Frequently Asked Questions
What is the minimum operating voltage for PIC16LF873A-I/SO and how does it benefit portable designs?
The PIC16LF873A-I/SO operates from as low as 2 V supply, allowing it to run directly from a single Li-ion cell or two AA batteries. This 2 V minimum threshold extends battery life significantly compared to 5 V-only microcontrollers, making it ideal for handheld and wireless sensor nodes where power budget is critical.
How many ADC channels does the PIC16LF873A-I/SO provide and what is the resolution?
The PIC16LF873A-I/SO includes a 5-channel, 10-bit ADC with integrated sample-and-hold circuitry. The 10-bit resolution delivers 1024 discrete levels, sufficient for temperature, pressure, and light sensing without requiring an external ADC chip, reducing BOM cost and PCB area.
When should an engineer choose PIC16LF873A-I/SO over PIC16F873A for a new design?
Choose PIC16LF873A-I/SO when the system supply voltage is below 4.5 V or when minimizing active and sleep-mode current is a priority. The LF variant is rated for 2 V to 5.5 V operation and draws less current in run mode at 4 MHz than the standard PIC16F873A, which requires 4 V minimum. Both share identical 4 KB flash and 128 bytes RAM, so firmware is binary-compatible.
What serial communication interfaces are available on the PIC16LF873A-I/SO?
The PIC16LF873A-I/SO integrates a USART for asynchronous RS-232 or synchronous SPI communication, plus a MSSP module supporting both SPI and I2C protocols up to 400 kHz in I2C fast mode. These 3 communication interfaces allow connection to sensors, EEPROMs, displays, and host processors without external interface ICs.
