AH01 - SHA-256 Hardware Encryption

This xChip is a core encryption module which forms part of the Crypto module range, running a security algorithm based on SHA-256.

This xChip includes the ATECC508A from Atmel, which is a secure CryptoAuthentication device, which is equipped with an EEPROM array that can be used for storing of up to 16 key, certificates, consumption logging, security configurations and other types of secure data. Access to the various sections of memory can be restricted in several different ways and then the configuration can be locked permanently, to prevent changes.

The ATECC508A features a wide array of defense mechanisms specifically designed to prevent physical attacks on the device itself, or logical attacks on the data transmitted between the device and the system. Hardware restrictions on the ways in which keys are used or generated provide further defense against certain styles of attack.

Access to the device is made through a standard I2C interface at speeds of up to 1 Mb/s.

Product Highlights

  • Cryptographic co-processor with secure hardware-based key storage
  • SHA-256 hash algorithm with HMAC option
  • 256-bit key length
  • Storage for up to 16 keys
  • Guaranteed unique 72-bit serial number

CW02 - Wi-Fi & Bluetooth Core

An xCHIP core Wi-Fi & Bluetooth module. CW02 is based on the ESP32 which is a single 2.4 GHz Wi-Fi and Bluetooth combo chip designed with TSMC ultra-low-power 40 nm technology and an Xtensa® Dual-core 32-bit LX6 microprocessor.

Product highlights

  • Based on ESP-WROOM-32
  • 2.4Ghz Wifi and Bluetooth
  • 4 MB SPI Memory
  • Arduino, Mongoose OS, NodeMCU and Lua compatible
  • OTA capable through WiFi
  • Supports WPA Personal and Enterprise
  • RGB LED

IP01 - USB Programming Interface

This xCHIP is an interface module which is equipped to power and program other modules via a USB A connector. The USB A connection is required for programming the range of CPU Core xCHIPS over the USB-serial bridge provided by the FT232R.

Product Highlights

  • Based on FT232R From FTDI Limited
  • USB A connector for simple connectivity without the need of a cable
  • Programming interface for core ☒CHIPs such as CW01, CR01 and CC01
  • Equipped with switches that allow the user to switch serial and programming configurations
  • RGB LED for programming indicators

MD01 - Blank

This xCHIP is used as a placeholder for mechanical strength and xBUS redundancy. This blank xCHIP or dummy xCHIP also contains a QR code point to this store.

Product Highlights

  • Mechanical placeholder.
  • All signals and power are carried to create redundancy.

OC03 - Relay Out

OC03 is a low-voltage control relay module able to switch AC and DC loads.

The optically isolated relay is controlled by a PCA9554A IO expander, which provides an control interface to the switch. The PCA9554A has several selectable I2C addresses accessible via solder pads.

The TLP241A photorelay consist of a photo MOSFET optically coupled to an infrared light emitting diode which switches a AC or DC load. It provides an isolation voltage of 5000 Vrms, making it suitable for applications that require reinforced circuit insulation.

Product Highlights

  • Low Voltage AC/DC Control Relay
  • Load Voltage Range: 0 - 40 V
  • Load Current Rating: 2 A

SW01 - Advanced Weather Sensor

This weather sensor xCHIP is equipped with a weather sensor that is capable of measuring the temperature, humidity and atmospheric pressure.

The humidity sensor provides an extremely fast responce time for fast context awareness application and high overall accuracy over a wide temperature range.

The pressure sensor is an absolute barometric pressure sensor with extremely high accuracy and resolution.

The integrated temperature sensor has been optimized for lowest noise and highest resolution. Its output is used for temperature compensation of the pressure and humidity sensors and can also be used for estimation of the ambient temperature.
