The Microchip AT24C16D-MAHM-E is a 16 Kbit serial EEPROM organized as 2K x 8 bits, accessed through an I²C interface that runs at 1 MHz — the full fast-mode ceiling. The 5 ms page write cycle means the bus is tied up for that duration unless the host uses the acknowledge-polling method to detect completion.
There is no end-of-life notice, and it remains available for new designs through independent distribution.
The closest functional equivalent within the same family is the AT24CS08-MAHM-E, which is an 8 Kbit (1K x 8) I²C EEPROM in the same 8-UDFN package and supply range, but with half the density and a 550 ns access time. For a pin-compatible drop-in with the same 16 Kbit density, the through-hole AT24C16D-PUM shares the same core specs but uses a DIP package.
