We'll have to wait for STM32F042 for those.</p> <p>I think the combination of crystal-less Full-Speed USB, with a manufactured-in USB bootloader may be the 'killer' feature. </p> <p>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.</p> <p>Like most STM32F's, it has a good set of peripherals. Unusually for a 'low-end' part, it includes<br /> - dual channel DAC,<br /> - I2S,<br /> - capacitive touch sensing<br /> - comparators.</p> <p>It is 'only' a 48MHz Cortex-M0, but that is a lot of computer.<br /> 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.</p> <p>I haven't done the analysis, but I think it would be feasible to simplify one my Orone-mini designs to get it working.</p> <p>Well done ST Micro. Thank you.<br /> Now we'd like it in a 28pin Dual-in-Line package, so we can use it on stripboard/veroboard, please. </p> http://forums.leaflabs.com/topic.php?id=74264#post-105190 Tue, 21 Jan 2014 01:57:26 +0000 bobricius 105190@http://forums.leaflabs.com/ <p>wav, dream is reality :) <a href="http://www.st.com/web/en/press/p3496" rel="nofollow">http://www.st.com/web/en/press/p3496</a></p> <p>Tsop20, no crystall, realy great news</p> <p><a href="http://www.st.com/web/catalog/mmc/FM141/SC1169/SS1574/LN1823?icmp=stm32f0x2-line_pron_pr_jan2014" rel="nofollow">http://www.st.com/web/catalog/mmc/FM141/SC1169/SS1574/LN1823?icmp=stm32f0x2-line_pron_pr_jan2014</a> </p>
