70T659S12BC8

Memory IC Overview

The Renesas Electronics Corporation 70T659S12BC8 is a dual-port static random-access memory (SRAM) device featuring an asynchronous parallel interface. It provides a storage capacity of 4.5 Mbit organized as 128K words by 36 bits. The component operates within a supply voltage range of 2.4V to 2.6V and supports surface-mount installation in a 256-CABGA package measuring 17x17 mm. It offers a maximum access time of 12 ns and functions reliably across an operating temperature range of 0°C to 70°C.

Memory IC Feature Summary

• Dual-port architecture enabling independent simultaneous access for two masters without discrete logic
• Asynchronous operation with standard parallel interface for flexible system integration
• Automatic power-down mode controlled by chip enable signals to reduce standby current

Memory IC Applications

• Master/Slave dual-port RAM configurations for 72-bit or wider word systems
• High-speed data buffering in industrial control networks
• Real-time processing units requiring low-latency memory access

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 this variant may not meet current environmental directives. Check for active production status or end-of-life notifications prior to design finalization. Ensure moisture sensitivity level handling procedures are followed during assembly.

Memory IC Selection Notes

Select this component when a 36-bit wide data path is required for dual-port applications. The 2.5V supply requirement distinguishes it from 3.3V variants like the 70V659 series. Consider the 12 ns access speed relative to system clock requirements. Evaluate the 256-CABGA package constraints for PCB layout and thermal management needs.

Memory IC Part Context

This part belongs to the 70T659 family of high-speed dual-port SRAMs designed for standalone or cascaded master/slave operations. It complements other members like the 70T659S12BFI and 70T651 series, offering varying densities and package options while maintaining consistent asynchronous timing characteristics for embedded memory solutions.

Memory IC Replacement Considerations

Official substitutes include IDT70T659S12BC8. Verify functional equivalence with 70T659S12BFI if package differences are acceptable.
