| Data Sheet AS2540 austriamicrosystems austriamicrosystems DATA SHEET (PRELIMINARY) Remote Controlled Single-Chip-Telephone AS2540 General Description The AS2540 is a CMOS integrated circuit that incorporates a speech circuit (line-adaptation, 2/4-wire conversion, separate Rx- and Tx-amplifiers for handset and modem), MF dialler, ring frequency detector, ring melody generator and a two wire serial interface. It shall act as an a/b-line-powered device in order to interface a main-powered CPU to the analogue telephone line. AS2540 can operate in a so-called mainpower mode and in a backup mode. During mainpower mode, a watchdog timer is running on AS2540, which has to be reset via the serial interface, which is connected to the CPU through opto-couplers. During backup mode (= The main-power failure or SW engine problem), AS2540 can operate as an independent basic MF dialler (digits 0-9*#) Key Features - Line Interface, Speech Circuit, MF Dialler and Tone Ringer on a 28 pin CMOS chip Programmable via 2-wire serial interface (UART 9600 baud, 8N1) Watch dog timer for Backup Mode Additional input for modem transmit path Additional output for modem receive path CMOS for high EMC immunity Low Noise (max. -72 dBm) Operating range from 15mA to 100mA (down to 5mA with reduced performance) Soft clipping for handset operation to avoid harsh distortion Line loss compensation selectable by pin option Real and complex impedance selectable by external components Side tone adaption selectable by external components Ring frequency discrimination 3-tone ring melody generator Applications - Web Telephones Answering Machines Fax Machines Base Station of Cordless Telephones Hospital Communication Units Package - 28 pin SOIC Dice-on-Foil Block Diagram Main Power Mode Line LS LI + 6dB Backup Mode Line LS LI + 6dB RI SB T -2d B + 2d B ROH ROT M1 M2 RI SB T -2dB + 2d B ROH ROT M1 M2 CS Mask CS Mask T IT CI DPn DT MFgenerator T IT CI AGND DPn DT MFg enerator AGND SMUT E S MASK S MAS K SMUTE SROH SROH SROT S DPn S DPn Dia l Dig it Dial Digit ST IT SROT ST IT RxD RxD DIALLER C1 C2 C3 R1 R2 MODE UART T xD C1 C2 C3 R1 R2 MODE VDD DIALLER UART T xD VDD RFD MO EHS MHS VS S OS C RFD MO EHS MHS VS S OSC Revision 3.1 Page 1 of 18 Data Sheet AS2540 austriamicrosystems Pin Description Pin # 15 Symbol RFD Function Ring Frequency Discrimination Schmitt trigger input for ring frequency discrimination.

CS Mask T IT CI DP n DT MFgenerator AGND S MAS K SMUT E SROH S DPn Dial Digit Ringing Mode AS2540 is supplied via the ring capacitor and external path, manual hook -switch and electronic hook-switch is open (MHS EHS = logical 0), the oscillator is running, a valid incoming ringing is signalled via the serial interface to the CPU. If the CPU does not reply the AS2540 switches into backup mode and sends a ring melody to the MO output. C1 C2 C3 R1 R2 MODE SROT ST IT RxD DIALLER UART T xD VDD RFD MO EHS MHS VS S OS C Backup Mode Manual hook-switch and/or electronic hook-switch is closed (MHS EHS = logical 1), AS2540 is supplied with line current, the oscillator is running, the keyscan is enabled and the handset path is switched on, signalling via the serial interface is possible. After AS2540 has started dialling in backup mode, he must not be interrupted any more in order to ensure consistent dialling. A mode transition BM -> MPM is only possible before AS2540 has started dialling digits independently. Start-up in backup mode As soon as AS2540 is supplied with line current, the external Vdd capacitor will be charged up via the LI and VDD pin and after the Vdd voltage has reached the operating level, the handset path of the speech circuit is switched on. This off-hook status is also signalled to the internal logic via the MHS or EHS pin in order to start the pinscan and subsequently set the country specific modes. Additionally a Start-up in ring mode When a ringing signal is applied to the line, Vdd of AS2540 is charged up via an external path. After Vdd has reached the operating voltage the oscillator starts and AS2540 discriminates the ring frequency. After a valid ring frequency