming voltage is generated on-chip; no external high-voltage supply is needed.

Operating from 2.0 V to 5.5 V, it integrates 22 digital I/O, a 5-channel 8-bit ADC, two 8-bit timers, one 16-bit timer, two Capture/Compare/PWM (CCP) peripherals, and a synchronous serial port configurable as either SPI or I²C. The "LF" family variant is optimized for low-voltage battery operation, drawing substantially lower current than the PIC16F73 at 3.3 V and below. An 8-bit microcontroller (MCU) is a single-chip computer that integrates a CPU, RAM, non-volatile program memory, and peripheral interfaces into one package. The PIC16F family uses a Harvard-architecture RISC core with only 35 single-word instructions, making it well suited to deterministic real-time control and cost-sensitive embedded applications. Within Microchip's portfolio, the PIC16F73 sits in the legacy mid-range family, sitting below the PIC18 and enhanced mid-range PIC16F1xxx families in capability but retaining strong availability and a mature toolchain for hobbyist, industrial, and educational designs. Key features include an industrial -40°C to +85°C operating range, an internal 8 MHz RC oscillator with PLL option for 20 MHz system clock, in-circuit serial programming (ICSP) via two pins, and ICD (In-Circuit Debugger) support. The 28-SPDIP through-hole package simplifies prototype breadboarding and rework compared to surface-mount alternatives, while the wide 2.0-5.5 V supply range supports battery-powered and unregulated supply designs. The PIC16LF73 architecture uses a single accumulator (WREG) and a 15-bit program counter, with a hardware multiplier not present - complex math must be implemented in firmware. The Flash program memory is self-programmable, supporting field firmware updates via ICSP. The 8-bit ADC provides up to 5 channels with 8-bit resolution, suitable for slow sensor sampling rather than precision measurement. Typical applications include industrial sensor interfaces, consumer white goods motor controllers, educational embedded platforms, simple PWM LED drivers, low-cost HVAC thermostats, and battery-powered measurement instruments. The SPDIP package is particularly attractive for hobbyist and through-hole assembly workflows. When designing with this device, allocate at least one ICP/ICSP pin pair and reserve sufficient Flash/RAM for your application. Stack depth in mid-range PICs is hardware-limited (8 levels); high call-depth firmware may need to be refactored to avoid overflow. The 8-bit ADC requires accurate Vref decoupling and adequate acquisition time for accurate results.

The Microchip Technology PIC16LF74-I/L is an 8-bit RISC microcontroller from the PIC16 family, featuring 7KB (4K x 14 words) of FLASH program memory, 192 bytes of RAM, and 33 digital I/O pins in a 44-pin PLCC (J-Lead, 16.59 x 16.59 mm) package. Operating at up to 20 MHz clock input (200 ns instruction cycle), this low-voltage 'LF' variant supports 2.5V/3.3V/5V operation, enabling use in battery-powered and low-power embedded designs. A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory (FLASH/ROM), working memory (RAM), and configurable peripherals (timers, communication interfaces, ADC, GPIO) into one IC. Within the semiconductor hierarchy, the PIC16LF74 sits under 8-bit MCU -> RISC microcontroller -> embedded controller -> integrated circuit. The 'LF' suffix denotes the low-voltage family, which extends battery life compared to standard PIC16F parts while retaining the same peripheral set and pinout. Key features include 35 single-word instructions, single-cycle execution except for program branches (2 cycles), brown-out detect/reset (BOR), power-on reset (POR), watchdog timer (WDT), PWM module, and on-chip connectivity peripherals: I2C, SPI, and UART/USART. The wide operating voltage range (2.0V minimum at 4 MHz) allows direct connection to 2-cell battery stacks or regulated 3.3V rails. Typical applications include industrial control front-ends, sensor interface boards, motor control PWM drivers, low-power remote sensor nodes, and home appliance user-interface controllers. The 33 I/O pins provide generous headroom for keypad scanning, LED multiplexing, and parallel bus interfacing. Designers should consult Microchip application notes for timer configuration, CCP/PWM setup, and ICD (in-circuit debug) wiring when developing firmware.

