CYDC064B08-55AXI

Product Overview

The CYDC064B08-55AXI from Cypress Semiconductor Corp is a volatile SRAM device organized as 8K x 8, providing 64Kbit of memory behind a parallel interface. The device incorporates dual-port MoBL technology and is offered in a 100-LQFP / 100-TQFP (14x14) surface-mount package. Specified timing includes a 55 ns access time and 55 ns write cycle time, while supply options include 1.7V to 1.9V, 2.4V to 2.6V, and 3V to 3.6V. The operating temperature range is -40°C to 85°C (TA).

Key Features

• Volatile SRAM memory format with 64Kbit capacity and 8K x 8 organization.
• Dual-port MoBL technology.
• Parallel memory interface with 55 ns access time and 55 ns write cycle time.
• Supply voltage ranges of 1.7V to 1.9V, 2.4V to 2.6V, and 3V to 3.6V.
• 100-LQFP / 100-TQFP (14x14) surface-mount package.
• Operating temperature range of -40°C to 85°C (TA).

Applications

• Volatile data buffering between two parallel-bus controllers or processing blocks in embedded systems.
• Temporary storage for small lookup tables, queues, or scratchpad data in memory-constrained designs.
• Board-level memory expansion where a parallel interface, dual-port access, and 8K x 8 organization match the host architecture.

Design & Procurement Notes

Design considerations center on matching the selected supply range, confirming that the host parallel bus can operate with 55 ns access and write cycle timing, and allocating board space for the 100-TQFP (14x14) surface-mount package. The 8K x 8 organization and dual-port MoBL architecture make the device relevant to systems that need a compact volatile memory block with parallel interface characteristics. Thermal and timing margins should be checked against the -40°C to 85°C (TA) operating range when used in the target assembly.
