Frequently Asked Questions
What is the maximum clock frequency supported by the PIC16C57C-04I/SO?
The PIC16C57C-04I/SO supports a maximum clock frequency of 4 MHz, making it suitable for low-speed embedded control applications that do not require high computational throughput. This clock speed allows reliable execution of simple control tasks while keeping power consumption low.
How many I/O pins does the PIC16C57C-04I/SO provide, and what package does it use?
The PIC16C57C-04I/SO offers 20 I/O pins in a 28-pin SOIC package. The SOIC footprint measures approximately 7.5 mm in width and is compatible with standard surface-mount PCB assembly processes, making it practical for compact embedded designs.
Which embedded control applications are best suited for the PIC16C57C-04I/SO with 3 KB program memory?
With 3 KB program memory and 72 bytes RAM, the PIC16C57C-04I/SO is ideal for compact firmware tasks such as appliance timers, LED controllers, keypad interfaces, and simple sensor polling. Its 8-bit PIC16 architecture handles these tasks efficiently at up to 4 MHz without external memory.
When would a designer choose the PIC16C57C-04I/SO over a higher-density PIC16 variant?
A designer would select the PIC16C57C-04I/SO when the application requires fewer than 20 I/O lines, fits within 3 KB of program storage, and benefits from the lower cost of a smaller 28-pin SOIC device. It avoids paying for unused flash or RAM capacity in cost-sensitive consumer or industrial products operating at 4 MHz.
