71V65803S133PFG

Overview

The Renesas Electronics Corporation 71V65803S133PFG is a 9 Mbit Synchronous ZBT SRAM organized as 512K x 18. It operates with a maximum clock frequency of 133 MHz and features a typical access time of 4.2 ns. The device supports a supply voltage range from 3.135 V to 3.465 V, with a maximum power consumption current of 195 mA. It utilizes a parallel interface and is housed in a 100-TQFP (14x14) surface-mount package. The component functions within an operating temperature range of 0°C to +70°C.

Feature Summary

• Supports synchronous single data rate (SDR) operations with zero wait state burst access capabilities.
• Integrates a pipelined output architecture for high-speed data throughput.
• Includes a dedicated burst counter for managing sequential memory accesses.

Applications

• High-performance embedded systems requiring fast local memory buffering
• Network infrastructure equipment needing low-latency data storage
• Industrial control units utilizing synchronous bus interfaces

Procurement Notes

Verify the specific suffix PFG against official Renesas documentation to confirm the 100-TQFP package and commercial temperature grade. Confirm RoHS compliance status through the latest datasheet revision, as manufacturing changes may affect regulatory markings. Check for end-of-life notices or production change notifications prior to finalizing procurement plans.

Selection Notes

Select this component when a 512K x 18 organization is required for synchronous applications. Ensure the design accommodates the 3.3V I/O logic levels and the 100-pin TQFP footprint. Compare performance metrics against alternative speeds if higher clock frequencies are necessary for the target system architecture.
