EP7311-IB

The EP7311-IB is a single-chip RISC embedded microprocessor with integrated system peripherals. It was manufactured by Cirrus Logic and is designed to provide system designers with design flexibility, cost savings, and a standard I/O interface. By integrating all the essential components onto the one chip, it reduces circuit board size, simplifies power source and connectors, and minimizes software development time for system designers.

The EP7311-IB is widely used in embedded applications such as digital consumer products, office automation, industrial control and embedded communication systems. The device is embedded with the ARM920T high performance processor, 16 KiB SRAM, 512 KiB EPROM, 46 I/Olines, 4 SPI/SCI serial ports, 2 USB ports, a 10-bit ADC, and a PWM. It also features an integrated memory controller, an integrated power management and monitoring unit, an integrated power-on reset and an audio playback line.

The working principle of the EP7311-IB is that it has a 32-bit ARM processor running an operating system such as uC/OS-II or VxWorks, with integrated peripherals and external memory and I/O support. A typical application is an industrial control. In this way, all the separate components such as memory, I/O, and processors become one single entity. This simplifies the system, reduces costs, and increases reliability, making it a cost effective solution for many embedded applications.

The EP7311-IB also provides two approaches to developing applications: the embedded C language and assembly language. Embedded C programming is generally easier to use and faster to develop, whereas assembly language gives the user more control over the code and the hardware. Both methods can be used to develop robust and reliable applications, depending on the user’s skill and experience.

In summary, the EP7311-IB is a highly efficient embedded microprocessor that has been designed to provide cost savings and design flexibility to system designers. It is widely used in embedded applications such as digital consumer products, office automation, industrial control, and embedded communication systems. It features an integrated memory controller, integrated power management and monitoring unit, integrated power-on reset, audio playback line, as well as 46 I/O lines, 4 SPI/SCI serial ports, and 2 USB ports. The EP7311-IB offers two approaches for application development, assembly language and embedded C language.
