CY7C1046D-10VXI

Product Overview

The Cypress Semiconductor Corp CY7C1046D-10VXI is an asynchronous volatile SRAM device with a 4Mbit memory size organized as 1M x 4. It uses a parallel memory interface and provides a 10 ns access time, with a 10 ns write cycle time for word and page operations. The device operates from a 4.5V to 5.5V supply and is specified for an ambient temperature range of -40°C to 85°C. It uses a surface-mount 32-SOJ package, also described as 32-BSOJ with a 0.400 inch (10.16 mm) width.

Key Features

• 4Mbit volatile SRAM memory with 1M x 4 organization
• Asynchronous SRAM technology with a parallel memory interface
• 10 ns access time and 10 ns write cycle time for word and page operations
• Supply voltage range of 4.5V to 5.5V
• Operating temperature range of -40°C to 85°C (TA)
• Surface-mount package: 32-SOJ / 32-BSOJ, 0.400 inch (10.16 mm) width

Applications

• Volatile data buffering in embedded controllers that use a parallel memory bus
• Temporary storage of measurement samples in data acquisition instruments
• Staging of communication protocol data in equipment using a parallel SRAM interface

Design & Procurement Notes

For the CY7C1046D-10VXI, verify that the system power rail remains within 4.5V to 5.5V and that the host logic can meet 10 ns access and write cycle timing. Because the device uses a 1M x 4 organization, plan address mapping and bus width accordingly, particularly when wider data paths are required. The surface-mount 32-SOJ/32-BSOJ footprint, with a 0.400 inch (10.16 mm) body width, should be considered during PCB layout and reflow process planning. The -40°C to 85°C ambient operating range supports thermal margin assessment for the final enclosure or board location.
