The IDT 71V256SA12PZG is a 256 Kbit asynchronous SRAM organized as 32K x 8 bits, with a 12 ns access time that keeps the read cycle tight enough for most 3.3 V logic systems running at moderate clock rates. The parallel interface means no configuration overhead — address and data buses connect straight to the controller, and the chip select and output enable pins gate the bus without wait-state logic for a wide range of MCU and DSP memory controllers.
Rated for a 3 V to 3.6 V supply, this SRAM drops straight into a 3.3 V rail without an external regulator.
Supplied in a 28-TSSOP (0.465" wide, 11.80 mm body) that reflows as a 28-TSOP footprint.
