71V3579S85PFG

Product Overview

The 71V3579S85PFG from IDT, Integrated Device Technology Inc is a volatile SRAM memory IC with a 4.5Mbit capacity and a 256K x 18 organization. It uses synchronous, single-data-rate technology and a parallel memory interface, supporting a clock frequency of 87 MHz and an access time of 8.5 ns. The device operates from a 3.135V to 3.465V supply and is specified for an ambient temperature range of 0°C to 70°C. It is offered in a 100-LQFP package, with a 100-TQFP (14x14) package designation, and is intended for surface mounting.

Key Features

• 4.5Mbit volatile SRAM with 256K x 18 organization
• Synchronous SDR memory operation with a parallel interface
• 87 MHz clock frequency and 8.5 ns access time
• 3.135V to 3.465V supply voltage range
• 0°C to 70°C operating temperature range
• 100-LQFP surface-mount package, 100-TQFP (14x14) package designation

Applications

• Embedded systems requiring local volatile data storage for temporary records
• Microprocessor or controller interfaces using a synchronous parallel bus for memory access
• Data acquisition systems needing SRAM buffering between processing stages

Design & Procurement Notes

For system design and procurement, confirm that the host controller is compatible with the 87 MHz clock frequency and the 256K x 18 organization. The 8.5 ns access time should be evaluated against the selected clock period and memory bus timing. Board layout should account for the 100-LQFP package, with the 100-TQFP (14x14) package designation, and provide a 3.135V to 3.465V supply. Thermal considerations should be based on the 0°C to 70°C ambient range. Because the memory is volatile, retain data only while power is maintained.
