Description
The SLx 24C32 device is a serial electrically erasable and programmable read only
memory (EEPROM), organized as 4096 × 8 bit. The data memory is divided into
128 pages. The 32 bytes of a page can be programmed simultaneously.
The device 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 operates at 5.0 V ± 10% with a maximum clock frequency of 400 kHz and at
2.7 ... 5.5 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.
