MCHPPIC12LF1840-I/SN
Overview
The PIC12LF1840-I/SN is an 8-bit microcontroller from Microchip's Extreme Low Power (XLP) family, featuring 7KB of flash memory in a compact 8-pin SOIC package. It operates at speeds up to 32MHz and is specifically designed for battery-operated applications where minimal current draw is critical. This device integrates versatile communication peripherals including I2C, SPI, and a LIN-compatible UART despite its small pin count.
Why Choose This Part
The primary advantage is the XLP technology, which allows for sleep currents as low as 20nA and active currents of 5.0uA at 32kHz. It provides a significant amount of program memory (7KB) and data EEPROM (256 bytes) for an 8-pin device, enabling more complex firmware than standard entry-level microcontrollers. The 16-level deep hardware stack and enhanced mid-range core improve C-code efficiency and performance.
Applications
Key Specifications
Getting Started
Developers can begin by using the MPLAB X IDE and the XC8 Compiler, which are the standard tools for Microchip 8-bit devices. Hardware development is supported by the PICkit 4 or MPLAB Snap in-circuit debugger/programmers connected via the ICSP pins. For rapid prototyping, the Curiosity Development Board (DM164137) provides a compatible socket and integrated programmer.
