Memory configuration and timing — what the 20 ns access means on the bench
The 7024L20PFGI is a 64Kbit dual-port asynchronous SRAM organized as 4K x 16 bits. The 20 ns access time and matching 20 ns write cycle time mean the part can complete a read or write operation within that window — critical for bus timing when two controllers or processors share the same memory space without wait states. Dual-port architecture allows simultaneous access from two independent buses, which is what makes this part useful in shared-memory designs like multiprocessor buffers or FIFO emulation. The asynchronous interface means no clock is needed — address changes trigger the access directly.
Supply voltage and temperature range — where this part lives
Packaged in a 100-TQFP (14x14 mm) with surface-mount footprint — the 0.5 mm pitch demands a controlled reflow profile and a clean solder paste stencil.
