24LC16BT-E/OT16KVAO

Memory IC Overview

The Microchip Technology 24LC16BT-E/OT16KVAO is a 16-Kbit Electrically Erasable PROM organized as eight blocks of 256 x 8-bit memory. It features a two-wire serial interface compatible with I²C protocols. The device operates on a single supply voltage ranging from 2.5V to 5.5V, supporting maximum clock frequencies of 400 kHz at VCC ≥ 2.5V and 100 kHz at lower voltages. It utilizes low-power CMOS technology with standby currents up to 5 μA and active read currents up to 1 mA. The component supports page write operations with a 16-byte buffer and self-timed erase/write cycles.

Memory IC Feature Summary

• Low-power CMOS technology enabling extended battery life in portable applications
• Hardware write-protect capability via the WP pin for data security
• Schmitt trigger inputs and noise filtering for reliable operation on noisy buses
• Self-timed erase and write cycles with automatic acknowledge polling support

Memory IC Applications

• Industrial control systems requiring non-volatile data storage
• Automotive electronics meeting AEC-Q100 qualification standards
• Consumer devices needing configuration parameter retention
• Smart meters and utility infrastructure monitoring equipment

Memory IC Procurement Notes

Verify the specific suffix '16KVAO' against official Microchip documentation to confirm it denotes factory programming or specific automotive grade variations not explicitly detailed in standard datasheets. Ensure the Extended temperature range (-40°C to +125°C) matches your environmental requirements. Confirm RoHS compliance status for your region's regulatory needs before finalizing procurement orders.

Memory IC Selection Notes

Select this component when an I²C-compatible EEPROM with automotive-grade reliability is required. The 24LC16B series offers higher speed compared to the 24AA16 variant but requires a minimum 2.5V supply. Consider the SOT-23-5 package for space-constrained designs. Verify that the system bus voltage levels are compatible with the 2.5V to 5.5V operating range to ensure proper logic level translation.

Memory IC Part Context

This part belongs to the 24XX16 family of serial EEPROMs, which also includes the 24AA16 and 24FC16 variants. While sharing similar architectural features, the 24LC16B specifically targets applications requiring 2.5V to 5.5V operation with 400 kHz I²C speeds. The 'E' suffix indicates the Extended temperature range, and 'OT' specifies the 5-lead SOT-23 surface-mount package type.

Memory IC Replacement Considerations

Direct replacements include other 24LC16B variants with different packages (e.g., SOIC, TSSOP) or temperature grades (Industrial 'I'). Cross-referencing with 24AA16 models is possible if voltage constraints allow, though clock speeds may differ. Always verify pinout compatibility and electrical characteristics before substituting.
