PIN FUNCTIONS
V
GND. Digital ground.
AV
AGND. Analog ground.
V
age used by the high speed analog comparator to sample
the RX input signal.
RX (analog input). This is the RX IF receive signal from
the RF module, input to the analog comparator and FSK
demodulator. It is internally biased to the V
The IF signal from the RF module should be AC coupled
to the RX pin.
TX (analog output). This is the IF transmit signal to the RF
module, output from the FSK modulator and transmit 4-bit
D/A converter.
RXSW (output; active high or low programmable). This
pin reflects the programming of the demodulator turn-on
time.
TXSW (output; active high or low programmable). Con-
trol for the receive switch on the RF module. Active during
receive periods.
PAON (output; active high or low programmable). Con-
trol for the transmit switch on the RF module. Active during
transmit periods.
RFEON (output; active high or low programmable).
On/off control for the RF module. Active (on) during wake
periods. Inactive (off) during sleep periods on the handset.
RSSI (analog input). Receive signal strength indicator
from RF module, input to the RSSI 8-bit ADC.
PWLV (analog output). Power level control for RF module,
output from the transmit power 4-bit DAC.
SYLE (output). RF synthesizer load enable: latches new
frequency hopping control word of external RF synthesiz-
er. Programmable polarity.
ANT[1..0] (output). Control for optional antenna diversity
on the RF module.
MCLK (input). Master clock input.

(analog reference). This signal is the reference volt-
REF
DC voltage.
P R E L I M I N A R Y
CLKOUT (output). Clock output for external ADPCM pro-
cessor.
CODCLK (output). Clock output for external voice codec.
/RESETB (input, active low). Reset signal.
VXADD[2..0] (input). Address bus controlled by external
ADPCM processor. The Z87001 acts as peripheral of the
Z87010 ADPCM processor.
VXDATA[7..0](input/output). Read/write data bus con-
trolled by external Z87010 ADPCM processor.
VXSTRB (input). Data strobe signal for the VXDATA bus,
controlled by external Z87010.
VXRWB (input). Read/write control for the VXDATA bus,
controlled by external Z87010.
VXRDYB (output, active low). Ready control for the VX-
DATA bus. This signal is driven high (de-asserted) by the
Z87001 to insert wait states in the Z87010 ADPCM proces-
sor accesses.
TEST (input, active high). Main test mode control. Must be
set to GND.
HBSW (input with internal pull-up). Control
set/base configuration. Must be driven high or not connect-
ed for handset, low for base.
P0[15..0] (input/output). General-purpose I/O port. Direc-
tion is bit-programmable. Pins P0[3..0],when configured in
input mode, can also be individually programmed as wake-
up pins for the Z87001 (wake-up active low; signal internal-
ly debounced and synchronized to the bit clock).
P1[15..0] (input/output).General-purpose I/O port. Direc-
tion is bit-programmable. Pins P114 and P115, when con-
figured in input mode, also behave as individually
maskable interrupt pins for the core processor (positive
edge-triggered).
