Frequently Asked Questions
How does PIC16F54-I/SS operate at 2 V supply voltage?
PIC16F54-I/SS is rated to execute instructions at up to 4 MHz when powered from a 2 V supply, and scales up to 20 MHz at 5.5 V. This makes it suitable for battery-powered applications using two AA cells or small Li-ion cells that may discharge below 3 V during use.
What type of memory does PIC16F54-I/SS use and how many instructions can it store?
PIC16F54-I/SS uses 768 bytes of Flash program memory and 25 bytes of SRAM, providing storage for roughly 512 12-bit PIC instructions. This is sufficient for simple state machine firmware, sensor polling loops, and LED control sequences in cost-optimized embedded products.
How many I/O pins does PIC16F54-I/SS provide and how are they arranged?
PIC16F54-I/SS provides 12 digital I/O pins organized across Port A (4 bits) and Port B (8 bits) in the 20-pin SSOP package. Each pin can be individually configured as input or output, supporting direct connection to LEDs, switches, relay drivers, and simple sensor interfaces without external logic.
Is PIC16F54-I/SS a good fit when a project requires an ADC?
No, PIC16F54-I/SS does not include an on-chip ADC. For designs needing analog-to-digital conversion, Microchip offers the PIC16F684 or PIC16F1705, which include 8-channel 10-bit ADCs. PIC16F54 is best suited for purely digital control tasks with its 12 I/O pins and 20 MHz clock.
