DS2430A
Overview
The DS2430A 256-bit 1-Wire® EEPROM identifies and stores relevant information about the product to which it is associated. This lot or product specific information can be accessed with minimal i.
- 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
