71T75802S166BG8

Overview

The Renesas Electronics Corporation 71T75802S166BG8 is a 18 Mbit Synchronous Static Random Access Memory (SRAM) organized as 1M x 18. It operates at a maximum clock frequency of 200 MHz with an access time of 3.2 ns. The device utilizes a 2.5 V core voltage and supports parallel interface communication. It is housed in a 119-pin PBGA package measuring 14x22 mm. The component functions within a temperature range of 0°C to +70°C and draws a maximum power supply current of 275 mA.

Feature Summary

• Zero Bus Turnaround (ZBT) architecture eliminates dead cycles between read and write operations.
• Single R/W control pin simplifies bus direction management without separate output enable signals.
• Internally synchronized output buffer enable registers address, data, and control signals for pipelined applications.
• Supports four-word burst capability in either interleaved or linear modes.

Applications

• High-performance embedded systems requiring fast memory access
• Network infrastructure equipment
• Industrial automation controllers
• Telecommunications base stations

Procurement Notes

Verify component authenticity through authorized distributors due to discontinuation status. Confirm moisture sensitivity level handling requirements during storage and assembly. Check for RoHS compliance documentation updates. Ensure packaging integrity matches specified reel or cut tape formats. Validate lead availability through official Renesas channels given limited stock conditions.

Selection Notes

Select this model when ZBT performance is required for 18-bit wide data paths. Compare against 16-bit variants if narrower interfaces suffice. Consider thermal dissipation limits within the 119-pin BGA footprint. Verify voltage compatibility with existing 2.5V system rails. Assess board space constraints against the 14x22 mm package dimensions.

Part Context

Part of the 71T75802 series offering synchronous SRAM solutions with zero bus turnaround technology. Designed to replace older asynchronous memories in high-speed digital systems. Manufactured by Renesas Electronics Corporation under the IDT brand lineage. Available in multiple speed grades and package options including TQFP and BGA configurations.

Replacement Considerations

IDT71T75802S166BG8 serves as an equivalent designation. Cross-reference pinouts and electrical characteristics before substitution. Verify package compatibility for direct replacement scenarios. Consult manufacturer datasheets for detailed parameter matching.
