PIC16LF1503-I/MV - 8-bit MCU, 3.5KB Flash, 20MHz, 16-UQFN

The Microchip Technology PIC16LF1503-I/MV is a low-power, 8-bit flash microcontroller from the PIC16 family featuring 3.5KB (2K x 14 words) of self-programmable Flash program memory, 128 bytes of SRAM, and an integrated 10-bit ADC. Housed in a compact 16-pin UQFN (3x3 mm) package with exposed pad for thermal dissipation, it operates over a 1.8V to 3.6V supply range with 20MHz CPU clock. An 8-bit microcontroller (MCU) is a programmable system-on-chip that integrates a CPU, non-volatile program memory, RAM, and peripherals such as timers, communication interfaces, and ADCs onto a single silicon die. PIC microcontrollers use a modified Harvard RISC architecture where instructions and data are fetched on separate buses, enabling single-cycle instruction execution. The PIC16LF1503 belongs to the enhanced mid-range PIC16 family that adds data-memory support, deeper hardware stack, and configurable peripherals while keeping the cost and simplicity that made the PIC16 one of the most widely deployed 8-bit MCU architectures in the industry. Key features of the PIC16LF1503-I/MV include 12 I/O pins with individually selectable weak pull-ups and interrupt-on-change, four Configurable Logic Cells (CLC) for hardware glue logic, a Complementary Waveform Generator (CWG), a Numerically Controlled Oscillator (NCO), and a 10-bit ADC with up to 11 channels. The device supports In-Circuit Serial Programming (ICSP) via two pins and offers Power-on Reset (POR), Power-up Timer (PWRT), Programmable Low-Power Brown-out Reset (LPBOR), and an extended Watchdog Timer (WDT) programmable from 1 ms to 256 seconds. These features allow the MCU to operate standalone in battery-powered and field-deployed systems with no external supervisor. Architecturally, the PIC16LF1503 uses a 14-bit instruction word with a 16-level hardware stack with optional overflow/underflow reset, supporting up to 8K x 14 instruction space. Internal oscillator options up to 16MHz with a 4x PLL enable 16MHz and 20MHz operation without external crystals, simplifying BOM and reducing board area. Enhanced peripherals, including the CWG and NCO, move functions like waveform generation and precision frequency synthesis off the CPU core, lowering active-mode current and enabling deeper sleep modes for energy harvesting and IoT designs. Typical applications include consumer appliances, security alarm panels, motor control (small BLDC drivers), building automation nodes, wearables, LED lighting control, and portable medical accessories. The wide operating voltage (1.8V-3.6V) and tiny 3x3 mm UQFN footprint make it a strong fit for space- and power-constrained designs. When designing with the PIC16LF1503-I/MV, route the exposed thermal pad to a continuous ground plane and verify the supply decoupling network (typically 100 nF plus 1-10 uF bulk) is placed within a few millimeters of VDD. Use Microchip's MPLAB X IDE with XC8 compiler for code development and PICkit programmer for in-circuit debug.

The device supports 32 interrupt sources, an internal 16 MHz high-speed oscillator calibrated to ±1%, and a power-saving Sleep mode with < 50 nA typical current for battery-backed applications. The PIC16LF1503 uses CMOS process technology and the PIC16 enhanced mid-range core that executes most instructions in one instruction cycle, giving roughly 200 ns instruction time at 20 MHz. Its internal oscillator eliminates the need for an external crystal on cost-sensitive designs, while the CLC and PWM/COG peripherals allow hardware-configurable glue logic without external parts. Typical applications include battery-powered sensor nodes, LED lighting controllers, small appliance control (coffee makers, fans), consumer remote controls, and low-cost IoT edge devices. The combination of wide voltage range, low sleep current, and integrated analog peripherals makes it well-suited for designs previously dominated by discrete logic or larger 32-bit controllers. When designing with this MCU, ensure VDD decoupling is within 1 cm of the pin with at least a 0.1 uF ceramic capacitor, and leave the ICSPCLK/ICSPDAT pins accessible for in-circuit serial programming. Migrating from the LF (1.8-3.6 V) to the non-LF F variant (PIC16F1503-I/P) requires re-checking analog peripheral specifications at the new voltage rail.

