The 18-bit word width suits DSP coefficient tables or packet-header lookup buffers where 16-bit data plus parity or tag bits ride the same bus without packing overhead. Infineon lists the CY7C1443KV33-133AXI as Obsolete. The 100-TQFP package and 133 MHz speed grade narrow the field of drop-in alternatives. Any replacement must match the 100-pin LQFP footprint, the 3.3V supply rail, and the synchronous SDR interface at 133 MHz. ## Industrial temperature and supply margin The 3.135V–3.6V supply range provides 0.465V of margin below the nominal 3.3V rail, enough to ride through a 10% droop on a lightly regulated bus.","metaTitle":"CY7C1443KV33-133AXI SRAM 36Mbit 133 MHz Obsolete – Infineon","metaDescription":"CY7C1443KV33-133AXI 36Mbit synchronous SDR SRAM, 133 MHz clock, 6.5 ns access, industrial temp.
