You have read the data sheet so you do know that the LPC43xx has an external memory bus for SRAM, ROM, NOR flash, and SDRAM devices.
Or use the A15
you cannot expect a Cortex M3/M4 (~$10) to compete with a Cortex A15 (~$50 + DDR3 cost + FLASH cost), probably $100 total hardware cost.
now add markup and profit.
now add 1 to 5 in each vehicle?
This had better be good if it raises the cost of the vehicle by several thousand dollars.
Hi,
we all know the features of LPC43xx , and for many applications , these features and peripherals are very good and enough.
we all know the price levels of these microcontrollers/processors chips families . ( also the application section of these devices )
but in the progress roadmap of IC Design technologies , we can imagine and expect all prementioned requests.
( Integration of external memories on the top of CPU chip , then many of bus problems will not be the headache )
( making some modules for / power/analog in/analog out/digital in/digital out/ ethernet pack/ display pack/ ... such as puzzle parts/ )
( massive processing capability for current and future applications )
know for many advanced applications that we need very expensive FPGA chips,
for production and marketing of them, at the current time, there is not a direct inexpensive solutions.
so, someone from vendors should step ahead and solve this.
