Intel has announced the extension of Intel Edison to a family of development boards. The key development is the use of a 22nm Intel Silvermont dual-core Atom SoC to replace the Quark SoC. Initially, Intel said the Edison development board was supposed to be based on the latter SoC.
The new dual-core Atom SoC, based on the same microarchitecture as the Atom Bay Trail, is rated to perform at 500MHz, with support for multi-threading. Intel says its decision to replace the Quark SoC with the more traditional Atom SoC is to “best meet a broad range of market needs." At the same time, the Atom SoC will bring hardware improvements that include an additional MCU and a 70-pin connector that supports over 30 I/O interfaces.
Intel also added the new Atom SoC-based Intel Edison will result in a larger footprint. In comparison, the Quark-based Edison development board was initially announced to be just the size of an SD storage card. Intel hasn’t abandoned the notion of releasing Quark-based development boards yet as the inclusion of Atom SoCs is just an extension of the Edison family.
