Rainbow Electronics DS2406 - Manual

1 of 31 110501
FEATURES
§ Open drain PIO pins are controlled and their
logic level can be determined over 1-Wire ®
bus for closed-loop control
§ Replaces and is fully compatible with
DS2407 but no user-programmable power-on
settings and no Hidden Mode
§ PIO channel A sink capability of 50mA at
0.4V with soft turn-on; channel B 8mA at
0.4V
§ Maximum operating voltage of 13V at
PIO-A, 6.5V at PIO-B
§ 1024 bits user-programmable OTP EPROM
§ User-programmable status memory to
control the device
§ Multiple DS2406’s can be identified on a
common 1-Wire bus and be turned on or off
independently of other devices on the bus
§ Unique, factory-lasered and tested 64-bit
registration number (8-bit family code +
48-bit serial number + 8-bit CRC tester)
assures error-free selection and absolute
identity because no two parts are alike
§ On-chip CRC16 generator allows detection
of data transfer errors
§ Built-in multidrop controller ensures
compatibility with other 1-Wire net products
§ Reduces control, address, data, programming
and power to a single data pin
§ Directly connects to a single port pin of a
microprocessor and communicates at up to
16.3 kbits/s
§ Supports Conditional Search with user-
selectable condition
§ V
cc
bondout for optional external supply to
the device (TSOC package only)
§ 1-Wire communication operates over a wide
voltage range of 2.8V to 6.0V from -40°C to
+85°C
§ Low cost TO-92 or 6-pin TSOC surface
