Terminal Functions
TERMINAL‡
I/O
DESCRIPTION
NAME
NO.
I/O
DESCRIPTION
CLKOUT/PO4(1)
2
O
Clock output / programmable output #4, bit 1. A 2.56-MHz clock signal is output on this terminal or the
device can be set so that it is bit 1 of PO4.
CS
33
I
Chip select (active low). This is the chip select input from the microcontroller.
DATAIN
35
I
Data input. Serial data from the microcontroller is input on this terminal.
DATAOUT
34
O
Data output. This is the serial data output to the microcontroller (3-state).
DCLK
36
I
Data clock. This is the serial microcontroller interface clock input.
HCLK/PO4(3)
4
O
TCM8010 interface clock / programmable output #4, bit 3. A clock signal to the TCM8010 or bit 3 of
programmable output 4 is output on this terminal.
HDATA/PO4(0)
1
I/O
TCM8010 interface data line/programmable output #4, bit 0. This terminal is used for data to and from
the TCM8010, or is bit 3 of programmable output 4.
HCS/PO4(2)
3
O
TCM8010 interface chip select output (active-low) / programmable output #4, bit 2. This terminal
selects the TCM8010, or is bit 2 of programmable output 4.
INTRPT
37
O
Interrupt output. This is the interrupt line to the microprocessor.
PIO1(0 – 7)
9–16
I/O
Programmable I/O port #1, bits 0 – 7. This 8-bit port can be configured as either inputs or outputs
(microcontroller port expansion).
PIO2(0 – 7)
18 – 25
I/O
Programmable I/O port #2, bits 0 – 7. This 8-bit port can be configured as either inputs or outputs
(microcontroller port expansion).
PIO3(0 – 3)
26 – 29
I/O
Programmable I/O port #3, bits 0 – 3. This 4-bit port can be configured as either inputs or outputs
(microcontroller port expansion).
RAEN/PO4(6)
43
O
Receive audio enable output/programmable output #4, bit 6. This terminal is used to enable the
receive audio section of the phone, or is bit 6 of programmable output 4 (open drain).
RCCBUSY/PO4(4)
32
O
RECC busy status/programmable output #4, bit 4. This terminal outputs the status result of the
majority vote of the three most recent busy/idle bits, or is bit 4 of programmable output 4.
RESET
40
I
Reset input, active low. A low applied to this terminal resets the TCM8002 and loads the default values
listed in the write map.
RFEN
30
O
RF enable. This terminal is used to enable the transmitter section of the phone (open drain).
RXIN
8
I
Baseband Manchester data input. Manchester-encoded data from control or voice channel is input
on this terminal.
SATIN
7
I
SAT input. Square-wave SAT data from the TCM8010 audio processor is input on this terminal.
SATOUT
5
O
Regenerated SAT output. Regenerated SAT data is output to the TCM8010 audio processor on this
terminal.
TAEN/PO4(7)
44
O
Transmit audio enable/programmable output #4, bit 7. The logic level on this terminal changes state
during RVC message or ST transmission, or is bit 7 of programmable output 4 (open drain).
TMZERO/PO4(5)
38
O
Timer zero/programmable output #4, bit 5. The logic level on this terminal changes state when the
counter/timer passes or reaches zero, or is bit 5 of programmable output 4.
TXOUT
6
O
Transmit data output. Encoded transmit data is output to the TMC8010 audio processor on this
terminal.
VDD
39
Positive supply voltage. Input is 3.3-V or 5-V.
VSS
17
Ground supply voltage.
WDOUT
31
O
Watchdog timer output. A logic-low pulse is output on this terminal when the watchdog timer times
out.
XTAL1
41
I
Crystal terminal 1/external clock source input. An external crystal is connected to this terminal for the
internal clock oscillator. An external clock signal can also be input on this terminal.
XTAL2
42
O
Crystal terminal 2. An external crystal is connected to this terminal for the internal clock oscillator.
† All inputs feature Schmitt triggers. All of the PIO terminals also feature optional 10-
µA pullups.
‡ ( ) = bit count when in the terminal column
