DS2430A_12 Datasheet, PDF (1/19 Pages) Maxim Integrated Products – 256-Bit 1-Wire EEPROM

19-5236; Rev 2/12
DS2430A
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
W _{compatibility with other MicroLAN products}
 EEPROM organized as one page of 32 bytes
E _{for random access}
N _{ Reduces control, address, data, and power to a}
single data pin
R  Directly connects to a single port pin of a
microprocessor and communicates at up to
O _{15.3kbits per second}
F _{ 8-bit family code specifies DS2430A}
communication requirements to reader
D _{ Presence detector acknowledges when reader}
E first applies voltage
 Low cost TO-92 or 6-pin TSOC and UCSP
D _{surface mount package}
N  Reads and writes over a wide voltage range of
2.8V to 5.25V from -40°C to +85°C
