8-Bit Microprocessor Offers PC Connectivity On A Smaller Scale
The eZ80 Webserver delivers Internet connectivity in applications where PC implementations are not feasible. The 8-bit microprocessor features the CPU, operating system, and connectivity of a PC on a smaller scale.

Operating at 50 MHz from a 3-V supply, the chip features the Embedded Webserver Software Suite, which implements 15 Internet protocols, including TCP/IP and HTTP. An on-chip oscillator, 8 kbytes of SRAM, and two universal UART, SPI, or I2C interfaces are also included. The Internet-compliant stacks allow end-users to remotely manage, control, diagnose, and reconfigure their applications without a dedicated PC using any Internet browser.

The solution consists of the eZ80 core, the Embedded Webserver Software Suite, a multiply-accumulator engine, peripherals, and development tools. It addresses 16 Mbytes without a memory management unit (MMU). Also, it performs 24-bit arithmetic for higher throughput.

In 10,000-unit quantities, the eZ80 Webserver costs $8.15.
