detailed description
block size
This device generates read instructions for the EEPROM. Read transactions consist of read opcode, address
and data cycles. Data cycles are comprised of 2-byte DATA. After power up resets, this device reads the
programmable block size value from address zero in the EEPROM. Data [15:13] carries the block size
information for logical device 0. Data [11–9] carries the block size information for the logical device 1 (see Table
1).

EEPROM signal description
This device interfaces to SGS-Thomson’s compatible EEPROM 2-Kbit ST93C56 or 4-Kbit ST93C66. After
completion of the configuration sequence, it allows an optional on-board controller to access the EEPROM.
During and after reset, TL16PNP100A gains access to the EEPROM by asserting EEPROM low, informing the
optional on-board controller that it is accessing the EEPROM. After the configuration is complete, the device
leaves the configuration mode, is activated, and is in the wait-for-key state. The EEPROM signal is then
released and pulled high, SIO is released and pulled down, and SCS and SCLK are placed in the
high-impedance state and pulled down.
NOTE
When the device enters the configuration mode again and leaves the wait-for-key state, it gains
direct access to the EEPROM after the EEPROM signal is released. The wake command generates
a read transaction from address 0×1, which is the beginning of the resource data of the card.
When the EEPROM signal is released, the interface of the EEPROM is idle. The TL16PNP100A
drives the EEPROM signal low when the device enters the configuration mode again.
