36 Mbit synchronous SRAM for high-throughput data paths
This SRAM targets networking, telecom, and high-end computing applications where a wide datapath and deterministic read latency are required. The 36-bit word width maps directly to a 32-bit data bus plus parity or ECC overhead without external muxing.
250 MHz clock and 2.6 ns access — timing budget considerations
Rated for a 250 MHz clock frequency, the CY7C1444KV33-250AXC delivers a peak data rate of 9 Gbit/s on a 36-bit bus. The 2.6 ns access time from clock edge defines the read-to-data-valid window; at 250 MHz the cycle period is 4 ns, leaving 1.4 ns of setup/hold margin for the receiving logic. This margin shrinks with board trace delay and clock skew, so signal-integrity simulation on the address/control lines is recommended before layout sign-off. The synchronous interface uses a single clock input; all address, data, and control signals are registered on the rising edge. No burst counter or DLL is required, simplifying the clock-tree topology compared to DDR variants.
Package and footprint — 100-TQFP (14x20 mm)
The 100-TQFP package with a 14x20 mm body and 0.5 mm pitch is a common footprint shared across the CY7C1444KV33 family. For a 250 MHz part, place a 0.1 µF decoupling capacitor within 2 mm of each VDD/VDDQ pin pair and use a solid ground plane on layer 2.
