PIC16F18854-E/MV - 32MHz 8-Bit XLP MCU, 7KB Flash | Microchip

The Microchip Technology PIC16F18854-E/MV is an 8-bit PIC16 microcontroller based on the enhanced mid-range core, running up to 32 MHz, with 7 KB (4K x 14 words) of Flash program memory, 512 bytes of SRAM, and 256 bytes of EEPROM, housed in a 28-pin UQFN (4x4 mm) package with exposed thermal pad. An 8-bit microcontroller (MCU) is a single-chip computer that integrates a CPU, program memory, data RAM, non-volatile EEPROM, and a mix of peripherals onto one silicon die. The PIC16F family sits in Microchip's mid-range tier - more capable than the baseline PIC10/12/16 families yet simpler than the dsPIC or PIC32 lines - making it the workhorse for general-purpose embedded control. Within that hierarchy, the 'F' suffix denotes Flash program memory, '1885X/7X' identifies the family generation that adds Core Independent Peripherals (CIPs) and eXtreme Low Power (XLP) technology. Key features of the PIC16F18854-E/MV include a 10-bit ADC with up to 24 channels, five 8-bit timers plus one 16-bit timer, two CCP modules, four 10-bit PWMs with complementary outputs, two UART/USART, two SPI, two I2C (MSSP), a Hardware Limit Timer (HLT), a Windowed Watchdog Timer (WWDT), CRC/SCAN memory safety, and a Functional Safety (FuSa) classification. XLP technology delivers a typical sleep current below 50 nA, suiting battery-powered designs. The 28-UQFN package integrates 25 I/O pins with peripheral pin select flexibility. Typical applications include low-power IoT sensor nodes, automotive body and lighting controls, consumer appliances with capacitive touch, industrial HMI and motor control loops, and any battery-powered product where deterministic 8-bit processing, hardware CIPs, and ultra-low sleep current must coexist in a compact 4x4 mm footprint. When designing with this device, take advantage of the CIPs to offload tasks like signal conditioning, waveform generation, and timing from the CPU - this lets the core stay in sleep longer. Plan decoupling per the family data sheet and follow Microchip's MQTT/Touch/Class B Safety application notes for production-ready firmware. This page combines distributor pricing, drop-in alternatives, and applied design notes not bundled in the manufacturer data sheet, giving engineers a single reference for component selection and BOM risk review.

The PIC16F18855's 8-bit RISC Harvard architecture executes most instructions in one cycle, balancing deterministic behavior with low power consumption. The 16F family sits between PIC10/12/16 baseline parts and PIC18/dsPIC enhanced parts, making it ideal for cost-sensitive yet feature-rich embedded products. Key features include an integrated 12-bit ADC with Computation (ADC²), Digital Signal Modulator (DSM), 5-/8-bit DAC, two 10-bit PWMs, configurable logic cells (CLC), Complementary Waveform Generator (CWG), Numerically Controlled Oscillator (NCO), CRC/SCAN, Hardware Limit Timer (HLT), and Zero-Cross Detect (ZCD). The device supports up to 25 I/O pins and operates across 2.5V/3.3V/5V rails. The MV suffix indicates the 28-pin UQFN (4x4) industrial-temperature package (-40°C to +85°C). On the architecture side, the device uses a 32 MHz internal oscillator with 4x PLL options, programmable peripherals through Peripheral Pin Select (PPS), and eXtreme Low-Power sleep modes drawing sub-µA currents. The Functional Safety (FuSa) features and CRC/SCAN hardware diagnostics target IEC 60730 Class B safety integrity requirements for home appliances, white goods, and industrial sensor nodes. Typical applications include consumer appliance controls, battery-powered IoT sensor nodes, LED lighting controllers, e-metering subsystems, low-cost motor control loops, and human-machine interface (HMI) panels. The combination of CIPs and 14KB Flash allows sensor conditioning, motor commutation, and serial connectivity on a single chip. When designing with this part, leverage the Peripheral Pin Select (PPS) routing to map UART/I2C/SPI functions to any digital I/O pin, which dramatically simplifies PCB layout. For low-power designs, use the eXtreme Low-Power Sleep with retention modes (sub-µA) and wake on interrupt to extend battery life in sensor-edge applications.
