24AA512T-I/CS17K

Memory IC Overview

The Microchip Technology 24AA512T-I/CS17K is a 512 Kbit Electrically Erasable PROM organized as one block of 64K x 8-bit memory. It features a two-wire serial interface compatible with I2C protocols. The device operates on a single supply voltage ranging from 1.7V to 5.5V, supporting maximum clock frequencies of 100 kHz below 2.5V and 400 kHz at or above 2.5V. It includes hardware write protection, Schmitt trigger inputs for noise suppression, and output slope control to eliminate ground bounce.

Memory IC Feature Summary

• Supports cascading up to eight devices on the same bus using configurable chip address inputs.
• Includes a 128-byte page write buffer for efficient data transfer operations.
• Features hardware write-protect capability via the WP pin to inhibit array writes.

Memory IC Applications

• Data logging in industrial environments
• Configuration storage for embedded systems
• Parameter retention in consumer electronics

Memory IC Procurement Notes

Verify the specific suffix 'CS17K' against official Microchip documentation to confirm package type and availability, as standard datasheets list common packages like SOIC, TSSOP, and DFN. Confirm that the 'I' designation matches the required -40°C to +85°C industrial temperature range for your application environment before finalizing orders.

Memory IC Selection Notes

Select this component when low power consumption is critical, given its standby current of 1 µA maximum. Ensure the system voltage remains within the 1.7V to 5.5V operating range. Consider the 400 kHz maximum clock speed if higher throughput than 100 kHz is required, noting that speeds are limited to 100 kHz below 2.5V.

Memory IC Part Context

This part belongs to the 24XX512 family of serial EEPROMs, which also includes the 24LC512 and 24FC512 variants. While sharing the same memory architecture and interface, the 24AA512 is distinguished by its ability to operate down to 1.7V, whereas other family members may have different voltage thresholds or clock speed capabilities.

Memory IC Replacement Considerations

Direct substitutes include other 24AA512 variants with different packaging such as 24AA512-I/SN (SOIC) or 24AA512-I/ST (TSSOP), provided the physical footprint matches the design. Cross-family replacements like 24LC512 require verification of minimum voltage requirements.
