DS2430A Description
This lot or product specific information can be accessed with minimal interface, for example a single port pin of a microcontroller. The DS2430A consists of a factory-lasered registration number that includes a unique 48-bit serial number, an 8-bit CRC, and an 8-bit Family Code (14h) plus 256 bits of user-programmable EEPROM and a 64-bit one-time programmable application register. The power to read and write the...
DS2430A Key Features
- 256-bit Electrically Erasable Programmable Read Only Memory (EEPROM) plus 64-bit one-time programmable application regis
- Unique, factory-lasered and tested 64-bit registration number (8-bit family code + 48-bit serial number + 8-bit CRC test
- Built-in multidrop controller ensures patibility 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 municates at up to 15.3kbits per second
- 8-bit family code specifies DS2430A munication 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
