71T016SA15PH

Overview

The IDT71T016SA15PHI is a standard static random-access memory (SRAM) integrated circuit manufactured by Integrated Device Technology. It features a memory density of 1 Megabit, organized as 64K words by 16 bits. The device utilizes CMOS technology and operates with a 2.5V supply voltage. It offers a maximum access time of 15 nanoseconds. The component is housed in a 44-pin Thin Shrink Small Outline Package (TSOP II), specifically identified as PDSO44 with a 0.400-inch width. It supports asynchronous parallel interface operations.

Feature Summary

• Provides high-speed asynchronous data access with a 15ns cycle time for efficient system integration.
• Utilizes low-voltage 2.5V CMOS technology to reduce power consumption while maintaining performance.
• Features a compact 44-pin TSOP II surface-mount package suitable for space-constrained designs.

Applications

• Data buffering in embedded systems requiring fast temporary storage.
• Cache memory implementation in microprocessor-based architectures.
• Industrial control systems utilizing asynchronous logic interfaces.

Procurement Notes

Verify the specific suffix 'I' indicates the lead-free and RoHS-compliant variant when sourcing replacements. Confirm that the manufacturer has transitioned to Renesas Electronics, as legacy IDT product lines are now managed under the new corporate entity. Ensure compatibility with 2.5V logic levels in the target circuit design before procurement.

Selection Notes

Select this component for applications requiring 16-bit wide data paths at 15ns speeds within a 2.5V environment. Compare against the 71V016 series if 3.3V operation is required instead. Consider the TSOP-44 footprint constraints during PCB layout planning. Verify that the asynchronous interface aligns with the controller's timing requirements without needing synchronous clocking.

Part Context

This part belongs to the IDT 71T/71V SRAM family, which provides non-volatile-like speed with volatile storage capabilities. The '71T' designation typically refers to the 2.5V process node, distinguishing it from the 3.3V '71V' variants. These devices were widely used in telecommunications and computing infrastructure prior to broader industry shifts toward higher-density alternatives.
