Single Board Computer with MC68332, 16MHz

SCOTTY332 has been redesigned. The new version (SCOTTY332 - 05/2007) has only one 16Bit wide RAM instead of two 8Bit wide RAMs. Battery-buffering is also possible. The layout changes do neither affect dimensions nor the position of connectors. The two EPROM-sockets were replaced by two FLASH-Memories (29F040). Software is not affected.

Version 05/2007 optionally runs with a 25MHz clock. This reqires the following lines in the application's initialization sequence:

   INTERN.qsm.sccr0 = 40;        /* 19200 baud */
   INTERN.sim.syncr = 0xd700;    /* 25.17 MHz */

The price for SCOTTY332 is not changed, thus reducing the real costs, as the two FLASH-Memories are included for free.

The modern Scot

LogoThe success of the SCOTTY08 directly forced us to design a new, more powerful member of the SCOTTY family. The SCOTTY332 uses a MC68332 CPU (CPU32) with a 16Bit data bus (only 8Bit on SCOTTY08). Together with the faster CPU32 this yields an increase in performance of about factor six. But SCOTTY332 can also operate in 8Bit mode with a single EPROM or FLASH, and still three times the performance compared to the original SCOTTY.

Dimensions and connectors are compatible to SCOTTY08.

In addition SCOTTY332 is equipped with the CAN controller SJA1000 (Full CAN according to CAN2.0B standard) and the 10 channel 12Bit A/D converter TLC2543.
