IDT71256SA12PZ8

Memory IC Overview

The IDT71256SA12PZ8 is a 32K x 8 asynchronous static random-access memory (SRAM) manufactured by Renesas Electronics. It features a storage capacity of 256 kbit with a maximum access time of 12 ns. The device operates on a single 5.0V power supply, with voltage limits ranging from 4.5V to 5.5V. It utilizes a parallel interface and is housed in a 28-pin TSOP package designed for surface-mount technology. The component supports standard dynamic random-access memory operations without requiring clocks or refresh cycles.

Memory IC Feature Summary

• Fully static asynchronous circuitry eliminates the need for external clock signals or periodic refresh cycles during operation.
• Integrated reduced power standby mode significantly lowers system-level power consumption and thermal requirements.
• Input and output pins are directly compatible with TTL logic levels for simplified interface design.

Memory IC Applications

• High-speed data buffering in industrial control systems
• Cache memory implementation in embedded computing architectures
• Battery-backed data retention applications requiring low-power standby states
