16-bit, 75 MHz RISC microprocessor with Ethernet and RS-232 connectivity
Introduction
With the Ethernet protocol becoming the de facto network of choice for ever
more professional, office, industrial, and even home environments, it makes
sense to develop new systems and leverage existing ones to take advantage
of Ethernet connectivity.
Advantech’s EVA-X1610C integrates 10/100 Ethernet and RS-232 connectivity
into an economical 80C186-compatible 75MHz RISC microprocessor, putting
the Ethernet within reach of a host of applications.
Best Performance-to-Cost
The EVA-X1610C is a 16-bit, high performance, RISC architecture
microprocessor with 80C186 compatibility. Additional functions integrated
on the chip are: SDRAM controller, non-multiplexed address bus, interrupt
controller, DMA controller, timers, watchdog timer, FIFO UART serial ports,
programmable I/O (PIO) pins and fast Ethernet MAC (Media Access
Controller).
The advanced internal high-speed local bus architecture significantly increases
overall system performance. And high performance plus high integration
enable the EVA-X1610C to increase functionality while reducing BOM system
costs. This, combined with a royalty-free real-time OS, contributes to its
highly advantageous performance-to-cost ratio. The EVA-X1610C has been
designed to meet the communication requirements of products such as device
servers, medical monitors, industrial machines, scales, security systems,
code scanners, shared IP devices, thermostats, and wireless access points.
