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 bitwise fashion for reading and programming, and in Table 1.
