DESCRIPTION

The DS2433-Z01 is identical to the standard DS2433 with the exception that the write cycle endurance specification is relaxed to 10,000 cycles as specified in WRITE CYCLE ENDURANCE SPECIFICATION Table 1. The device 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 (23h) plus 4096 bits of user-programmable EEPROM

FEATURES

4096 bits Electrically Erasable Programmable Read-Only Memory (EEPROM)

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

Memory partitioned into sixteen 256-bit pages for packetizing data

256-bit scratchpad with strict read/write protocols ensures integrity of data transfer

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

Overdrive mode boosts communication speed to 142kbits per second

8-bit family code specifies DS2433-Z01 communication requirements to reader

Presence detector acknowledges when reader first applies voltage

Low-cost PR-35, 8-pin SO, or solder bumped flip-chip package

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