Overview
The 71V3577S75BGI8 is a synchronous static random access memory (SRAM) manufactured by Renesas Electronics. It features a storage organization of 128K x 36 bits, providing a total capacity of 4.5 Mbit. The device operates with a maximum clock frequency of 117 MHz and offers an access time of 7.5 ns. It utilizes a parallel interface and requires a supply voltage between 3.135 V and 3.465 V. The component is housed in a 119-pin PBGA package measuring 14x22 mm and supports surface mount installation.
Feature Summary
- Supports synchronous single data rate (SDR) operation for high-speed data transfer
- Provides flow-through output architecture for direct data availability
- Includes boundary scan JTAG interface compliant with IEEE 1149.1 standard
Applications
- High-performance computing systems requiring fast memory access
- Industrial equipment control units
- Network infrastructure hardware
Procurement Notes
Verify the current lifecycle status as this component may be subject to end-of-life notices or production discontinuation. Confirm moisture sensitivity level handling requirements during assembly. Ensure compatibility with existing board layouts regarding the 119-pin PBGA footprint and thermal specifications before procurement.
Selection Notes
Select this part when a 36-bit wide data bus is required for system integration. Consider the 7.5 ns access time for timing constraints in high-frequency designs. Verify that the 119-pin BGA package fits within the mechanical enclosure limits and that the 3.3V I/O logic levels match the host processor specifications.
Part Context
This component belongs to the 71V3577 series of synchronous SRAMs from Renesas. The series includes variants with different access times and packages, such as the 85 speed grade and TQFP options. The 71V3577S75BGI8 specifically denotes the 7.5 ns speed grade in the 119-pin BGA package configuration.
Replacement Considerations
Check for IDT71V3577S75BGI8 as a potential equivalent under prior branding. Evaluate other speed grades within the 71V3577 family if timing margins allow. Verify pinout compatibility before substituting with similar synchronous SRAM devices.
