PIC16LF1518-E/SS - 8-bit MCU, 28KB Flash, 20MHz, 28-SSOP | Microchip
The Microchip PIC16LF1518-E/SS is an 8-bit PIC microcontroller from the PIC® XLP™ 16F family, featuring 28KB (16K x 14 words) of Flash program memory and 1024 bytes of RAM, housed in a 28-pin SSOP package. It operates at up to 20MHz CPU clock from a 1.8V to 3.6V supply and integrates a 10-bit ADC, two CCP modules, SPI, I2C, and EUSART peripherals, with Microchip's nanoWatt XLP technology for ultra-low-power operation.
A PIC microcontroller is a compact, self-contained computer-on-a-chip built around a RISC (Reduced Instruction Set Computer) Harvard architecture core, combining CPU, non-volatile Flash memory, SRAM, and configurable peripherals on a single die. PIC MCUs sit at the lowest tier of the microcontroller taxonomy (microcontroller -> embedded processor -> semiconductor IC) and are widely used where deterministic timing, low power, and small footprint outweigh raw compute performance. The "LF" prefix in PIC16LF1518 indicates the wide-voltage, low-power XLP variant, while "F" parts (e.g. PIC16F1518) target the 2.3V-5.5V range.
Key differentiating specifications of the PIC16LF1518-E/SS include 28KB Flash with 16K x 14 instruction-word organization, 1024-byte SRAM, 256-byte EEPROM, 17 I/O pins, a 10-bit ADC with multiple channels, two capture/compare/PWM modules, an enhanced USART with auto-baud, an SPI peripheral, and a master I2C/SPI interface. The "-E" suffix denotes the -40°C to +125°C extended industrial temperature grade, and the "/SS" suffix denotes the 28-pin SSOP (Shrink Small Outline Package) form factor.
Architecturally, the PIC16LF1518 uses Microchip's enhanced mid-range 8-bit core with a 14-bit instruction word, 8-level hardware stack, and a two-cycle PLL-free oscillator option (HFINTOSC up to 16MHz, LFINTOSC for low-power). nanoWatt XLP technology delivers typical sleep currents below 1 µA, enabling battery-powered designs that wake on interrupts or WDT. The ADC is an Successive Approximation Register (SAR) type with up to 17 analog channels in this pinout.
Typical applications include battery-powered sensor nodes, low-power IoT edge devices, consumer white goods user-interface controllers, automotive body and climate-control sub-modules (with the -E grade being automotive-suitable), and industrial metering. The wide 1.8V-3.6V supply allows direct operation from a single Li-ion/LiPo cell or two AA cells.
A key design consideration is the proper configuration of the configuration-word bits (FOSC, WDTE, PWRTE, BOREN) and the choice of internal vs external oscillator: enabling the internal HFINTOSC and disabling the WDT cuts sleep current to the nanoWatt XLP range. Engineers migrating from older PIC16F1xxx parts should re-validate interrupt latency and PPS pin-mapping behaviour.
This page synthesizes distributor pricing, drop-in same-package alternatives drawn from the PIC16LF151x family and verified cross-reference data, and practical design notes not found in the standalone manufacturer datasheet, providing information gain beyond Digi-Key/Mouser product listings.
