32-bit MCUs feature low power, Ethernet, USB OTG

Chips provide 512 Kbytes of flash and use only 40 mA

Targeting networking, PC-centric embedded designs, and portable devices, the AT32UC3A0512 and AT32UC3A1512 32-bit flash microcontrollers are said to be the industry’s lowest-power ICs with Ethernet and USB On-the-Go. The three-stage pipeline Harvard architecture devices deliver 80 Dhrystone MIPS at 66 MHz and use only 40 mA at 3.3 V.

The chips have 512 Kbytes of flash and feature an embedded 10/100 Ethernet MAC, a full-speed (12-Mbit/s) USB 2.0 OTG interface, and a single-cycle 64-Kbyte SRAM with a direct interface to the CPU that bypasses the system bus. Both devices include a DMA controller, multilayer high-speed bus, a 10-bit A/D converter, two SPIs, an SSC, a two-wire I2 C-compatible interface, four UARTs, three general-purpose timers, seven PWMs, and a full set of supervisory functions.

The A1512 comes in a QFP100 package. The QFP144-packaged A512 has an external bus interface. (From $8.16 and $7.43 ea/10,000samples available now.)
