24CW I2C Serial EEPROMs

Microchip Technology 24CW I²C Serial EEPROMs are high-speed, highly-reliable, low-power devices in 16Kb, 32Kb, 64Kb, and 128Kb densities. The 24CW series is optimized for consumer and industrial applications, where reliable nonvolatile memory storage is essential. The 24CW series allows up to eight devices to share a common I²C bus and can operate across a broad voltage range (1.6V to 5.5V).
