Power On Reset
te 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 motors he supply
voltage (VDD ) during offꢀhook. When 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 mto 10 mA.
Operating range with reduced performancfrom 5 mA to
13 mA (parallel operation). In the operatirange all
functions are operational.
ZAC = 33 Z1
At line currents below 13 mthe AS253x provides an
additional slope below 5V in order to allow parallel
operation (seFgur12).
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 chracteristic (excluding diode bridge) is
determined by he voltage at LI and the resistor R1 at line
curs 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.

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 hih
and VDD is above VREF. A valid key is detected from he
keyboard by connecting the appropriate row to thcolun
(RON < 1 kΩ). This can be done using an n x m keyoard
matrix with single contacts. Four diodeare used to extend
the number of rows (see keyboard aangment fig. 2). It is
also possible to connect a microcntrolr to the rows and
columns (see application notN300).
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 ad MT Key
The P/M key is used to enter the Program/Mute state.
Depressing the key mutes the speech circuit and the
device is in prgram ate. Repressing the P/M key

progfuction.
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 eu
As an alternative the +/– keys can be used. Th+ key
increases the gain by 8.1 dB in 3 steps and e – ky
decreases the gain by 5.4 dB in 2 steps otal rnge 13.5
dB). On AS2533/35 the volume is rsto dfault by next
offꢀhook and on AS2534/36 the volumetting 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 onꢀhook.
The soft clip circuit limits the voltage at threceive output
(RO) to 1V
(see Figure 10). It prevents hsh

distortion and acoustic shock.
Sidetone
A good sidetone cancellation s 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.

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.

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 offꢀhook.
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 insertby
pressing the PS (not AS2535) or the LR key. Each pause
inserted within the first 5 entries wiautoatically be
terminated after 2 seconds whereas pases inserted after
lation 5 in a digit string wilalt diling and can be
termited manually by pressing he PS (not AS2535) or
the LR key. The halt fnctioallows inꢀdialing 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 onꢀhook by pressing the RP key. If a called number
is engaged, pressing the RP key will break the linfor 6
second (to get a new dial tone) and after a pause the
number will be repeated.
Example (4568–12istored in M1, where – is a
pause/waind 1the extension number):
offꢀhook, wait or dial tone
pres1 (45678 is dialed out)
aait dial tone from called PABX
presPS or LNR (123 is dialed out)
The repeat function is enabled when rior tpressing the
RP key, a number has been dialed, acan be invoked
an unlimited number of times until neonꢀhook. During
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 ill voke a flash
(timed loop break), however, the R1 flasnever
executed in LD mode. R2 and Rwill be executed
independent of the mode.
If there is an error in matching, the LNR will be inhibited
until next onꢀhook, and the RAM will contain the new
number.
If recall is the first enin a igit string, it will be stored in
LNR RAM when diit(s) ae entered after the recall.
Example (LNR content 912345, where 9 is access code):
offꢀhook, wait for PABX dial tone
If the recall key is epressed after a digit string has been
entered odialeout, the recall will not be stored but
buffin the FIFO together with subsequently entered
dig
press 9 and wait for external dial tone
press LNR (12345 will be dialed out).
Tone Generator
Ipressing 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 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 offꢀhook where it will turn back to the
last setting before 0. The programmed settings are stored

Tone Ringer (Melody/Volume)
The three basic frequencies of the melodies are:
F1 = 800 Hz, F2 = 1067 Hz, and F3 = 1333 z (± 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 he ringer
melodies can be programmed by pressin/M and #
followed by a digit as follows:
Digit Repetition Rate
Volume
ꢀ 16 dB

When a valid ring signal is present for 73 ms continuously,
the melody generator is activated and remains active as

Complex Impedance
(270 W + 750 W // 150 nF)
Only the components
necessary for
presenting the
complete functions of
the AS253x are
included.
The external components
might change to comply
with various national PTT
regulations and to interface
to different transducers.
Since the AS253x is a
component and not a complete
system, it can not be approved
as a stand alone part by the
standard bodies. Hence, full
conformance to any standards
is depending on the application
in which the AS253x is being
used, and therefore, approvals
by the standard bodies are the
responsibility of the customer
and austriamicrosystems AG will
not have tested the product to
meet specific standards.

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, , or 5. When mode
pin = row 5, pressing the [*] key alstranmits the tone by
MF selected. The [T/P] key (not A2535can 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 onꢀhook / offꢀ
hook which will generate a functional reset.
Automatic Dialing
The following predure describes the dialing procedure
and the internl seqces:
1. Goffꢀhok
2. ter he number by pressing digit, [M1]ꢀ[M12], [LNR]
or [MR] + digit
Storing Numbers (not AS2534)
Up to 14 numbers, each with maximum 2digitscan be
stored into the internal RAM.
The number is internally buffed in the FIFO
4. Toneꢀ or PulsꢀDialing starts
5. Wait for connection
1. Press [P/M] to enter program mode
2. Enter location (MR + digit1; or M1 to M12)
3. Enter number ꢀ entries (0ꢀ9, *, #, PS or LNR, R, 2,

Note 1: The values are valid during autoc dialing and
are minimum values durg maual dialing, i.e. the
tones will continue along as the key is depressed.
Note 2: The rise time is thtime rom 10% of final value till
the tone amplitde hareached 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 o high group.
Note 4: ThFCI ciruit is reset by POR and HS/DPN pulled
hih (ofhook). After a reset the FCI circuit is in a
tandby state. A positive edge on FCI will start a 73
mtimer 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.
