70T3339S166BC

Memory IC Overview

The 70T3339S166BC is a high-speed synchronous dual-port static random-access memory manufactured by Renesas Electronics. It features a memory organization of 512K x 36 bits, providing a total capacity of 18 Mbit. The device supports an I/O clock frequency of 166 MHz with a corresponding access time of 3.6 ns. It operates on a single 2.5V power supply for both the core and I/Os. The component is housed in a 256-pin CABGA package measuring 17.0 mm by 17.0 mm. It includes JTAG functionality and selectable output modes.

Memory IC Feature Summary

• Dual-port architecture enables simultaneous independent access to shared memory locations from two distinct processors or systems.
• Supports selectable pipelined or flow-through output modes to optimize data throughput based on specific application latency requirements.
• Integrates JTAG boundary scan capability within the BGA package for enhanced manufacturing testability and system diagnostics.
• Features automatic power-down control via chip enable signals to minimize standby power consumption during idle periods.

Memory IC Applications

• High-performance networking equipment requiring low-latency packet buffering
• Telecommunications infrastructure utilizing synchronous data transfer protocols
• Industrial automation systems demanding reliable dual-processor data exchange

Memory IC Procurement Notes

Verify component authenticity through authorized channels due to potential availability constraints. Confirm RoHS compliance status as some variants may not meet current environmental standards. Validate package integrity upon receipt to ensure proper pin alignment. Check datasheet revisions for any functional updates prior to final design integration.

Memory IC Selection Notes

Select this component when 18-bit wide data paths and 166 MHz synchronous operation are required. Ensure the design accommodates the 256-pin CABGA footprint and thermal characteristics. Verify that the system voltage aligns with the specified 2.5V requirement for both core and I/O domains.
