Name
CYGPKG_HAL_CORTEXM_KINETIS_TWR_K40X256 -- eCos Support for the Freescale TWR-K40X256 development kit
Description
The Freescale TWR-K40X256-KIT is a development kit for Freescale Kinetis Cortex-M4 based micro-controllers. It covers K40 and K30 microcontroller
subfamilies. K40X256 is a high end member comprising 256 KiB FLASH, 256 KiB FlexMemory and 64 KiB SRAM,
as well as rich set of communication interfaces including USB, UARTs CAN, SPI and I2C.
K40 controllers also feature a Segment LCD controller, a DMA controller and a FlexBus
external memory interface. They are mixed signal devices featuring 16 bit ADC and 12 bit DAC.
Configuration
Hardware Setup
No changes to the factory default setup are necessary.
Clocking
The TWR-K40X256 uses an 8MHz crystal as a clock reference which is stated as a requirement in the platform package.
Memory
K40X245 has two 32KiB SRAM banks giving a total of 64KiB on chip SRAM.