The NanoWatt XLP technology extends sleep current into the nanoampere range, making the part suitable for battery-powered sensor endpoints. The enhanced mid-range core delivers 49 instructions and 16-level deep hardware stack, with self read/write Flash capability enabling bootloader-free firmware updates. The internal 16MHz oscillator eliminates the need for an external crystal in space-constrained designs. The PIC16LF1507 uses a 14-bit instruction word with single-cycle execution for most instructions, achieving effective throughput close to 5 MIPS at 20MHz FOSC. Typical applications include consumer white goods user interfaces, low-cost IoT sensor nodes, LED lighting controllers, battery chargers, small home appliances, and automotive interior accessories (PIC16LF1507-E grade = -40°C to +125°C). The 20-SSOP footprint is drop-in compatible with the SOIC-20 footprint on many reference designs, easing PCB rework. When designing with this part, allocate a 0.1µF decoupling capacitor within 3mm of VDD, and route the MCLR pull-up (when enabled) directly to VDD. Configure unused I/O as outputs low to minimize quiescent current. The ADC benefits from a 100nF + 10µF analog supply RC network if a separate analog AVSS is used.

PIC16LF1507-I/SO - 8-bit MCU, 3.5KB Flash, 18 I/O, 10-bit ADC

The Microchip Technology PIC16LF1507-I/SO is an 8-bit PIC microcontroller with 3.5KB Flash program memory, 128B RAM, and 18 I/O pins, housed in a 20-pin SOIC package. It operates at up to 20 MHz CPU clock from a 1.8V to 3.6V supply and integrates a 12-channel 10-bit ADC, two Configurable Logic Cells (CLC), a Complementary Waveform Generator (CWG), and a Numerically Controlled Oscillator (NCO). A PIC (Peripheral Interface Controller) microcontroller is a compact single-chip computer built around a RISC core, integrating CPU, non-volatile Flash memory, RAM, and configurable peripherals such as ADC, timers, and communication interfaces. Within Microchip's portfolio, PIC MCUs occupy the 8-bit segment sitting between simple 8-bit MCUs and the higher-performance 16-bit dsPIC/PIC24 families; the PIC16F150x/PIC16LF150x series is the enhanced mid-range family offering CLC, NCO, and CWG peripherals for digital logic synthesis without external components. The 'LF' prefix designates the wide-voltage, low-power variant, while 'F' denotes Flash program memory.

The device runs up to 20 MHz instruction rate and operates from a 1.8 V to 3.6 V supply, making it a member of the low-voltage 'LF' family aimed at battery-powered applications. A microcontroller (MCU) is a single-chip computer that integrates a CPU, non-volatile program memory (Flash), volatile data memory (RAM), and a configurable set of peripherals. Within the broader taxonomy, an 8-bit MCU such as this belongs to the PIC16F family of microcontrollers, which sits inside Microchip's PIC family of RISC microcontrollers, which in turn falls under the broader category of microcontrollers and embedded processing. The 'LF' prefix indicates a low-voltage variant optimised for low power consumption, while the 'F' in PIC16F1507 indicates Flash program memory. Understanding this hierarchy is essential when comparing this part to other 8-bit MCUs. Key features include a 10-bit ADC with 12 channels and a voltage reference, an internal 16 MHz oscillator (with optional PLL support for 32 MHz internal operation), 25 mA source/sink capable I/O, and four 10-bit PWM channels plus a Complementary Waveform Generator (CWG). The device integrates a Numerically Controlled Oscillator (NCO), two Configurable Logic Cells (CLC), and an integrated temperature indicator module for on-chip thermal monitoring. Self-read/write capability on the Flash memory enables data EEPROM emulation, reducing BOM cost in designs that require non-volatile storage. The architecture follows a 14-bit instruction word with a 16-level hardware stack, providing deterministic interrupt latency and predictable response times suited for hard-real-time control loops. The PIC16LF1507T-I/SO operates across the industrial -40 C to +85 C temperature range ('I' suffix) and is supplied in tape-and-reel packaging ('T' suffix), making it compatible with high-volume SMT assembly lines. Compared to the older PIC16F baseline, the enhanced mid-range core adds 49 instructions, deeper nesting, and richer peripheral set. Typical applications include consumer electronics (small appliances, toys, remote controls), industrial sensor nodes, LED lighting controllers with CWG-based constant-current regulation, battery-powered IoT endpoints that benefit from the LF voltage range, low-cost motor and fan controllers using the CLC/NCO blocks, and general-purpose logic replacement. The 20-SOIC footprint is hand-solderable and breadboard-friendly via adapters, simplifying prototyping. A key design consideration is the choice of internal vs external oscillator: using the factory-calibrated internal 16 MHz HFINTOSC eliminates two external crystal pins and reduces BOM cost, but trades off absolute frequency accuracy. For designs needing precise UART baud rates, an external 20 MHz crystal or the PLL-derived 32 MHz internal clock is recommended. The 20-SOIC package provides ample copper area for thermal dissipation at the device's low operating currents.

