71V124SA20PHG

Overview

The IDT71V124SA20PHG is a standard static random-access memory (SRAM) integrated circuit manufactured by Integrated Device Technology. It features a memory organization of 128K words by 8 bits, providing a total capacity of 1 Megabit. The device operates with an asynchronous interface and has a maximum access time of 20 nanoseconds. It utilizes CMOS technology and is housed in a 32-pin Thin Shrink Small Outline Package (TSOP II). The component supports a supply voltage range typically between 3.0 V and 3.6 V.

Feature Summary

• Asynchronous parallel data interface for flexible system integration
• CMOS technology ensuring low power consumption during operation
• Standard SRAM architecture suitable for general-purpose data storage

Applications

• General-purpose data buffering in embedded systems
• Cache memory applications in microprocessor-based designs
• Data storage in industrial control equipment

Procurement Notes

Verify the specific manufacturer source, as IDT assets were acquired by Renesas Electronics. Confirm RoHS compliance status and package variant accuracy against current datasheets. Check for product discontinuance notices or last-time-buy deadlines associated with this part number before finalizing procurement plans.

Selection Notes

Select this component when a 128Kx8 asynchronous SRAM with 20ns speed is required. Ensure the design accommodates the 32-pin TSOP II footprint. Verify voltage compatibility with the target system's 3V to 3.6V logic levels. Consider pinout compatibility if replacing existing designs using similar IDT 71V124 series parts.

Part Context

This part belongs to the IDT 71V124 family of 1-Mbit SRAMs. Variants within this family differ primarily in access speed (e.g., 10ns, 15ns, 20ns) and package options. The 'PHG' suffix typically denotes a lead-free, green TSOP II package compliant with environmental standards. This specific model represents the 20ns speed grade within the 32-pin form factor.

Replacement Considerations

Check for direct replacements from Renesas Electronics, which acquired IDT. Verify equivalent parts such as other 71V124 variants with matching speed and package. Cross-reference with Alliance Memory equivalents if available.
