18 Mbit synchronous SRAM — 100 MHz pipeline for the bus
The Infineon CY7C1381KV33-100BZXI is an 18 Mbit synchronous SRAM organized 512K x 36, clocked at 100 MHz with an 8.5 ns access time. It is a single-data-rate (SDR) parallel-interface memory intended as a high-speed companion for FPGAs, ASICs, or network processors that need a wide, deterministic data buffer. The 3.135 V to 3.6 V supply range and industrial temperature grade (-40 to 85 °C) suit it for telecom line cards, base stations, and industrial controllers that cannot tolerate the latency of DRAM refresh.
100 MHz clock, 8.5 ns access — timing closure for the memory bus
The 8.5 ns access time from clock edge to data valid is specified at 100 MHz.
165-FBGA package — board-level reality
The 165-ball FBGA (13 x 15 mm body) is a fine-pitch BGA.
Industrial temperature grade — where it runs
Rated for -40 to 85 °C ambient, this part is suitable for outdoor telecom cabinets and industrial controllers.
Lifecycle and sourcing posture
The CY7C1381KV33-100BZXI carries an Active lifecycle status from Infineon. It is sourced and quoted to order through independent distribution; availability and current pricing are confirmed at quote time. No end-of-life notice or successor part is recorded — the part remains a standard catalog item for new designs and production replenishment.
