“As the subsequent technology of Microchip 8-bit MCUs to combine USB connectivity, the AVR DU household is designed to supply enhanced safety features,” mentioned the corporate.
Safety comes from completely disabling write functionality inside the programming and debug interface after preliminary programming, and handing over replace to an inside safe bootloader which might usher in authorised in-field code updates over the USB interface.
On-board USB clock restoration removes the necessity for an exterior crystal.
The cores work as much as 24MHz and the components introduced at Embedded World right this moment had been:
AVR64DU28 64kbyte flash 28pins 4x4mm VQFN, SPDIP and SSOP
AVR64DU32 64kbyte flash 32pins 5x5mm VQFN and 7x7mm TQFP
In accordance with Microchip, the ICs additionally “assist energy supply of as much as 15W from the USB interface [enabling] USB-C charging with currents as much as 3A at 5V.”
As there isn’t any energy stage on the silicon, and the info sheet will not be serving to, Electronics Weekly has requested for clarification on this 15W functionality.
Related improvement instruments embody a software program stack for the USB peripheral, and there’s EV59F82A (left), a improvement board for AVR64DU32 with two USB Sort-C connectors, one for programming and debugging, and one linked to the IC’s USB peripheral.
Operation is over 40°C to +85°C
