24LC16B-I/P

Memory IC Overview

The Microchip Technology 24LC16B-I/P is a 16-Kbit (2K x 8) serial Electrically Erasable PROM housed in an 8-lead PDIP package. It operates on a single supply voltage ranging from 2.5V to 5.5V with a maximum clock frequency of 400 kHz. The device features a two-wire I²C compatible interface, Schmitt trigger inputs for noise suppression, and hardware write protection via the WP pin. It supports page writes up to 16 bytes with a maximum cycle time of 5 ms. Designed for industrial applications, it functions within a temperature range of -40°C to +85°C.

Memory IC Feature Summary

• Two-wire serial interface compatible with I²C protocol
• Hardware write protection capability via dedicated pin
• Schmitt trigger inputs for enhanced noise suppression
• Self-timed erase/write cycles with automatic termination

Memory IC Applications

• Industrial control systems requiring non-volatile data storage
• Embedded devices needing configuration parameter retention
• Low-power consumer electronics utilizing I²C communication

Memory IC Procurement Notes

Verify that the ordering suffix 'I' corresponds to the Industrial temperature grade (-40°C to +85°C). Confirm the 'P' suffix indicates the 8-lead PDIP through-hole package. Ensure the specific variant matches the required 2.5V minimum operating voltage specification for the 24LC16B series.

Memory IC Selection Notes

Select this component when a through-hole PDIP package is required for prototyping or specific board layouts. Choose the 24LC16B over the 24AA16 if the system operates exclusively at voltages of 2.5V or higher, as the 24LC16B does not support operation below 2.5V. Verify that the 400 kHz maximum clock speed meets the system bus requirements.

Memory IC Part Context

This part belongs to the 24XX16 family of 16-Kbit serial EEPROMs manufactured by Microchip Technology. The family includes variants like the 24AA16 and 24FC16, which differ primarily in operating voltage ranges and maximum clock frequencies. The 24LC16B specifically targets standard 3.3V and 5V logic systems.

Memory IC Replacement Considerations

Direct functional substitutes include other 24LC16B variants with different packages such as 24LC16B/SN (SOIC) or 24LC16B/MS (MSOP), provided the physical footprint allows for adaptation.
