CY7C1345A-100AC

Product Overview

The CY7C1345A-100AC from Cypress Semiconductor Corp is a volatile synchronous SRAM memory IC with a 4.5 Mbit capacity and a 128K x 36 organization. It uses a parallel interface, operates from a 3.15 V to 3.6 V supply, and is specified for a 100 MHz clock with an 8 ns access time. The device uses a 100-LQFP surface-mount package, with a 100-TQFP (14 x 14) device package, and is rated for an operating temperature range of 0°C to 70°C (TA). Its synchronous SDR SRAM technology supports systems that require a parallel memory path for temporary data storage and retrieval.

Key Features

• Volatile SRAM memory with a 4.5 Mbit capacity and 128K x 36 organization.
• Synchronous, SDR memory technology with a parallel interface.
• Specified clock frequency of 100 MHz and access time of 8 ns.
• Supply voltage range of 3.15 V to 3.6 V.
• Operating temperature range of 0°C to 70°C (TA).
• Surface-mount 100-LQFP package with a 100-TQFP (14 x 14) device package.

Applications

• Volatile working memory for embedded systems that use a parallel memory bus and a 3.15 V to 3.6 V supply.
• Synchronous buffering in logic designs operating with a 100 MHz clock.
• Storage of frequently accessed data in equipment within the 0°C to 70°C (TA) range.

Design & Procurement Notes

The CY7C1345A-100AC should be used on a 3.15 V to 3.6 V supply and within the 0°C to 70°C (TA) range. Its 128K x 36 organization and parallel interface require the system bus to accommodate 36 data bits and 128K addressable locations. Timing budgets should account for the 100 MHz synchronous clock and 8 ns access time. Board layout should support the 100-LQFP surface-mount package and the 100-TQFP (14 x 14) footprint.
