FEATURES

PIN ASSIGNMENT

§ Universal, common-ground serial port to 1-

WireÔ line driver for MicroLAN applications

§ Works with all iButtons and MicroLAN-

compatible 1-Wire slave devices

§ Communicates at regular and Overdrive 1-

Wire speed and serial port data rates of 9600

(default), 19200, 57600 and 115200 bps

§ Supports 12V EPROM programming and stiff

5V pullup for crypto iButton, sensors and

EEPROM

§ Load sensor to terminate the stiff pullup as

the energy demand of the crypto iButton

drops

§ Self-calibrating time base with ± 5%

tolerance for serial and 1-Wire

to 5V based RS232 systems or directly to

UARTs

§ Programmable 1-Wire timing and driver

ORDERING INFORMATION

DS2480BS

8-pin SOIC

Note: The DS2480B will replace the DS2480

later in 1999. It is fully backward compatible to

software drivers that accept a 0 as well as a 1 for

bit 2 of the Reset-command response byte (see

page 7, Table 2)

§ Low cost 8-pin SOIC surface mount package

§ Operates over 4.5V to 5.5V from -40°C to

+85°C

DESCRIPTION

The DS2480B is a serial port to 1-Wire interface chip that supports regular and Overdrive speeds. It con-

nects directly to UARTs and 5V RS232 systems. Interfacing to RS232C (± 12V levels) requires a passive

clamping circuit and one 5V to ±12V level translator. Internal timers relieve the host of the burden of

generating the time-critical 1-Wire communication waveforms. In contrast to the DS9097(E) where a full

character must be sent by the host for each 1-Wire time slot, the DS2480B can translate each character
