CY7C106BN-15VC

Product Overview

The CY7C106BN-15VC from Cypress Semiconductor Corp is a volatile SRAM device with a 1 Mbit memory capacity organized as 256K x 4. It uses a parallel interface and asynchronous operation, with a 15 ns access time and a 15 ns write cycle time. The device operates from a 4.5 V to 5.5 V supply and is specified for an ambient operating temperature range of 0°C to 70°C. The package is a 28-BSOJ surface-mount case with a 0.300-inch, 7.62 mm body width, also identified as 28-SOJ.

Key Features

• 1 Mbit volatile SRAM with a 256K x 4 organization
• Parallel interface with 4-bit data organization
• Asynchronous operation with 15 ns access time and 15 ns write cycle time
• 4.5 V to 5.5 V supply voltage range
• 28-BSOJ surface-mount package with 0.300-inch, 7.62 mm width and 0°C to 70°C ambient rating

Applications

• Temporary data storage in electronic systems
• Working storage for embedded controllers and digital logic subsystems
• Buffering between parallel digital interfaces and processing elements
• Data retention during powered operation in 5 V circuits

Design & Procurement Notes

When selecting this device, confirm that the host controller supports a parallel SRAM interface with a 256K x 4 organization and can meet the 15 ns asynchronous timing requirements. The 4.5 V to 5.5 V supply range should be checked against the board power architecture, and the 0°C to 70°C ambient temperature range should be compared with the expected operating environment. Layout planning should account for the 28-BSOJ, 0.300-inch, 7.62 mm surface-mount footprint, including the alternate 28-SOJ package designation. For designs requiring different data widths, supply ranges, extended temperature operation, or nonvolatile retention, verify those requirements against the device specifications before selecting this part.
