7132SA25J8/C

Overview

The Renesas Electronics Corporation 7132SA25J8/C is a high-speed Dual-Port Static Random Access Memory (SRAM) component. It features a storage capacity of 16 kbit, organized as 2K x 8 bits. The device operates with an access time of 25 ns and utilizes a parallel interface. It supports a single power supply voltage range of 4.5 V to 5.5 V. The component is housed in a 52-pin PLCC package designed for surface mount installation.

Feature Summary

• True dual-ported memory cells enabling simultaneous independent access to the same memory location by both ports.
• Integrated on-chip port arbitration logic that manages bus conflicts without requiring external discrete logic components.
• Automatic power-down functionality controlled by chip enable signals to achieve low standby power consumption.
• TTL-compatible operation using a single 5V ±10% power supply.

Applications

• Stand-alone 8-bit dual-port RAM systems
• Master dual-port RAM configurations paired with slave devices for wider word width architectures
• High-speed data buffering applications requiring concurrent read/write operations

Procurement Notes

This component is officially designated as End-of-Life (EOL) and has been discontinued by the manufacturer. Production has ceased, and no new units are available from authorized channels. Verification of authenticity is critical when sourcing remaining stock from third-party distributors. Buyers must confirm the specific revision level and physical condition of available inventory, as original packaging may be compromised due to long-term storage.

Selection Notes

Designers should evaluate alternative components immediately due to the discontinuation status of this part. Selection criteria must focus on compatible pinouts, electrical specifications, and functional equivalence to ensure seamless integration into existing designs. Verify that potential replacements support the required dual-port arbitration and simultaneous access capabilities necessary for the target application architecture.
