UNISOC, formerly Spreadtrum Semiconductor, has announced its first mobile application processor with an integrated 5G modem. Dubbed the T7520, the SoC also happens to be one of the world’s first chips to be made using TSMC’s 6 nm process technology, which uses extreme ultraviolet lithography (EUVL) for several layers.

The UNISOC T7520 application processor packs four high-performance Arm Cortex-A76 cores, four energy-efficient Arm Cortex-A55 cores, as well as an Arm Mali-G57 GPU with a display engine that supports multiple screens with a 4K resolution and HDR10+. Furthermore, the SoC integrates a new NPU that is said to offer a 50% higher TOPS-per-Watt rate than the company’s previous-generation NPU. In addition, the chip features a four-core ISP that supports up to 100 MP sensors and multi-camera processing capability. Finally, the AP also features the company’s latest Secure Element processor that supports ‘most of crypto algorithms’ and can handle compute-intensive security scenarios, such as encrypted video calls.

One of the key features of the UNISOC T7520 is of course its integrated 2G/3G/4G/5G-supporting modem, which supports 5G NR TDD+FDD carrier aggregation, as well as uplink and downlink decoupling for enhanced coverage. All told, the T7520's modem is designed to offer peak uplink speed of 3.25 Gbps.

The high level of integration of the T7520 SoC is designed to enable smartphone manufacturers to build more reasonably priced 5G handsets, which will inevitably increase their popularity and adoption of the technology. Meanwhile, usage of TSMC’s 6 nm fabrication technology (known as N6) should allow UNISOC to make the AP for less than compared to non-EUV fabrication processes.

UNISOC did not announce when it plans to start shipments of its T7520 application processor, though it is reasonable to expect it to become available this year.

    Ah, ok, got it mixed up then!

    That's not entirely correct. To clarify, Spreadtrum never ever used Intel's modem. It was always to replace ARM with x86 core on Spreadtrum's existing portfolio. And of course since it's Intel's x86 core, it has to be manufactured by Intel's fab.

    Now that's out of the way, no, not nothing at all came out of that collaboration, SC9853I-IA did make it to the market in very small amount, perhaps just a few thousands in circulation.

    18% extra density offered, but 7+ offered 20% with four instead of five EUV layers and tighter design rules. Strange arrangements.

    Not really. N6/N7P are the true nodelet/half-node successor to N7. N7+ is just a black sheep that nobody used except for the one single chip Kirin 990 5G.

    AMD's 7+nm wouldn't be N7+ either. It would be derived from either N7P or N6.

    I guess the first smartphone chipset on 6nm technology. Looks really good for the smartphones.
