Frequently Asked Questions
What clock speed and instruction throughput does the PIC12F1840-I/P achieve?
The PIC12F1840-I/P operates at a maximum clock frequency of 32 MHz, delivering up to 8 MIPS of instruction throughput. Its internal oscillator covers multiple speed settings from 31 kHz to 32 MHz, letting designers trade performance for lower power consumption without any external crystal.
Which supply voltage range keeps the PIC12F1840-I/P running at full 32 MHz speed?
The device operates across a wide supply voltage range of 1.8 V to 5.5 V. Full 32 MHz performance is maintained down to 2.3 V minimum supply, making it compatible with both 3.3 V and 5 V system rails without level-shifting circuitry.
How low can the PIC12F1840-I/P sleep current drop for a long-life battery design?
In XLP deep-sleep mode the PIC12F1840-I/P achieves sleep currents as low as 20 nA at 1.8 V, enabling coin-cell-powered designs with multi-year battery life. Wake-up latency is under 1 µs from sleep, so the device can sample a sensor quickly and immediately return to sleep.
What onboard analog peripherals does the PIC12F1840-I/P integrate?
The microcontroller integrates an 8-channel 10-bit ADC, a 5-bit DAC, two analog comparators, and a fixed voltage reference. These peripherals allow direct connection to 0–5 V analog sensors and support ratiometric measurements, reducing the need for external analog front-end components in a space-constrained 8-pin DIP-8 package.
