The Cypress CY7C1413BV18-200BZC is a 36 Mbit synchronous QDR II SRAM organized 2M x 18, clocked at 200 MHz over a parallel interface. It operates from a 1.7–1.9 V supply and is housed in a 165-LBGA (15×17 mm) surface-mount package. This memory targets high-bandwidth, low-latency buffer applications in networking switches, telecom line cards, and test equipment where read and write operations occur on separate ports without bus-turnaround dead cycles.
200 MHz clock — what it means for the bus
At 200 MHz, the QDR II architecture enables back-to-back read and write transactions on independent ports. For a 2M x 18 configuration, peak bandwidth is 200 MHz × 18 bits × 2 ports.
Obsolete — sourcing reality
Package and temperature grade
The 165-LBGA (15×17 mm) footprint is a standard ball-grid array for high-pin-count memory; verify the ball-out against your existing layout before committing a board spin. The 0–70 °C operating range is commercial grade — adequate for office or lab gear, but not for extended-temperature industrial or outdoor deployment.
