Hi All
Freescale has now released their K70 - http://forums.freescale.com/t5/Kinetis-ARM-Cortex-M4/Freescale-now-offering-single-chip-graphics-LCD-Kinetis/td-p/91499
It has an integrated LCD controller and FPU and operates at up to 150MHz. Engineering samples are available today and also a board for the Tower Kit is orderable. The graphic LCD module that will go with the tower kit especially for the K70 should be available in January 2012 (the present TFT board has an internal controller and so connects via the FlexBus interface rather than the LCD controller).
It looks as though also ATOLLIC will be supporting the Kinetis range of devices so I will have a go at adding the K70 to the project and an Atollic project to the package. [I'll wait for the LCD board to be available before ordering the new Tower board though]

Hi All
As well as the new K70 (available in 196 pin or 256 pin MAPBGA) with up to 1Meg Flash, 128k SRAM, FPU and the LCD controller there is also a new part called the K61. The K61 is essentially a K70 without the LCD controller - it is available in 144 pin, 196 pin and 256 pin MAPBGA.
Comparing the biggest packages, the budgetary 10'000 piece prices are:
- K70 $10.08
- K61 $9.03
This means that the LCD controller costs $1.05.
However a design would also need some SDRAM connected to the K70 so that the image can be held in it (graphic RAM) which makes the cost of the LCD HW more than just the controller cost in the processor - especially when greater than 8 bit colour is used.

Hi All
The K70 boards are readily available for the tower kit but the LCD module to go with it is scheduled for mid Q2 - 2012 accoridng to latest information.
