MIPI I3C Sensor Interface is a Faster, Better, Backward Compatible Update to I2C Protocol

I2C (Inter-Integrated Circuit) is one of the most commonly used serial bus for interfacing sensors and other chips, and use two signals (Clock and Data) to control up to 128 chips thanks to its 7-bi address scheme [Update: That’s the theory, as in practice it’s limited to a dozen devices max. due to capacitive load, see comments]. After announcing it was working of a new I3C standard in 2014, the MIPI Alliance has now formally introduced the MIPI I3C (Improved Inter Integrated Circuit) Standardized Sensor Interface, a backward compatible update to I2C with lower power consumption, and higher bitrate allowing it to be used for applications typically relying on SPI too. I3C offers four data transfer modes that, on maximum base clock of 12.5MHz, provide a raw bitrate of 12.5 Mbps in the baseline SDR default mode, and 25, 27.5 and 39.5 Mbps, respectively in the HDR modes. After excluding […]

HummingBoard Edge SBC Gets an mSATA/M.2 Connector, an eMMC Flash, and More I/Os

SolidRun launched its HummingBoard family last year with a board with a form factor similar to the Raspberry Pi, but instead of using a Broadcom processor, the boards were based on Freescale i.MX6 single, dual or quad core processors. The company has recently introduce a higher end board with Hummingboard Edge that adds an M.2 connector, eMMC flash, 7 to 36V DC power input, more camera interfaces, a DSI interface, and more GPIOs. The following comparison table shows the differences between the new Hummingboard Edge, and the older HummingBoard Pro and Base boards. HummingBoard-Edge HummingBoard-Pro HummingBoard-Base uSOM model i.MX6 based Solo to Quad Core uSOM Memory Up to 4GB DDR3 Storage uSD, eMMC, M.2/mSATA uSD, mSATA uSD Connectivity 1x RJ45*, 4x USB 2.0, mPCIE with SIM card holder 1x RJ-45*, 2x USB 2.0 Hosts, 2x USB 2.0 header, mPCIE half-size 1x RJ-45*, 2x USB 2.0 Hosts Media HDMI-out, LVDS, analog […]

MIPI Introduces SoundWire Audio Interface for Mobile Devices

MIPI (Mobile Industry Processor Interface) Alliance is a non-profit corporation that establishes standards for hardware and software interfaces in mobile devices. MIPI is better known for its MIPI DSI (Display Serial Interface) and CSI (Camera Serial Interface), but as you can see from the diagram below, they’ve been busy publishing a lot more interface specifications. The latest being MIPI SoundWire, a new audio interface for amplifiers, microphones and audio codecs used in smartphones, tablets, mobile PCs and other devices. The consortium only released a “MIPI SoundWire Specification Brief” so there aren’t that many details. SoundWire is not the first audio interface from MIPI, with SLIMbus having been first introduced in 2007, and later updated in 2013 with SLIMBus 1.1. SLIMbus must not have been that widely used, as only Intrinsyc OPEN-Q 8084 Development Kit appears to feature the interface among all the board listed on CNX Software. Nevertheless SLIMBus and […]
