Features

Wireless Communication

• WLAN (IEEE 802.11 b,g)
• BlueTooth
• ZigBee
• ISM433, ISM866

Wired Communication

• CAN 2B (Controller Area Network) on 3 separate channels
• RS232 on 4 separate channels
• Differential SPI on 1 channel

Audio Communication

• Hermes-1 - by the help of an available SW - is able to "read" texts - Stored audio pattern speech generation
• Drive any hifi amplifier
• 8..12 bits output with 16 kHz sampling frequency
• Implementation of speech recognition is possible

Microcontroller and Memory>

• Built with Freesale's (Motorola) MPC5554 microcontroller - 132MIPS without cooling on 32 bit data
• MPC5554 has several low power modes to support power sensitive applications
• 8MB (70nsec) Flash memory for storage of software and static databases
• 2MB (10nsec) fast static RAM for storage of variables, dynamic databases
• 8 bit EEPROM for functional parameters and error log storage

Inputs and Outputs

• Digital Inputs - The ECU has four digital inputs, by which two-state sensing of 0..35V signals can be solved.
• Digital Outputs - The ECU has four digital outputs. These are not simple signal outputs, but these can drive maximum 2.2A loads each at supply voltage as high-side switches.
• Analog Inputs - The ECU has four analog inputs. By factory settings, voltages of 0..30V here will be converted to 12 integers by the MPC5554.
• Analog Outputs - The ECU has three analog outputs. These are 0..5V signal outputs

Power Supply

• Supports both 12V and 24V, negative mass battery systems, 8..32V voltage range
• Feeds external 5V units (e.g. antenna module, GPS, intelligent sensor, etc), maximum load 1A
