Renesas Electronics has announced three new Target Boards for the RX65N, RX130 and RX231 32-bit Microcontroller (MCU) groups designed for home appliance, building and industrial automation applications. Each board has minimal features with an on-chip debugger, a mini USB port, the micro-controller, and through-hole pin headers providing access to all MCU signals. This design allows to access all MCU features while keeping the price below $30. Renesas Target Board specifications: MCU Renesas RX65N (R5F565NEDDFP) 32-bit RXv2 MCU @ 120 MHz with 2MB+32KB ROM, 640KB RAM Renesas RX130 (R5F51308ADFP) 32-bit MCU @ 32 MHz with 512KB+8KB ROM, 48 KB RAM Renesas RX231 (R5F52318ADFP) 32-bit RXv2 MCU @ 54 MHz with 512KB+8KB ROM, 64 KB RAM Expansion Unpopulated 12-pin Pmod connector 2x unpopulated 50-pin MCU headers Misc 2-pin Current measurement header Reset and user push buttons Power LED (Green), ACT LED (Green), 2x user LEDs (Green) 2-pin emulator reset header Power Supply […]
Renesas R-Car M3 Starter Kit is Designed for ADAS Applications
Most boards targeting the automotive market are impossible to purchase by individual, so last year I was pleasantly surprised when I discovered Renesas R-Car M2 Porter Linux automotive infotainment development board was available for sale on Digikey, and had good documentation on eLinux.org. The company has now introduced another automotive board, namely R-Car V3M starter kit, that’s not designed for infotainment, but instead for ADAS (Advanced Driver Assistance Systems) or even AD (Automated Driving) applications. Specifically, the board is supposed to “accelerate the development of New Car Assessment program (NCAP), front camera applications, surround view systems, and lidars” leveraging the company’s R-Car V3M image recognition SoC. Renesas R-Car V3M starter kit (V3MSK) specifications: SoC – Renesas R-Car V3M processor with two Cortex A53 64-bit cores @ up to 800 MHz, a dual lockstep Cortex-R7 32-bit core @ up to 800 MHz, IMP-X5-V3M image recognition engine System Memory – 448KB RAM on-chip; […]
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 […]
Renesas S5D9 IoT Fast Prototyping Board Combines Cortex M4F MCU, Sensors, and Ethernet
Renesas S5D9 IoT Fast Prototyping board is a board designed – as its name implies – for the Internet of Things, with the company’s Synergy S5D9 ARM Cortex-M4F micro-controller, various sensors, various I/Os including protected digital inputs and outputs, and Ethernet for network connectivity instead of a Bluetooth or/and WiFi module. Renesas S5D9 board specifications: MCU – Renesas Synergy S5D9 ARM Cortex M4F MCU @120MHz with 2MB flash and 640KB SDRAM Storage – 256Mbits (32MB) QSPI NOR flash Connectivity – 1x 10/100Mbps Ethernet (RJ45) USB – 1x micro USB Full Speed port Sensors Bosch BMC150 6-Axis sensor (digital compass) AMS ENS210 environmental sensor for temperature and humidity data TE Connectivity MS5637-02BA03 barometric pressure sensor Knowles SPU0414HR5H-SB amplified SiSonic microphone Expansion 1x PMOD connector (SPI) 2x Grove Connectors (UART, I2C, GPIO) 2x Protected Digital Input (5.1V to 24V) + 2x Buffered Digital Output (up to 1A) via Molex 12 position header […]
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 – […]
