PIN DESCRIPTION
POWER
NAME
PIN
TYPE
DESCRIPTION
GND
1
I
System ground
VDD
16
I
Power supply input, 5 V ±10% (73K224BL). Bypass with 0.1
and 22 μF capacitors to GND.
VREF
31
O
An internally generated reference voltage. Bypass with
0.1 μF capacitor to ground.
ISET
28
I
Chip current reference. Sets bias current for op-amps. The
chip current is set by connecting this pin to VDD through a
2 M
resistor. ISET should be bypassed to GND with a
0.1 μF capacitor.
PARALLEL MICROPROCESSOR CONTROL INTERFACE MODE
ALE
13
I
ADDRESS LATCH ENABLE: The falling edge of ALE latches
the address on AD0-AD2 and the chip select on
CS
.
AD0-AD7
5-12
I/O
ADDRESS/DATA
multiplexed lines carry information to and from the internal
registers.
BUS:
These
bi-directional
tri-state
CS
23
I
CHIP SELECT: A low on this pin during the falling edge of
ALE allows a read cycle or a write cycle to occur. AD0-AD7
will not be driven and no registers will be written if
CS
(latched) is not active. The state of
CS
is latched on the
falling edge of ALE.
CLK
2
O
OUTPUT CLOCK: This pin is selectable under processor
control to be either the crystal frequency (for use as a
processor clock) or 16 times the data rate for use as a baud
rate clock in DPSK modes only. The pin defaults to the
crystal frequency on reset.
INT
20
O
INTERRUPT: This open drain output signal is used to inform
the processor that a detect flag has occurred. The processor
must then read the Detect Register to determine which detect
triggered the interrupt.
INT
will stay low until the processor
reads the detect register or does a full reset.
RD
15
I
READ: A low requests a read of the 73K224BL internal
registers. Data can not be output unless both
RD
and the
latched
CS
are active or low.
RESET
30
I
RESET: An active high signal on this pin will put the chip into
an inactive state. All Control Register bits (CR0, CR1, tone)
will be reset. The output of the CLK pin will be set to the
crystal frequency. An internal pull-down resistor permits
power-on-reset using a capacitor to VDD.