PIC16LF74-I/ML - 8-Bit PIC MCU, 7KB Flash, 33 I/O | Microchip

The Microchip Technology PIC16LF74-I/ML is an 8-bit RISC Flash microcontroller delivering 20 MHz CPU performance, 7 KB (4K x 14) of program memory and 192 bytes of RAM in a 44-pin QFN exposed-pad (ML) package. It is the low-voltage 'LF' variant of the PIC16F74 family, supporting 2.5 V / 3.3 V / 5 V operation and offering 33 digital I/O lines with capture/compare/PWM and 8-channel 8-bit ADC peripherals. The 14-bit instruction word plus 35 instruction set gives compact code density for low-cost embedded designs. A microcontroller (MCU) is a single-chip computer that integrates a CPU core, non-volatile program memory, working RAM, and a set of peripherals such as timers, communication ports and ADCs. The PIC16F family is the classic 8-bit mid-range line from Microchip, sitting between the baseline PIC10/12/16 and the high-performance PIC18/PIC24 families. The 'LF' suffix designates the low-voltage process, allowing VDD operation down to 2.0 V typical for battery-powered applications, while the 'F' indicates Flash program memory that can be reprogrammed in-circuit via ICSP. Key features include 7 KB Flash program memory, 192 bytes SRAM, hardware USART, MSSP (SPI/I2C) port, two 8-bit timers with capture/compare, one 16-bit timer/counter, 8-channel 8-bit ADC, dual analog comparators and a watchdog timer with on-chip low-power RC oscillator. The PIC16LF74 also supports in-circuit serial programming (ICSP), enabling field firmware updates via two pins. Its nanopower techniques and wide voltage range make it well suited to portable and energy-harvesting designs. Typical applications include industrial control panels, sensor signal conditioning, battery-powered instrumentation, automotive body electronics (non-safety), and consumer appliance controllers. The 33 I/O and high-resolution peripherals simplify designs that require many push-buttons, LEDs and analog inputs without an external I/O expander. Design tip: when migrating to PIC16LF74, place the ICSP VPP/VDD pair, the MCLR pull-up resistor, and the 33 I/O ESD protection close to the IC. The 44-pin QFN has an exposed thermal pad that must be soldered to the ground plane for electrical and thermal performance.

PIC16LF74-I/PTG - 8-Bit 20MHz MCU 7KB Flash 44-TQFP | Microchip

The Microchip Technology PIC16LF74-I/PTG is an 8-bit RISC microcontroller from the PIC16F family, delivering 7KB (4K x 14) of FLASH program memory, 192 bytes of RAM, and 33 digital I/O lines in a 44-pin TQFP (10x10 mm) surface-mount package. It operates at a maximum clock frequency of 20 MHz across a 2.0V-5.5V supply range, suiting it to both 3.3V and 5V rails common in industrial and consumer designs. The CMOS architecture delivers low power consumption typical of the PIC16F mid-range family. An 8-bit microcontroller (MCU) is a single-chip computer built around an 8-bit data path, integrating a CPU core, program memory (ROM/FLASH), working RAM, digital I/O, and on-chip peripherals such as timers, capture/compare modules, and communication interfaces. The 8-bit MCU category sits beneath the broader semiconductor hierarchy: MCU -> microcontroller -> embedded processor -> semiconductor IC. The PIC16F mid-range family specifically uses a 14-bit instruction word and Harvard architecture, and the PIC16LF74 belongs to this family. Key differentiating features include 7KB of in-system self-programmable FLASH (4K x 14 words), 192 bytes of data RAM, three timers, dual analog comparators, and a 10-bit ADC with up to 8 channels (per family datasheet). The 'LF' prefix denotes an extended low-voltage variant (2.0V VDDmin), distinguishing it from the standard PIC16F74 (4.0V VDDmin). The 44-pin TQFP package exposes 33 I/O lines plus oscillator, reset, and power pins, supporting a broad peripheral footprint. Technical depth: the PIC16LF74 uses an enhanced mid-range 8-bit core with 35 instructions, single-cycle execution at 20 MHz (200 ns instruction cycle), and a hardware multiplier unavailable in baseline PIC cores. The device supports In-Circuit Serial Programming (ICSP) via two pins (RB6/RB7) and In-Circuit Debugger (ICD) on the same pins, simplifying field updates and development without removing the chip. Typical applications include industrial control panels, sensor signal conditioning front-ends, low-cost motor-driver sub-controllers, automotive body and lighting controllers, and embedded data-acquisition nodes where a low-voltage, low-pin-count 8-bit MCU suffices. The 7KB FLASH supports moderate control-loop code plus a small protocol stack. Design consideration: at 20 MHz from 5V, power dissipation remains modest (tens of mW), but adequate decoupling (100 nF + 10 uF near VDD/AVDD) and a stable clock source (crystal or internal RC) are required for reliable ADC accuracy. Watchdog timer and brown-out reset (BOR) should be enabled for industrial environments.
