IDT72V70800TF8

Overview

The IDT72V70800TF8 is a non-blocking digital Time Slot Interchanger (TSI) switch manufactured by Renesas Electronics. It provides a switching capacity of 512 x 512 channels at a serial bit rate of 8.192 Mb/s. The device operates on a single power supply ranging from 3 V to 3.6 V and supports an operating temperature range of -40°C to +85°C. It is housed in a 64-pin Thin Plastic Quad Flatpack (TQFP) package with dimensions of 10.0 x 10.0 mm. The component accepts four serial data streams and features programmable stream and channel control, processor mode, input offset delay, and high-impedance output control.

Feature Summary

• Supports 512 x 512 channel non-blocking switching at 8.192 Mb/s
• Accepts four serial data streams with automatic ST-BUS/GCI interface identification
• Features per-channel variable or constant throughput delay and high-impedance output control
• Includes per-stream frame delay offset programming for multi-chip switch management

Applications

• Digital telephone exchanges
• Telecommunications network infrastructure
• Voice and data channel concatenation systems
• ST-BUS compatible digital switching equipment

Procurement Notes

Verify the specific suffix 'F8' against official Renesas documentation to confirm packaging type and environmental compliance status. Ensure the procurement source provides valid RoHS and REACH compliance certificates. Confirm that the component matches the 64-TQFP physical footprint and electrical specifications before integration into designs requiring 3.3V operation.

Selection Notes

Select this component when designing systems requiring a 512x512 TSI matrix with 3.3V logic levels. It is suitable for applications needing precise frame offset calibration and high-impedance output control. Consider the 64-pin TQFP package constraints and the -40°C to +85°C industrial temperature range during board layout and thermal planning.

Part Context

This part belongs to the 72V series of digital bus switches and time slot interchangers. It is functionally related to variants such as the 72V70800TFG and 72V70800PF8, which share similar core switching capabilities but may differ in packaging or suffix designations. The IDT brand was integrated into Renesas Electronics, maintaining continuity in product lineage.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing system controllers and ensure pin-to-pin equivalence if considering alternative TSI devices from other manufacturers.
