CY7C1380D-167AXI

Product Overview

The CY7C1380D-167AXI from Cypress Semiconductor Corp is a 18Mbit synchronous SRAM memory IC with a parallel interface and a 512K x 36 organization. It operates from a 3.135V to 3.6V supply and supports a 167 MHz clock frequency with a 3.4 ns access time. The device uses a 100-TQFP (14x20) surface-mount package and a 100-LQFP package/case, and it is specified for an operating temperature range of -40°C to 85°C (TA). As a volatile SRAM, it retains stored data only while powered.

Key Features

• 18Mbit SRAM capacity arranged as 512K x 36.
• Synchronous, SDR memory technology with a 167 MHz clock frequency.
• Parallel interface and 3.4 ns access time.
• Volatile memory type; data is retained only while powered.
• 3.135V to 3.6V supply voltage range.
• 100-TQFP (14x20) surface-mount package with a 100-LQFP package/case.
• -40°C to 85°C (TA) operating temperature range.

Applications

• Embedded processing boards that use parallel SRAM for temporary data storage.
• Memory subsystems for controllers or processors requiring a 512K x 36 data organization.
• High-rate data buffering in communications or measurement equipment.
• Board-level memory expansion in systems with a compatible 3.135V to 3.6V supply.

Design & Procurement Notes

When selecting this part for a board design, verify that the power supply can maintain 3.135V to 3.6V across the operating temperature range and that the system clock is compatible with the 167 MHz clock frequency. The 512K x 36 organization and parallel interface should be matched to the controller or processor bus width. Layout should account for the 100-TQFP (14x20) surface-mount footprint and the 3.4 ns access time, which can affect timing margin and routing of the parallel bus. The volatile memory type means data is retained only while the device is powered.
