24AA16H-I/MS

Memory IC Overview

The Microchip Technology 24AA16H-I/MS is a 16-Kbit Electrically Erasable PROM organized as eight blocks of 256 x 8-bit memory. It operates on a single supply ranging from 1.7V to 5.5V with a maximum clock frequency of 400 kHz at voltages above 2.5V, and 100 kHz below 2.5V. The device features an access time of 900 ns, a page write buffer for up to 16 bytes, and a maximum write cycle time of 5 ms. It supports Industrial temperature range (-40°C to +85°C) and is housed in an 8-lead MSOP package.

Memory IC Feature Summary

• Hardware write-protect capability for the upper half of the memory array via the WP pin
• Low-power CMOS technology ensuring minimal active and standby current consumption
• Integrated Schmitt trigger inputs and output slope control for enhanced noise suppression and signal integrity

Memory IC Applications

• Data logging applications requiring non-volatile storage
• Configuration parameter storage in embedded systems
• Calibration data retention in industrial instrumentation

Memory IC Procurement Notes

Verify that the specific ordering suffix matches the required package type and temperature grade. Confirm that the voltage requirements align with the system's power supply rails, particularly noting the frequency limitations at lower voltages. Ensure compliance with RoHS standards if applicable to the manufacturing process.

Memory IC Selection Notes

Select this component when a 16-Kbit capacity is required within a compact surface-mount footprint. Consider the hardware write-protect feature if partial memory protection is necessary without software overhead. Evaluate the low standby current benefits for battery-operated designs where power conservation is critical.

Memory IC Part Context

This part belongs to the 24XX16H family of serial EEPROMs, which includes variants like the 24LC16BH and 24FC16H. These devices share similar architectural features but differ in operating voltage ranges and maximum clock frequencies. The 'I' designation indicates the Industrial temperature rating, while 'MS' specifies the 8-lead MSOP package.

Memory IC Replacement Considerations

Direct substitutes include other members of the 24XX16H family such as the 24LC16H or 24FC16H, provided voltage and speed requirements are met. Cross-referencing with other manufacturers' I2C-compatible EEPROMs requires careful verification of pinouts and electrical characteristics.
