256-Bit 1-Wire EEPROM

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

15.3kbits 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 UCSP

surface mount package

? Reads and writes over a wide voltage range of

2.8V to 5.25V from -40°C to +85°C
