CY7C1006B-20VC

Product Overview

The Cypress Semiconductor Corp CY7C1006B-20VC is an asynchronous SRAM memory IC that provides 1Mbit of volatile storage in a 256K x 4 organization. It uses a parallel memory interface and supports a 4.5V to 5.5V supply range. The device is offered in a surface-mounted 28-SOJ package with a 28-BSOJ case width of 0.300 inches, or 7.62mm.

Key Features

• 1Mbit volatile SRAM memory with a 256K x 4 organization
• Asynchronous SRAM technology with a parallel memory interface
• 20 ns access time and 20 ns write cycle time for words or pages
• 4.5V to 5.5V supply voltage range
• Surface-mount 28-SOJ package with 28-BSOJ 0.300 inch, 7.62 mm width
• Operating temperature range from 0°C to 70°C (TA)

Applications

• Embedded controller systems that require parallel SRAM for temporary data storage
• Industrial control boards operating in ambient conditions from 0°C to 70°C
• Instrumentation designs using a parallel SRAM buffer for sampled data
• Data acquisition systems using parallel SRAM for temporary record buffers

Design & Procurement Notes

When selecting the CY7C1006B-20VC, confirm that the board supply can hold the device within 4.5V to 5.5V under load and transient conditions. The 20 ns access and write timing should be checked against the controller bus cycle requirements. The 28-SOJ surface-mount footprint and 7.62 mm body width need to match the PCB land pattern and neighboring components. The 0°C to 70°C ambient range should be verified for the enclosure and airflow conditions. The 256K x 4 organization means system hardware or firmware must accommodate the 256K x 4 parallel data path.
