71V256SA12PZG

Overview

The IDT71V256SA12PZG is a 256 Kbit (32K x 8) asynchronous static random-access memory (SRAM) manufactured by Renesas Electronics. It operates within a supply voltage range of 3.0 V to 3.6 V, with a maximum power consumption of 90 mA. The device features a parallel interface and offers an access time of 12 ns. Designed for surface-mount applications, it is housed in a TSOP-28 package. The component supports Single Data Rate (SDR) storage and functions reliably within an operating temperature range of 0°C to +70°C.

Feature Summary

• Asynchronous operation with parallel interface
• Single data rate (SDR) architecture
• Surface-mount TSOP-28 packaging

Applications

• General-purpose volatile memory storage
• Embedded system data buffering
• Industrial control unit temporary storage

Procurement Notes

This component is officially listed as End-of-Life (EOL) by the manufacturer. Availability is restricted, and distributors may not stock this specific part number in all regions. Verification of current lifecycle status and sourcing channels is required before procurement planning. Ensure compatibility with existing designs given the discontinuation status.

Selection Notes

Select this part for applications requiring low-speed asynchronous SRAM with a 12 ns access time. It is suitable for systems operating at standard 3.3 V logic levels. Consider the TSOP-28 form factor for board space constraints. Verify that the commercial temperature range meets environmental requirements.

Part Context

The 71V256SA series represents a family of high-performance asynchronous SRAMs originally developed by Integrated Device Technology (IDT). Following corporate acquisitions, production and support were transferred to Renesas Electronics. This specific model provides reliable non-volatile-like performance for fast data retention in active circuits.
