It uses a parallel interface and delivers a 10 ns access time, making it suitable for cache buffers, data logging, or scratchpad memory in embedded systems that need fast, volatile storage without a clock. Packaged in a 44-pin SOJ (Small Outline J-lead) with a 0.400-inch body width, it is a surface-mount device intended for reflow soldering. The Tape & Reel variant (suffix CT) is suited for automated pick-and-place assembly. ## 10 ns access time — timing budget for the bus In a system with a 100 MHz bus clock (10 ns period), this SRAM leaves essentially zero margin for address decoding, trace delay, and setup time at the controller. It pairs best with controllers that have programmable wait states or a slower bus clock — say 50 MHz or below — where the 10 ns access fits comfortably within one cycle. For designs that burst-read or burst-write, the asynchronous nature means no clock-domain crossing issues, but also no pipelining — each access takes the full cycle.","metaTitle":"CY7C1021BNV33L-10VXCT SRAM, 1Mbit, 10 ns, Obsolete","metaDescription":"Infineon CY7C1021BNV33L-10VXCT asynchronous SRAM, 1Mbit (64K x 16), 10 ns access time, 3V-3.6V, 44-SOJ.
