Now available is a development kit for Atmel's low-cost, high-performance AT91 family of ARM9-based microcontrollers (MCUs). Features like atomic bit manipulation and deterministic execution augment the MCU architecture. The 30-MHz MCU contains a complement of peripherals typically found on high-end 8-bit MCUs. There's also a Fast USB device interface, plus a number of 25-Mbit/s serial interfaces. With the new kit, designers can get their hands on the chip. The AT91SAM7S32 Development Toolkit costs $295. It includes an IAR USB-based JTAG interface and IAR Embedded Workbench software, including a 20-state version of Visual State.
