PIC16LF18857-E/SS - 32MHz 8-bit MCU, 56KB Flash, 28-SSOP | Microchip

The Microchip Technology PIC16LF18857-E/SS is an 8-bit PIC16 XLP microcontroller delivering up to 32MHz CPU performance with 56KB Flash, 4KB SRAM, and 256 bytes EEPROM, housed in a 28-pin SSOP (5.30mm body) package. It features an integrated 10-bit ADC with computation (ADC2), Peripheral Pin Select (PPS), EUSART, two SPI/I2C modules, 11 timers, and up to 25 I/O lines for mixed-signal embedded designs. An 8-bit PIC microcontroller (MCU) is a small, low-power computer-on-a-chip built around a Harvard RISC core, executing one instruction per clock cycle. The PIC16 family sits in the middle of Microchip's 8-bit portfolio, balancing cost, peripherals, and code density; the LF sub-family extends that hierarchy into the XLP (eXtreme Low Power) tier for battery-powered applications. A 32MHz PIC16F/LF188xx MCU bridges the gap between baseline PIC10/PIC12 parts and the higher-pin-count PIC18/dsPIC families, making it a workhorse for sensor interfacing, motor control loops, and human-machine interfaces. Key features include 32MHz internal oscillator, 1.8V-3.6V wide VDD range, 256B data EEPROM, 4KB RAM, and Microchip's Peripheral Pin Select (PPS) which lets engineers remap digital peripherals to any I/O pin - greatly easing PCB routing. The 10-bit ADC2 with averaging, oversampling, and hardware accumulation simplifies sensor signal conditioning, while the integrated EUSART plus two SPI/I2C blocks support multiple communication buses simultaneously. The PIC16LF18857 is fabricated on CMOS technology with on-chip debug and In-Circuit Serial Programming (ICSP), supported by the MPLAB X IDE and XC8 compiler. With 32KB Flash for application code (the device advertises 56KB total Flash but only 32K x 14 words are user-addressable) and 4KB RAM for data buffers, it can host real-time operating systems, USB stacks via the serial interface, or firmware update bootloaders in the upper memory region. Typical applications include IoT sensor nodes, battery-powered industrial sensors, low-power motor control, LED lighting controllers, and consumer electronics interfaces. The XLP nanoWatt features (idle/doze/sleep modes) and 1.8V minimum supply suit coin-cell and energy-harvesting designs. When designing with this MCU, allocate sufficient Flash for bootloader + application partitions and budget I/O pins carefully because PPS flexibility trades against pin count - engineers should plan pin assignments in MPLAB Pin Manager before routing. The E suffix denotes the -40C to +125C extended industrial temperature grade, qualifying the part for outdoor, automotive-cockpit, and factory-floor deployments. This page synthesizes distributor pricing, verified drop-in alternatives from the PIC16LF188xx family, and practical design notes for the 28-SSOP package, augmenting the manufacturer datasheet with engineering-oriented comparison data.

It integrates a 10-bit ADC with computation (ADC2), configurable Peripheral Pin Select (PPS), two EUSART modules, and two SPI/I2C peripherals for mixed-signal and connected embedded designs. According to the Microchip product brief, this device family targets general-purpose and low-power applications where analog performance and communication flexibility are both required. What is a PIC16 8-bit microcontroller? A PIC16 is Microchip's mid-range 8-bit MCU architecture based on a 14-bit instruction set with a RISC-like Harvard core. PIC16 microcontrollers are used as the central controller in countless embedded products, from industrial sensors to consumer appliances. The XLP designation means this part supports sleep currents in the nanoamp range, deep-sleep retention, and active run currents below 100 uA/MHz, enabling years of battery life on coin-cell or lithium primary cells. Key features include 256B of EEPROM data memory, 4KB of SRAM, up to 25 channels of 10-bit ADC2, 5-bit DAC, configurable logic cells (CLC), numerically controlled oscillator (NCO), complementary waveform generator (CWG), and zero-cross detect. The Peripheral Pin Select (PPS) allows nearly every digital peripheral to be remapped to a wide range of I/O pins, simplifying PCB routing. Hardware limit timers, windowed watchdog, and cyclic redundancy check (CRC/SCAN) provide functional-safety hooks for IEC 61508 SIL-2 capable designs. The PIC16LF18857 uses a modified Harvard core with hardware multiplier and 49 instructions, including bit-oriented operations that map cleanly to C-compiled code. With 32MHz internal oscillator accuracy of +/- 1% over the industrial temperature range and 1.8V to 3.6V VDD operation, the device eliminates external crystals in most designs and integrates critical analog directly on-chip, reducing BOM cost. Typical applications include battery-powered IoT sensor nodes, industrial process transmitters, low-power wireless Mote nodes, consumer white goods, HVAC controllers, medical handheld instruments, and automotive body electronics sub-modules. The 10-bit ADC2 with hardware averaging and oversampling makes it especially useful for bridge-sensor signal conditioning. When designing with the PIC16LF18857-I/SO, reserve an RC network on MCLR for clean reset, decouple VDD with 100nF + 1uF ceramics, and consult MPLAB Code Configurator (MCC) plug-ins to generate peripheral initialization code. Programming is supported over ICSP using PICkit 4 or MPLAB Snap debuggers, and code may be developed in MPLAB X IDE with XC8 compiler.

