Overview
The Renesas Electronics Corporation 7134SA70CB is a dual-port static random access memory (SRAM) device with a storage capacity of 32 kbit, organized as 4K x 8. It features an asynchronous parallel interface and a maximum access time of 70 ns. The component operates within a supply voltage range of 4.5 V to 5.5 V and has a maximum power supply current of 240 mA. It is housed in a CDIP-SB-48 package designed for through-hole mounting. The device supports an operating temperature range from 0°C to +70°C.
Feature Summary
- Dual-port architecture enabling independent simultaneous access by two processors
- Asynchronous operation via parallel interface for flexible system integration
- CMOS technology providing high-speed data retention capabilities
Applications
- High-performance embedded systems requiring concurrent data access
- Industrial control units needing reliable volatile memory storage
- Telecommunications equipment utilizing dual-processor architectures
Procurement Notes
This component is officially listed as End-of-Life (EOL) by the manufacturer. Distribution availability is restricted or non-existent in many regions. Verify specific lot dates and authenticity carefully when sourcing from secondary markets due to discontinuation status.
Selection Notes
Select this part only if legacy compatibility with the 7134SA series is required. Ensure the design accommodates the CDIP-SB-48 through-hole package constraints. Consider the 70 ns access speed against modern alternatives if performance upgrades are feasible for the target application.
Part Context
The 7134SA70CB belongs to the Renesas 7134SA family of dual-port SRAMs. It shares functional similarities with other variants like the 7134SA70J but differs in packaging and thermal specifications. This series was widely used in applications demanding independent read/write ports without external arbitration logic.
Replacement Considerations
Public confirmed substitute part numbers are not available for this discontinued component. Evaluate cross-reference options such as IDT7134SA70CB equivalents or newer dual-port SRAM families from Renesas or other manufacturers based on pinout and electrical compatibility.
