18 Mbit synchronous SRAM for high-throughput buffer designs
The Cypress CY7C1372KV33-200AXC is a 18 Mbit synchronous SRAM organized as 1M×18, built on the NoBL™ architecture that eliminates dead cycles between reads and writes on the same bus. It clocks at 200 MHz with a 3 ns access time, running from a 3.135 V to 3.6 V supply. The parallel interface and 100-LQFP package (14×20 mm body) target networking buffers, DSP scratchpads, and telecom line-card applications where back-to-back throughput matters. The commercial temperature range (0°C to 70°C) suits indoor equipment in controlled environments.
3 ns access time — what it means for the bus
A 3 ns access time at 200 MHz means the SRAM can deliver data within one clock cycle of the address being latched, assuming the pipeline depth is accounted for. In practice, this gives the controller a tight timing budget for setup and hold on the data bus — critical when the part is used in a high-speed cache or FIFO buffer where every nanosecond of margin affects system stability.
NoBL architecture — no dead cycles
The NoBL™ architecture switches between read and write operations on consecutive clock edges without idle cycles. This can increase throughput compared to conventional synchronous SRAM that inserts a turnaround cycle.
