Reading of the whole memory is always possible. The memory can be written and erased byte by byte. Input data and the contents of the adressed byte are compared so that only bits are written which were not written before. Erasing is only possible byte-wise, even if only one bit is to be erased, but bits may be written individually. Each byte can be write/eraseprotected individually by setting a protect bit EEPROM ROM . The protect bit is only one time programmable and cannot be erased. SLE 4428 Additionally to the above functions this version has a PSC verification logic. All the memory, except for the PSC, can always be read.

SLE 4418

The chip contains an EEPROM organized 1024 x 8 bit offering the possibility of programmable write protection for each byte. Reading of the whole memory is always possible. The memory can be written and erased byte by byte. Input data and the contents of the adressed byte are compared so that only bits are written which were not written before. Erasing is only possible byte-wise, even if only one bit is to be erased, but bits may be written individually. Each byte can be write/eraseprotected individually by setting a protect bit EEPROM ROM . The protect bit is only one time programmable and cannot be erased.

SLE 4428

Additionally to the above functions this version has a PSC verification logic. All the memory, except for the PSC, can always be read. The memory can be written or erased only after PSC verification. The error counter can always be written. After eight successive incorrect entries the error counter will block any subsequent attempt at PSC verification and hence any possibility to write and erase.
2 Reset and Answer-to-Reset

Reset

When the operating voltage is applied, the chip goes into the power-on reset POR state. POR is terminated by reset. Reset is started by RST changing from “0” to “1” and finished by CLK going from “0” to This reset operation aborts any currently active command. After POR a read operation must be performed before any change of data is possible.

Answer to Reset ISO 7816

Answer to reset sets the address counter to “0” and the first data bit appears on the output. The contents of the following addresses can be read out with the following clock pulses. Answer to reset is executed by the following steps Fig. 2 :

RST goes from “0” to “1”, clock pulse is applied, RST changes back from “1” to
