ST-E is currently laying out its strategy for the company going forward, having suffered a tremendous reduction in revenue as the mobile market has changed dramatically over the past couple of years. We've seen a bit of success from ST-E already with Sony's Xperia P and U announcements, both of which are powered by ST-E's U8500 SoC. Today ST-E is announcing a new 28nm SoC with integrated LTE baseband: the NovaThor L8540. 

The L8540 integrates a pair of ARM Cortex A9s running at up to 1.85GHz with a PowerVR SGX 544 GPU running at up to 500MHz. The L8540 features a dual-channel LPDDR2 memory interface. ST-E's new focus is on the mid-to-high end SoC market, but will not directly pursue the premium or entry level markets. Given the focus, you can expect to see more of these highly integrated SoCs which tend to resonate well in these mid-to-high end markets. 

The L8540 supports 1080p60 video encode and decode. The baseband supports LTE (FDD/TDD) at up to 100/50Mbps, HSPA+ 42/11Mbps and TD-SCDMA. ST-E claims the L8540 includes pre-integrated connectivity support for Bluetooth, GNSS, WLAN, WiFi Direct, FM and NFC. The pre-integrated connectivity appears similar to what Qualcomm offers at 28nm with its MSM8960, which should offer some tangible power efficiency advantages for data transfers over WiFi compared to discrete 4x-nm WiFi solutions.

ST-E expects a 10% improvement in power consumption as a result of the move to an integrated 28nm SoC compared to previous 4x-nm SoC + LTE baseband solutions. I'm still not sure what to expect in terms of smartphone battery life from the move to 28nm, but I have heard that it is significant.

The Novathor L8540 will begin sampling to customers in Q3 of this year.

    "" The baseband supports LTE (FDD/TFF)"
    Guessing that should be TDD not TFF.

    and btw the U8500 is also in the GALAXY S Advance and most likely in the Samsung Beam.

    Right now Samsung Advance and Beam + Sony Xperia U + Xperia P has been revealed.
    Earlier mid 2011, ST-Ericsson blurted out that it will soon try to provide Nokia with Novothor series of chipsets for future Windows phones....
    Looks like a market to grow from the relatively unknown position as of today.

    Though in the mid-end area. Looks like the first integrated chipsets NovaThor that can functionally match the Qualcomm MSMs (with integrated LTE/HSPA+ radios) in functionality.
    Surprised to see PowerVR substitute for Mali though...
    I do not see GPS as one of the features which is surprising. Perhaps, Anand forgot to pen it.

    Anand, any update on the "Rogue" series which will be ST-E's Cortex A15 implementation?

    Also first non AMD/non IBM fabbed chip in FD-SOI? Well, let us see if ST-E has a smooth implementation so that AMD can use ST-E as a fab for its server MPUs. They are a part of the IBM consortium and hence AMD can use them with minimal changes compared to shift to TSMC/UMC. ;-)

    GNSS covers GPS & GLONASS.
