Octo SPI / HyperBus Interface is Designed for High Speed Serial Flash, RAM, and MCP

So far, if you needed high speed storage with low pin count in your MCU based board, you could use QSPI (Quad SPI) NOR flash, but earlier this month I wrote about STM32L4+ MCU family, which added two Octo SPI interfaces. I had never heard about Octo SPI previously. Those two interfaces can be used with single, dual, quad, or octal SPI compatible serial flash or RAM, and support a frequency of up to 86 MHz for Octal SPI memories in STM32L4+ MCU. STMicro OctoSPI interface also supports Cypress/Spansion Hyperbus mode to connect to HyperFlash or HyperRAM chip, or even HyperFlash + HyperRAM Multi-Chip packages (MCP), and variable or fixed external memory latency as defined by the Hyperbus protocol specification. The latter reveals Hyperbus supports performance up to 400 MB/s (provided the controller support 200 MHz), and relies on either 11 bus signals using 3.0V I/O (Single-ended clock CK), or […]

Renesas RZ/G Linux Platform features CIP Super Long-Term Support (SLTS) Linux kernel

In the consumer space, some devices never get updated, and you can consider yourself lucky if the manufacturer provides updates for several years, often just two as Linux LTS (Long Term Support) kernels had been supported that long so far. Google and the Linux Foundation realized that was not enough, so they recently announced 6-year LTS kernels at Linaro Connect SFO 2017, starting with Linux 4.4 released on January 2016, meaning it will keeping being maintained until January 2022 with security patchsets and bug fixes. But in the industrial/embedded space, they need even longer periods of support due to the longer equipment’s lifespan. I first heard about the Linux Foundation’s Civil Infrastructure Platform (CIP) project last year, when I covered the schedule for the Embedded Linux Conference Europe 2016. The project aims at providing a super long-term supported (STLS) open source “base layer” for industrial grade software. Several companies are […]

GR-LYCHEE Development Board to Combine Renesas RZ/A1LU Processor, ESP32 Module, and a VGA Camera

Japanese semiconductor vendors have mostly stayed away from the maker market, at least outside Japan, as most people would be hard-pressed to come up with a hobbyist development board powered by processor or micro-controller from Toshiba, Sony, Renesas or other Japanese companies, despite the three aforementioned names being in the top 20 semiconductors companies. I can only remember having written about Fujitsu F-Cue 96Boards, as well as Renesas GR-PEACH mbed board since I started this blog 7 years ago. Renesas seems to be the only company to have a real community behind with their “Gadget Renesas” pink-colored development boards, and the latest and seventh board is GR-LYCHEE powered by Renesas RZ/A1LU ARM Cortex-A9 processor, and equipped with a WiFi & Bluetooth module, and a camera. Renesas GR-LYCHEE board preliminary specifications: Micro-processor – Renesas RZ / A1LU (R7S721030VCFP 176-pin QFP) ARM Cortex-A9 Processor @ 384 MHz with 3MB on-chip SRAM Storage […]

Renesas SK-RZG1M Board Powered by R8A7743 Processor Gets Mainline Linux Support

Another board has gotten initial mainline Linux support recently, with Renesas SK-RZG1M starter kit board based on Renesas RZ/G1M dual core ARM Cortex A15 SoC with 2GB RAM, a SATA interface, HDMI, LVDS, AV Ethernet bridge, and more. Renesas SK-RZG1M starter kit board actually has the exact same features as Renesas R-Car M2 Porter board except for the processor: SoC – Renesas RZ/G1M (R8A7743) dual core ARM Cortex-A15 processor @ 1.5GHz with PowerVR SGX544MP2 3D GPU, Renesas 2D graphics processor System Memory – Dual channel 2GB DDR3 Storage – On-board 4 MB SPI, and 64 MB SPI, 1x SATA rev 3.1 connector, 1x SD card slot, and 1x micro SD card slot Video Output / Display I/F – HDMI (via ADV7511), and LVDS + touchscreen Analog Video In – ADV7180 video decoder with RCA jack, NTSC/PAL/SECAM autodetection Audio codec – AK4643EN with 3.5mm jacks for Line In and Line Out Connectivity […]

Renesas GR-PEACH mbed Board Features RZ/A1H Processor with 10MB On-chip Memory

Renesas RZ/A1 ARM Cortex A9 processors were unveiled in 2013, and one of the differentiating feature was the large amount of on-chip SRAM with up to 10MB for RZ/A1H model. The following year, Renesas’ RZ/A1 professional development kit, and some RZ/A1H modules were launched, and I’ve now just seen a tweet about Renesas GR-PEACH development board that is mbed compatible, feature Renesas RZ/A1H processor, and happens to be pink. There are actually two models based on the same PCB: GR-PEACH normal without header, and a “WiFi” connector, and GR-PEACH Full with female headers and an Ethernet port. Both basically share the same specifications: SoC – Renesas RZ/A1H ARM Cortex-A9 Core @ 400 MHz with 10MB on-chip RAM, NEON and FPU, and 128KB L2 cache Storage – 8MB FLASH + micro SD slot Connectivity – Normal: Optional BP3595 WiFi module; FULL: 1x 10/100M Ethernet(Microchip LAN8710A); Both: Xbee connector (unpopulated) USB – […]
