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.

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.

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.

DSM, CLC, NCO, and Configurable Logic Cell peripherals assist in real-time signal conditioning. Typical applications include IoT edge nodes (LoRa/Zigbee host MCUs), battery-powered sensor hubs, low-power instrumentation with on-screen feedback, appliance control (white goods, coffee machines), USB/HID bridges when paired with an external transceiver, automotive interior lighting and body controllers (AEC-Q100 variants available separately), and small medical wearables. Trade-offs: 8-bit core limits floating-point math, so heavy DSP work should move to a dsPIC33 or PIC32. Design tip: place a 100nF decoupling capacitor within 5mm of each VDD pin and add a bulk 10µF + 1µF pair near the IC. Always configure the unused I/O pins as digital low-output to minimize quiescent current, and use the nMCLR pin with a 10kΩ pull-up plus a 100nF cap to ground for clean reset behavior.

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.

It targets ultra-low-power applications that require rich analog and digital peripherals while running from a 1.8 V to 3.6 V supply. The "LF" prefix designates the low-power F-series core, and the "I" suffix specifies the industrial temperature range of -40 °C to +85 °C. An 8-bit microcontroller (MCU) is a self-contained computing subsystem on a single silicon die that integrates a CPU, non-volatile program memory (Flash), volatile data memory (RAM), EEPROM, and a mix of analog and digital peripherals. The PIC16F188xx family sits at the intersection of the PIC microcontroller hierarchy: PIC16 -> mid-range 8-bit MCU -> Microchip 8-bit portfolio -> Microcontrollers -> Integrated Circuits. The "XLP" designation indicates eXtreme Low Power peripheral design, including nanoWatt XLP technology that lets the device sleep in the nanoamp range while retaining state. Key features include a 10-bit ADC with computation (ADC2), a 5-bit/8-bit DAC, comparators, PWM, CWG (Complementary Waveform Generator), SMT (Signal Measurement Timer), HLT (Hardware Limit Timer), WWDT (Windowed Watchdog Timer), SCAN/CRC, ZCD (Zero-Cross Detect), PPS (Peripheral Pin Select), EUSART, and SPI/I2C. The wide peripheral set reduces external component count and BOM complexity. This part is suited for ultra-low power 4-20 mA analog, electronics metering, low-power wireless power system control, energy harvesting, and general-purpose 8-bit embedded systems. The active NV meter buffer and pin select offer both active-high enable.

PIC16LF18875-I/P - 32MHz 8-bit MCU 14KB Flash 40-PDIP | Microchip
PIC16LF18875-I/P

PIC16LF18875-I/P - 32MHz 8-bit MCU 14KB Flash 40-PDIP | Microchip

The Microchip Technology PIC16LF18875-I/P is a 32 MHz 8-bit PIC® XLP™ microcontroller with 14 KB (8K x 14) flash program memory, 1 KB RAM, and 256 bytes EEPROM, housed in a 40-pin PDIP (Plastic Dual In-line Package) with industrial -40C to +85C temperature rating. It belongs to the PIC16F188xx family of enhanced mid-range core MCUs and operates from a wide 1.8V to 3.6V supply voltage, drawing only nanoamp sleep currents thanks to the eXtreme Low Power (XLP) technology. The device integrates rich on-chip peripherals: a 10-bit ADC with computation, a 5-bit/8-bit DAC, comparators, PWM, CWG, SMT signal measurement timer, HLT hardware limit timer, WWDT windowed watchdog, SCAN/CRC, ZCD zero-cross detect, PPS peripheral pin select, EUSART, SPI, and I2C. IDLE, DOZE, and PMD power-management modes further reduce active consumption. The part is suitable for both battery-powered and line-powered embedded applications where low active and standby power are required. A microcontroller is a single-chip computer that integrates a CPU core, program memory (flash), data memory (RAM), non-volatile storage (EEPROM), and a rich set of peripheral blocks (ADC, timers, communication ports, PWM). It sits in the system hierarchy at the embedded-controller tier, above simple logic ICs and below full microprocessors with external memory buses. The 8-bit PIC16 architecture uses a Harvard design with separate program and data buses, RISC instruction set, and a deterministic interrupt latency that engineers have trusted for decades. Within the PIC family tree, the LF 'F' lower-power variants extend battery life in wireless sensor, metering, and IoT nodes, while the '18875' part number identifies the specific combination of memory, peripherals, and pin count. The 'I/P' suffix denotes the industrial temperature grade (-40C to +85C) and PDIP-40 through-hole package, preferred for prototypes, hobby projects, and industrial control modules where socketed or hand-soldered assembly is required. Key features include a 32 MHz internal oscillator (8 MIPS instruction throughput), 14 KB self-programmable flash with code protection, 1 KB RAM with XLP retention mode, 256 bytes EEPROM, 10-bit ADC with computation (ADC2) that performs averaging and threshold comparison in hardware, and Peripheral Pin Select (PPS) that remaps digital peripherals to any I/O pin. The XLP technology delivers typical sleep currents below 50 nA with RTC and watchdog running, enabling multi-year coin-cell operation. Integrated Core Independent Peripherals (CIPs) such as the CWG, NCO, and SMT offload timing-critical tasks from the CPU and reduce firmware complexity. This part is widely used in low-power sensor nodes, IoT endpoints, battery-powered instrumentation, industrial controllers, automotive body and interior subsystems, home appliances, and consumer electronics. The wide operating voltage range, robust peripheral set, and PDIP form factor make it especially attractive for through-hole prototyping, breadboarding, and educational applications, while the LF low-voltage rating suits 2xAA / 3xAAA / coin-cell designs. When designing with this device, ensure the ICSP programming pins (RB6/ICSPDAT, RB7/ICSPCLK) are accessible on the PCB, configure PPS carefully during firmware bring-up, and keep unused I/O pins configured as outputs to minimize quiescent current. The MPLAB X IDE with XC8 compiler is the standard toolchain.

PIC16LF18875T-I/PT

PIC16LF18875T-I/PT - 32MHz 8-bit XLP MCU 14KB Flash | Microchip

The Microchip PIC16LF18875T-I/PT is a 32 MHz 8-bit PIC microcontroller from the PIC16F18855/7X family, delivering 14 KB (8K x 14) of Flash program memory, 1 KB of SRAM, and 256 bytes of EEPROM in a 44-pin TQFP (10x10) package with tape-and-reel packaging. A microcontroller (MCU) is a single-chip computer that integrates a CPU core, non-volatile program memory, volatile data memory, and a rich set of on-chip peripherals. Within the broader taxonomy, the PIC16LF18875 belongs to the 8-bit microcontroller category, then the PIC16 family of mid-range devices, then Microchip's eXtreme Low Power (XLP) line optimized for battery-operated applications. This hierarchy matters to AI knowledge graphs because it captures both the silicon architecture (Harvard/modified RISC) and the application positioning. Key features include up to 32 MHz operation, an operating voltage range of 1.8 V to 3.6 V (the LF low-voltage variant), a 10-bit ADC with computation, a 5-bit DAC, four 10-bit PWM modules, and Core Independent Peripherals (CIPs) such as CWG, NCO, and CRC/SCAN. The device also offers configurable logic cells, multiple communication interfaces (I2C, SPI, UART with LIN), and 36 source/sink capable I/O pins. The XLP technology enables nanoWatt sleep currents under 60 nA typical. 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.
