Computer-on-module offers 1,850 MIPS and dual-gigabit Ethernet

Supplier News

KONTRON has released a computer-on-module (COM) based on the MPC8540 PowerQUICC III RISC processor from Freescale. Kontron's E Brain EB8540 COM offers pure, fanless computing with many I/O connection options at minimum power consumption. It is integrated as an add-on component into customised embedded systems.

EB8450 provides 1,850 MIPS (based on Dhrystone 2.1) at a clock speed of 800MHz, performance achieved by x86s only in the GHz range and only at a much higher power dissipation. It has a single Fast Ethernet and dual Gigabit Ethernet interfaces, up to six serial interfaces, two terminal interfaces (Rx/Tx) and four asynchronous 16550-compatible interfaces. A CAN bus is optional and it comes with a watchdog timer and real-time clock. It is suitable for real-time applications in industrial automation, transportation, medical technology and defence.

Individual expansions are achieved via the 32-bit, 33/66 PCI bus and/or the LPC bus. The two buses are connected to the baseboard via four standard SMD connectors. For security-critical applications, the module can be equipped with the MPC8541, which provides an additional security engine for IPSec, DES, 3DES and AES encryption. Apart from extensive interfaces, up to 512 MB of directly soldered, DDR SDRAM, up to 32 MB of Flash memory and 1 MB of battery-buffered SRAM, as well as E Prom for configuration and user data and an interface for CompactFlash memory cards, are mounted on the compact E 2 Brain EB8450 module, with dimensions of 75 mm × 115 mm. The physical slot for the CompactFlash memory media is placed on the baseboard. Debugging and onboard programming is done via the implemented JTAG/BDM interface. The power supply is designed as a single-source 3.3V supply. The standard version is designed for temperatures ranging from 0°C to 70°C. An optional version with an extended operating temperature range from 40°C to 85°C is also available.
