Overview
The EVA-X4300 is a fully static 32-bit x86-based processor that is compatible with a
wide-range of PC peripherals, applications and operating systems, such as DOS,
WinCE, Linux, and most popular 32-bit RTOSs (Real Time OS). It enables maximum
software re-use based on its feature of legacy compatibility. The EVA-X4300 inte-
grates 32 KB write-through direct map L1 cache, a PCI bus interface at 33 MHz, an 8/
16-bit ISA bus interface, SDR SDRAM, DDR2 SDRAM, a ROM controller, IPC (Inter-
nal Peripheral Controller) with DMA and interrupt timer/counter included, FIFO UART,
SPI (Serial Peripheral Interface), LPC (low pin count), a USB 1.1/2.0 host controller,
LoC (LAN on Chip), an IDE controller, and 256 KB flash within a single 581-pin BGA
package to form a an SoC (System-on-Chip) processor. The 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, the EVA-X4300 is able to operate in a
wide range of temperatures without additional thermal design. With the commitment
of long term supply guaranteed for the EVA-X4300, customers can extend product
life cycle and receive a maximum return on investment.
The EVA-X4300 provides an ideal solution for embedded systems and communica-
tion products (such as the thin client, NAT router, home gateway, access point and
tablet PC) producing optimal performance.
This system design guide provides detailed usage information of the highly inte-
grated EVA-X4300 SoC processor.
