During pulse dialing the speech circuit and other part of
Power On Reset
the device not operating is in a power down mode to save
current. The CS pin is pulled to VSS in order to turn the
external shunt transistor on to keep a low voltage drop at
the LS pin during make periods.
The on chip power on reset circuit monitors the supply
voltage (VDD ) during off-hook. When VDD rises above
approx. 1.2V, a power on reset occurs which clears the
RAM.
AC Impedance
DC Conditions
The ac impedance of the circuit is set by external
components. The impedance can be real or complex.
The ac impedance is determined as follows:
The normal operating range is from 13 mA to 100 mA.
Operating range with reduced performance is from 5 mA to
13 mA (parallel operation). In the operating range all
functions are operational.
ZAC = 33 · Z1
At line currents below 13 mA the AS253x provides an
additional slope below 4.5V in order to allow parallel
operation (see Figure 12).
The dc value of Z1 should be 30 Ω to maintain correct dc
performance.
Return loss and side tone cancellation can be determined
independent of each other.
The dc characteristic (excluding diode bridge) is
determined by the voltage at LI and the resistor R1 at line
currents above 13 mA as follows:
Speech Circuit
VLS = VLI + ILINE × R1
The speech circuit consists of a transmit and a receive
path with dual soft clipping, mute, line loss compensation
and sidetone cancellation.
The voltage at LI is 4.5V in the normal operating range.
Revision 8.8
Page 5 of 25
Data Sheet AS2533-36
austriamicrosystems
Transmit
Line Loss Compensation
The line loss compensation is a pin option. When it is
activated, the transmit and receive gains are decreased by
6 dB at line currents from 20 to 50 mA when LLC = AGND
and 45 to 75 mA when LLC = high (@ R1 = 30 Ω). The line
loss compensation is disabled when LLC = low (see Figure
6 and Figure 7).
The gain of the transmit path is 37 dB for 600 Ω line
termination from M1/M2 to LS (see test circuit Figure 9).
The microphone input is differential with an input
impedance of 20 kΩ.
The soft clip circuit limits the output voltage at LI to 2VPEAK
(see Figure 11). The attack time is 30 μs/6 dB and the
decay time is 20 ms/6 dB. When mute is active, during
dialing or after pressing the P/M key, the gain reduced by >
60 dB.
Dialing Functions
Valid Keys
The key scanning is enabled when HS/DPN is pulled high
and VDD is above VREF. A valid key is detected from the
keyboard by connecting the appropriate row to the column
(RON < 1 kΩ). This can be done using an n x m keyboard
matrix with single contacts. Four diodes are used to extend
the number of rows (see keyboard arrangement fig. 2). It is
also possible to connect a microcontroller to the rows and
columns (see application note AN3010).
Receive
The gain of the receive path is 3 dB for 600 Ω line
termination (test circuit Figure 9). The receive input the
differential signal of RI and STB. When mute is active
during dialing the gain is reduced by > 60 dB. During
DTMF dialing a MF comfort tone is applied to the receiver.
The comfort tone is the DTMF signal with level that is -30
dB relative to the line signal.
P/M and MT Key
The P/M key is used to enter the Program/Mute state.
Depressing the P/M key mutes the speech circuit and the
device is in program state. Repressing the P/M key
deactivates the mute and program state (toggle
function).The MT key works in similar way, but has no
program function.
The receive gain can be changed by pressing the volume
keys. The VOL key gives a +5.4 dB boost and has a toggle
function, i.e. repressing the key resets the gain to default.
As an alternative the +/– keys can be used. The + key
increases the gain by 8.1 dB in 3 steps and the – key
decreases the gain by 5.4 dB in 2 steps (total range 13.5
dB). On AS2533/35 the volume is reset to default by next
off-hook and on AS2534/36 the volume setting will remain
at last setting. A POR will always reset the volume to
default.
When program/mute is activated, the LED indication is
turned on (flashing: 80 ms 'on' and 1 sec 'off').
Dial Mode Selection
The default mode (LD or MF) can be selected by the mode
pin. When default LD mode is selected, a temporary
change to MF can be invoked by pressing T/P key (not
AS2535) or the * key (when mode pin = row 5, the MF tone
is generated with the first * key entry). The circuit will
revert to LD by repression the T/P key (not AS2535) or by
pressing the R (R1, R2 or R3) key or by next on-hook.
The soft clip circuit limits the voltage at the receive output
(RO) to 1V PEAK (see Figure 10). It prevents harsh
distortion and acoustic shock.
Sidetone
A good sidetone cancellation is achieved by using the
following equation:
When MF mode is selected by the mode pin, the circuit can
not be changed temporary to LD but will remain in MF
mode.
ZLine Z2
=
ZBAL Z1
The sidetone cancellation signal is applied to the STB
input.
Centrex Keys (not AS2535)
The alphanumeric keys accommodate easy use of centrex
services. The A, B, C and D keys are only valid in MF
mode (including temporary MF) and are not storable.
Pressing one of these keys will invoke the appropriate
MF tones to be transmitted.

