24LC16BT-I/OT

Memory IC Overview

The Microchip Technology 24LC16BT-I/OT is a 16-Kbit Electrically Erasable PROM organized as eight blocks of 256 x 8-bit memory. It operates with a single supply voltage ranging from 2.5V to 5.5V and supports a maximum clock frequency of 400 kHz. The device utilizes a two-wire serial interface compatible with I²C protocols. Key electrical characteristics include a maximum read current of 1 mA, standby current of 5 μA at extended temperatures, and an access time of 900 ns. It features a 16-byte page write buffer and a maximum page write time of 5 ms. The component is housed in a 5-lead SOT-23 package and is rated for industrial operating temperatures between -40°C and +85°C.

Memory IC Feature Summary

• Supports bidirectional two-wire serial communication protocol compatible with I²C standards
• Includes hardware write protection via the WP pin to inhibit write operations when tied to VCC
• Features Schmitt trigger inputs and output slope control to suppress noise and eliminate ground bounce
• Provides acknowledge polling capability to maximize bus throughput during internal write cycles

Memory IC Applications

• Embedded systems requiring non-volatile data storage for configuration parameters
• Industrial control devices needing reliable memory under varying temperature conditions
• Consumer electronics utilizing low-power microcontrollers with limited I/O resources
• Automotive applications qualified under AEC-Q100 standards for durability

Memory IC Procurement Notes

Verify that the specific ordering suffix matches the required package type and temperature grade. Confirm that the voltage range requirements align with the 2.5V minimum specification for the 24LC16B series. Ensure compatibility with the I²C bus speed limits defined for the selected supply voltage. Check for RoHS compliance status if environmental regulations apply to the final assembly process.

Memory IC Selection Notes

Select this component when a compact surface-mount solution is required for small capacity non-volatile storage. The 5-lead SOT-23 package offers space efficiency compared to standard 8-pin variants. Consider the 400 kHz clock limit when designing high-speed data acquisition systems. Evaluate the power consumption profiles against battery-operated constraints given the low standby current specifications.

Memory IC Part Context

This part belongs to the 24XX16 family of serial EEPROMs manufactured by Microchip Technology. The family includes variations such as the 24AA16 and 24FC16, which differ primarily in operating voltage ranges and maximum clock frequencies. The 'I' designation indicates an industrial temperature range, while 'OT' specifies the 5-lead SOT-23 packaging format. These devices share common functional architectures but are distinguished by their electrical ratings and physical dimensions.

Memory IC Replacement Considerations

Direct substitutes within the same package and electrical specifications include other 24LC16B variants in different packages, such as 24LC16BT-I/SN or 24LC16BT-I/MNY. Cross-family replacements like the 24AA16 require verification of the lower 1.7V operating voltage support. Ensure that any replacement maintains the 400 kHz maximum clock frequency constraint for equivalent performance.
