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-