The Microchip PIC16LF18857-I/SP is an 8-bit PIC16 microcontroller in the eXtreme Low Power (XLP) family, featuring a 32MHz internal oscillator, 56KB (32K x 14 words) of Flash program memory, 4KB RAM and 256 bytes of EEPROM, housed in a 28-pin SPDIP (Skinny Plastic DIP) through-hole package. It belongs to the PIC16(L)F1885X/7X family that combines Analog, Core Independent Peripherals (CIPs) and communication peripherals, with the LF variant supporting an extended 1.8V to 3.6V operating range optimised for battery-powered designs. A microcontroller (MCU) is a single-chip computer that integrates a CPU, non-volatile program memory, working RAM, and peripheral interfaces onto one piece of silicon. PIC microcontrollers use a modified Harvard RISC architecture that decouples the program bus from the data bus, allowing the CPU to fetch instructions from Flash while simultaneously reading or writing data RAM in the same cycle. Within the power management IC hierarchy, the PIC16LF18857 sits as a general-purpose low-power MCU family member, derived from the PIC16 8-bit core lineage and positioned between the smaller PIC16F1xxx and the higher-pin-count PIC18 and dsPIC33 lines. The device integrates a 10-bit ADC with computation (ADC2), a complementary waveform generator (CWG), numerically controlled oscillator (NCO), configurable logic cells (CLC), zero-cross detect (ZCD) and a hardware limit timer (HLT). Communication peripherals include EUSART (LIN-capable), two SPI and two I2C. The Peripheral Pin Select (PPS) feature allows most digital peripherals to be routed to virtually any I/O pin, dramatically simplifying PCB layout for the 28-SPDIP footprint. Typical applications include IoT sensor nodes, battery-powered remote controls, low-power instrumentation, lighting controls, home appliances and automotive body electronics where the 32MHz core, generous peripheral set and XLP sleep currents in the nanoamp range combine to deliver long battery life with single-MCU BOM integration. Designers should use the MPLAB X IDE and XC8 compiler; the on-board debug header (ICSP) supports the MPLAB PICkit, Snap or ICD programmers. Pay attention to the LF vs F suffix when sourcing: the F variant covers 2.3V-5.5V while the LF supports 1.8V-3.6V - substituting one for the other requires checking the minimum VDD for the application. This page synthesises distributor pricing, drop-in same-package alternatives from the same PIC16F1885X/7X family, and practical design notes not collected in any single datasheet, helping engineers and buyers make faster, better-grounded decisions for new designs and reorders.

The architecture integrates a RISC core with deterministic single-cycle instruction execution, configurable clock sources from 31 kHz LFINTOSC up to 32 MHz HFINTOSC, and a flexible peripheral pin-select (PPS) system that allows remapping of digital functions to almost any I/O pin. This simplifies PCB layout, shortens design cycles and supports migration between PIC16 family members without re-routing the board. Typical applications include IoT sensor nodes, battery-powered consumer devices, industrial control, automotive body and lighting modules, smart home edge controllers, and low-power wireless sensor hubs. Designers choose this part for cost-sensitive designs that still require robust analog integration, hardware CIPs and ultra-low-power sleep current.

