Raspberry Pi Compute Module 3 (CM3) and Compute Module 3 Lite (CM3L) Datasheet Released

Last week NEC announced they were going to use Raspberry Pi Compute 3 Module in some of their presentation and digital signage displays. This led to a longish discussion in the blog post, during which one commenter left a link to Raspberry Pi Compute Module 3 datasheet, so let’s have a look. There will actually be two version of the Broadcom BCM2837 based Compute Module with CM3 with a 4GB eMMC, and CM3 Lite (CM3L) without eMMC, but SD card signal are available to the baseboard. Apart from storage differences, both modules shared the same specifications: SoC – Broadcom BCM2837 quad core Cortex A53 processor @ 1.2 GHz with Videocore IV GPU System Memory – 1GB LPDDR2 Storage CM3 Lite – SD card signals through SO-DIMM connector CM3 – 4GB eMMC flash 200-pin edge connector with: 48x GPIO 2x I2C, 2x SPI, 2x UART 2x SD/SDIO, 1x NAND interface (SMI) […]

Hardkernel Releases Amlogic S905 Datasheet

When you design a board and/or write drivers for an SoC it helps a lot to get info about electrical characteristics, memory map, registers’ addresses and values to understand how the hardware works, especially for custom applications, but many silicon vendors only distribute such documents under NDA to their business customers, with exception from companies such as Freescale (now NXP), and Texas Instruments. Hardkernel, the company developing ODROID boards, is also trying to release as much documentation as possible for their board such as Amlogic S805 datasheet for ODROID-C1/C1+ boards, and the Korean company has now released Amlogic S905 processor datasheet as the processor is used in their ODROID-C2 board. Some of the information available in the datasheet include Memory map Power domain CPU and GPU sub-system Clock & Reset Unit System Boot General Purpose Input/Output (GPIO) Interrupt Controller Direct Memory Access Controller (DMAC) Timers Crypto Etc… ODROID-C2 was launched […]

Allwinner A64 Datasheet and User Manual Released

Allwinner has two 64-bit ARM processors in the works: Allwinner H64 and Allwinner A64. Both are quad core Cortex A53 processors with a Mali-400MP2 GPU, H.265 4K video playback with basically the same interfaces and peripherals, but H64 also supports H.264 at 4K resolutions, while A64 is limited to H.264 @ 1080p, and H64 adds a TS interface. The first good news is that two boards are in development: Orange Pi Plus 3 with Allwinner H64 Olimex A64-OLinuXino update with Allwinner A64 Engineering samples have already been produced for the first board, but that’s about all the information we have now, as Shenzhen Xunlong has not built its reputation by releasing documentation early. One the other hand, A64-OLinuXino schematics have nearly been completed, but we already know more details, as not only Olimex boards are open source hardware, but the company defies conventional wisdom by involving the community in the […]

Allwinner R8 Module Datasheet and Price. Is the $9 C.H.I.P Computer Selling at a Loss?

Allwinner R8 Cortex A8 processor, very similar to Allwinner A13, but optimized for IoT applications, was first unveiled via the $9 C.H.I.P computer crowdfunding campaign, but at the time we did not have that many technical details. However, Olimex had already made several Allwinner boards in the past, such as A20-OLinuXino-LIME, so they decided to investigate if they too could use Allwinner R8 processor, or rather Allwinner R8 Module (R8M) with R8 SoC, 4/8GB NAND Flash and 512 MB RAM. So they managed to get R8M datasheet, and got quoted $4.8 for Allwinner R8 and $16 for Allwinner R8M with 512 MB RAM and 8GB NAND Flash for 5,000 unit orders. Wait… If R8M module is $16, how can C.H.I.P sell it for $9? One difference is that C.H.I.P module only has 4GB NAND flash, but the module quoted to Olimex appears to come with 8GB flash, but it’s not […]

Amlogic S805 Datasheet Released

A datasheet release should not really be news, but not all companies are as open as Freescale, and possibly for fear of IP theft or patent trolls, most companies decide to keep datasheet, technical reference manuals, and other documentation confidential, and only release them under NDA, so it may take months before they come out, if ever. Thanks to Hardkernel and their ODROID-C1 board, Amlogic has allowed the release of Amlogic S805 datasheet (PDF 123 pages). The document is divided into two sections: Section I : System General Description Features Summary CPU and GPU subsystem Memory Map Power Domain Clock and Reset Unit System Boot General Purpose Input/Output (GPIO) Interrupt Controller Direct Memory Access (DMAC) Timer Real Time Clock Section II: Interfaces MMC/SD/SDIO Controller Inter-Integrated Circuit (I2C) Serial Peripheral Interface Communication Controller Serial Peripheral Interface Flash Controller (SPI) Universal Asynchronous Receiver and Transmitter (UART) Infrared Remote Universal Serial Bus (USB) […]
