Qualcomm MAPX
®
Series CSRA67xxx
Family of versatile, programmable audio
processing SoCs to help design a range of
products from entry-level to high-end.
Solution Highlights
The MAPX series of audio SoCs is extremely
versatile, supporting developers in designing
a wide variety of end products with minimal
incremental PCB design effort.
Family concept for device
compatibility
The MAPX family is a portfolio of integrated,
high-performance audio SoCs, embedding
three audio DSP cores, memory and a
multitude of digital and high quality analog
audio inputs and outputs.
The seven sub-families vary by the level of
embedded DSP, RAM and number of on-chip
analog and digital audio I/O interfaces. MAPX
SoCs are designed to be software compatible
with each other and pin-to-pin compatible in
the same package. This compatibility helps
manufactures to reduce their development
time, by using the same hardware and
software base when designing for the entire
range of end-products from entry-level to
high-end.
The USB interface supports digital audio file
playback and firmware updates from USB
storage devices and the integrated USB PHY is
designed to connect directly without external
active components.
With integrated high resolution audio PWM
modulator technology, MAPX processors are
designed to directly connect to up to 8 digital
class-D amplifiers, helping to remove the cost
of external PWM modulators. Alternatively,
the embedded high performance DACs are
designed to connect directly to analog (linear)
amplifiers helping to remove the cost of
external DACs.
This material is subject to change without notice.
87-CF479-1 Rev. B
The MAPX series of SoCs includes seven sub-families
that are available in one of two pin-compatible package
types. The entire family of MAPX SoCs are designed to be
software compatible, to help make it easier for developers
to switch between different devices to create unique
products with varying feature sets.

Extensive range of processing
technologies available
MAPX audio processors include a range of processing
technologies, including the royalty-free Qualcomm®
meloD™ audio processing suite, extensive lip-sync audio
delay and third party processing from Dolby, DTS and
others.
Maximum differentiation with
almost unlimited flexibility
Helping manufacturers to realize maximum differentiation
with the DSP code download option and Customizable
Modular Processing (CMP), MAPX supports custom
algorithms and filters by providing a C-language SDK.
Highly integrated audio SoCs
With 9MB embedded RAM and 3 DSP cores (432MHz), the
highest grade MAPX family SoC is engineered to provide
capability for HD audio decoding and up to 192kHz internal
processing chain. The device is also designed to integrate
high quality analog audio inputs and outputs, multiple
SPDIF and I2S interfaces, USB, I2C, SPI and UART.
Qualcomm Audio Solutions, MAPX, CSRA67xxx and Qualcomm meloD are products of Qualcomm Technologies Inc.
and/or its subsidiaries.
