CY7C1356A-100AC

Product Overview

The Cypress Semiconductor Corp CY7C1356A-100AC is a synchronous SDR SRAM device with a 9 Mbit volatile memory capacity and a parallel interface. Its 512K x 18 organization provides a word-oriented memory structure for designs that use a 100 MHz clock and require a 7.5 ns access time. The device operates from a 3.135 V to 3.465 V supply and over an ambient operating temperature range of 0°C to 70°C. It uses a 100-TQFP (14x20) surface-mount package, supporting board-level integration in embedded memory subsystems.

Key Features

• 9 Mbit volatile SRAM memory capacity.
• Synchronous SDR technology with a parallel memory interface.
• 512K x 18 memory organization.
• 100 MHz clock frequency and 7.5 ns access time.
• 3.135 V to 3.465 V supply voltage range.
• 0°C to 70°C ambient operating temperature range.
• 100-LQFP / 100-TQFP (14x20) surface-mount package.

Applications

• Embedded systems that connect to a parallel synchronous SRAM bus and require volatile temporary data storage.
• Controller-based designs using a 512K x 18 memory organization for word-oriented buffer or scratch data.
• Surface-mount board designs that require a 100-TQFP memory device operating from a 3.135 V to 3.465 V supply.

Design & Procurement Notes

When selecting this part, design teams should confirm that the system power supply remains within 3.135 V to 3.465 V across load and temperature conditions. Because the device uses a parallel synchronous interface, timing closure should consider the 100 MHz clock and 7.5 ns access time alongside the controller and PCB propagation delays. The 512K x 18 organization and 100-TQFP (14x20) package should be checked against the intended memory map and board layout. The 0°C to 70°C operating range should be compared with the expected ambient conditions of the final assembly.
