70T651S12BF8

Memory IC Overview

The Renesas Electronics Corporation 70T651S12BF8 is a dual-port, asynchronous static random-access memory (SRAM) IC with a total storage capacity of 9 Mbit. The memory is organized as 256K words by 36 bits. It features a parallel interface with a maximum access time of 12 ns. The device operates within a supply voltage range of 2.4 V to 2.6 V and supports surface-mount installation in a 208-CABGA package measuring 15x15 mm. It is rated for an operating temperature range from -40°C to +85°C.

Memory IC Feature Summary

• Dual-port architecture enabling independent simultaneous access to the same memory array
• Asynchronous operation allowing flexible timing control without external clock synchronization
• Wide data bus width supporting high-bandwidth applications requiring 36-bit word access

Memory IC Applications

• High-performance networking equipment requiring fast packet buffering
• Telecommunications systems utilizing rapid data processing and storage
• Industrial automation controllers needing reliable volatile memory for real-time operations

Memory IC Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to potential counterfeit risks. Confirm RoHS compliance status as specific listings indicate non-compliance. Check current lifecycle status, as some sources identify this part as obsolete or end-of-life. Ensure packaging type matches system requirements, noting variations between tray and tape-and-reel options across different suppliers.

Memory IC Selection Notes

Select this component when a design requires independent read/write ports for concurrent data handling. The 36-bit data width suits error-correction code implementations common in telecommunications. Verify that the 2.4V to 2.6V supply voltage aligns with the system power rails. Consider the 208-CABGA package size for PCB layout constraints and thermal management capabilities within the specified industrial temperature range.
