PIC12F1840-I/SN 8-bit MCU IC 8-Bit 32MHz 7KB FLASH
The PIC12F1840-I/SN is an 8-bit Flash microcontroller from Microchip Technology's PIC12(L)F1840 family, housed in an 8-SOIC package, designed for space-constrained, cost-sensitive, and low-power embedded applications. Based on an enhanced mid-range CPU core with 49 instructions, it features 7 KB of self-read/write Flash program memory, 256 bytes of RAM, 256 bytes of Data EEPROM, and operates across a wide voltage range from 1.8V to 5.5V, supporting an extended industrial temperature range of -40°C to +85°C.
This MCU is distinguished by its integrated capacitive mTouch™ sensing module for implementing touch interfaces without external components, a Data Signal Modulator (DSM) for combining digital and analog signals, and support for multiple communication protocols including I²C, SPI, and enhanced USART. It excels in power efficiency with eXtreme Low-Power (XLP) technology, offering nanoWatt-level current consumption in Sleep mode, and includes a 10-bit ADC with up to 5 channels, a 5-bit DAC, and multiple timers, making it a highly integrated solution for intelligent sensing and control.
