24LC16B-I/ST

Memory IC Overview

The Microchip Technology 24LC16B-I/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, supporting a maximum clock frequency of 400 kHz for VCC ranges between 2.5V and 5.5V. The device operates within an industrial temperature range of -40°C to +85°C and utilizes low-power CMOS technology. Key electrical parameters include a maximum read current of 1 mA and standby current of 5 μA at extended temperatures. It offers hardware write protection via the WP pin and supports page writes up to 16 bytes.

Memory IC Feature Summary

• Supports bidirectional data transmission using a standard two-wire serial interface compatible with I²C protocols.
• Includes Schmitt trigger inputs and filter circuits on SCL and SDA pins to suppress noise spikes and ensure reliable operation in noisy environments.
• Features a hardware write-protect function that inhibits all write operations across the entire memory array when the WP pin is tied to VCC.
• Provides output slope control mechanisms designed to eliminate ground bounce during signal transitions.

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 I²C bus architectures for component communication

Memory IC Procurement Notes

Verify the specific suffix 'I/ST' corresponds to the Industrial temperature grade (-40°C to +85°C) and TSSOP-8 package type. Confirm RoHS compliance status and lead-free specifications against the latest manufacturer documentation. Ensure voltage requirements align with the 2.5V minimum operating threshold specified for the 24LC16B series.

Memory IC Selection Notes

Select this component when a 16-Kbit EEPROM with I²C compatibility is required for applications operating between 2.5V and 5.5V. Consider the 8-pin TSSOP package for surface-mount assembly constraints. Evaluate the need for hardware write protection if data integrity against accidental modification is critical for the system design.

Memory IC Part Context

This part belongs to the 24XX16 family of serial EEPROMs manufactured by Microchip Technology. The family includes variants like the 24AA16 and 24FC16, which differ primarily in operating voltage ranges and maximum clock frequencies. The 24LC16B specifically targets applications requiring operation down to 2.5V, distinguishing it from lower-voltage or higher-speed counterparts within the same product line.

Memory IC Replacement Considerations

Direct substitutes within the same package and specification include the 24LC16B-E/ST for extended temperature ranges. Other package variations such as 24LC16B-I/SN (SOIC) offer equivalent functionality with different physical footprints. Cross-family replacements like 24AA16 require verification of voltage level compatibility.
