Overview
The Renesas Electronics Corporation 7133SA35PF8 is a dual-port static random-access memory (SRAM) integrated circuit. It provides a storage capacity of 32 kilobits, organized as 2K words by 16 bits. The device features asynchronous parallel interface operation with a maximum access time of 35 nanoseconds. It operates within a supply voltage range of 4.5 volts to 5.5 volts and supports surface-mount installation in a 100-pin thin quad flat package.
Feature Summary
- Supports simultaneous independent access from two ports for concurrent read or write operations
- Enables direct port-to-port communication through on-chip interrupt flag signals
- Incorporates automatic power-down logic to minimize standby current consumption
Applications
- High-speed data buffering in industrial control systems
- Real-time signal processing applications requiring low latency
- Embedded systems needing concurrent processor access to shared memory
Procurement Notes
Verify component authenticity through authorized channels due to end-of-life status. Confirm moisture sensitivity level handling requirements during assembly. Check RoHS compliance specifications against project constraints. Validate pin compatibility with existing PCB footprints before integration.
Selection Notes
Evaluate the 35 nanosecond access speed against system timing requirements. Ensure the 100-pin TQFP package fits available board space. Consider the 4.5V to 5.5V operating voltage range for power supply design. Assess thermal performance within the specified temperature limits.
Part Context
This component belongs to the 7133SA series of dual-port SRAMs manufactured by Renesas Electronics. The series offers various speed grades and package options for different application needs. The 7133SA35 variant specifically targets applications requiring moderate speed with high reliability.
Replacement Considerations
The 7133LA20PFG8 is listed as a similar replacement option. Verify functional equivalence regarding access times and pin configurations before substitution.