It carries four 16-bit timers, four CCP/ECCP modules, an HF-LF internal oscillator with active clock tuning, a windowed watchdog timer, and a hardware CRC/SCAN for memory integrity. The 44-QFN package exposes additional I/O pins (up to 36 general-purpose I/O) versus smaller PIC16LF188x siblings, supporting parallel and simultaneous peripheral operation. Typical applications include low-power IoT sensor nodes, battery-powered home automation, consumer appliances with touch or LED-matrix HMIs, automotive body and interior modules (non-safety), and industrial sensor interfaces. The 1.8 V minimum VDD lets designers connect directly to single-cell alkaline, NiMH, or coin-cell supplies without external boost converters. Design consideration: When migrating from PIC16F18875 to PIC16LF18875, verify that your application stays within the 1.8 V to 3.6 V window. The exposed pad of the 44-QFN must be soldered to a sufficiently large copper pour for thermal dissipation, and unused pins should be configured as outputs low to minimize current draw in sleep.

The architecture uses a 14-bit instruction word modified Harvard RISC core with a two-stage pipeline, allowing most instructions to execute in one cycle. This delivers up to 16 MIPS throughput at 32 MHz. The 14-bit instruction width uniquely suits compact code density, while the 8-bit data path keeps peripherals simple and low cost. Designers benefit from the peripheral pin select (PPS) feature that remaps digital I/O functions to almost any pin. Typical applications include consumer IoT sensor nodes, battery-powered medical wearables, automotive interior controls (a non-automotive grade part), industrial low-power telemetry, and home automation hubs. The wide 1.8–3.6 V range and integrated peripherals also suit wearable fitness bands and remote control designs. A primary design trade-off is between Flash endurance (typically 10K erase/write cycles) and long-life data logging requirements; use external EEPROM for high-write scenarios. Tape-and-reel (the "/T" suffix) mandates careful MSL-3 handling to avoid moisture-induced solder defects during reflow.

Typical applications include industrial sensor transmitters, low-power IoT edge nodes, home appliance control boards, and battery-powered metering devices. The combination of XLP sleep currents and a 10-bit ADC allows unattended sensor nodes to run for years on a single cell when duty-cycled correctly. When designing with this device, ensure the ICSP pins (PGx, MCLR) are brought out to a debug header, and select a decoupling network of one 100 nF plus one 10 uF ceramic capacitor placed within a few millimetres of the VDD pins to keep the internal regulator stable across load steps. This page synthesizes distributor pricing, drop-in same-package alternatives, and practical low-power design notes not found in the manufacturer datasheet alone, giving a 360-degree view for component selection and BOM risk assessment.

PIC16LF18876T-I/PT

PIC16LF18876T-I/PT - 8-bit 32MHz 28KB Flash XLP MCU TQFP-44 | Microchip

The Microchip Technology PIC16LF18876T-I/PT is an 8-bit PIC16 microcontroller from the PIC16F188xx family with 28KB (16K x 14 words) of Flash program memory, packaged in a 44-pin TQFP (10x10 mm) and qualified for the industrial -40C to +85C temperature range. It runs at up to 32 MHz from a 1.8V to 3.6V supply, integrates 2 KB of SRAM and 256 bytes of EEPROM, and belongs to the eXtreme Low Power (XLP) family that targets battery-friendly applications with active current in the microamp range. A microcontroller (MCU) is a single-chip computer that integrates a CPU, memory and a configurable set of peripherals. The PIC16LF18876 family sits inside Microchip's PIC16 mid-range 8-bit MCU portfolio, above baseline PIC10/PIC12/PIC16F devices but below the dsPIC and PIC32 16/32-bit families. Within the power-management hierarchy the PIC16LF18876 is classified as a power-management IC-adjacent device in the sense that it features nanoWatt XLP sleep modes, peripheral module disable, and a core-independent peripheral set that lets the chip spend most of its time in deep sleep and wake on a single timer, ADC, or interrupt edge without waking the CPU. The device integrates a 10-bit ADC with Computation (ADC2), a 5-bit DAC, multiple comparators, PWM, Complementary Waveform Generator (CWG), SMT timers, Hardware Limit Timer (HLT), Windowed Watchdog Timer (WWDT), SCAN/CRC, Zero-Cross Detect (ZCD), and Peripheral Pin Select (PPS) for flexible routing of digital functions to nearly any I/O. It supports up to 36 general-purpose I/O pins in the 44-pin package, plus multiple serial interfaces (UART, SPI, I2C) for host or sensor connectivity. In the architecture, an 8-bit modified Harvard RISC engine executes most instructions in one cycle, with a 14-bit instruction word and 16-level hardware stack. The 10-bit ADC2 can automate averaging, oversampling, threshold comparisons and burst averaging, offloading signal-conditioning work from the CPU and enabling longer sleep windows. PPS allows remapping of digital peripherals to different physical pins, which simplifies PCB layout and lets the same silicon serve different board variants. Typical applications include low-power IoT sensor nodes, battery-powered HVAC and metering peripherals, automotive body and accessory subsystems (sub-block, not AEC-Q100 in the -I grade), industrial control panels with capacitive touch via mTouch, and consumer appliances requiring long battery life. The 32 MHz core is fast enough for basic communication stacks, while the XLP sleep currents below 50 nA (typical) make it a fit for energy-harvesting or coin-cell products. When designing with this part, select an external 32.768 kHz crystal for RTC-driven sleep, or use the internal 31 kHz LFINTOSC if accuracy below ~1% is acceptable. Decouple VDD with a 100 nF ceramic placed within 2 mm of each VDD pin, plus a bulk 1-10 uF near the regulator output. For EEPROM endurance beyond 100K write cycles, spread writes across multiple pages and verify after each write. This page synthesizes live distributor pricing from DigiKey, Mouser and Octopart, lists drop-in same-package variants from the PIC16LF18876 family, and adds practical design notes not found in the manufacturer datasheet.

