即插即用传感器DS2430AP+单总线存储器DS2430A+ 256-Bit 1-Wire EEPROM带电可擦写可编程

FEATURES

 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

DESCRIPTION

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 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 is derived entirely from the 1-Wire® communication line. Data is

transferred serially via the 1-Wire protocol, which requires only a single data lead and a ground return.

The 48-bit serial number that is factory-lasered into each DS2430A provides a guaranteed unique identity

that allows for absolute traceability. The TO-92 and TSOC packages provide a compact enclosure that

allows standard assembly equipment to handle the device easily for attachment to printed circuit boards

or wiring. Typical applications include storage of calibration constants, board identification, and product

revision status.