PIC16LF1508-E/P - 7KB Flash 8-bit MCU | Microchip XLP 20-DIP

The Microchip Technology PIC16LF1508-E/P is a low-power 8-bit PIC microcontroller featuring 7KB Flash program memory and a 20 MHz internal oscillator, housed in a 20-pin PDIP (DIP) through-hole package. The LF variant operates from 1.8V to 3.6V and is part of the eXtreme Low Power (XLP) family, making it suitable for battery-powered applications. A PIC16 microcontroller is a Harvard-architecture 8-bit RISC MCU built around a small, deterministic instruction set (typically 35-49 single-word instructions). The PIC16LF1508 sits within the mid-range PIC16 family and adds peripheral-rich features such as Configurable Logic Cells (CLC), Numerically Controlled Oscillator (NCO), Complementary Waveform Generator (CWG), and 10-bit ADC with Computation. Within the broader taxonomy, it belongs to microcontroller -> 8-bit MCU -> embedded controller -> semiconductor IC category. Key differentiating specifications include 7KB (4K x 14 words) self-programmable Flash, 256 bytes RAM, 128 bytes EEPROM, 18 I/O pins, an internal 20 MHz oscillator, and an ADC with Computation (ADC^2) that performs hardware averaging and threshold comparison autonomously. The on-chip CLC, NCO, and CWG peripherals allow custom logic, frequency synthesis, and complementary PWM generation without external circuitry. The architecture pairs a RISC CPU optimized for C compilers with a 14-bit instruction word. According to the Microchip datasheet DS40001609F, the LF-grade silicon runs down to 1.8V with a typical active current of only 30 uA/MHz and sleep currents under 50 nA with full RAM retention, enabled by nanoWatt XLP technology. The device also supports on-chip debug via the ICD header. Typical applications include low-power sensor nodes, battery-operated handheld instruments, LED lighting controllers, smoke and CO detector signal chains, and consumer appliances that require capacitive-touch or mTouch sensing on a tight power budget. The 20-pin PDIP package enables through-hole prototyping on development boards and breadboards. When designing with this part, place a 0.1uF decoupling capacitor within 5 mm of the VDD pin and a bulk capacitor (>1uF) on the same rail to handle switching transients. Verify the LF voltage range carefully: PIC16F1508 runs up to 5.5V while PIC16LF1508 is capped at 3.6V, and over-voltage on the LF grade can permanently damage the silicon.

PIC16LF1508-E/SO - 7KB Flash 8-bit MCU 20MHz XLP SOIC-20 | Microchip
PIC16LF1508-E/SO

