PIC16LF1508-I/ML - 8-bit XLP MCU, 7KB Flash, 20MHz | Microchip

The Microchip Technology PIC16LF1508-I/ML is an 8-bit RISC microcontroller from the PIC® XLP™ 16F family, featuring a PIC16 CPU core that runs up to 20MHz and is housed in a 20-pin QFN (4x4 mm) package with an exposed thermal pad. It integrates 7KB (4K x 14) of self-programmable Flash program memory, 256 bytes of SRAM data memory, and 18 general-purpose I/O pins, making it a compact mid-density solution for low-power embedded designs. An 8-bit microcontroller (MCU) is a small computer-on-a-chip that integrates a CPU, non-volatile program memory, RAM, and peripherals into a single package. The PIC16 core family uses a Harvard RISC architecture with a 14-bit instruction word optimized for deterministic execution. PIC16LF variants are the low-voltage members of the family, supporting 1.8V to 3.6V operation, while PIC16F variants extend to 5.5V. Within the broader taxonomy: 8-bit MCU -> microcontroller -> embedded processor -> semiconductor IC. The 'XLP' (eXtreme Low Power) designation indicates sub-uA sleep currents suitable for battery-powered applications. Key features include a 10-bit ADC with multiple channels, two comparators, four 8-bit timers (plus a WDT), on-chip PWM and CWG peripherals, an angular timer, and a Numerically Controlled Oscillator (NCO) for fine-frequency synthesis. The device supports in-circuit serial programming (ICSP), has power-on reset, brown-out reset, and an extended watchdog timer. Operating current is typically tens of uA/MHz active and below 1 uA in sleep, enabling multi-year coin-cell battery life. Architecturally, the PIC16LF1508 uses a 14-bit modified Harvard pipeline with 8-bit data path. The 7KB Flash is partitioned for self-programmability under software control, and the device includes code protection and a configuration word for fuse-based setup. Compared with 32-bit Cortex-M0 parts at similar cost, the PIC16LF1508 excels at deterministic interrupt latency, ultra-low sleep current, and toolchain simplicity (MPLAB X + XC8). Typical applications include IoT sensor nodes, low-power wireless transmitters, LED lighting controllers, battery-powered home automation, and portable consumer devices. The 20-QFN package enables compact PCB layouts where board area is constrained, and the 1.8V minimum VDD suits direct Li-ion or coin-cell power. The QFN exposed pad must be soldered to a copper pour for thermal dissipation and electrical ground. When designing, route the exposed pad (EP) to a solid ground plane with multiple thermal vias, place a 0.1uF VDD decoupling cap within 5mm of every VDD pin, and ensure the ICSP/PGD/PGC lines are accessible for in-circuit programming. Note that the 20-QFN (4x4) is the lowest-pin-count variant of the family; the pin-compatible 20-pin SPDIP, SSOP and SOIC options exist for breadboard or hand-solder prototypes.

It belongs to the PIC XLP (eXtreme Low Power) family, drawing as little as 20 nA in sleep mode while retaining full RAM and supporting peripheral operation from a 1.8V to 3.6V supply. An 8-bit microcontroller (MCU) is a single-chip computer that integrates a CPU, non-volatile program memory (typically Flash), volatile data memory (SRAM), and peripheral functions such as ADCs, timers, communication interfaces, and I/O ports into one package. The PIC16F family sits within the broader PIC microcontroller hierarchy (8-bit PIC -> PIC16 enhanced mid-range -> PIC XLP low-power tier -> Microchip 8-bit MCU -> Microcontroller -> semiconductor). MCUs are the lowest-level processing units in embedded electronics, used wherever sensor reading, decision making, actuator control, or user-interface logic is required. Compared with 16-bit or 32-bit MCUs, 8-bit devices trade raw performance for deterministic behavior, low power, low cost, and code simplicity, making them dominant in cost-sensitive and battery-powered designs.

