STM32F0x2 line with crystal-less USB 2.0

Moderatorbobricius - You beat me :-)
I've written a blog about my initial impression of the STM32F072 and STM32F072B-DISCO low-cost development board.
I wonder if this is a renamed STM32F052, which was described at several presentations more than a year ago?
The first parts are STM32F072, which are not offered in TSOP 20 packages. We'll have to wait for STM32F042 for those.
I think the combination of crystal-less Full-Speed USB, with a manufactured-in USB bootloader may be the 'killer' feature.
It does not need a JTAG/ST-link programmer, or even a USB-to-UART cable to get programs onto it. Make a board, plug in USB, upload and go. That makes it functionally comparable to STM32F105/7, STM32F3, or STM32F4, and hopefully less cost than STM32F103.
Like most STM32F's, it has a good set of peripherals. Unusually for a 'low-end' part, it includes
- dual channel DAC,
- I2S,
- capacitive touch sensing
- comparators.It is 'only' a 48MHz Cortex-M0, but that is a lot of computer.
The press release says $1.32 for 64KiB Flash, 16KiB SRAM, 48 pin package 10,000 off. I haven't seen distributer prices yet, but it's likely comparable or maybe cheaper than ATmega328; STM32F051 was.I haven't done the analysis, but I think it would be feasible to simplify one my Orone-mini designs to get it working.
Well done ST Micro. Thank you.
Now we'd like it in a 28pin Dual-in-Line package, so we can use it on stripboard/veroboard, please.Posted 2 years ago #
