The AVR AT32UC3C series 32-bit microcontrollers target sensor and control applications with a floating-point unit and 3.3- or 5-V operation. The ICs come with a 9-layer databus, 64 + 4 Kbytes of high-speed SRAM, 64 to 512 Kbytes of flash, DMA, 10/100 Ethernet, dual CAN ports, a USART, and a Full-Speed USB interface. An SDRAM interface is included in larger versions.
The processors also offer the Peripheral Event System, which allows inter-peripheral communication without CPU intervention. They have security technology that allows the flash memory to be partially programmed and locked, creating secure on-chip storage for private code and intellectual-property protection. The chips have one 4-channel 20-bit PWM controller. Package options range from QFN64 to TQFP144. (From $5.33 ea/10,000 samples available now.)
