Frequently Asked Questions
How much Flash and RAM does the PIC18F4620-I/PT provide, and how does this compare to smaller PIC18 devices?
The PIC18F4620-I/PT provides 64 KB of Flash program memory and 3968 bytes of RAM, roughly double the Flash of entry-level PIC18F2520 variants, accommodating more complex firmware with USB stacks, display drivers, or multi-protocol communication libraries.
What clock frequency does the PIC18F4620-I/PT support, and is it sufficient for a real-time control loop at 1 ms intervals?
Running at up to 20 MHz, the PIC18F4620-I/PT executes approximately 5 million instructions per second, which is more than sufficient to close a 1 ms PID control loop for motor or temperature regulation while leaving cycles for communication tasks.
For a data-acquisition board with multiple analog channels, how does the PIC18F4620-I/PT's ADC support this use case?
The PIC18F4620-I/PT integrates a multi-channel ADC that can sample multiple analog sensor inputs, and with 36 I/O pins in a 44-pin TQFP package, the board can accommodate several sensor inputs alongside SPI, I2C, and UART peripherals without external analog multiplexers.
