24LC00-I/ST

Memory IC Overview

The Microchip Technology 24LC00-I/ST is a 128-bit (16 x 8) serial Electrically Erasable PROM featuring an I²C-compatible 2-wire interface. It operates on a single supply voltage ranging from 2.5V to 5.5V and supports clock frequencies of up to 400 kHz. The device utilizes low-power CMOS technology, ensuring typical active current consumption of 500 µA and standby current of 100 nA. It is housed in an 8-lead TSSOP package and is rated for industrial temperature operation between -40°C and +85°C.

Memory IC Feature Summary

• Supports bidirectional data transfer via a standard 2-wire serial bus protocol compatible with I²C.
• Incorporates Schmitt Trigger inputs and noise filtering circuits to suppress signal spikes on the SDA and SCL lines.
• Features output slope control mechanisms designed to eliminate ground bounce during switching operations.
• Includes internal VCC threshold detection to prevent invalid writes when power supply levels are insufficient.

Memory IC Applications

• Storage of calibration values in embedded systems
• Retention of identification numbers for device tracking
• Recording manufacturing information during production

Memory IC Procurement Notes

Verify that the specific ordering suffix corresponds to the required package type and temperature range. Confirm that the system design accommodates the 2.5V minimum operating voltage requirement. Ensure pull-up resistors are selected appropriately for the target bus speed to maintain signal integrity. Check for any recent Product Change Notifications regarding packaging or material composition updates.

Memory IC Selection Notes

Select this component when a minimal non-volatile memory footprint is sufficient for application requirements. Consider the TSSOP package geometry for surface-mount assembly constraints. Evaluate the 400 kHz maximum clock frequency against system timing needs. Verify compatibility with the master controller's I²C voltage levels and drive capabilities.

Memory IC Part Context

This device belongs to the 24XX00 family of serial EEPROMs, which includes variants like the 24AA00 and 24C00. These parts share similar functional architectures but differ in operating voltage ranges and specific electrical characteristics. The 24LC00 variant specifically targets applications requiring operation down to 2.5V, distinguishing it from lower-voltage or higher-voltage counterparts within the same series.
