Product details

8Kbit I²C EEPROM for parameter storage and calibration data

The Microchip AT24C08D-SSHM-B is a 8Kbit serial EEPROM organized as 1K x 8 bits, accessed through an I²C interface running at up to 1 MHz. It operates from a 1.7V to 3.6V supply, making it suitable for both 1.8V and 3.3V logic domains. The 4.5 µs access time and 5 ms write cycle time (word or page) define its read and write performance for non-volatile storage of configuration parameters, calibration constants, and small data logs.

Supply voltage and interface compatibility

The 1.7V to 3.6V supply range allows direct connection to 1.8V microcontrollers without a level shifter, while also working on standard 3.3V buses. The I²C interface at 1 MHz provides a 1 µs bit period, which is the standard fast-mode plus rate.

It is ROHS3 compliant.

Frequently asked questions

Where can I buy AT24C08D-SSHM-B?

AT24C08D-SSHM-B is available to order against an RFQ.

What is the clock frequency of AT24C08D-SSHM-B?

The I²C clock frequency is 1 MHz, which is the fast-mode plus rate.

What is the equivalent of AT24C08D-SSHM-B?

The through-hole equivalent is the AT24C08D-PUM, same 8Kbit I²C EEPROM in a DIP package. For surface mount with a faster 550 ns access time, the AT24C08C-XHM-B is a functional alternative, though verify the access time difference in your timing budget.
