24LC16B-I/MC

Memory IC Overview

The Microchip Technology 24LC16B-I/MC is a 16-Kbit Electrically Erasable PROM organized as eight blocks of 256 x 8-bit memory. It features a two-wire I2C compatible serial interface with a maximum clock frequency of 400 kHz for VCC between 2.5V and 5.5V. The device operates on a single supply voltage ranging from 2.5V to 5.5V, with a typical standby current of 1 μA and active read current of 1 mA. It utilizes low-power CMOS technology and includes a 16-byte page write buffer with a self-timed erase/write cycle time of up to 5 ms.

Memory IC Feature Summary

• Supports bidirectional two-wire serial communication protocol compatible with I2C standards
• Includes hardware write-protect functionality via the WP pin to inhibit write operations
• Features Schmitt trigger inputs and output slope control for noise suppression and ground bounce elimination

Memory IC Applications

• Embedded systems requiring non-volatile data storage
• Industrial control applications within specified temperature ranges
• Automotive electronics utilizing AEC-Q100 qualified components

Memory IC Procurement Notes

Verify the specific package type matches the design requirements, as the 24LC16B series is available in multiple formats including DFN, MSOP, PDIP, SOIC, TDFN, TSSOP, UDFN, SOT-23, and CSP. Confirm that the industrial temperature grade (I) covers the operational environment, as extended grades are distinct. Ensure the ordering suffix corresponds exactly to the desired physical package and temperature rating to avoid compatibility issues.

Memory IC Selection Notes

Select this component when a 16-Kbit capacity with an I2C interface is required for low-power applications. The 24LC16B variant specifically supports operation down to 2.5V, distinguishing it from the 24AA16 which operates down to 1.7V. Consider the 8-lead DFN package for space-constrained surface-mount designs. Verify that the system bus speed does not exceed 400 kHz at the operating voltage.

Memory IC Part Context

This part belongs to the 24XX16 family of serial EEPROMs manufactured by Microchip Technology. The family includes the 24AA16, 24LC16B, and 24FC16, which share similar organizational structures but differ in minimum operating voltage and maximum clock frequency specifications. The 'MC' suffix denotes the 8-lead 2x3 DFN package configuration.
