Description

The SLx 24C164 device is a serial electrically erasable and programmable read only memory (EEPROM), organized as 2048 X 8 bit. The data memory is divided into 128 pages. The 16 bytes of a page can be programmed simultaneously.

The device SLx 24C164 conforms to the specification of the 2-wire serial I²C-Bus. Three chip select pins allow the addressing of 8 devices on the I²C-Bus. Low voltage design permits operation down to 2.7 V with low active and standby currents. All devices have a minimum endurance of 106 erase/write cycles.

The device SLx 24C164 operates at 5.0 V ± 10% with a maximum clock frequency of 400 kHz and at 2.7 ... 4.5 V with a maximum clock frequency of 100 kHz. The device is available as 5 V type (V_CC = 4.5 . 5.5 V) with two temperature ranges for industrial and automotive applications and as 3 V type (V_CC = 2.7 . 5.5 V) for industrial applications. The EEPROMs are mounted in eight-pin DIP and DSO packages or are also supplied as chips.
