Description
The AT91CAP7 semi-custom System on a Chip (SoC) provides Atmel’s ASIC customers a microcontroller platform for rapid integration of their own Intellectual Property (IP) in metal programmable cells. Fabrication time is greatly reduced since only the metal layers will remain to be generated on the silicon. In addition to 450K gates of metal programmable logic, the AT91CAP7 includes an ARM7TDMI core with a high-speed bus (AHB), on-chip ROM and SRAM, a full-featured system controller, and various general-purpose peripheral subsystems. It is implemented in a 130 nm CMOS 1.2V process and supports 3.3V I/O.
