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. ## Supply rail and temperature grade Rated for a 3 V to 3.6 V supply, this SRAM drops straight into a 3.3 V rail without an external regulator. The 0°C to 70°C commercial temperature range fits office equipment, telecom line cards in conditioned environments, and benchtop instrumentation — not outdoor or under-hood applications. ## Package and footprint Supplied in a 28-TSSOP (0.465\" wide, 11.80 mm body) that reflows as a 28-TSOP footprint. The surface-mount package suits automated assembly lines and keeps board area small. ## Lifecycle and sourcing The 71V256SA12PZG carries an Active lifecycle status, so there is no end-of-life risk for current production builds.","metaTitle":"71V256SA12PZG 256Kbit Asynchronous SRAM, 12 ns, 28-TSOP","metaDescription":"71V256SA12PZG 256Kbit (32K x 8) parallel asynchronous SRAM with 12 ns access time. 3V-3.6V supply, 0°C-70°C commercial temp, 28-TSOP package.
