The CY7C1380B-167AC is officially obsolete per Infineon's lifecycle record. No direct pin-compatible replacement is listed on the manufacturer's cross-reference. No stock-holding claim; availability and pricing verified per inquiry.
18 Mbit synchronous SDR SRAM — 167 MHz, 3.4 ns access
The parallel memory interface suits high-throughput cache or buffer applications in networking, telecom, and test equipment where deterministic read latency matters.
100-LQFP package — board-fit and rework considerations
Housed in a 100-lead LQFP (14x20 mm body, 0.5 mm pitch). The exposed pad on the 100-TQFP variant (supplier device package 100-TQFP) provides a thermal path to the PCB — a solid ground-plane via array under the pad keeps junction temperature in check during sustained burst reads. The 0.5 mm pitch is hand-reworkable with a hot-air station and fine-tipped iron — the gull-wing leads are visible for inspection and touch-up.
Sourcing posture for an obsolete SRAM
For new designs, a functional equivalent in a different package or a larger-density synchronous SRAM from the same family would require a board spin.
