16 Mbit DDR II SRAM — 200 MHz, 1.8 V core, 165-ball BGA
The Cypress CY7C1392CV18-200BZC is a 16 Mbit synchronous DDR II SRAM organized as 2M x 8, clocked at 200 MHz, and operates from a 1.7 V to 1.9 V supply. It uses a parallel memory interface and comes in a 165-ball LBGA (13x15 mm) surface-mount package. This is a volatile, high-speed memory part intended for data buffering and cache applications in networking, telecom line cards, and DSP systems where DDR II burst throughput is needed.
200 MHz clock — timing budget for high-throughput designs
The 200 MHz clock rate defines the peak read/write bandwidth. For a 2M x 8 part, that translates to a 200 MT/s data rate on each I/O pin using DDR II double-data-rate signalling.
Commercial temperature grade — indoor deployment only
Rated for 0°C to 70°C ambient. That limits this SRAM to climate-controlled environments — telecom central offices, data centre line cards, lab instrumentation, or office equipment. Not suitable for outdoor base stations, engine bays, or factory floor enclosures without active cooling that keeps the board below 70°C.
