Flash MCUs suit low-power, PC-centric applications.

Press Release Summary:

Based on 32-bit AVR®32 UC core, UC3B Series is offered in 64- and 48-pin QFP/QFN packages with and without On-The-Go (OTG) capability, respectively. OTG capability changes USB device into USB host on-the-fly, enabling P2P communication between two USB devices. Both versions offer 12 Mbps USB 2.0, on-chip SRAM from 16-32 KB, and on-chip Flash from 64-256 KB. Able to deliver 72 Dhrystone MIPS @ 60 MHz, series consumes 23 mA @ 3.3 V and include true single-cycle MACs and DSP arithmetic.

Original Press Release:

Atmel Extends its AVR 32-bit MCU Family

64- and 48-pin Flash Microcontrollers with USB OTG

SAN JOSE, Calif., June 20 -- Atmel(R) Corporation (NASDAQ:ATML) introduced today a second family based on the AVR(R)32 UC core, its 32-bit Flash microcontroller with DSP extensions. Developed for low power PC-centric applications, the AVR32 UC3B Series of MCUs has Full-Speed (12 Mbps) USB 2.0 with On-The-Go (OTG) capability. On-chip SRAM ranges from 16K bytes to 32K bytes and on-chip Flash from 64K bytes to 256K bytes.

The AVR32 UC3B Series provides extended communication capability, excellent computational performance and low power consumption in a tiny form factor. The family targets applications such as appliance control, security systems, industrial control & automation and PC peripherals.

The new AVR32 UC3B devices deliver 72 Dhrystone MIPS (DMIPS) at 60 MHz, include true single-cycle MACs and DSP arithmetic and consume only 23 mA at 3.3V. With power consumption as low as 1 mW/DMIPS, UC3B Series MCUs outperform by a ratio of 3 any other available architectures offering similar features. The standby power consumption of UC3B Series is just 30 micro-Amps using a single 3.3V power supply and below 15 micro-Amps when the dual power supply (1.8V/3.3V) is used.

The AVR32 UC3B Full-Speed USB 2.0 interface allows communication with PCs through various USB classes such as Human Interface Device (HID) class for serial data communication or mass-storage class for larger bulk data transfers. The On-The-Go (OTG) capability changes a USB device into a USB host on-the-fly, enabling peer-to-peer communication between two USB devices. The UC3B Series also feature a 10-bit Analog-to-Digital converter (ADC), one serial programming interface (SPI), synchronous serial interface (SSC), I2C-compatible two-wire interface (TWI), three UARTs, three general purpose timers, seven pulse width modulators (PWM) and a full set of supervisory functions.

UC3B Series MCUs have DMA enabled peripherals with a seven-channel peripheral DMA controller, and a five-layer high speed bus matrix with point-to-point connections from all masters to all slaves at a maximum speed of 240M bytes/s at 60 MHz each.

Development Tools -- Atmel provides the AVR32 GNU C tool chain and FreeRTOS.org real-time kernel free of charge. Commercial software is also available including: IAR(R) (C compiler -- Embedded Workbench), ExpressLogic (Real-time Operating System -- ThreadX(R)) and Micrium (Real-time Operating System -- uCOS/II).

Atmel's AVR32 Studio and AVR JTAGICE mkII, provide the AVR32 UC3B Series with a multiplatform integrated development environment (IDE) already configured for the GNU tool chain, including support for advanced debugging sessions with data and code trace using the AVR32's Nano Trace or Nexus class 2+ interface. The ATEVK1101 kit is available for AVR32 UC3B Series evaluation.

Availability and Pricing -- The two first devices of the UC3B series are sampling now. The AT32UC3B0256, with OTG, is packaged in a 64-pin QFP/QFN and the AT32UC3B1256, without OTG capability, is packaged in a 48-pin QFP/QFN. The AT32UC3B0256 and AT32UC3B1256 in a QFP package are priced at US $4.96 and US $4.66 respectively in 10,000 quantities.
