7204L12PI Description

The 7204L12PI is an asynchronous FIFO memory IC designed by Renesas Electronics Corporation. This IC is part of the 7200 series and features a 4K x 9 memory size with an access time of 12ns. It operates at a data rate of 50MHz and is powered by a supply voltage ranging from 4.5 V to 5.5 V. The maximum supply current is 120mA. This FIFO memory IC is mounted through-hole and comes in a tube package. Although the 7204L12PI is now obsolete, it was designed with retransmit capability, which allows for data recovery in case of transmission errors. It does not support FWFT (First Word Fall Through) or programmable flags, but it offers expansion in both depth and width, making it versatile for various applications.
