Atmel provides FPGA logic that decodes and encodes the bus traffic that flows between the FPGA and the AT91CAP7E microcontroller. The logic blocks inside the FPGA are connected to the AT91CAP7E via the AHB master and slave channels.

The AT91CAP7E is a standard microcontroller with an FPGA interface that makes the FPGA look and work like it is on the internal bus on the MCU. Customers who are considering the AT91CAP7 customizable MCU for their designs, frequently need a two-chip, no-NRE, FPGA-plus ARM7 solution as they are gaining market momentum. The AT91CAP7E provides such a solution and offers an engineering-free migration path to a lower cost, lower power customizable MCU when volume justifies it. The AT91CAP7E is available in a 225 LFBGA package (13 x 13 x 1.4mm).

AT91CAP7 Customizable MCUs

Atmel’s AT91CAP7 customizable MCU is an ARM7-based microcontroller with a metal-programmable (MP) block with 450K gates or the equivalent of 56K FPGA logic cells (LC). Any functionality that has been implemented in an FPGA may be migrated directly to a CAP7 device with no special EDA tools or customer-side engineering. Standard FPGA software tools are all that is necessary to implement functions such as LCD controllers, DSP algorithms (e.g. GPS correlators, FFTs, FIR filters), and proprietary customer IP. A AT91CAP7 implementation delivers as much as 8X better performance, consumes 98% less static power, and costs about 30% less than the FPGA-plus-MCU implementation. The AT91CAP7 is available in multiple packages.
