60 MHz core with 40 KB SRAM and 256 KB Flash. SRAM supports a USB stack plus application heap; Flash holds firmware with field-update capability over USB or UART.
Internal brown-out detect and POR circuits maintain reset integrity across supply dips.
It is designated Not Recommended for New Design (NRND), not fully discontinued. Production continues through the surplus channel, but new designs should not select this part.
Yes, it includes a USB 2.0 Full-speed device controller with integrated on-chip PHY, supporting device-mode connections.
The supply range is 3.0 V to 3.6 V.
