Frequently Asked Questions
How low a supply voltage can PIC16LF1826-I/SO operate from for battery-powered designs?
The PIC16LF1826-I/SO operates down to 1.8 V, allowing it to run at 16 MHz directly from a single lithium coin cell or two AAA alkaline cells at end-of-life. At full 5.5 V supply it reaches 20 MHz. This 1.8 V floor enables designs that extend battery life well beyond what 3.3 V-minimum devices allow.
What ADC capability does PIC16LF1826-I/SO provide for analog sensor interfacing?
The microcontroller integrates a 12-channel 10-bit successive-approximation ADC with a programmable voltage reference, providing 1024-step resolution across the 12 analog inputs. This configuration supports simultaneous acquisition planning for multi-sensor nodes measuring temperature, pressure, and light on a single chip without external ADC components.
For an IoT sleep-mode design, what is the sleep current of PIC16LF1826-I/SO?
In sleep mode, the PIC16LF1826-I/SO draws less than 20 nA at 1.8 V, which is among the lowest standby currents in the PIC16 family. A 200 mAh coin cell can theoretically sustain this sleep current for over 1,000,000 hours, making it practical for decade-long sensor node deployments between battery replacements.
Which serial interfaces are available on PIC16LF1826-I/SO for connecting external peripherals?
The device provides USART for asynchronous serial communication, SPI for high-speed synchronous data exchange at up to 5 MHz, and I2C supporting 400 kHz fast mode. These 3 interfaces allow simultaneous connection to display modules, EEPROMs, and wireless transceivers from a single 18-pin package.
Is PIC16LF1826-I/SO suitable for replacing older PIC16F devices in 18-pin SOIC layouts?
Yes, PIC16LF1826-I/SO is largely pin-compatible with classic PIC16F84A and PIC16F628 in 18-pin form factor while delivering 3.5 KB flash, 16 I/O lines, and a 12-channel 10-bit ADC that older devices lacked. The XLP core's 1.8 V operation also provides a significant power advantage over the 4 V minimum of PIC16F devices.
