Frequently Asked Questions
What is the maximum clock frequency and how does it affect throughput for PIC16F628AT-I/SS?
The PIC16F628AT-I/SS operates at up to 20 MHz, and with the PIC16 architecture executing most instructions in 1 clock cycle (at 4 clocks per instruction cycle), this yields 5 MIPS throughput. That performance level is adequate for tasks like UART communication at 115200 baud, PWM generation, and simple closed-loop control in 8-bit embedded applications.
How many I/O pins does PIC16F628AT-I/SS provide and can they be individually configured?
The device provides 16 I/O pins configurable independently as inputs or outputs via TRIS registers, with each pin supporting standard CMOS logic levels. Several pins are multiplexed with USART TX/RX, timer capture/compare, and analog comparator functions, giving designers flexibility to choose the peripheral mix that best matches their application without wasting unused pins.
When would a designer choose PIC16F628AT-I/SS over a 32-bit ARM MCU for a relay controller?
For a simple relay controller requiring 8 digital outputs, a UART interface, and firmware under 2 KB, the PIC16F628AT-I/SS offers significantly lower cost and simpler toolchain requirements than a 32-bit ARM Cortex-M device. The 8-bit device's 3.5 KB flash is more than adequate, and the SSOP-20 package costs a fraction of an ARM MCU in small-to-medium production volumes.
What is the factory lead time for PIC16F628AT-I/SS and what package does it use for SMT assembly?
PIC16F628AT-I/SS has a standard factory lead time of 6 weeks and ships in an SSOP-20 package with 20 pins. The SSOP-20 is compatible with standard automated SMT pick-and-place assembly lines and tape-and-reel delivery, making it practical for volume production in consumer electronics and industrial control applications.
