CY7C1543KV18-450BZI is a high-speed CMOS static RAM chip, classified as a memory device. It integrates a static RAM and four latches into a single chip, featuring a 8K-word memory capacity, and can store up to 8K words in total. The CY7C1543KV18-450BZI has a fast_read access speed of 4.5ns and an access speed of 3.3ns (a single write = 8 clock cycles, a 20 bit write = 8 clock cycles). The chip also provides an array of options including an output latch, an output-enable feature, data bus hold, a programmable wait state, plus a Y-decode dual-port feature.

The CY7C1543KV18-450BZI is extensively used in data buffering and memory decoding applications as it is well-suited for computer or peripheral memory interfaces. It is mainly applied for applications where speed and ease of programming, as well as the advantages of a lower operating voltage are important. Other examples of applications where the CY7C1543KV18-450BZI could be used include high-speed signal processing and HD internet terminal.

The working principle of the CY7C1543KV18-450BZI is based on encoding and decoding data. It uses two separate ports, one for read and one for write operations. The output latch on the chip facilitates operations by allowing fast read cycles. The write and read cycles are initiated by specific cycles on the chip’s associated address and data buses. After the desired data is written to the chip memory, it is read from the chip memory by activating the output latch. This data can then be decoded or processed by the connected system.

In summary, the CY7C1543KV18-450BZI is an 8K-word capacity CMOS Static RAM chip used for data buffering and memory decoding applications. It has a fast-read access speed of 4.5ns and an access speed of 3.3ns, plus an array of options including an output latch, an output-enable feature, data bus hold, a programmable wait state, and a Y-decode dual-port feature. Furthermore, it operates in encoding and decoding data mode to facilitate fast read and write cycles.
