FEATURES
 256-bit Electrically Erasable Programmable
Read Only Memory (EEPROM) plus 64-bit
one-time programmable application register
 Unique, factory-lasered and tested 64-bit
registration number (8-bit family code + 48-bit
serial number + 8-bit CRC tester) assures
absolute identity because no two parts are alike
 Built-in multidrop controller ensures
compatibility with other MicroLAN products
 EEPROM organized as one page of 32 bytes
for random access
256-Bit 1-Wire EEPROM

 Reduces control, address, data, and power to a
single data pin
 Directly connects to a single port pin of a
microprocessor and communicates at up to
15.3kbits per second
FOR 1 2 3
 8-bit family code specifies DS2430A
communication requirements to reader
D  Presence detector acknowledges when reader
E first applies voltage
D  Low cost TO-92 or 6-pin TSOC and UCSP
surface mount package
N  Reads and writes over a wide voltage range of
E 2.8V to 5.25V from -40°C to +85°C
