IDT70824L25PF

Memory IC Overview

The IDT70824L25PF is a high-speed 64Kbit (4K x 16-bit) Sequential Access Random Access Memory (SARAM). It features a dual-port architecture with a standard asynchronous random access port and a clocked sequential access port. The device operates on a single 5V supply, consuming typical active power of 775mW and standby power of 1mW. It supports data retention down to 2V and is available in an 80-pin TQFP package.

Memory IC Procurement Notes

Verify component authenticity through authorized channels as the part may be obsolete. Confirm RoHS compliance status and specific speed grade availability. Ensure proper handling for static-sensitive devices during installation. Check for alternative sourcing options if lead times are critical.

Memory IC Selection Notes

Select this component when mixed sequential and random memory access is required within a single chip. Consider the low standby power consumption for battery-operated systems. Evaluate the 80-pin TQFP package constraints against board space requirements. Verify temperature range compatibility with the intended operating environment.

Memory IC Part Context

This SARAM belongs to the IDT70824 family, designed for high-performance memory buffering. It bridges the gap between standard SRAMs and specialized FIFOs by offering flexible buffer management. The device is suitable for applications demanding efficient data throughput with minimal controller overhead.

Memory IC Replacement Considerations

Check for direct pin-compatible replacements within the same speed grade. Verify functional equivalence regarding buffer control registers and timing parameters. Ensure voltage and power specifications match the existing design constraints.
