24AA16T-I/MS

Memory IC Overview

The Microchip Technology 24AA16T-I/MS 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 1.7V to 5.5V and features a two-wire I2C compatible serial interface. The device supports a maximum clock frequency of 400 kHz when VCC is between 2.5V and 5.5V, and 100 kHz when VCC is between 1.7V and 2.5V. It includes a 16-byte page write buffer and hardware write-protect functionality via the WP pin. The component is housed in an 8-lead MSOP package and is rated for industrial temperature operation from -40°C to +85°C.

Memory IC Feature Summary

• Low-power CMOS technology enabling standby currents as low as 1 µA
• Hardware write-protect capability through the dedicated WP pin
• Schmitt trigger inputs and output slope control for noise suppression and ground bounce elimination
• Self-timed erase/write cycles with acknowledge polling support

Memory IC Applications

• Personal communications devices requiring non-volatile data storage
• Data acquisition systems needing low-power memory solutions
• Industrial control applications operating within the specified voltage range
• Embedded systems utilizing I2C bus architectures

Memory IC Procurement Notes

Verify that the ordering suffix corresponds to the MSOP package type and Industrial temperature grade. Confirm RoHS compliance status if required by specific manufacturing standards. Ensure the supplier provides documentation matching the DS20001703M datasheet revision. Check for any specific handling requirements related to moisture sensitivity levels indicated in the packaging information.

Memory IC Selection Notes

Select this component when a 16-Kbit capacity is sufficient for the application's non-volatile storage needs. Choose this part over the 24LC16B variant if operation below 2.5V is required, as the 24LC16B minimum voltage is 2.5V. Consider the 24FC16 if higher clock speeds up to 1 MHz are necessary across the full voltage range. Ensure the system design accommodates the 16-byte page write boundary constraints.

Memory IC Part Context

This device belongs to the 24XX16 family of serial EEPROMs manufactured by Microchip Technology. The family shares common architectural features including the I2C interface and memory organization but differs in voltage ranges and clock speed capabilities. The 'I' suffix denotes the Industrial temperature range, while 'MS' specifies the 8-lead MSOP surface mount package.

Memory IC Replacement Considerations

Direct substitutes include other packages of the same electrical specification such as 24AA16T-I/SN or 24AA16-E/MS. Cross-family replacements like 24LC16B require verifying that the system voltage does not drop below 2.5V.
