The application targeted for this new processor is medical space...what kind of medical devices? This does not seem to be a powerful MCU. Just enough for smaller applications...though it is good see that the tiny MCUs have display controller. Is 16-bit accuracy enough for the medical devices? The ADCs have 12-bit resolution; but 16-bit accuracy is achieved through hardware over-sampling. This could be okay for the medical devices for non-critical applications and for wearable medical electronics devices...and I believe that is what it is targeted for being low power device. There are so many low power MCUs in this space...how does this MCU compares with its competitors?
From my experience, the ADC is pretty norma since most of TIs comparable chips have a max of 16 bit accuracy with oversampling and are 12 bits in normal op. The power consumption is low here but if I were to chose between an SoC like CC430 or CC2540 and this chip I'd choose TI because of the bluetooth 4.0 or radio on the chips I mentioned and they also happen to be pretty small. We need to see more SoCs with wireless and also ultralow power. For now TI dominates that market I think.
Replay available now: A handful of emerging network technologies are competing to be the preferred wide-area connection for the Internet of Things. All claim lower costs and power use than cellular but none have wide deployment yet. Listen in as proponents of leading contenders make their case to be the metro or national IoT network of the future. Rick Merritt, EE Times Silicon Valley Bureau Chief, moderators this discussion.
