ATME超低功耗的Cortex-M4

li_thomas · 发表于 2013-3-26 10:42:53

看了它的datasheet，功耗真是相当低，都可以拼单片机的功耗了，不过主频只能跑到48MHz。从它官网上拷了段介绍。

The Atmel® SAM4L microcontrollers (MCUs) redefine the power benchmark for Cortex™-M4 processor-based devices, delivering the lowest power in active mode (down to 90µA/MHz) as well as sleep mode with full RAM retention (1.5µA) with the shortest wake-up time (down to 1.5µs). Embedding Atmel picoPower® technology, the SAM4L family provides highly efficient signal processing, ease of use and high-speed communication peripherals—ideal for power-sensitive designs in the industrial, healthcare and consumer application areas.
Key Features
Atmel picoPower Technology — Ensures that devices are developed from the ground up for the lowest power consumption possible, enabling long battery life
Atmel QTouch Capacitive Touch Support — Includes hardware integrated capacitive touch module based on QTouch® technology for fast development of touch and proximity functionality with ultra low power consumption
Highly Efficient Signal Processing — Thanks to the Cortex-M4 architecture, the SAM4L microcontrollers feature extended single-cycle multiply-accumulate instructions, optimized SIMD arithmetic and saturating arithmetic instructions for highly efficient signal processing
Ease of Use — Its ecosystem of software tools and support for Atmel Studio 6 integrated development environment enables an efficient design process and reduces time to market

主要是货源和价格问题

M4 主频48M，确实有点低。
M0这主频还行。

货源应该不担心，现在atmel产能充足。
价格看量，肯定可以和竞争对手比的。

不过主打低功耗，应该是可以的，也不是所有应用都需要高频的。

这种应用到什么场合呢？

你是代理商？

手上刚拿到10pcs原厂给的ATSAM4LC4BA-UES还没来得及玩！

代理商应该不会问这种问题吧。呵呵。我只是好奇这种低功耗高处理速度的MCU应用场合。

ATMEL的M3推广的并不是很好。

liwei_jlu · 发表于 2013-3-27 14:03:15

ATMEL的M3市场反应，现在不要说ST，连nxp都不如。
感觉atmel在arm9火了一把后推广力度就不行了，再加上断货事件，现在cortex-m市场，很少简单atmel的身影。价格也高的要死。

你的信息不一定完整，但也有一定道理。
