Atmel has announced the availability of its new 32-bit AT32UC3L AVR 32 microcontroller with picoPower technology and embedded capacitive touch controller peripheral.
According to Atmel, the AT32UC3L is a low power 32-bit MCU with less than 0.48 mW/MHz in active mode and uses picoPower technology that enables it to operate on less than 1.5 uA with the 32 KHz real time clock active, and below 100 nA with all oscillators stopped.
The 1.6V technology device has an Embedded Capacitive Touch peripheral that supports touch buttons and sliders. QTouch technology will provide the touch system with a high signal to noise ratio which reportedly improves the system’s design margin, increases EMC performance and raises ESD tolerance.
The new AT32UC3L includes a flash security technology FlashVault, which allows the on-chip flash to be partially programmed and locked. It creates secure on-chip storage for secret code and software intellectual property. Code stored in the FlashVault will execute as normal, but cannot be read, copied or debugged, the company said.
Other features include peripheral event system that allows peripherals to send signals (events) directly to other peripherals without involving the CPU, a clock system with clock failure protection, frequency meter, real time clock with calendar mode, a precision crystal oscillator tuner and accurate digital frequency locked loop.
The device is supported by the AVR32 Studio integrated development environment used for Atmel’s AVR32 product line. The 64K byte flash version of AT32UC3L is priced at $1.96 in 10k units and the 16K byte flash version is priced at $1.47 in 10k units.
