7134SA35P

Overview

The Renesas 7134SA35P is a high-speed, asynchronous dual-port static random-access memory (SRAM) with a storage capacity of 32 kilobits. The memory organization is specified as 4K words by 8 bits. It features parallel interface access with a maximum access time of 35 nanoseconds. The device operates on a single TTL-compatible 5V power supply, ranging from 4.5V to 5.5V. It is housed in a 48-pin ceramic dual in-line package with sidebend leads (CDIP-SB-48).

Feature Summary

• True dual-ported memory cells allow simultaneous independent access to the same memory location from both ports.
• Fully asynchronous operation eliminates the need for clock synchronization between the two ports.
• Automatic power-down feature controlled by chip enable signals permits entry into low standby power mode.

Applications

• Systems requiring external arbitration for simultaneous port access without hardware port arbitration logic.
• Applications designed to tolerate or withstand contention when both sides access the same Dual-Port RAM location.
• Industrial systems where wait states are not tolerated and high-speed data transfer is required.

Procurement Notes

Verify the specific suffix 'P' against official datasheets to confirm the package type and temperature range. Confirm RoHS compliance status as older CDIP variants may differ. Check for active production status or obsolescence notices via manufacturer channels before procurement.

Selection Notes

Select this component for designs requiring true dual-port capability with asynchronous timing. Ensure the system architecture can handle potential bus contention during simultaneous accesses. Verify that the 48-pin CDIP package fits the mechanical constraints and thermal requirements of the target application.

Part Context

This part belongs to the 7134 series of dual-port SRAMs. It shares architectural similarities with other members like the 7134LA series but differs in speed grade and voltage retention capabilities. The SA designation typically indicates standard 5V operation without battery backup support found in LA variants.
