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

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

16.3kbits per second

8-bit family code specifies DS2430A

communication requirements to reader

Presence detector acknowledges when reader

first applies voltage

Low cost TO-92 or 6-pin TSOC and Flip Chip

surface mount package

Reads and writes over a wide voltage range of

2.8V to 6.0V from -40°C to +85°C
