Overview
The Renesas 71V3577S80PFGI is a synchronous static random-access memory (SRAM) device organized as 128K x 36 bits, providing a total capacity of 4.5 Mbit. It operates with a maximum clock frequency of 100 MHz and features an access time of 8 ns. The component utilizes a parallel interface and requires a supply voltage between 3.135 V and 3.465 V. It is housed in a 100-pin TQFP package measuring 14x20 mm and supports commercial operating temperatures from 0°C to 70°C.
Feature Summary
- Supports synchronous burst architecture for high-speed data transfer
- Includes global write control and byte write enable capabilities
- Features power-down mode controlled by the ZZ input pin
Applications
- High-performance computing systems requiring fast memory access
- Network infrastructure equipment
- Industrial automation controllers
Procurement Notes
Verify current availability status as this part may be obsolete or end-of-life. Confirm that the 100-TQFP package dimensions match your PCB footprint requirements. Ensure the 3.3V I/O voltage levels are compatible with your system logic. Check for RoHS compliance status if required by your manufacturing standards.
Selection Notes
Select this component when a 128K x 36 organization is necessary for wide data bus applications. The 8 ns access time suits designs needing moderate-to-high speed synchronization. Consider the 100-pin TQFP package for surface-mount assembly constraints. Verify thermal performance within the 0°C to 70°C commercial range.
Part Context
This device belongs to the 71V3577 family of high-speed synchronous SRAMs. It shares architectural similarities with other members like the IDT71V3557 series but offers specific timing and package variations. The 71V3577 series is designed for applications demanding reliable, low-latency memory storage with synchronous interface protocols.
Replacement Considerations
Publicly confirmed substitute part numbers include IS61NLF12836A-7.5TQLI from ISSI. Verify electrical compatibility and pinout alignment before substitution.
