71V256SA20PZG8

Overview

The Renesas Electronics Corporation 71V256SA20PZG8 is a 3.3V CMOS Asynchronous Static Random Access Memory (SRAM) organized as 32K x 8, providing a total storage capacity of 256 kbit. It features a parallel interface with a maximum access time of 20 ns. The device operates within a supply voltage range of 3 V to 3.6 V and draws a maximum power supply current of 85 mA. Designed for surface mount applications, it is housed in a 28-pin TSOP package. The component supports commercial temperature grades ranging from 0°C to +70°C.

Feature Summary

• Fully static asynchronous circuitry requiring no clocks or refresh cycles for operation
• Low standby power consumption contributing to extended battery life in portable applications
• LVTTL-compatible inputs and outputs ensuring compatibility with standard logic families

Applications

• High-performance processor secondary cache systems
• Industrial equipment requiring reliable data storage
• Consumer electronics utilizing single 3.3V power supplies

Procurement Notes

Verify the obsolete status of this component before procurement planning. Confirm that the specific suffix PZG8 matches the required 28-pin TSOP package and commercial temperature grade. Ensure replacement strategies are established due to discontinuation. Validate RoHS compliance details through official manufacturer documentation prior to integration.

Selection Notes

Select this part when a 20 ns access time meets system timing requirements. Choose this model for designs needing a 32K x 8 organization in a compact TSOP-28 footprint. Consider alternatives if industrial temperature ranges or faster speeds are necessary. Verify pinout compatibility during board redesigns for legacy replacements.

Part Context

This component belongs to the 71V256SA series of 3.3V asynchronous SRAMs. The series offers various speed grades and packaging options including SOJ and TSOP types. The 71V256SA20PZG8 specifically denotes the 20 ns speed variant in a tape-and-reel TSOP-28 configuration. It represents a legacy product line from Renesas and its predecessor IDT.
