Frequently Asked Questions
What is the maximum clock frequency supported by the PIC16C554-20/P, and how does it affect instruction throughput?
The PIC16C554-20/P supports a maximum clock frequency of 20 MHz, which translates to 5 million instructions per second (MIPS) since the PIC architecture executes most instructions in 4 clock cycles. This speed is adequate for real-time control loops in appliance and sensor applications.
Which supply voltage range does the PIC16C554-20/P operate across, making it compatible with both 3.3 V and 5 V systems?
The PIC16C554-20/P operates across a supply voltage range of 2.5 V to 5.5 V, making it compatible with both 3.3 V and 5 V logic systems. This flexibility reduces the need for additional level-shifting circuitry in mixed-voltage designs.
How much program and data memory does the PIC16C554-20/P provide for small embedded firmware projects?
The PIC16C554-20/P provides 512 words of EPROM program memory and 80 bytes of data SRAM. While modest, these resources are sufficient for simple control tasks such as reading sensor outputs, driving LEDs, or toggling relays in cost-sensitive 8-bit applications.
