NOTES:
1. Industrial temperature range product for the 15ns speed grade is available as a standard device. All other speed grades are available by special order.
2. Pulse widths less than minimum values are not allowed.
3. Values guaranteed by design, not currently tested.
Has anyone done the transplantation of Broadcom SDK? We are using BCM5387 and VxWorks RTOS now, and need to do this transplantation work. Please give me some advice, thank you....
I have been learning MSP430G2553 for more than 7 days. I personally think that low power consumption is its biggest highlight. It is very deliberate. Therefore, the interrupt/low power mode is very ch...
I am using IAR-3.40A version.After the program is compiled without errors, I press DEBUG to download the program, and the following error message will appear:"chosen derivative (msp430F449) and actual...
