70T3539MS133BCG

Memory IC Overview

The 70T3539MS133BCG is a synchronous dual-port static random-access memory (SRAM) manufactured by Renesas Electronics. It features an 18 Mbit storage capacity organized as 512K x 36 bits. The device supports a maximum clock frequency of 133 MHz with a typical access time of 4.2 ns. It operates within a supply voltage range of 2.4 V to 2.6 V and has a maximum power consumption current of 740 mA. The component is housed in a 256-CABGA package and is rated for commercial operating temperatures between 0°C and +70°C.

Memory IC Feature Summary

• Provides independent read/write operations at both Port A and Port B simultaneously via parallel interfaces.
• Supports high-speed data transfer through synchronous operation with a maximum clock frequency of 133 MHz.
• Integrates on-chip parity generation and checking logic for each 36-bit word to ensure data integrity.

Memory IC Applications

• High-performance networking equipment requiring low-latency packet buffering.
• Telecommunications infrastructure systems utilizing wide data buses.
• Industrial control systems needing reliable dual-port memory for concurrent processor access.

Memory IC Procurement Notes

Verify the specific suffix 'G' indicates RoHS compliance when sourcing this component. Confirm the package type matches the 256-CABGA specification for PCB layout compatibility. Check moisture sensitivity level requirements during handling and storage. Ensure the supply voltage aligns with the 2.4V to 2.6V operational range. Validate that the commercial temperature grade meets the system's environmental constraints.

Memory IC Selection Notes

Select this part when a 36-bit data width is required for system bus alignment. Choose this model over single-port variants if simultaneous independent access to the same memory array is necessary. Consider the 133 MHz speed grade for applications demanding minimal cycle latency. Evaluate the 2.5V power supply availability against the component's electrical specifications.
