EOC
PARALLEL INTERFACE
The parallel interface of the AD7829-1 is eight bits wide. Figure 23
shows a timing diagram illustrating the operational sequence of
the AD7829-1 parallel interface. The multiplexer address is latched
into the AD7829-1 on the falling edge of the RD input. The on-
chip track/hold goes into hold mode on the falling edge of
CONVST. A conversion is also initiated at this point. When the
conversion is complete, the end of conversion line (EOC) pulses
low to indicate that new data is available in the output register
of the AD7829-1. The EOC pulse stays logic low for a maximum
time of 110 ns.
However, the
pulse can be reset high by a rising edge of
RD
EOC
. This
line can be used to drive an edge-triggered
interrupt of a microprocessor. CS
RD
and
going low accesses
the 8-bit conversion result. It is possible to tie CS permanently
low and use only RD to access the data. In systems where the
part is interfaced to a gate array or ASIC, this EOC pulse can be
applied to the CS
RD
and
inputs to latch data out of the
AD7829-1 and into the gate array or ASIC. This means that the
gate array or ASIC does not need any conversion status
recognition logic, and it also eliminates the logic required in the
gate array or ASIC to generate the read signal for the AD7829-1.
