It operates from a single 3.0V to 3.6V supply, making it a direct fit for 3.3V logic buses in embedded systems, networking gear, and industrial controllers that need a fast, byte-wide or word-wide scratchpad. The 12 ns access time means the SRAM can keep up with a 66 MHz bus without wait states, assuming the controller's output hold time is met. The parallel interface is straightforward — no clock, no burst mode — so timing closure is simpler than with synchronous SRAMs. The supply range of 3.0V to 3.6V covers the nominal 3.3V rail with margin for ripple and regulation tolerance. The write cycle time matches the read access time at 12 ns, so the bus does not need asymmetric timing. The 44-TSOP II package (0.400-inch body width, 10.16 mm) is a standard footprint shared by many asynchronous SRAMs in the 1 Mbit to 4 Mbit range. Infineon lists the CY7C1021CV33-12ZXCT as Obsolete.","metaTitle":"CY7C1021CV33-12ZXCT SRAM 1Mbit 12ns 44-TSOP II Obsolete","metaDescription":"Infineon CY7C1021CV33-12ZXCT 1Mbit (64K x 16) asynchronous SRAM, 12 ns access time, 3.0-3.6V, 44-TSOP II.
