 Cwad SBI is one of the new peripherals that we have on board the SDM32F7. The Cwad SBI peripheral has got two connections into the bus structure. We have the high speed bus connection for the data throughput coming off the memory chip. And you still have your peripheral registers and clocks to do all the configuration settings set up for the Cwad SBI. So it attaches to both of the clock domains. You can use it in any of the modes, single, dual or quad. You've got your clock source that goes out and you've got chip select control goes out in case you need to put the devices into low power mode and shut it down. Features, so again you can use each of the different modes. We do support dual quad SBI as well, so if you've got two identical chips you can wire them in on the board. Most of the time you'll be using memory mapped mode, so you'll be using it as read only so it'll be data or instructions that'll be coming out of there. If you are using a RAM chip then you can use the other two modes. We support all the different modes inside there. For data throughput we support single data rate and double data rate as well inside the device. So there's five foes on the reception and transmission, so someone was saying about the buffering of what's coming out. So the quad SBI has dedicated five foes built into that periphery as well. And there's the buffer store that's on the Axi bus when it's connected into that as well. Chip select for the low power control as well was in there. Some of the benefits, packages are a lot smaller for these quad SBI's. PCB design is a lot easier. You've not got 16 line tracks trailing across a PCB, which means your EMC issues are reduced a little. We've got all those signals bouncing up and down in the time. Lots of different memory sizes available. You can do RAM and flash. And there's lots of different third parties out there supplying these quad SBI devices now. So you've got quite a good selection to choose from. If we look at the performance, how we compare against the parallel devices. So standard parallel device at 99 a second access time, you get a throughput of about 22 megabytes per second on a standard parallel memory chip. If you take the maximum bus width on the serial ones, we get about 50 megabytes per second. So you're near double in the performance compared to a standard parallel memory chip with the quad SBI features. Next new peripheral, SPDIF. So it's the standard Sony digital interface. So it's an industry standard peripheral, mainly in the automotive consumer type world, docking ports now for iPods, anything where you need full audio. We support up to 192 kilohertz for the stereo streaming. We've got all the PLLs and clock structure so that you can get all the right frequencies that you need for doing all the audio, different selections, all the different symbol rates and that we've got. Low power timers, a new peripheral for the SDM32F family of devices. This peripheral was introduced about 18 months ago in the L0. If you're doing any type of application where you need to put the device into low power and you want to use a timer to wake it up. We now have the ability to run this timer asynchronously so it doesn't need the internal clock structure to be functioning inside the device. Which means that you can now clock it from an external clock source and it can be configured to receive the rising edges and then after so many pulses it wakes the device up again. If you're not using low power features, it is a general purpose timer. There's lots of different clock sources from the internal structure you can use and it's got lots of different modes like continuous one shot or PWM mode. So you can use it as a normal timer if you don't need it to be a low power timer for any part of your application. So it's designed to bring out of stop mode primarily. Sleet mode, you've still got your internal clock structure running anyway so it doesn't add much of a benefit. But stop mode is the lowest power mode that you can drop the device into and you can still wake it up. Plenty of interrupts, so as I said it is a general purpose timer. It's got all the various interrupt channels available to do what you need in your application. HDMI CEC, again another consumer based peripheral that we've added to the family. This was introduced on the F0 range of devices about five or six years ago. And it will send all the CEC commands from say a set up bot through the HDMI cable to usually a television is what you're normally connecting to. So again it manages all the protocols that you need for doing the HDMI CEC.