The device supports both internal and external oscillator modes and includes a 4x PLL for 32 MHz operation from an 8 MHz internal source, giving designers flexibility to balance performance and BOM cost. Architecturally, the PIC16LF1508 uses a Harvard bus with separate program and data paths, an instruction-pipelined core, and a wide variety of Core Independent Peripherals (CIPs) that execute logic without waking the CPU. The XLP nanoWatt sleep modes (down to 20 nA with RTCC, watchdog, and BOR disabled) and the IDLE/DOZE current-scaling modes make it suited for energy-harvesting and battery applications. Internal voltage reference, power-on reset, brown-out reset, and a windowed watchdog timer are all integrated, simplifying the bill of materials. Typical applications include IoT sensor nodes, battery-powered remote controls, low-power wireless sensor interface boards, LED lighting controllers, small consumer appliances, hobby/STEM boards, and low-cost industrial control modules. The 18 I/O and 10-bit ADC allow it to read multiple analog sensors while driving PWM outputs or driving character displays. The wide 1.8V-3.6V operating range lets it run directly from a single Li-ion or two AA cells. When designing with the PIC16LF1508-I/SO, ensure decoupling caps of 100 nF plus 10 uF are placed close to VDD/VCAP, follow Microchip's MSSP layout guidelines for I2C/SPI noise immunity, and configure unused pins as outputs low to minimize sleep current. The SOIC-20 footprint is friendly to hand-soldering and reflow, which is useful for prototypes and small production runs.

The Microchip Technology PIC16LF1509-I/GZ is an 8-bit microcontroller from the PIC PIC XLP 16F family, integrating 14 KB (8K x 14) of Flash program memory, 512 bytes of SRAM, and 256 bytes of EEPROM in a compact 20-pin UQFN (4 x 4 mm) package. It executes instructions at up to 20 MHz and is rated for an operating voltage range of 1.8 V to 3.6 V, suiting battery-powered and ultra-low-power applications. The 'LF' prefix denotes the extended low-power eXtreme Low Power (XLP) technology variant, with active and sleep current budgets designed for energy-harvesting and always-on systems. An 8-bit microcontroller (MCU) is a single-chip computer built around an 8-bit data path, integrating CPU core, non-volatile program memory (Flash), volatile data memory (SRAM), non-volatile user storage (EEPROM), digital I/O, and on-chip peripherals. Within the broader semiconductor taxonomy, the PIC16LF1509 belongs to the hierarchy: microcontroller -> embedded MCU -> 8-bit MCU -> PIC16 family -> PIC16F/LF150x sub-family. The 'LF' suffix specifically selects low-voltage XLP silicon, optimized for sub-1 uA sleep currents that extend battery life in IoT endpoints, remote sensors, and wearables. Key features include 18 general-purpose I/O pins, a 10-bit ADC with multiple input channels, four 8-bit timers (plus 1 x 16-bit timer), Configurable Logic Cells (CLC), Complementary Waveform Generator (CWG), and Numerically Controlled Oscillator (NCO). The XLP technology provides multiple low-power sleep modes (Doze, Idle, Sleep), a watchdog timer, and on-chip debugging via MPLAB ICD. The instruction set is fully upward-compatible with previous PIC16 mid-range cores. Architecturally, the PIC16LF1509 uses a Harvard RISC core with a 14-bit instruction word, separate program and data buses, and a hardware stack. Internal peripherals are clock-gated and individually software-controllable for granular power savings. Compared to the PIC16F1509 (F-only, 2.0-5.5 V), the LF variant trades the upper voltage range for lower active/sleep power, making it preferable when the supply rail is fixed at 1.8-3.6 V (single Li-ion or 2x AA). All four variants (F/LF, I/E speed grades) share the same UQFN-20 (4 x 4 mm) footprint, enabling PCB reuse across designs with differing voltage and temperature budgets. Typical applications include battery-powered IoT sensor nodes, low-energy wireless remote controls, portable medical accessories, consumer appliances with always-on capacitive touch wake, LED lighting controllers, and small home-automation end-devices. The 10-bit ADC with internal voltage reference supports direct connection to thermistors, photodiodes, and low-bandwidth analog signals. When designing with this part, ensure that the supply rail stays within 1.8-3.6 V under all load transients, and that decoupling capacitors are placed within 2 mm of the VDD/VSS pins. If your system runs from a 5 V rail, select the PIC16F1509 (non-LF) instead; if it runs from a 1.5 V rail with a boost converter, validate that boost-converter ripple does not exceed 200 mVpp to preserve ADC accuracy. The MPLAB X IDE with XC8 compiler provides the recommended firmware toolchain.

