16-bit realtime signal controllers

6 February 2008 DSP, Micros & Memory

Infineon Technologies has introduced a new family of 16-bit realtime signal controllers that feature fast interrupt response time and context switching specifically targeting industrial drive applications.

The new XE166 family of Real-Time Signal Controllers (RTSC) can control up to four individual motors simultaneously.

The XE166 family is based on the C166S V2 core. The high-performance RTSC products integrate a microcontroller (MCU) that combines the strengths of a 16-bit C166 core for the peripheral control with the computing power of a digital signal processor (DSP). Operating at 80 MHz and one cycle per instruction, all XE166 devices deliver 80 MIPS, which is twice the performance of the XC166 predecessor. Also, with a maximum of 768 KB, the XE166 flash capacity is three times more than the XC166. The software developed for existing C166 and XC166 controllers can be re-used with this new family.

The XE166 family integrates an embedded voltage regulator, various clock sources, brown-out detection and watchdog. The peripheral set includes up to four capture compare units to drive an electrical motor using either sinusoidal or space vector modulation algorithms. The XE166 products include two synchronisable analog-to-digital converters with 24 channels, 10-bit resolution and a conversion time of less than 1,2 microseconds. It also includes a wide range of interface options, such as a MultiCAN interface handling up to five CAN nodes and up to 128 message objects simultaneously. There is also a new level of flexibility which features up to six Universal Serial Interface channels to link to external peripherals via a UART, LIN, SPI, I²C or IIS interface.

To further improve safe application operations, Infineon has also implemented an error-correction coding (ECC) technology which finds and corrects single-bit errors and detects double-bit errors.
