24LC16BT/ST

Memory IC Overview

The Microchip Technology 24LC16BT/ST is a 16-Kbit Electrically Erasable PROM organized as eight blocks of 256 x 8-bit memory. It features a two-wire serial interface compatible with I²C protocols. The device operates within a voltage range of 2.5V to 5.5V and supports a maximum clock frequency of 400 kHz. Key electrical characteristics include a standby current of up to 5 μA at extended temperatures and an active read current of 1 mA. The component utilizes low-power CMOS technology and offers hardware write protection capabilities.

Memory IC Feature Summary

• Supports bidirectional two-wire serial communication protocol
• Includes Schmitt trigger inputs for noise suppression
• Features output slope control to eliminate ground bounce
• Provides hardware write protection for the entire memory array

Memory IC Applications

• Embedded systems requiring non-volatile data storage
• Industrial control applications operating in harsh environments
• Automotive electronics meeting AEC-Q100 qualification standards

Memory IC Procurement Notes

Verify that the specific ordering suffix corresponds to the TSSOP-8 package type, as the base model number covers multiple physical form factors. Confirm the temperature grade matches the required operational environment, specifically distinguishing between Industrial and Extended ranges. Ensure compatibility with the target system's I²C bus voltage levels before integration.

Memory IC Selection Notes

Select this component when a 16-Kbit capacity is sufficient for application requirements. Consider the TSSOP-8 package if space-constrained surface-mount assembly is necessary. Evaluate the 400 kHz speed limit against system timing constraints. Verify that the 2.5V minimum supply voltage aligns with the available power rails in the design architecture.

Memory IC Part Context

This part belongs to the 24XX16 family of serial EEPROMs manufactured by Microchip Technology. The family includes variants such as the 24AA16 and 24FC16, which differ primarily in operating voltage ranges and maximum clock frequencies. The 24LC16B series specifically targets standard 2.5V to 5.5V applications with industrial or extended temperature ratings.

Memory IC Replacement Considerations

Direct substitutes include other members of the 24LC16B family with different package options, such as 24LC16B-I/SN for SOIC-8 or 24LC16B-E/ST for extended temperature in TSSOP-8. Cross-reference pinouts and electrical specifications carefully when substituting.
