CY7C421-20VXC Overview

You can find FIFO memory chip in package 28-BSOJ (0.300, 7.62mm Width) .In terms of packaging, it comes in Tube cases.In addition, the FIFO chip has a memory capacity of 4.5K 512 x 9 , which can be used to store applications and data.Reliable operation requires a temperature of 0°C~70°C .The FIFO memory's mounting type is Surface Mount .A supply voltage of 4.5V~5.5V is required for its operation.The CY7C series contains this memory logic.Surface Mount is memory IC's recommended mounting method.The 7C421 family contains this item.A supply voltage of 5V is capable of producing high efficiency.A total of 28 terminations are contained within FIFO means.The operation pins are 28 pins.In order for FIFO design to operate, a maximum current of 55mA is required.Set the supply voltage to 5V to ensure FIFO's maximum efficiency.There is a self-contained gadget within FIFOs .It has a OTHER FIFO memory type IC.When the frequency is set to 33.3MHz , the system can maintain good accuracy.Components normally possess 5V power supplies.It is also possible to generate RETRANSMIT by using this FIFO memory.Due to the use of 2 circuits, FIFO memory chip has an enhanced level of flexibility.
