DS2430A
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
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 surface mount
package
§ Reads and writes over a wide voltage range of
2.8V to 6.0V from -40°C to +85°C