The Microchip Technology PIC16LF18877-E/P is an 8-bit PIC microcontroller from the PIC16F18877 family, featuring 56KB (32K x 14 words) of Flash program memory, 32MHz internal CPU clock, and housed in a 40-pin PDIP through-hole package. It belongs to Microchip's eXtreme Low Power (XLP) family and operates across a wide voltage range suitable for battery-powered and energy-harvesting applications. The part ships with 256 bytes of EEPROM, hardware peripherals including a 10-bit ADC with computation (ADC2), EUSART, two SPI/I2C modules, and Peripheral Pin Select (PPS) for flexible signal routing. An 8-bit microcontroller (MCU) is a single-chip computer that integrates a CPU, program memory (Flash), data memory (RAM), and peripherals onto one silicon die. The PIC16F18877 sits in the broader hierarchy: PIC16 (mid-range 8-bit core) -> PIC microcontroller family -> 8-bit microcontroller -> microcontroller -> embedded processing IC -> semiconductor. Compared with 32-bit Cortex-M parts, 8-bit PIC MCUs trade raw throughput for ultra-low sleep current, deterministic interrupt latency, and decades of code/toolchain maturity. Key features include the CIP (Core Independent Peripheral) set: hardware CRC/SCAN, Zero-Cross Detect, Hardware Limit Timer, Complementary Waveform Generator with dead-band control, and configurable logic cells. The device delivers typical sleep currents below 50 nA with RTC running, and active currents around 1.6 mA at 4 MHz. PPS lets designers remap digital peripherals to almost any I/O pin, simplifying PCB layout. The PIC16F18877 is built on an enhanced mid-range 8-bit RISC architecture with a 14-bit instruction word, hardware multiplier, and 32 interrupt sources. It supports In-Circuit Serial Programming (ICSP) via two pins, allowing firmware updates after PCB assembly without bootloader overhead. Typical applications include IoT sensor nodes, low-power wireless-connected devices (using EUSART/SPI to a transceiver), home appliances, battery-powered instrumentation, LED lighting control, and small motor/HVAC control loops. The wide operating voltage and ultra-low sleep current suit coin-cell or energy-harvested designs. When designing, evaluate whether the 40-pin PDIP is essential for through-hole prototyping - the same die ships in 28/44-pin QFN variants for reflow production. Always include proper decoupling (100 nF + bulk) within 5 mm of VDD pins. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes that complement the manufacturer datasheet and help engineers select the right variant faster.

