DESCRIPTION

The ST1305B is a 192-bit EEPROM device with

associated security logic to control memory ac-

cess. The circuit includes counting capabilities

and thus is very well adapted to prepaid card ap-

plications.

The ST1305B is protected by hard-wired security

logic and special fuses. The memory is arranged

as a matrix of 24x8 cells, accessed in a serial bit-
