MCU and DSP features combine in Flash hybrids
The 56F826 and 56F827 are Motorola's newest Flash-based hybrid controllers.
The expanded MSC711x family provides voice over IP (VoIP) equipment manufacturers with a fully scalable line of integrated DSPs to address a broad range of performance requirements.
The MSC7119 and MSC7118 increase the performance of the MSC711x family from 800 millions of multiply accumulates (MMACs) to 1200 MMACs at 300MHz while increasing on-chip memory from 192 to 256Kbyte.
To enable industry-standard network connectivity, the MSC7119 also includes the cost-effective 10/100 Ethernet, also available on the MSC7116 and MSC7113.

"Zultys is currently using Freescale's DSPs in the MX250 enterprise media exchange", said Mark Sigal, Vice President of Engineering at Zultys Technologies.
"Freescale's commitment to the scalable StarCore roadmap gives us the ability to address performance demands as our products evolve".
To enable higher-voice density system designs in the networking, VoIP and baseband markets, the MSC7119 and MSC7118 devices now enable 16-24 premium voice channels and 32-48 channels of G.711, allowing a single device to terminate a T1 or E1 connection.
The programmability of these DSPs also makes them attractive for the general-purpose market.
The MSC711x family is available in extended temperature ranges (-40 to +105C), a key feature for security, healthcare, industrial, instrumentation, imaging and other general-purpose signal processing applications.
Like all MSC711x family devices, the MSC7119 and MSC7118 integrate Freescale's innovative fieldBIST hardware diagnostic feature, which allows detection of and visibility into unlikely field failures for systems requiring remote fault isolation and detection capabilities.
The fieldBIST feature enables Freescale customers to test the structural health of an MSC711x DSP through a simple JTAG port without the need for expensive automatic test equipment (ATE).
This built-in self-test feature can be easily used by system software under customer-specific voltage and temperature conditions to report partial or complete device inoperability and identify errors in the memory, logic or PLL blocks.
Without even taking the DSP off the board, this in-field testing capability helps reduce error identification time from several days to a matter of minutes.
In related news, according to a recent DSP market bulletin from Forward Concepts, Freescale has moved up in the ranks to become the number-two supplier of DSPs with 59% growth in overall DSP shipments in 2004.
Forward Concepts projects that worldwide DSP shipments in 2005 will increase by approximately 10%, driven by the growth in the wireless market.
"As the industry's number-two DSP supplier, Freescale is in a strong position to support growing market demand for DSP-based solutions in 2005 through its continued commitment to delivering new DSP offerings based on StarCore technology", said Will Strauss, President and founder of Forward Concepts.
Freescale's DSP products based on StarCore technology are supported by a comprehensive ecosystem of development tools, operating systems and applications from third-party vendors.
This development suite provides the hardware, software and tools necessary to accelerate and streamline development of world-class products based on Freescale semiconductors.
Freescale also offers the SmartDSP OS, a royalty-free RTOS with source code as part of the tools offering and peripheral drivers for the MSC711x family of DSPs.
The MSC7116, MSC7115, MSC7113, MSC7112 and MSC7110 devices are all available in production quantities today.
Customer samples of the MSC7119 and MSC7118 are planned for Q2 2005, and production is planned for early Q3 2005.
Suggested retail pricing for the MSC7118 and MSC7119 is expected to range from US $33.00 to $35.00 in 10,000-unit volumes.
