70T3509MS166BPI

Memory IC Overview

The Renesas 70T3509MS166BPI is a high-speed synchronous dual-port static random-access memory (SRAM) IC. It features a storage capacity of 36 Mbit, organized as 1 Megabit by 36 bits. The device supports a maximum clock frequency of 166 MHz with an access time of 3.6 ns. It operates within a supply voltage range of 2.4 V to 2.6 V and utilizes LVTTL interface logic. The component is housed in a 256-pin CABGA package measuring 17x17 mm.

Memory IC Feature Summary

• True dual-port architecture enabling simultaneous independent access to the same memory location from two separate ports.

Memory IC Applications

• High-performance computing systems requiring fast data buffering
• Network routing equipment needing low-latency packet processing
• Industrial automation controllers demanding reliable synchronous memory

Memory IC Procurement Notes

Verify RoHS compliance status and moisture sensitivity level before procurement. Confirm package dimensions match PCB footprint requirements. Check for end-of-life notices or alternative part recommendations from the manufacturer. Ensure supply chain stability due to potential long lead times for specialized memory components.

Memory IC Selection Notes

Select this component when simultaneous bidirectional data access is required without arbitration delays. Suitable for applications where deterministic latency is critical. Compare against single-port alternatives if only one processor accesses memory. Verify voltage compatibility with system power rails.
