DESCRIPTION The members of the ST1331D/33D 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 a byte-wise fashion for internal erasing. An on-chip address counter provides an internal address space of up to 512 bits. Table 1. Signal Names