PIC16LF1508-E/SO - 7KB Flash 8-bit MCU 20MHz XLP SOIC-20 | Microchip

The Microchip Technology PIC16LF1508-E/SO is an 8-bit PIC® XLP™ flash microcontroller featuring 7KB (4K x 14) of self-programmable program memory, 256 bytes of RAM, and a 20MHz internal oscillator in a 20-pin SOIC package. The 'LF' variant operates from 1.8V to 3.6V with Microchip's eXtreme Low Power (XLP) technology, while the 5V-compatible PIC16F1508 runs from 2.3V to 5.5V. The device integrates a 10-bit ADC with up to 18 channels, configurable logic cells (CLC), Complementary Waveform Generator (CWG), Numerically Controlled Oscillator (NCO), and multiple PWM/SCCP capture-and-compare peripherals, delivering significant analog and digital integration in a small SOIC-20 footprint. An 8-bit microcontroller (MCU) is a small, self-contained computer-on-a-chip that combines a CPU, memory (Flash/ROM for program code, RAM for data, EEPROM for non-volatile storage), and programmable peripherals on a single silicon die. The 8-bit PIC® architecture belongs to the wider category of microcontrollers -> embedded processors -> semiconductors, and uses a RISC-based Harvard architecture that executes one instruction per clock cycle (200ns at 20MHz). The 'LF' suffix denotes a low-voltage process optimized for battery-powered designs where quiescent current, sleep current (down to 20 nA typical in XLP sleep), and active run current (typically <1 mA/MHz) drive the part selection. Key features include 18 configurable I/O pins with interrupt-on-change, an on-chip 32kHz LFINTOSC plus 16MHz HFINTOSC with PLL support, an internal voltage reference for ADC, and a built-in temperature indicator. The device supports in-circuit serial programming (ICSP) via two pins, eliminating the need for an external programmer in production. Brown-out Reset (BOR), Power-on Reset (POR), and a Windowed Watchdog Timer (WWDT) provide robust fault recovery for unattended IoT nodes. Technical depth comes from the integration of CLC and NCO blocks: the CLC allows combinational and sequential logic to be implemented in hardware using internal signal routing, replacing small glue-logic ICs; the NCO generates high-resolution frequencies (up to 20-bit step) for LED dimming, IR carrier synthesis, or low-jitter clock generation without consuming CPU cycles. The 10-bit ADC supports acquisition across multiple dedicated channels including an internal Fixed Voltage Reference (FVR). Typical applications include battery-powered sensor nodes, LED lighting controls (the CWG module supports half-bridge/full-bridge topologies), consumer appliances with capacitive-touch user interfaces, and low-cost IoT endpoints. The wide 1.8V-3.6V range and ultra-low sleep current also suit energy-harvesting designs where coin-cell batteries must last the full product lifetime. The extended ('-E') temperature grade spans -40°C to +125°C, qualifying the part for industrial and certain automotive interior environments. When designing with this MCU, reserve 2 of the 20 pins for ICSP (PGC/PGD) so in-system programming is possible without removing the device from the board. Decouple VDD with a 100nF ceramic capacitor as close to the pin as practical, and configure the unused I/O pins as outputs low to minimize current draw. According to the manufacturer datasheet, the LF variant should not be powered above 3.6V — use the PIC16F1508 family for 5V-only buses.

PIC16LF1508-I/GZ - 7KB Flash XLP 8-bit MCU 20MHz 20-UQFN
PIC16LF1508-I/GZ

PIC16LF1508-I/GZ - 7KB Flash XLP 8-bit MCU 20MHz 20-UQFN

The Microchip Technology PIC16LF1508-I/GZ is an 8-bit PIC microcontroller in the PIC® XLP™ 16F family, featuring 7KB (4K x 14) of Flash program memory, 256 bytes of SRAM, and a 20MHz internal oscillator, all housed in a 20-pin UQFN exposed-pad 4x4mm package. Operating from 1.8V to 3.6V, the LF variant targets ultra-low-power applications where the standard PIC16F1508 (2.3V-5.5V) cannot meet quiescent-current budgets. A microcontroller (MCU) is a single-chip computer integrating a CPU core, program memory, data memory, and configurable peripherals. The PIC16LF1508 belongs to the enhanced mid-range PIC16 family, which uses a 14-bit instruction word and Harvard architecture, sitting in Microchip's hierarchy above 8-bit baseline PIC10/12/16 and below the 16-bit dsPIC and PIC24 families. Within Microchip's portfolio, the "LF" prefix denotes the low-voltage / low-power XLP (eXtreme Low Power) line, while the "F" prefix (PIC16F1508) covers the wider 2.3V-5.5V range. Key features of the PIC16LF1508 include a 10-bit ADC with auto-acquisition and Sleep-mode conversion capability, two rail-to-rail comparators with power-mode control, a 5-bit DAC with internal routing to the comparators and ADC, and configurable logic cells. Self-programmability under software control and Power-on Reset (POR) are standard. The device supports In-Circuit Serial Programming™ (ICSP™) and is compatible with the MPLAB X IDE and XC8 compiler toolchain. Technically, the LF variant uses Microchip's proprietary XLP technology to achieve nanoWatt sleep currents, making it suitable for battery-powered sensors that spend most of their time in Sleep mode. The 20 MHz maximum clock yields 200 ns instruction execution. The 20-UQFN (4x4) package provides a compact footprint and an exposed thermal pad for improved heat dissipation in high-I/O-count configurations. Typical applications include low-power IoT sensor nodes, battery-operated consumer devices, LED lighting controllers, and portable instrumentation. The combination of the 10-bit ADC, 5-bit DAC, and dual comparators suits closed-loop analog signal conditioning and simple mixed-signal front ends. When designing with this device, note the 1.8V minimum VDD constraint versus the standard PIC16F1508's 2.3V floor; brown-out detection must be set accordingly, and peripherals such as comparators and the ADC have reduced dynamic range below 3V. Decoupling with 100 nF and bulk capacitance close to VDD is recommended.
