刚看了下 低端的lm3s1000系列 64pin 的价格都相当有杀伤力啊 ,
lm3s1607
50 MHz, with 128 kB flash, 32 kB SRAM, a 32-ch DMA, and ROM preloaded with the StellarisWare Driver Library and BootLoader.
The LM3S1607 also features real-time industrial connectivity,
with an SSI / SPI controller, 2 I2C interfaces, and 3 UARTs.
The microcontroller also features intelligent analog capability,
including .8 channels of highly accurate 10-bit analog-to-digital
conversion - with the ability to sample at speeds of 500K samples
per second. Finally, the LM3S1607 microcontroller provides a 24-bit systick timer,
4 32-bit or 8 16-bit general-purpose timers, a watchdog timer,
a battery-backed hibernation module with RTC and 256 bytes of
non-volatile state-saving memory, a low drop-out voltage
regulator so that only one supply voltage is required,
ps 有样片哦 1626也有样片
brown-out reset, power-on reset controller, and up to 33 GPIOs. |
