Atmel has released 13 devices in three different product series in its 32-bit AVR UC3 product portfolio.

In addition to new devices in the existing UC3 L and UC3 A Series, a new UC3 D Series of MCUs is now available.

Atmel’s AVR UC3 product portfolio now includes:

- AVR UC3L: includes new memory options and adding USB functionality.
- AVR UC3D: targets entry-level 32-bit applications and includes hardware for capacitive touch support.
- AVR UC3A4: with high-speed USB and 128kbyte of SRAM. The devices also offer an optional 256-bit AES encryption decryption/encryption module.

The AVR UC3 L Series consumes down to 165µA/MHz in active mode, down to 600nA with RTC running, and down to 9nA in deep-sleep mode.

The UC3 L Series features the built-in capacitive touch peripheral, which supports capacitive touch buttons and sliders, and a new glue logic controller. Both can eliminate external components. 

Atmel has expanded the memory option of the currently available UC3L0 with 128kB and 256kB of Flash. These new devices also have 32kB of internal SRAM. The new UC3L4 devices are pin-compatible with the existing UC3L0 devices.

The UC3L4 adds full-speed USB device connectivity to the UC3L series. The new UC3L4 devices come in 64kB, 128KB and 256KB on-board Flash options, and offer up to 32kB of internal SRAM.

The new AVR UC3D MCU is an entry-level 32-bit series, well suited for product designs requiring low-power capacitive touch as well as other consumer and industrial applications.

The series offers devices containing a hardware QTouch capacitive touch interface, USB full-speed device, RTC with calendar, 10-bit ADC, USART, SPI, TWI, PWM and I2S .
