Product details

333 MHz DDR II SRAM for high-throughput pipelines

The CY7C1393KV18-333BZI: This is a volatile memory device in a 165-ball FBGA package (13x15 mm), surface-mount, intended for high-bandwidth applications such as network packet buffers, telecom line cards, and DSP scratchpads where zero dead cycles between read and write are essential. The DDR II interface transfers data on both clock edges, effectively doubling the throughput per pin compared to a single-data-rate SRAM at the same clock frequency.

No external level translation is needed when interfacing with a 1.8 V I/O bank.

Frequently asked questions

What are the operating temperature limits for CY7C1393KV18-333BZI?

This covers most outdoor telecom, base station, and industrial control environments without requiring extended-temperature screening.

Is CY7C1393KV18-333BZI compatible with 1.8V systems?

Yes. The supply voltage range is 1.7V to 1.9V, which directly supports 1.8V nominal core logic rails. No external level translation is needed when interfacing with 1.8V I/O.

What is the difference between CY7C1393KV18-333BZI and CY7C1393KV18-300BZI?

The only difference is the maximum clock frequency: the -333BZI variant is rated for 333 MHz, while the -300BZI variant is rated for 300 MHz. All other specifications — memory size, organization, supply voltage, package, and temperature range — are identical.
