71V3576S133PF

Overview

The IDT71V3576S133PF is a high-speed synchronous SRAM IC manufactured by Renesas Electronics Corporation, formerly IDT. It features a memory organization of 128K x 36, providing a total capacity of 4.5Mb. The device operates at a clock frequency of 133 MHz with a maximum access time of 4.2 ns. It utilizes a parallel interface and requires a supply voltage between 3.135V and 3.465V. The component is housed in a 100-TQFP (14x14) surface-mount package and supports an operating temperature range of 0°C to 70°C.

Feature Summary

• Supports high system speed with pipelined outputs for single-cycle deselect capability
• Features self-timed write cycles controlled by global write control and byte write enables
• Includes an optional boundary scan JTAG interface compliant with IEEE 1149.1 standards

Applications

• High-performance cache memory systems
• Network infrastructure equipment requiring fast data buffering
• Industrial control systems utilizing synchronous logic

Procurement Notes

Verify the current manufacturing status as this specific part number may be discontinued or obsolete. Confirm RoHS compliance requirements, as some variants are non-compliant. Ensure the supplier provides valid traceability documentation for vintage semiconductor components. Check for moisture sensitivity level handling instructions appropriate for MSL 3 classification during storage and assembly.

Selection Notes

Select this component when a 128K x 36 configuration is required for wide-data bus applications. The 133 MHz speed grade suits designs needing 4.2 ns access times without exceeding 3.3V I/O limits. Consider the 100-pin TQFP package constraints for PCB layout density. Evaluate power consumption profiles against system thermal management capabilities given the 3.3V core supply requirement.

Part Context

This device belongs to the IDT71V3576/78 family of 3.3V Synchronous SRAMs. It shares architectural similarities with other members like the IDT71V3576YS133PFG8 but differs in packaging suffixes and specific revision codes. The family is characterized by its burst counter functionality and support for both interleaved and linear burst modes within a standard 100-pin plastic thin quad flatpack form factor.

Replacement Considerations

Publicly confirmed substitute part numbers include IS61LPS12836A-200TQLI from ISSI. Verify pinout compatibility and electrical specifications before substitution.
