70T3599S133BFI

Memory IC Overview

The Renesas 70T3599S133BFI is a synchronous dual-port static random-access memory (SRAM) device. It features a storage capacity of 4.5 Mbit organized as 128K words by 36 bits. The component operates with a maximum clock frequency of 133 MHz and provides a typical access time of 4.2 ns. It requires a single 2.5V power supply voltage and utilizes a parallel interface for data transfer. The device is housed in a 208-pin CABGA package measuring 15x15 mm, designed for surface-mount installation.

Memory IC Feature Summary

• Supports simultaneous independent read/write operations on both ports without bus conflicts
• Utilizes synchronous architecture controlled by a single clock input for precise timing
• Integrates dedicated write enable controls for each port to manage data flow independently

Memory IC Applications

• High-speed digital signal processing systems requiring low-latency buffering
• Network switching equipment utilizing wide data buses
• Industrial automation controllers needing reliable volatile memory storage

Memory IC Procurement Notes

Verify the specific suffix 'I' indicates industrial temperature range compliance during sourcing. Confirm RoHS status as non-compliant based on available documentation. Check for moisture sensitivity level requirements before assembly. Ensure the 208-CABGA footprint matches the target PCB design. Validate that the 2.5V supply rail aligns with system power constraints.

Memory IC Selection Notes

Select this component when a wide 36-bit data path is required for high-throughput applications. Choose over single-port variants if concurrent host and peripheral access is necessary. Consider the 133 MHz speed grade for systems demanding faster cycle times than standard SRAMs provide. Verify compatibility with existing 2.5V logic levels in the design.

Memory IC Part Context

This part belongs to the 70T3599 series of synchronous dual-port SRAMs from Renesas. It shares architectural similarities with the 70V3599 series but differs in operating voltage and temperature specifications. The 70T variant typically targets industrial environments compared to commercial counterparts.

Memory IC Replacement Considerations

Direct substitutes include the 70V3599S133BF and 70V3599S166BF. Note that these alternatives operate at 3.3V rather than 2.5V, requiring voltage level translation or supply modification.
