CY7C164-35PC

Product Overview

CY7C164-35PC from Cypress Semiconductor Corp is a 64 Kbit volatile SRAM memory IC organized as 16K x 4. It uses a parallel memory interface and provides a 35 ns access time, with a 35 ns write cycle time for word and page operations. The device operates from a 4.5 V to 5.5 V supply and is specified for a 0°C to 70°C ambient operating temperature range. It is supplied in a through-hole 22-DIP (0.300 inch, 7.62 mm) package, also identified as 22-PDIP.

• Temporary buffering in instrumentation or control designs requiring 64 Kbit of SRAM

Design & Procurement Notes

The 4.5 V to 5.5 V supply range and 0°C to 70°C ambient operating temperature range should be matched to the system power and environmental design. The 16K x 4 parallel organization means the device presents 4 data bits per address, so system bus width and address mapping must be planned accordingly. The 35 ns access and 35 ns write cycle times should be checked against controller timing margins. The through-hole 22-DIP package supports socketed or soldered placement, and board layout should account for its mounting footprint.
