71V3576YS150PF

Overview

The IDT71V3576YS150PF is a high-speed synchronous SDRAM SRAM component manufactured by Integrated Device Technology. It features a memory organization of 128K x 36 bits, providing a total capacity of 4.5 Mbits. The device supports a maximum clock frequency of 150 MHz with a clock access time of 3.8 ns. It operates on a 3.3V core power supply and utilizes a parallel interface. The component is housed in a 100-pin plastic thin quad flatpack (TQFP) package.

Feature Summary

• Supports high system speed with 150 MHz clock frequency and 3.8 ns access time
• Features burst counter and single cycle deselect for optimized performance
• Includes self-timed write cycle with global write control and byte write enable capabilities
• Offers optional boundary scan JTAG interface compliant with IEEE 1149.1

Applications

• High-performance cache memory systems
• Network infrastructure equipment
• Telecommunications base stations
• Industrial control systems requiring fast data access

Procurement Notes

Verify the specific suffix 'YS150PF' against official Renesas or IDT documentation to confirm pinout, voltage levels, and RoHS compliance status. Ensure the source document explicitly lists this part number as active or available, as older IDT memory parts may have been discontinued or superseded by newer revisions. Cross-reference the manufacturer's latest datasheet for any packaging or environmental changes.

Selection Notes

Select this component when a 128K x 36 organization is required for wide data bus applications. The 150 MHz speed grade suits designs needing low latency without the complexity of asynchronous interfaces. Consider the TQFP package constraints for PCB layout. Verify that the 3.3V I/O logic levels are compatible with the host processor or FPGA interface requirements.

Part Context

This part belongs to the IDT 71V3576/78 family of 3.3V Synchronous SRAMs. These devices are designed for high-speed data buffering and caching in embedded systems. The family includes variants with different speeds and organizations, such as 256K x 18 configurations. The 'Y' suffix typically denotes a specific temperature range or package variant within the product line.

Replacement Considerations
