70T659S10BC8

Memory IC Overview

The 70T659S10BC8 is a high-speed asynchronous dual-port static RAM manufactured by Renesas Electronics. It features a memory organization of 256K x 36 bits, providing a total density of 9 Mbit. The device operates with a supply voltage range of 2.4V to 2.6V and supports a maximum access time of 10 ns. It utilizes a parallel interface and is housed in a 256-pin CABGA package measuring 17x17 mm. The component is designed for surface mount installation and functions within an operating temperature range of 0°C to 70°C.

Memory IC Feature Summary

• Supports independent read/write operations on both ports simultaneously without conflict
• Enables cascading multiple units to form wider memory systems without external logic
• Includes automatic power-down modes controlled by chip select inputs

Memory IC Applications

• High-performance computing systems requiring fast data buffering
• Telecommunications equipment needing low-latency memory access
• Industrial control systems utilizing master/slave dual-port configurations

Memory IC Procurement Notes

Verify the specific suffix BC8 against official Renesas documentation to confirm pinout compatibility and package dimensions. Confirm RoHS compliance status as historical IDT variants may differ. Check current production lifecycle status to ensure availability for new designs. Validate moisture sensitivity level requirements for your assembly process. Ensure supply chain sources provide genuine Renesas or IDT branded components.

Memory IC Selection Notes

Select this component when a 9 Mbit capacity with 36-bit word width is required. Choose this part if a 10 ns access speed meets system timing constraints. Opt for this device if a 256-pin BGA package fits the board layout. Consider this option for applications needing simultaneous dual-port access capabilities.

Memory IC Part Context

This part belongs to the 70T659 family of dual-port SRAMs originally developed by Integrated Device Technology (IDT) and now produced by Renesas Electronics. The family offers various access speeds and package options. The 70T659 series is widely used in networking and storage applications where high bandwidth and concurrent port access are critical for system performance.

Memory IC Replacement Considerations

Official cross-reference documents list IDT70T659S10BC8 as an alias. Verify electrical parameters match exactly before substitution. Check for any pinout differences between legacy IDT and current Renesas manufacturing batches.