The centrex keys are not stored in the RAM, and

Last Number Redial
Memory Keys (not AS2534)
LNR is a facility that allows resignalling of the last
manually dialed number without keying in all the digits
again. The LNR is repeatable after each off-hook.
The keys M1 to M12 are direct memory access keys and
the MR key (AS2533/36 only) is used for abbreviated
dialing.
The current content of the RAM is overwritten by new
entries.

A manually entered number is automatically stored in the
LNR RAM. The capacity of the RAM is 31 digits. If a
number greater than 31 digits is entered, the LNR facility
will be inhibited (until new entries < 32 digits) and further
entries will be buffered in FIFO.
10
In the on chip RAM, numbers can be stored. Each number
can contain up to 21 digits (including pauses).
During programming multiple pauses can be inserted by
pressing the PS (not AS2535) or the LNR key. Each pause
inserted within the first 5 entries will automatically be
terminated after 2 seconds whereas pauses inserted after
location 5 in a digit string will halt dialing and can be
terminated manually by pressing the PS (not AS2535) or
the LNR key. The halt function allows in-dialing to an
extension on a PABX.
Pauses can be inserted by pressing the PS key (not
AS2535).
Post dialed digits, i.e. digits manually entered after LNR
has been invoked, are not stored in RAM but buffered in
FIFO.
Repeat Dialing (not AS2535)
The last manually dialed number can be repeated without
going on-hook by pressing the RP key. If a called number
is engaged, pressing the RP key will break the line for 1.6
second (to get a new dial tone) and after a pause the
number will be repeated.
Example (45678–123 is stored in M1, where – is a
pause/wait and 123 the extension number):
off-hook, wait for dial tone
press M1 (45678 is dialed out)
await dial tone from called PABX
press PS or LNR (123 is dialed out)
The repeat function is enabled when prior to pressing the
RP key, a number has been dialed, and it can be invoked
an unlimited number of times until next on-hook. During the
1.6 second break the device is in power down mode to
save current.
Memory dialing is cascadable. However, the content of one
memory must be dialed out before a new can be invoked.
Sliding Cursor Procedure
To accommodate easy and uncomplicated redialing (LNR)
behind a PABX, a sliding cursor protocol is implemented. If
new entries match the previous RAM contents, pressing
the LNR key will dial out the remaining digits.
Recall Function
A recall (R1, R2 or R3 key) activation will invoke a flash
(timed loop break), however, the R1 flash is never
executed in LD mode. R2 and R3 will be executed
independent of the mode.
If there is an error in matching, the LNR will be inhibited
until next on-hook, and the RAM will contain the new
number.
If recall is the first entry in a digit string, it will be stored in
LNR RAM when digit(s) are entered after the recall.
Example (LNR content 912345, where 9 is access code):
off-hook, wait for PABX dial tone
If the recall key is depressed after a digit string has been
entered or dialed out, the recall will not be stored but
buffered in the FIFO together with subsequently entered
digit.
press 9 and wait for external dial tone
press LNR (12345 will be dialed out).
Tone Generator
If pressing the recall key is not followed by digit entries,
the LNR RAM remains intact.
The tone generator incorporates the DTMF tones, 3 basic
frequencies for the tone ringer and pacifier tones.
DTMF
After a recall a 270 ms pause will automatically be
The DTMF generator provides 8 frequencies, namely:

The procedure is ended by repressing the P/M key.
The default setting is digit 6, i.e. after a power on reset the
device will start up with repetition rate 4 and maximum
volume. If digit 0 is programmed, the tone ringer will be
turned off until next off-hook where it will turn back to the
last setting before 0. The programmed settings are stored
in the on chip RAM.

