The new MCUs combine the company's ultra-low-power 78K0R/Kx3-L 16-bit CPU
with its USB 2.
The guts of the machine include a 16-bit CPU
, 128KB of memory, and a 6,000-pixel LCD display.
Its intelligent control module includes a GPU, 16-bit CPU
, 4MB flash memory, USB 2.
In most cases, the XA-C3's CAN co-processor reduces CPU overhead by up to 90% in comparison to conventional CAN microcontrollers, and typically uses less than 2% of the CPU resources for message handling, leaving almost 100% of the 16-bit CPU
core's resources available to run the application.
The R8C is a 16-bit CPU
, but the CPU and peripheral functions are linked by an 8-bit bus.
The new MCUs combine NEC Electronics' ultra-low-power 78K0R/Kx3-L 16-bit CPU
with NEC Electronics' USB 2.
A 16-bit CPU
interface with selectable timing modes allows direct connections to embedded system CPUs and eliminates the need for a separate device to control timing, which also reduces device count and conserves board space.
Built on a powerful 16-bit CPU
core, the R8C/3x MCUs with on-chip flash have an extended operating voltage range of 1.
5V and have a high-performance M16C/60 16-bit CPU
core, which enables the use of existing code.
