DESCRIPTION

The members of the ST1331/1333/1353 family are

principally designed for use in prepaid Phonecard

applications. Each is a 272-bit EEPROM device,

with associated security logic and special fuses to

control memory access. The memory is arranged

as a matrix of 34 x 8 cells, accessed in a serial bit-

wise fashion for reading and programming, and in
