24LC16BH-E/P

Memory IC Overview

The Microchip Technology 24LC16BH-E/P is a 16-Kbit Electrically Erasable PROM organized as eight blocks of 256 x 8-bit memory. It operates on a single supply with a voltage range of 2.5V to 5.5V and supports I2C compatible two-wire serial interfaces at clock frequencies up to 400 kHz for VCC ≥ 2.5V. The device features low-power CMOS technology with maximum standby current of 5 μA in extended temperature ranges. It includes hardware write-protect capabilities, Schmitt trigger inputs, and output slope control. Available in multiple packages including PDIP, SOIC, MSOP, TSSOP, TDFN, and SOT-23, it meets industrial and extended temperature specifications.

Memory IC Feature Summary

• Hardware write-protect mechanism inhibits write operations to the upper half of the memory array when the WP pin is tied high.
• Integrated page write buffer allows storage of up to 16 bytes before initiating an internal self-timed erase/write cycle.
• Schmitt trigger inputs and noise filter circuits suppress bus spikes to ensure reliable data transmission on noisy environments.

Memory IC Applications

• Data logging systems requiring non-volatile storage for sensor readings or event timestamps
• Configuration storage for microcontroller-based embedded systems
• Calibration data retention in industrial instrumentation

Memory IC Procurement Notes

Verify that the ordering suffix 'E' corresponds to the Extended temperature range (-40°C to +125°C) and 'P' indicates the PDIP package type. Confirm the specific voltage operating range requirements align with the 2.5V minimum specification for this variant. Ensure compatibility with the I2C bus protocol timing characteristics defined in the datasheet AC characteristics table.

Memory IC Selection Notes

Select this component when a 16-Kbit EEPROM with hardware write protection is required. The 24LC16BH variant is suitable for applications needing operation down to 2.5V, distinguishing it from lower-voltage AA or higher-speed FC series members. Consider the PDIP package for through-hole mounting needs. Verify that the 400 kHz maximum clock frequency meets system bus speed requirements.

Memory IC Part Context

This part belongs to the 24XX16H family of 16-Kbit serial EEPROMs from Microchip Technology. It shares architectural similarities with the 24AA16H and 24FC16H but differs in voltage range and maximum clock speed. The 24LC16BH specifically targets applications requiring 2.5V to 5.5V operation with standard I2C speeds, offering a balance between power consumption and interface compatibility.

Memory IC Replacement Considerations

Direct substitutes within the same family include the 24AA16H (lower voltage support) and 24FC16H (higher speed). Cross-family replacements require verification of pinout compatibility, voltage levels, and I2C addressing protocols. Ensure any alternative device supports the same 16-Kbit organization and page write buffer size.
