DESCRIPTION

The ST1305 is a 192-bit EEPROM device with associat-

ed security logic to control memory access. The circuit

includes counting capabilities and thus is very well

adapted to prepaid card applications.

The ST1305 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-wise fashion for

reading and programming, and in a byte-wise fashion

for internal erasing.

The device recognises three commands issued via the

RST and CLK pins (as described in the full data sheet):

– RESET: to reset the internal address register to 00d

– READ: to increment the internal address register,

– PROG: to program the bit at the current address.
