ZWERG332

Single Board Computer with MC68332, 16MHz

... Simply gigantic!

Logo

The ZWERG332 is quasi the big brother of the other boards of the ZWERG series. First the ZWERG11A, next ZWERG11plus and then ZWERG332, the top-ZWERG, regarding performance and speed (although of the same small size of only 51mm x 54mm). In contrast to the other members of the ZWERG family, it is not based on the MC68HC11, but on the controller MC68332 from Motorola. The high clock frequency (16.67MHz, 8 times the HC11 clock) and the 32Bit CPU make it a powerful embedded controller. The MC68332 also has an improved timer system compared to the HC11. It consists of a separate TPU (Time Processing Unit), allowing different functions to be executed simultaneously on 16 channels (e.g. Input Capture, Output Compare, PWM...).

The ZWERG332 has 512KB battery-bufferd SRAM and 512KB on-board-programmable FLASH.

The serial interface, with transmission rates up to 500kBit/s, can be connected to various IF-Modules, allowing different standards (e.g. RS232 or RS485).

In addition the MC68332 provides a SPI (Serial Peripheral Interface) for fast serial I/O devices like the on-board A/D converter TLC2543 from Texas instruments.

The RTC is also connected to the SPI.

Moreover, the ZWERG332 is equipped with a BDM (Background-Debugging-Mode) connector. BDM not only allows debugging programs, but also direct communication with the CPU, downloading and programming the FLASH.
