Key Applications
Atmel's Diopsis®940HF is designed for data-intensive applications requiring the combination of a high
performance microcontroller unit and floating point DSP capablities. Its parallel architecture incorporates
a VLIW floating point processor, Magic DSP™, delivering up to 10 floating point operations per cycle and an
ARM926EJ-S™ARM®Thumb®RISC CPU. The ARM926EJ-S supports the Jazelle®technology for Java®
acceleration. A rich set of peripherals and internal memory provide a highly flexible and integrated system
solution. The system-on-chip embeds distributed DMA to support data moves related to the on chip peripherals
and to the processing performed by mAgic. The availability of on-chip memory for Magic and ARM reduces the
data traffic on the external bus and allows an effective usage of the available processing and I/O resources.

platform to consumer market


1. Full Peripheral Set.
2. Some peripherals are not accessible by the user in this low-cost version. Reduced Peripheral Set = Full Peripheral Set - 2 CANs - 3 SSCs - 1 SPI - 1 TWI
- 2 USARTs. Consequently the related PIO lines can be used only as SW controlled PIO lines (not linked to any peripherals).