A microcontroller (MCU) is a single-chip computer containing a CPU, non-volatile program memory, volatile data memory, and configurable peripherals. The PIC16LF family belongs to Microchip's enhanced mid-range 8-bit core architecture, sitting within the broader PIC16F product hierarchy of low-power flash microcontrollers. Its 'LF' designation indicates a wide-voltage, low-power variant designed for battery and energy-harvesting applications where every microwatt of quiescent current matters. Key features of the PIC16LF1509 include 14KB self-programmable Flash, 512 bytes SRAM, a 10-bit ADC with up to 12 channels, two 8-bit timers, one 16-bit timer, enhanced PWM, configurable logic cells (CLC), numerically controlled oscillator (NCO) and peripheral pin select (PPS). The 'LF' suffix supports operation down to 1.8V while the F-version extends to 5.5V, giving design flexibility across lithium-cell and 5V rails. Internal oscillator calibration and on-board ICD/debug support reduce BOM cost for prototypes. The architecture uses a Harvard RISC core with a fixed instruction set optimized for C and assembly code density. Active current is typically a few hundred microamps at 1 MHz, while sleep current drops to a few tens of nA - directly enabled by Microchip's eXtreme Low Power (XLP) technology. This makes it well-suited to duty-cycled sensor nodes. Typical applications include IoT sensor endpoints, battery-powered home automation, low-cost motor control, LED lighting controllers, and consumer white goods. The 10-bit ADC and PPS routing simplify mixed-signal front ends where most digital I/O are reassigned dynamically. When designing with this MCU, plan a decoupling capacitor (100 nF) adjacent to every VDD/VSS pair and keep analog AVCC traces isolated from switching nodes. For ultra-low-power sleep modes, use the PPS module to wake only the required peripherals and configure unused pins as outputs to avoid floating-input leakage.

The "LF" prefix denotes the low-voltage F-series variant optimized for low-power operation, while XLP (eXtreme Low Power) technology targets sub-µA sleep currents suitable for energy-harvesting and long-life battery products. Key differentiating features include XLP technology with typical sleep currents in the nanoamp range, an integrated 10-bit ADC with internal voltage reference, multiple Enhanced Low-Power Timer modules, and a peripheral pin select that simplifies PCB routing by remapping digital functions onto different I/O pins. The 28-pin SOIC package provides ample I/O for sensor fusion, user-interface buttons, and simple communication interfaces such as I2C, SPI, and async UART through the EUSART module. Architecturally, the PIC16LF1512 uses a Harvard RISC core with separate program and data buses, allowing simultaneous instruction fetch and operand access. The internal 16 MHz and 31 kHz oscillators can be switched under software control, and the device supports two-speed start-up for fast wake from sleep. The integrated Power-on Reset, Brown-out Reset, and Watchdog Timer with separate oscillator improve field reliability in industrial and outdoor installations. Typical applications include IoT sensor nodes, battery-powered remote metering, low-power motor and lighting controls, handheld instrumentation, and consumer appliances where the SOIC footprint eases hand-prototyping and rework. Design considerations include reserving adequate PCB copper under the exposed pad for thermal dissipation, using low-ESR decoupling on VDD, and verifying that the chosen ADC reference does not exceed the supply rail.

The trailing T indicates tape-and-reel packaging, while the -I suffix denotes the -40 °C to +85 °C industrial temperature range. An 8-bit microcontroller (MCU) is a single-chip computer built around an 8-bit data path, integrating a CPU, non-volatile program memory (Flash), volatile data memory (SRAM), and peripherals such as ADC, timers, and serial interfaces. Within the broader taxonomy, the PIC16LF1512 belongs to the PIC16F family of mid-range MCUs, which sits below the PIC18/dsPIC families and above baseline PIC10/12/16 devices in performance and peripheral count. 8-bit MCUs remain prevalent in cost-sensitive, low-power embedded designs where 32-bit compute is unnecessary. Key features include XLP nanoWatt technology for sleep currents in the sub-µA range, a 10-bit ADC with multiple input channels, support for mTouch capacitive touch sensing, and a wide operating voltage range of 1.8 V to 3.6 V that enables direct battery connection in 2-cell AA or single-cell Li-primary designs. The internal oscillator reduces BOM cost by eliminating external crystal components in many applications. The device uses Microchip's enhanced mid-range 8-bit core with a 14-bit instruction word, providing 35 instructions including hardware multiply. Its architecture uses a Harvard layout with separate program and data buses, and incorporates a configurable 16-level hardware stack, 25 I/O pins, and on-chip debugging via ICD. Typical applications include consumer appliances, IoT sensor nodes, battery-powered handheld devices, low-cost motor control, capacitive touch interfaces, and industrial sensor monitoring. The combination of low cost, XLP low power, and an integrated ADC makes it well-suited to distributed wireless sensor end nodes. When designing with this MCU, allocate adequate Flash and RAM headroom for stack depth and library overhead; the 128-byte RAM is the practical constraint for buffer-based protocols. Use Microchip's MPLAB X IDE with XC8 compiler, and verify low-power claims by following the XLP application note for sleep mode transitions.

