71T75802S133PFG8

Overview

The Renesas Electronics Corporation 71T75802S133PFG8 is a synchronous static random-access memory (SRAM) integrated circuit with an 18 Mbit storage capacity. Organized as 1M x 18, it utilizes Zero Bus Turnaround (ZBT) technology to eliminate dead cycles between read and write operations. The device operates at a maximum clock frequency of 133 MHz with a 4.2 ns access time. It requires a core voltage supply ranging from 2.375 V to 2.625 V and supports a 2.5 V I/O interface. The component is housed in a 100-TQFP package measuring 14x14 mm and is rated for commercial operating temperatures between 0°C and 70°C.

Feature Summary

• Zero Bus Turnaround (ZBT) architecture eliminates bus turnaround dead cycles between read and write transitions.
• Fully pipelined design with internally synchronized output buffer enable and single R/W control pin.
• Supports four-word burst capabilities in either interleaved or linear modes.
• Includes boundary scan JTAG interface compliant with IEEE 1149.1 standards.

Applications

• High-performance embedded systems requiring fast data buffering
• Network infrastructure equipment utilizing parallel SRAM interfaces
• Industrial control systems needing reliable volatile memory storage

Procurement Notes

This component has been officially discontinued by the manufacturer. Verification of availability should focus on surplus distributors or authorized secondary markets. Confirm that the specific suffix PFG8 matches the required 100-TQFP package and commercial temperature range. Ensure compliance with RoHS3 regulations if applicable to the target assembly process, as older stock may vary in environmental certification status.

Selection Notes

Select this part when a 18 Mbit ZBT SRAM with 133 MHz performance is required in a 100-pin TQFP form factor. It serves as a direct replacement for legacy IDT71V65802 series devices within the same speed grade. Designers must account for the 2.5 V core voltage requirement and ensure PCB layout supports the parallel interface signals. Verify that the application environment remains within the 0°C to 70°C operational temperature limits specified for this package variant.

Part Context

The 71T75802 belongs to the broader 71T75802 family of synchronous ZBT SRAMs produced by Renesas Electronics. This family includes variants with different speeds, organizations, and packages, such as the 71T75802S133BG8 in a BGA package. The S133 designation indicates the 133 MHz speed bin, while PFG8 specifies the 100-TQFP plastic leaded chip carrier package with tape and reel shipping configuration.

Replacement Considerations

The 71T75902S75PFGI8 is listed as a similar alternative part number by the manufacturer. However, due to the discontinuation status, verify functional compatibility regarding speed, organization, and pinout before substitution.
