CY7C1328A-133AI

Product Overview

The CY7C1328A-133AI from Cypress Semiconductor Corp is a volatile SRAM memory IC built for synchronous, single-data-rate operation. It provides 4.5Mbit of storage organized as 256K x 18 and uses a parallel memory interface. The device is specified for a 3.15V to 3.6V supply range and a clock frequency of 133 MHz, with a 4 ns access time. It is offered in a surface-mount 100-LQFP package, with the 100-TQFP (14x20) device package designation, and supports an operating temperature range of -40°C to 85°C.

Key Features

• 4.5Mbit volatile SRAM capacity with a 256K x 18 memory organization.
• Synchronous, single-data-rate memory architecture with a parallel interface.
• Rated for 133 MHz clock operation and a 4 ns access time.
• Operates from a 3.15V to 3.6V supply.
• Surface-mount 100-LQFP package, 100-TQFP (14x20) package designation.
• Temperature range of -40°C to 85°C.

Applications

• Synchronous data buffering in embedded systems that use a parallel bus.
• Temporary storage for word or data processing paths with a 256K x 18 organization.
• Embedded board designs requiring surface-mount SRAM in a 3.15V to 3.6V supply and -40°C to 85°C environment.

Design & Procurement Notes

Design considerations should focus on matching the 3.15V to 3.6V supply range, the 133 MHz synchronous clock, and the 4 ns access time to the host controller timing budget. The 256K x 18 organization and parallel interface require compatible address, data, and control bus planning. Board layout should account for the surface-mount 100-LQFP, 100-TQFP (14x20) package and the -40°C to 85°C operating temperature range. Procurement notes should confirm package designation and electrical parameters before integration.
