72V70800PFG

Overview

The Renesas 72V70800PFG is a digital bus switch IC designed for time slot interchange (TSI) applications. It provides a non-blocking switching capacity of 512 x 512 channels at a serial bit rate of 8.192 Mbps. The device operates on a single 3.3 V power supply, with an operating voltage range of 3 V to 3.6 V. It features 3.3 V I/O with 5 V tolerant inputs and supports an operating temperature range from -40 °C to +85 °C. The component is housed in a 64-pin Thin Plastic Quad Flatpack (TQFP) package.

Feature Summary

• Supports 512 x 512 channel non-blocking switching at 8.192 Mb/s
• Accepts four serial data streams of 8.192 Mb/s
• Includes per-channel variable or constant throughput delay
• Features automatic identification of ST-BUS/GCI interfaces

Applications

• ST-BUS compatible digital switching systems
• Multi-chip switches transporting voice channels
• Concatenated data channel transport
• Microprocessor-controlled switching networks

Procurement Notes

Verify the specific suffix 'PFG' against official Renesas documentation to confirm the exact package type and tape/reel specifications. Ensure compatibility with required moisture sensitivity levels and lead-free manufacturing standards before procurement. Cross-reference the manufacturer part number with authorized distributors to confirm current availability status.

Selection Notes

Select this component when a high-density TSI solution is required for 3.3 V systems. It is suitable for designs needing programmable stream and channel control with processor mode interface. Consider the 64-pin TQFP footprint for board layout constraints. Verify input offset delay requirements for multi-chip synchronization needs.

Part Context

The 72V70800 belongs to the Renesas 72V series of digital bus switches. This family includes variants such as the 72V70800TFG and 72V70800PF8, which share similar functional capabilities but differ in packaging and shipping formats. The series is designed for telecommunications and data switching applications requiring reliable non-blocking performance.

Replacement Considerations

The IDT72V70800TFG is listed as an alias for this component. Verify pinout and electrical characteristics against the official datasheet before substitution. Other series members like the 72V70200PFG offer different pin counts and should be evaluated for mechanical fit.