PIC16LF1513-E/MV

PIC16LF1513-E/MV - 8-bit MCU, 7KB Flash, 28-UQFN | Microchip

The Microchip Technology PIC16LF1513-E/MV is an 8-bit PIC microcontroller from the PIC® XLP™ 16F family, featuring 7KB (4K x 14 words) of Flash program memory, 256 bytes of RAM, and a 20 MHz maximum CPU clock speed. The device is housed in a 28-pin UQFN (4x4 mm) exposed-pad package and integrates a 10-bit ADC with multiple channels for analog signal acquisition. As an 'LF' variant, it operates across a wide voltage range (typically 1.8V to 3.6V) and is designed for ultra-low-power (XLP) battery-friendly applications. A PIC16F-series 8-bit microcontroller is a Harvard-architecture RISC device that executes most instructions in one instruction cycle and integrates Flash program memory, SRAM data memory, on-chip peripherals (ADC, timers, PWM, UART, I/O), and a debug interface into a single IC. Within the broader component taxonomy it sits as: microcontroller (MCU) → 8-bit MCU → PIC16 → XLP low-power family → embedded controller → semiconductor. This category dominates cost-sensitive, low-power, and deterministic-control embedded designs such as sensor nodes, consumer white goods, IoT edge devices, and simple motor/lighting controllers. Key differentiating features of the PIC16LF1513-E/MV include nanoWatt XLP technology for sub-µA sleep currents, an integrated 10-bit ADC with up to 17 channels (varies by package), enhanced PWM modules, and configurable logic cells (CLC) for hardware-level signal routing without CPU intervention. The 28-UQFN (4x4) footprint delivers the full peripheral set in a 16 mm² PCB area — well-suited to space-constrained handheld and wearable designs where every square millimeter of board real estate counts. Technically, the device uses a 14-bit instruction word, supports in-circuit serial programming (ICSP) via two pins plus VPP, and offers multiple clock sources including a 16 MHz internal oscillator with PLL. The 'LF' silicon is process-tuned for low-voltage operation, allowing direct connection to a single-cell Li-ion or two AA cells without an additional LDO — a tangible BOM and PCB-area saving in battery-powered products. Typical applications include battery-powered IoT sensor endpoints, low-power wireless remote controls, LED lighting controllers with analog dimming, small consumer appliances, and automotive body/comfort sub-systems (the '-E' suffix denotes the extended -40°C to +125°C temperature grade). Designers often pair this MCU with sub-GHz transceivers, digital temperature/humidity sensors, and low-quiescent LDO regulators in 2-layer FR-2 or 4-layer FR-4 PCB stacks. When designing with this MCU, prioritize the XLP sleep-current specification early — quiescent draw below 1 µA in deep sleep typically requires careful decoupling, unused-pin tie-off, and disabling of all unused peripherals in firmware. The 28-UQFN exposed pad must be soldered to a properly sized copper pad for thermal dissipation and ground integrity.

Key features include 256 bytes of SRAM, 256 bytes of EEPROM, a 10-bit analog-to-digital converter (ADC) with multiple channels, enhanced PWM, capture/compare, an asynchronous 8-bit timer (Timer2) with 1:2:4 prescaler, plus serial peripherals such as I2C, SPI, and USART (including LIN support). The on-chip 32 kHz internal oscillator and 31 kHz low-power RC oscillator reduce external component count. Typical applications are battery-powered IoT sensor nodes, low-power remote controls, consumer appliances, industrial telemetry modules, and small motor-control peripherals. The combination of XLP nanoWatt technology, peripheral pin select, and a compact 28-UQFN footprint makes the part attractive for space- and power-constrained designs. When designing with this MCU, ensure the ICSP/ICD programming interface is brought out to a header for in-circuit programming, and review the Microchip PIC16(L)F1513 datasheet for the exact pin map of the UQFN-28 (4x4) variant, since the SP/SO packages have different pin assignments. Decoupling capacitors (100 nF + bulk) must be placed within 5 mm of the VDD pins.
