What are the key features of PIC12LF1840-E/SN?
- 8-bit PIC12 core at up to 32 MHz with 7 KB Flash and 256 bytes EEPROM for non-volatile parameter storage
- Integrated 8-bit DAC and 10-bit ADC enabling mixed-signal sensing and output generation in a single 8-pin SOIC
- nanoWatt XLP technology with 1.8 V minimum supply and sleep currents as low as 30 nA for coin-cell designs
- Configurable Logic Cell (CLC) and Numerically Controlled Oscillator (NCO) for custom signal processing without CPU load
What is PIC12LF1840-E/SN used for?
The PIC12LF1840-E/SN is well suited for space-constrained, battery-powered sensor nodes such as smoke detectors, proximity sensors, and remote temperature loggers where the combination of an integrated DAC, ADC, and EEPROM reduces external component count. Its nanoWatt XLP technology and 1.8 V minimum supply allow multi-year coin-cell operation in wireless sensor applications that spend most of their time in deep sleep. The 8-pin SOIC footprint makes it an easy drop-in for retrofit upgrades in legacy single-chip designs previously using discrete transistor comparator circuits.

Frequently Asked Questions
What analog output capability does PIC12LF1840-E/SN provide on-chip?
It includes an 8-bit digital-to-analog converter (DAC) capable of generating a programmable voltage reference from the supply rail down to near-ground, useful for comparator threshold setting, sensor biasing, and simple waveform generation without an external DAC IC.
How much non-volatile memory does PIC12LF1840-E/SN offer and what data can be stored there?
The device provides 7 KB of Flash program memory and 256 bytes of EEPROM data memory; the EEPROM retains calibration constants, device settings, and sensor offsets through at least 100,000 write cycles and 40-year data retention at 85°C.
At what minimum supply voltage can PIC12LF1840-E/SN reliably run and what clock speed does that allow?
The PIC12LF1840-E/SN operates reliably at a minimum supply of 1.8 V while running at up to 16 MHz; at 3.3 V or higher it can reach its full 32 MHz maximum clock, giving designers flexibility to trade speed for power consumption as the battery drains.
Which applications benefit from the Configurable Logic Cell (CLC) peripheral in PIC12LF1840-E/SN?
The CLC allows combinational and sequential logic functions — such as PWM gating, interrupt steering, and signal conditioning — to run at hardware speed without CPU intervention, enabling sub-microsecond response times in motor driver interlock and power-sequencing circuits.