is applied on the RFD pin, the logic sends a Main Power Mode Manual hook-switch and/or electronic hook-switch is closed, AS2540 is supplied with line current (MHS EHS = logical 1), the oscillator is running, the keyscan is disabled, AS2540 is controlled via the serial interface, handset path or monitor path or modem path is on, signalling via the serial interface is possible. Select Operation Mode Command Message DC conditions The normal operating mode is from 15mA to 100mA. An operating mode with reduced performance is from 5mA to 15mA. In the line hold range from 0mA to 5mA the device is in a power down mode and the voltage at LI is reduced to a maximum of 3.5V Revision 3.1 Page 4 of 18 Data Sheet AS2540 austriamicrosystems Receive path The gain of the LS --> ROH receive path is set to 2dB for ac-impedance 1000. The receive input is the differential signal of RI and STB. During DTMF dialling a MF comfort tone is applied to ROH which is -30dB relative to the line level. The soft clip circuit limits the output voltage at ROH to 1Vp. It prevents harsh distortion and acoustic shock. The gain of the LS --> ROT receive path is set to 0dB for ac-impedance 1000. The receive input is the differential signal of RI and STB. The soft clip circuit is not active for this output. The DC characteristic is determined by the voltage at LI pin and a 30 resistor between LI and LS pin. It can be calculated by the following equation: VLS = VLI + ILine * 30. The t.m. voltage at the LI pin is 4.5V. The calculation leads to the following DC resistances: 330 to 75 at line currents from 15mA to 100mA. 2/4 wire conversion AS2540 has a built-in dual Wheatstone bridge with one common ground. This provides a maximum of independence of AC impedance and side tone from each other. One can adapt side tone without changing the AC impedance. Modescan The DTMF-level on the line and the function of the line loss compensation can be selected with the connection of the MODE-pin to the keyboard matrix. The MODE-pin is scanned once after each OFF-Hook transition. PIN MODE PIN C1 PIN C2 PIN C3 A1=3.4/3.5 A2=-0.4 R1 AC impedance The ac impedance of AS2540 is set to t.m. 1000. With the external capacitor at CI pin it can be programmed complex. With a parallel impedance at the LS pin it can be programmed to 600.

The MHS is connected to the manual hook switch which is operated by the handset and the EHS is connected to an electronic hook switch which is operated by the CPU. Whenever the state of these inputs changes, AS2540 immediately sends - valid message is sent from the CPU. This makes sure that a non-operable CPU does not disable basic dialling functions. - Mode transition MPM BM A watchdog timer is started after Dialling Functions DTMF The DTMF generator provides 8 frequencies (in Hz): 1 1 697+1209 2 2 697+1336 3 3 697+1477 4 4 770+1209 5 5 770+1336 6 6 770+1477 7 7 852+1209 8 8 852+1336 9 9 852+1477 ** 941+1209 0 0 941+1336 # # 941+1477 Revision 3.1 Page 8 of 18 Data Sheet AS2540 austriamicrosystems The MF output levels are set to -4/-6dB which should allow efficient backup dialling under all line conditions. The TONE/PAUSE ratio is 90ms/90ms. The preemphasis between low group and high group frequencies is t.m. 2.6dB. Toner ringer melody The 3 basic melody frequencies are: F1=880Hz F2=1067Hz F3=1333Hz FLASH timing CPU can control the DPn pin and the MASK-mode of AS2540 via serial interface. The repetition rate is set to 4 which means that the sequence of F1, F2, F3, F1, F2, F3 is repeated 4 times within a second. Tone Ringer Ring frequency discrimination The ring frequency discrimination assures that only signals with a frequency between 13Hz and 70Hz are regarded as valid ring signals. When a valid ring signal is present for 102ms continuously, the ring melody generator is activated and remains active as long as a valid ring signal is present. Once the ring melody generator has started, the ring signal is continuously monitored and the ring melody generator is instantly turned off according to the momentary presence of a valid or invalid ring signal until next off-hook.
