Synthesizable 1-Wire Bus Master

www.maxim-ic.com

FEATURES

C Memory maps into any standard byte-wide

data bus.

Customer ASIC

C Eliminates CPU “bit-banging” by internally

generating all 1-Wire^®timing and control

signals.

Internal

1-Wire

Bus

1-Wire

Master

C Generates interrupts to provide for more

efficient programming.

Data Bus

C Search ROM Accelerator relieves CPU from

any single bit operations on the 1-Wire Bus.

C Supports Overdrive mode and slave

interrupts.

Interrupt

C Capable of running off any system clock from

3.2MHz to 128MHz.

C Small size: all digital design, only 1500 gates.

C Available in both Verilog and VHDL.

C Applications include any circuit containing a

1-Wire communication bus.

DESCRIPTION

As more 1-Wire devices become available, more and more users have to deal with the demands of

generating 1-Wire signals to communicate to them. This usually requires “bit-banging” a port pin on a

microprocessor, and having the microprocessor perform the timing functions required for the 1-Wire

protocol. While 1-Wire transmission can be interrupted mid-byte, it cannot be interrupted during the

“low” time of a bit time slot; this means that a CPU will be idled for up to 60 microseconds for each bit

sent and at least 480 microseconds when generating a 1-Wire reset. The 1-Wire Master helps users handle

communication to 1-Wire devices in their system without tying up valuable CPU cycles. Integrated into a

user’s ASIC as a 1-Wire port, the core is available in both VHDL and Verilog code and uses very little

chip area (1492 gates plus 1 bond pad for the Verilog version).

This circuit is designed to be memory mapped into the user’s system and provides complete control of the

1-Wire bus through 8 bit commands. The host CPU loads commands, reads and writes data, and sets

interrupt control through five individual registers. All of the timing and control of the 1-Wire bus are

generated within. The host merely needs to load a command or data and then may go on about its

business. When bus activity has generated a response that the CPU needs to receive, the 1-Wire Master

sets a status bit and, if enabled, generates an interrupt to the CPU. In addition to write and read

simplification, the 1-Wire Master also provides a Search ROM Accelerator function relieving the CPU

from having to perform any single-bit operations on the 1-Wire bus.
