CY7C421-20VXC Product Details
CY7C421-20VXC Overview
28-BSOJ (0.300, 7.62mm Width) is the package in which FIFO memory chip is contained.Tube case is used for packaging.There is a memory of 4.5K 512 x 9 on the FIFO chip that can be used to store applications and data.A temperature regulation of 0°C~70°C is crucial for reliable operation.This FIFO memory has a mounting type of Surface Mount .A 4.5V~5.5V supply voltage is required to power it.It is a component from the CY7C series.Surface Mount is recommended as the mounting method.In terms of its family, it is part of the 7C421 family.A supply voltage of 5V allows for high efficiency.FIFO consists of 28 terminations, which indicates that FIFO means is empty.28 pin is used for operation.In order for FIFO design to operate, a maximum current of 55mA is required.The supply voltage should be set to 5V in order to achieve FIFO's maximum efficiency.The gadget in FIFOs is self-contained.It has a type OTHER FIFO memory IC.In the presence of a 33.3MHz frequency, it can maintain good accuracy.Normaly, the component is powered by 5V power supplies.It is also possible to generate RETRANSMIT using this FIFO memory.Using 2 circuits allows for enhanced flexibility.
