Rainbow Electronics DS2433 - Manual

1 of 21 080902
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
16.3kbps
§ Overdrive mode boosts communication speed
to 142kps
§ 8-bit family code specifies DS2433
communication requirements to reader
§ Presence detector acknowledges when reader
first applies voltage
§ Low cost PR-35 or 8-pin SO surface mount
package
§ Reads and writes over a wide voltage range of
2.8V to 6.0V from -40°C to +85°C

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 interface, for
example a single port pin of a microcontroller. The DS2433 consists of a factory-lasered registration
