70T3339S133BC

Memory IC Overview

The 70T3339S133BC is a high-speed synchronous dual-port static random access memory (SRAM) manufactured by Renesas Electronics. It features a storage organization of 512K x 18 bits, providing a total capacity of 9 Mbit. The device supports a maximum clock frequency of 133 MHz with an access time of 4.2 ns. It operates on a single 3.3V power supply and utilizes a parallel interface. The component is housed in a 256-pin CABGA package measuring 17x17 mm.

Memory IC Feature Summary

• Simultaneous independent access to the same memory location from both ports without conflict
• Selectable pipelined or flow-through output modes for optimized data throughput
• Automatic power-down capability controlled by chip enables to minimize standby current
• Dual cycle deselect feature available for pipelined output mode operation

Memory IC Applications

• High-performance networking equipment requiring low-latency packet buffering
• Telecommunications systems utilizing burst data flow architectures
• Industrial control systems needing reliable simultaneous read/write operations
• Embedded processing applications demanding fast local memory expansion

Memory IC Procurement Notes

Verify the specific suffix designation against official Renesas documentation to confirm voltage and temperature grades. Confirm RoHS compliance status as historical batches may vary. Check for active discontinuation notices or end-of-life notifications prior to finalizing procurement plans. Ensure moisture sensitivity level handling procedures are followed during assembly.

Memory IC Selection Notes

Select this component when a 9 Mbit synchronous dual-port SRAM with 133 MHz performance is required. Ensure the design supports a 3.3V I/O interface and requires simultaneous port access. Verify that the 256-pin CABGA footprint fits the target PCB layout constraints. Consider alternative packages if different pin counts or thermal profiles are needed.
