71V3556S166PFG

Product Overview

The 71V3556S166PFG from IDT, Integrated Device Technology Inc is a volatile SRAM memory integrated circuit with a 4.5Mbit capacity organized as 128K x 36. It uses a parallel interface and synchronous, single data rate ZBT technology, with a specified clock frequency of 166 MHz and an access time of 3.5 ns. The device operates from a 3.135 V to 3.465 V supply and is offered in a surface mount 100-TQFP package with a 14 mm by 14 mm body.

Key Features

• Volatile SRAM memory format with 4.5Mbit total capacity and 128K x 36 organization.
• Synchronous single data rate ZBT technology with a 166 MHz clock frequency.
• Parallel memory interface with a 3.5 ns access time.
• 3.135 V to 3.465 V supply voltage range.
• Operating temperature range of 0°C to 70°C (TA).
• Surface mount 100-TQFP package with 14 mm by 14 mm body dimensions.

Applications

• High-speed data buffering in network and communications equipment.
• Synchronous memory subsystem for embedded processors and digital signal processing platforms.
• Temporary storage for register files and lookup data in control systems.

Design & Procurement Notes

Designers should verify that the host logic or controller supports a parallel synchronous SRAM interface, 166 MHz timing, and 3.5 ns access characteristics. The 3.135 V to 3.465 V supply range requires regulated power rails and adequate decoupling for the 100-TQFP package. Because the memory is volatile, system designs should account for data retention only while powered. The 0°C to 70°C (TA) operating range and surface mount package should be considered during thermal and PCB layout planning, including signal integrity for the 128K x 36 parallel bus.
