Frequently Asked Questions

What is the maximum clock frequency of the PIC16C54C-20/SO?

The PIC16C54C-20/SO operates at a maximum clock frequency of 20MHz. Using the PIC16 RISC architecture with a 4-clock instruction cycle, this translates to an effective instruction throughput of 5 MIPS (million instructions per second), providing adequate processing power for simple control and sensing applications.

What type of program memory does the PIC16C54C-20/SO use?

The PIC16C54C uses OTP (one-time programmable) EPROM-based program memory. Once programmed, the code cannot be erased or reprogrammed, making this device appropriate for mature, finalized designs in high-volume production where unit cost is more important than field reprogrammability.

What package does the PIC16C54C-20/SO use and is it RoHS compliant?

The PIC16C54C-20/SO is housed in an 18-pin SOIC (Small Outline Integrated Circuit) package. This surface-mount package is widely supported by standard PCB assembly processes. The device is listed as lead-free (Pbfree) and RoHS compliant, making it suitable for modern environmentally regulated product designs.

Does the PIC16C54C-20/SO have an ADC or UART built in?

No, the PIC16C54C-20/SO does not include an on-chip ADC, UART, or boundary scan capability. It is a basic 8-bit microcontroller with digital I/O, a timer, and a watchdog timer. For applications requiring analog inputs or serial communication, a higher-feature PIC16 or PIC18 series device with integrated peripherals would be more suitable.

What are common applications for the PIC16C54C-20/SO?

The PIC16C54C is commonly used in simple dedicated-function controllers such as appliance timers, toy controllers, keypad decoders, LED sequencers, and remote control receivers. Its low cost, small SOIC-18 package, and straightforward PIC16 architecture make it a popular choice for high-volume, cost-driven embedded products where the application logic is fixed at production time.
