Frequently Asked Questions
What is the minimum supply voltage for the PIC16LF1933-I/SS and at what clock speed does it operate at that voltage?
The PIC16LF1933-I/SS operates at a minimum supply voltage of 1.8 V, supporting up to 16 MHz clock frequency at that rail. This makes it well-suited for single-cell Li-ion or two-cell AA battery-powered products requiring low quiescent current.
How does the integrated LCD driver in the PIC16LF1933-I/SS simplify meter or thermostat PCB designs?
The on-chip LCD segment driver supports direct multiplexed display control, removing the need for a separate display driver IC and its associated routing. This saves at least 1 chip, reduces BOM cost, and frees up 256 bytes of RAM for display buffer and application data at up to 20 MHz.
Which low-power sensing applications match the PIC16LF1933-I/SS capability profile?
With an on-chip ADC, 4K-word flash, and 1.8 V operation, the PIC16LF1933-I/SS suits smart utility metering, environmental data loggers, and portable temperature monitoring devices. The SSOP-28 package allows compact PCB assembly in handheld instruments with tight form factors.
How does the PIC16LF1933-I/SS compare to the PIC16F1933 for designs requiring lower operating voltage?
The LF variant extends the minimum supply down to 1.8 V versus 2.3 V for the standard PIC16F1933, enabling direct operation from a depleted single Li-ion cell. Both share the same 28-pin SSOP footprint, 4K-word flash, and 256-byte RAM, making the LF variant a drop-in choice for lower-voltage designs.
