The 64K x 16 organization maps directly to 16-bit data buses found in many MCUs, DSPs, and FPGAs — no byte-lane steering logic needed. The 12 ns access time suits moderate-speed processor interfaces and glue-logic applications. Housed in a 44-TSOP II (0.400-inch body, 10.16 mm width) surface-mount package, it is a common footprint shared across several SRAM families, making board layout straightforward if a drop-in replacement is needed later. ## Obsolete — planning your BOM line Infineon lists this part as Obsolete. The 44-TSOP II footprint is widely used — many 1Mbit asynchronous SRAMs from other vendors share the same pinout and package. A cross-reference search against the 64K x 16, 12 ns, 3.3 V, 44-TSOP II profile will yield candidates, though each must be verified for timing and supply tolerance. ## Access time and bus timing margin In a system with a 66 MHz bus (15 ns period), this leaves only 3 ns of margin for address decoding, PCB trace delay, and setup time at the processor — tight but workable with careful layout. Write cycle time is also 12 ns, so the part can sustain back-to-back writes at the same speed. If your system runs a faster clock, look for a 10 ns or 8 ns variant in the same family. The industrial temperature grade also provides margin in poorly ventilated designs where internal ambient rises above 70°C.","metaTitle":"CY7C1021CV33-12ZXIT SRAM 1Mbit 12ns 44-TSOP Obsolete","metaDescription":"Infineon CY7C1021CV33-12ZXIT asynchronous SRAM, 1Mbit (64Kx16), 12ns access, 3V-3.6V, -40°C to 85°C, 44-TSOP II.
