M24C64M-FCU

The M24C64M-FCU is a 64-Kbit I2C-compatible EEPROM (Electrically Erasable PROgrammable Memory) organized as 8 K × 8 bits.

The Root part number 2 can be hooked on the same bus as the standard M24C64 in WLCSP 4 bump, thanks to specific device select code. See Section 4.5: Device addressing.

The M24C64M-FCU can operate with a supply voltage from 1.7 V to 5.5 V, over an ambient temperature range of -40 °C/+85 °C.

The M24C64M-FCU is delivered in a 4-ball WLCSP package.
