24LC16B/P

Memory IC Overview

The Microchip Technology 24LC16B/P is a 16 Kbit Electrically Erasable PROM organized as eight blocks of 256 x 8-bit memory. It features a two-wire I2C compatible serial interface with a maximum clock frequency of 400 kHz for VCC between 2.5V and 5.5V. The device operates within a supply voltage range of 2.5V to 5.5V and supports an industrial temperature range of -40°C to +85°C. Key electrical characteristics include a maximum active read current of 1 mA, a standby current of 5 µA at extended temperatures, and a typical access time of 900 ns. It utilizes a self-timed erase/write cycle with a page write buffer.

Memory IC Feature Summary

• Supports bidirectional data transfer via a standard two-wire serial bus protocol.
• Includes hardware write protection controlled by the WP pin state.
• Features Schmitt trigger inputs and output slope control for noise suppression.
• Provides over one million erase/write cycles with data retention exceeding 200 years.

Memory IC Applications

• Embedded systems requiring non-volatile data storage
• Industrial control devices needing parameter logging
• Consumer electronics utilizing low-power memory interfaces

Memory IC Procurement Notes

Verify that the specific ordering suffix matches the required package type, as the base part number covers multiple form factors. Confirm the temperature grade corresponds to the intended operating environment. Ensure compatibility with the system's I2C bus voltage levels before integration. Check for any recent product change notices regarding assembly sites or materials.

Memory IC Selection Notes

Select this component when a robust, industry-standard EEPROM with I2C connectivity is required. The PDIP-8 package is suitable for through-hole prototyping or applications where surface mount technology is not feasible. Consider the 400 kHz speed limit if higher bus frequencies are necessary, as other variants in the family may offer faster performance.

Memory IC Part Context

This component belongs to the 24XX16 family of serial EEPROMs manufactured by Microchip Technology. It shares architectural similarities with the 24AA16 and 24FC16 but differs in minimum operating voltage and clock speed specifications. The family is designed for general-purpose data storage in microcontroller-based systems.

Memory IC Replacement Considerations

Direct substitutes include other 24LC16B variants with different packages such as SOIC (SN), MSOP (MS), or DFN (MC). Cross-family replacements like the 24AA16 require verification of voltage level compatibility due to lower minimum operating thresholds.