Repetition rate means that a sequence of 6 frequencies
is repeated 1, 4 or 10 times within 1 second.
The MF output level can be set with an external voltage
divider on pin MFL.
The sequence of the frequencies is controlled by the
sequence register as follows:

28 ms pauses between the tone bursts.
*typical MFL values for AGND = 1.5V
The preemphasis is 2.6 dB.
The MF tones are according to CEPT recommendations.
Tone Ringer (Melody/Volume)
The three basic frequencies of the melodies are:
F1 = 800 Hz, F2 = 1067 Hz, and F3 = 1333 Hz (± 5%).
Ring Frequency Discrimination
The ring frequency discriminator assures that only signals
with a frequency between 13Hz and 70 Hz are regarded as
valid ring signals. The time for recognizing a valid ring
signal is 1/f seconds, where 'f' is the ring frequency.
The repetition rate and the volume of the tone ringer
melodies can be programmed by pressing P/M and #
followed by a digit as follows:
Digit Repetition Rate
Volume
- 16 dB
- 7 dB
When a valid ring signal is present for 73 ms continuously,
the melody generator is activated and remains active as

Programming Procedures
Procedure Principles
Temporary MF
The procedures for utilizing the features of the AS253x are
optimized out of consideration for the human factor in
order to:
The procedure below assumes that the device is operated
in puls mode.

1. Go off-hook
not invoke any automatic functions which the user
doesn’t expect
2. Press [*] or [T/P] to switch to DTMF mode
3. Press [R] or [T/P] to switch back to PULS mode
4. Got to 2. to switch again to DTMF mode
-
-
protect the user from committing critical errors, e.g.
dialing wrong numbers, deleting stored numbers, etc.
be consistent, simple and usable.
Mode pin is connected to row 1, 2, 3, 4, or 5. When mode
pin = row 5, pressing the [*] key also transmits the tone by
MF selected. The [T/P] key (not AS2535) can be used
alternatively to the [*] key.
The following chapters describe the operating procedures
for the provided features. Pressing an invalid key or key
combination during programming will cause the device to
abort the program state. Pressing any key combination or
sequence which is not described or defined may cause the
device to enter a state or mode that does not comply with
the expectation of the user. In such cases, any undesired
state can be terminated at any time by going on-hook / off-
hook which will generate a functional reset.
Automatic Dialing
The following procedure describes the dialing procedure
and the internal sequences:
1. Go off-hook
2. Enter the number by pressing digit, [M1]-[M12], [LNR]
or [MR] + digit
Storing Numbers (not AS2534)
Up to 14 numbers, each with maximum 21 digits, can be
stored into the internal RAM.
3. The number is internally buffed in the FIFO
4. Tone- or Puls-Dialing starts
5. Wait for connection

Note 1: The values are valid during automatic dialing and
are minimum values during manual dialing, i.e. the
tones will continue as long as the key is depressed.
Note 2: The rise time is the time from 10% of final value till
the tone amplitude has reached 90 % of its final
value.
Note 5: This does not include the frequency deviation of the
ceramic resonator.
Note 6: During temporary MF mode.
Note 7: An invalid key entry in program mode will invoke a
tone sequence with 4 tone bursts of 40 ms and
pauses between bursts of 28 ms and abort the
program mode.
Note 3: Relative to high group.
Note 4: The FCI circuit is reset by POR and HS/DPN pulled
high (off-hook). After a reset the FCI circuit is in a
standby state. A positive edge on FCI will start a 73
ms timer and the frequency discrimination is
initiated. Whenever a period of the ring signal is
missing, the timer is reset. When a valid ring signal
is present for 73 ms, the melody generator is
started and is directly controlled by the ring signal.
This condition will remain until a new reset.
Note 8: Pauses inserted within the first 5 entries of a digit
string will be automatically terminated after 2
seconds. Pauses inserted after location 5 can only
be terminated manually by pressing the PS or LNR
key.
