Introduction
EVA-X4300 is a fully static 32-bit x86-based processor that powers a wide-range of PC peripherals, applications and OSs, such as DOS, Windows CE, Linux and most popular 32-bit
RTOS (Real Time OS) for maximum software re-use and legacy compatibility. EVA-X4300 integrates comprehensive features and rich I/O flexibility within a single System on Chip, to
reduce board design complexity and shorten product development schedules. Taking advantage of ultra low power consumption, EVA-X4300 is able to operate in wide temperature
range environments without thermal designs, making them the perfect x86-based SoC for diverse embedded applications.
