DS2433-Z01 Datasheet, PDF (1/2 Pages) Dallas Semiconductor – 4K-Bit 1-Wire EEPROM

PRELIMINARY
DS2433-Z01
4K-Bit 1-Wire^TM EEPROM
www.dalsemi.com
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
16.3k bits per second
Overdrive mode boosts communication speed
to 142k bits 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 SOIC, 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

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 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.
