STM32F0x2 crystal-less USB 2.0 FS enlarges the STM32 F0 series with up to 128 Kbytes of Flash and 16 Kbytes of SRAM
These new STM32 F0 devices offer a crystal-less USB 2.0 FS interface with a link power management (LPM) feature and compliant with battery charger detection (BCD) specification 1.2, thus eliminating the need for an external crystal oscillator to generate the precision clock required by the USB protocol. Together with the support of CAN, USART, I²C, SPI (I²S) and HDMI CEC, the new STM32 F0 devices enable product developers to increase system integration, reduce costs, and exceed the traditional price/performance limitations imposed by older, proprietary 8-bit or 16-bit microcontrollers for USB device or USB- controller applications.
The STM32F072 series provides 64 to 128 Kbytes of Flash memory in 48-, 64- or 100-pin packages. The STM32F042 series comprises variants with 16 to 32 Kbytes of Flash memory and 20-, 28-, 32- and 48-pin package options.
