CONTIGUOUS ADDRESSING
ACROSS MULTIPLE DEVICES
Chip Select bits A2, A1 and A0 can be used to expand
the contiguous address space by adding up to eight
24XXs on the same bus. Software can use the three
address bits of the control byte as the three Most
Significant bits of the address byte. For example, in the
24XX32 devices, software can use A0 of the
control
byte
as address bit A12; A1 as address bit A13; and A2
as address bit A14 (Table 5-1). It is not possible to
sequentially read across device boundaries.

* Up to two 24XX128 or 24XX256 devices in the MSOP package can be added for up to 256 kb or 512 kb of address
space, respectively. Bits A0 and A1 must be set to ‘
0
’.
