SmartACFL Modem
V.90/K56flex/V.34/V.32bis Modem Device Sets with Microcontroller (L2702),
Modem Data Pump (P9373), SmartDAA (20463), and Optional Voice Codec (20437)
for Low Power Applications
The Conexant SmartACFL V.90/K56flex Modem Device Set with SmartDAA
technology supports analog data up to 56 Kbps, analog fax to 14.4 Kbps,
telephone answering machine (TAM), V.80 synchronous access mode, on-
board DSVD, voice/speakerphone (optional), and cellular/GSM operation.
Serial, parallel, or PC Card host interface operation is supported depending on
the selected model (Table 1).
The modem supports ITU-T V.90/K56flex, V.34 and V.32bis data
modulations and is designed to operate with dial-up telephone lines in the U.S.
and worldwide. PC Card and parallel host interface models also support analog
cellular direct connect and GSM direct connect. Low profile, small TQFP
packages and low voltage operation with low power consumption make this
device set ideal for laptop, notebook, and palmtop applications using the
parallel host or serial DTE interface with the MCU, or the PC Card interface
with the MCUP.
The SmartACFL device set consists of a Microcontroller (MCU or MCUP) in a
128-pin TQFP, a Modem Data Pump (MDP) in a 100-pin TQFP, and a Line
Side Device (LSD) (SmartDAA device) in a 32-pin TQFP. The optional Voice
Codec (VC), in a 32-pin TQFP, supports voice/full-duplex speakerphone
(FDSP) operation with interfaces to a microphone and speaker and to a
telephone handset/headset. Figure 1 identifies the major hardware signal
interfaces. The MCUP supports two peripheral channels, one channel for the
modem and a second channel for an optional user-defined function
(Function 2).
Conexant's SmartDAA technology (patent pending) eliminates the need for a
costly line transformer, relays, and opto-isolators typically used in discrete DAA
(Data Access Arrangement) implementations. The SmartDAA architecture also
simplifies product implementation by eliminating the need for country-specific
components enabling worldwide homologation of a single modem board design
and a single bill of materials (BOM).
The SmartDAA system-powered DAA operates reliably without drawing power
from the line, unlike line-powered DAAs that operate poorly when line current is
insufficient due to long lines or poor line conditions. Enhanced features, such
as monitoring of local extension status without going off-hook, are also
supported.
Incorporating Conexant’s proprietary Digital Isolation Barrier (DIB) design
(patent pending) and other innovative DAA features, the SmartDAA
architecture simplifies application design, minimizes layout area, and reduces
component cost.

Description
General
The SmartACFL device set, comprised of separate
microcontroller (MCU), modem data pump (MDP),
and line side device (LSD) devices, provides the
processing core for a complete modem design. The
optional Voice Codec (VC) supports voice/full-duplex
speakerphone (FDSP) operation with interfaces to a
microphone and speaker and to a telephone
handset/headset (S models). The S model can also
be ordered with an RCDSVD Speech Codec
Processor (SCP) in a 100-pin PQFP to support
DSVD.
Modem operation, including dialing, call progress,
telephone line interface, telephone handset interface,
voice/speakerphone interface, and host interface
functions are supported and controlled through the
V.250, V.251, and V.253-compatible command set.
The modem hardware connects to the host via a
parallel, serial, or PC Card interface. The OEM adds
discrete components as required by the modem
model and the application to complete the system
(Table 1). These components may include a crystal
circuit, EEPROM, DIB components, telephone line
interface, optional voice/speakerphone interface, and
optional cellular/GSM interface.
Parallel interface operation, including cellular and
GSM support, is selected by PARIF input high. Serial
interface operation is selected by PARIF input low.
Cellular operation is selected by LINE/CELL input
low. GSM operation is selected by LINE/GSM input
low.

Hardware Description
SmartDAA technology (patent pending) eliminates
the need for a costly analog transformer, relays, and
opto-isolators that are typically used in discrete DAA
implementations. The programmable SmartDAA
architecture simplifies product implementation in
worldwide markets by eliminating the need for
country-specific components.
Microcontroller (MCU/MCUP)
The microcontroller is a Conexant 8-bit
microcomputer with pins to support serial
DTE/parallel host bus/PC Card, MDP, voice/TAM,
speakerphone, and RCDSVD SCP interface
operation. The operating voltage is +3.3V with +5V
tolerant inputs.
The MCUP incorporates a built-in PC Card interface
and CIS memory allowing the MCUP to directly
connect to the PC Card 68-pin socket without
requiring external PICA and CIS devices.
The MCU connects to the DTE/host via a V.24
(EIA/TIA-232-E) serial DTE interface or a parallel
host bus depending on installed firmware, whereas
the MCUP connects to a PC Card socket via built-in
PC Card interface. Unless otherwise stated,
references to general microcontroller functions
include both the MCUP and MCU.
The MCU performs the command processing and
host interface functions. The crystal frequency is
28.224 MHz. The MCU outputs a 28.224 MHz clock
to the MDP eliminating need for a separate MDP
crystal circuit.
The MCU connects to the MDP via dedicated lines
and the external bus. The external bus also connects
to OEM-supplied RAM (56 models), ROM/flash
ROM, and to the optional RCDSVD SCP.
The MCU connects to a serial EEPROM over a
dedicated serial interface.
Two independent functions are supported; the
modem function and an optional user-defined
Function 2. A Card Option Configuration Register
and a Configuration and Status Register for each
function allow independent configuration/control and
status reporting of the respective function.
The MCUP PC Card interface features include:
• PC Card interface logic and memory
− Internal 512-byte Card Information Structure
(CIS) provides the tuple information needed to
define the PC Card functionality.
− CIS Table is configurable from ROM/flash
memory (default) or from NVRAM (option)
− Address decode logic
• Modem Function
− Decoding for standard COM ports in
Overlapping I/O Address Mode
− Independent I/O Address Mode support
− Power-down mode control
− Digital speaker pass-through
− Supports two ring handling methods
