CY7C433-20JXC

CY7C433-20JXC Description

The CY7C433-20JXC is an asynchronous FIFO memory IC designed by Infineon Technologies, featuring a memory size of 36K (4K x 9) and an access time of 20ns. This FIFO operates at a data rate of 50MHz and is suitable for applications requiring high-speed data buffering. The device is housed in a 32-pin plastic leaded chip carrier (PLCC) package and is intended for surface mount applications. It operates within a supply voltage range of 4.5 V to 5.5 V and can handle a maximum supply current of 55mA. The CY7C433-20JXC supports retransmit capability, which enhances its reliability in data transmission. However, it does not support first-word fall-through (FWFT) or programmable flags, which are features found in some other FIFO models.