PIC16LF18877-I/MV

PIC16LF18877-I/MV - 32MHz 8-Bit XLP MCU 56KB Flash | Microchip

The Microchip Technology PIC16LF18877-I/MV is an 8-bit PIC® XLP™ 16F microcontroller featuring a 32 MHz CPU, 56 KB (32K x 14 words) of Flash program memory, 256 B of EEPROM data memory, and a 10-bit ADC2 peripheral, packaged in a 40-pin UQFN (MV) 5x5 mm with exposed pad. It belongs to the PIC16(L)F1885X/7X family and combines Core Independent Peripherals, the eXtreme Low Power (XLP) technology, plus flexible communication peripherals such as EUSART, SPI, and I2C for general-purpose and low-power embedded designs. An 8-bit microcontroller (MCU) is a single-chip computer that integrates a CPU, non-volatile program memory, data RAM, and peripheral interfaces in one package. The 'PIC' architecture uses a Harvard design with separate program and data buses, optimizing instruction fetch and data access in parallel. 8-bit MCUs dominate cost- and power-sensitive applications such as consumer appliances, sensor nodes, and human-interface devices where 32-bit performance is not required. The PIC16(L)F18877 sits in Microchip's mid-range XLP portfolio, positioned between baseline 8-bit parts and higher-pin-count 16-bit dsPIC devices. Key features of the PIC16LF18877 include the 32 MHz internal oscillator with 4x PLL option, 10-bit ADC2 with computation, peripheral pin select (PPS) for flexible signal routing, and Core Independent Peripherals such as the CRC/SCAN, HLT (Hardware Limit Timer), and CWG (Complementary Waveform Generator). The 'LF' prefix denotes the F (low-voltage, low-power) variant supporting 1.8 V to 3.6 V operation; the 'F' non-LF variant extends up to 5.5 V. The 256 B EEPROM and the 10-bit ADC2 with internal voltage reference are especially useful for sensor calibration data and battery monitoring. The PIC16LF18877 is qualified for industrial-grade operation (-40C to +85C for the 'I' suffix) and supports JTAG/ICSP in-circuit programming plus debug. PPS allows digital peripherals to be remapped to almost any I/O pin, simplifying PCB routing and enabling late-stage design changes. Compared with earlier PIC16F1X devices, the 18877 family adds the ADC2 with hardware accumulation and the CWG, which is useful for motor control and power-converter gating. Typical applications include low-power IoT sensor nodes, battery-powered wearables, consumer white goods, HVAC control panels, motor control signal conditioning, and industrial sensor hubs. The 32 MHz MIPS throughput and PPS flexibility allow a single MCU to serve as both sensor interface and communications gateway. Design consideration: the UQFN-40 (5x5) package has a center exposed thermal pad that MUST be soldered to a ground copper pour for mechanical reliability and thermal dissipation. Decoupling capacitors (100 nF + 1 uF) should be placed within 3 mm of each VDD pin. Programming pins (ICSPCLK/ICSPDAT) must be accessible for production flashing.

PIC16LF18877-I/P - 8-bit 32MHz 56KB Flash XLP MCU | Microchip

The Microchip Technology PIC16LF18877-I/P is an 8-bit PIC microcontroller built on the eXtreme Low Power (XLP) architecture, delivering 32 MHz CPU performance with 56 KB of Flash program memory (32K x 14 words), 4 KB of RAM, and 256 bytes of EEPROM in a 40-pin PDIP through-hole package. The 'LF' prefix denotes the wide-voltage 1.8V-3.6V operating range, ideal for battery-powered and energy-harvesting designs. An 8-bit microcontroller (MCU) is a single-chip computer that integrates a CPU, RAM, non-volatile program memory (Flash), EEPROM data memory, and a rich set of peripherals around an 8-bit data bus. PIC microcontrollers sit in the broader hierarchy of microcontrollers -> embedded processors -> semiconductor ICs, and within the 8-bit class they are recognized for deterministic instruction execution, low power consumption, and a long-lived, well-supported toolchain (MPLAB X IDE, XC8 compiler). Key features include a 10-bit ADC with Computation (ADC2), two DACs, comparators, Capture/Compare/PWM, the Configurable Logic Cell (CLC), Complementary Waveform Generator (CWG), Zero-Cross Detection (ZCD), Peripheral Pin Select (PPS), and communication peripherals including EUSART, two SPI/I2C blocks, and the CRC/SCAN hardware block for functional safety. The device is supported by the PIC16(L)F1885X/7X family feature set, which adds Hardware Limit Timer (HLT), Windowed Watchdog Timer (WWDT), and Sleep/Idle/Doze power-management modes. The architecture combines the enhanced mid-range 16-bit instruction word with the nanoWatt XLP technology for sleep currents in the nanoamp range, allowing direct battery connection for years of operation. Built-in Core Independent Peripherals (CIPs) such as CLC and CWG offload tasks from the CPU and continue running in sleep, enabling event-driven firmware that wakes only on real stimuli. Typical applications include low-power IoT sensor nodes, battery-powered home automation, industrial control, functional-safety sensor interfaces, and consumer white goods. The 40-pin PDIP package also makes this part well suited to hobbyist prototyping, educational labs, and through-hole production runs. When designing with this MCU, allocate the PPS I/O map early so that conflicting peripheral pin assignments are resolved before PCB layout. Place a 0.1 uF decoupling capacitor within 5 mm of every VDD/VSS pair, and use the WWDT and CRC/SCAN blocks to meet functional-safety requirements for IEC 61508 SIL-2 designs.
