Low-power CPU Module with Cortex-A5 Core
We optimized the design of the StampA5D3 for energy efficiency in every detail. The CortexA5 Core has been conceptualized by ARM© for lowest power usage in its performance class which has been consequently implemented by Atmel© as MPU in form of the SAMA5D36. And taskit continued along this guideline: From choice of power regulator to the usage of Low-power DDR memory. Complete support by Linux is for sure.
The power usage in power-down mode is only 5 mW. The running system only consumes 350 mW up to a maximum of 550 mW. With 533 MHz and up to 512 MB DDR as well as 1 GB Flash the StampA5D36 delivers enough performance for demanding applications in battery-powered or self-harvesting systems.
Modern ARM Cortex-A5
The new ARM Cortex-A5 core has been developed especially for low-power applications like mobile or self-harvesting devices. It provides the heart of the StampA5D36 computer module and stands out for it's small footprint and energy efficiency at high processing power. Being in the focus of chip development ARM driven systems provide a seamless future upgrade path.
Security, data integrity and secure communication poses a challenge for today's applications. The StampA5D36 has implemented various features to enable the development of hard- and software for encrypted communication and files, anti-cloning and software-piracy and base-board detection from boot to running application.
The taskit Vaultsec allows secure and unreadable storing of keys for public/private key encryption algorithms and SHA-256 hashes
The StampA5D36 CoM offers an own set of peripheral devices. These include but are not limited to standard interfaces like Ethernet 10/100/1000, USB, USART, JTAG, SSC, SPI, ADC, AC'97, TWI, digital I/O ports and parallel bus. Thanks to the direct access to 200 processor pins the user is fully flexible in employing the possibilities for application-specific features.
The StampA5D36 computer module features an integrated TFT/LCD controller with resolutions up to 2048 x 2048 pixels
Multiplexing is used on most pins, meaning that one pin can serve different functions. The number of usable I/O ports depends on the required combination of peripherals. Consult the datasheet for further information.
Linux OS and OpenEmbedded
The StampA5D36 cpu module comes pre-installed with the Linux operation system. Linux offers all the functions that one comes to expect from a modern operating system. Its multitasking, virtual memory management and dynamically loadable libraries make Linux ideal for many applications. Thanks to its open source concept the developer has full control of his system down to driver level. The OS core can always be adjusted to meet specific individual needs.
The powerful OpenEmbedded project allows developers to use precompiled packages and offers a broad choice of Linux applications for instant use. Furthermore it enables the developer to build his own, customized distribution.
Thanks to enhanced power management functions, well supported by Linux OS, a Stamp finds it's place in designs with restricted power requirements. Power consumption can be adjusted by using the power down or standby modes. If specific interfaces or peripheral devices are not needed, they can be individually powered off in order to reduce power consumption.
We offer a comprehensive starter kit for rapid evaluation and code development. The kit includes all the necessary hardware and software components for operating the Stamp of choice.
Upon request, taskit offers tailored solutions and carrier board design based on your individual needs and designs. Do you need minor modifications to already existing hardware or completely new products? We guide your project from prototype to serial production using our technical know-how and long years of experience – be it large-sale or small-scale.
