Maxim Integrated DS2430AP+T&R, 256bit EEPROM Memory Chip 6-Pin TSOC 1-Wire, Память

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
Applications
Accessory Identification and Control
IEEE 1451.4 Sensor TEDS
Medical Sensors
PCB Identification
