Embedded systems have been a major force in the technology industry for decades. In the early 1970s, embedded systems began to emerge as a way to provide enhanced services and features in a product or service. Today, embedded systems are complex and ever-evolving pieces of equipment designed for specific tasks, often in complex and changing environments. One such system is the N79E352APG, which is an embedded microcontroller. This article answers two questions: what is its application field, and what are its working principles?

Application Field of N79E352APG

The N79E352APG is an 8-bit embedded microcontroller, developed and manufactured by NXP Semiconductors. It is primarily used in various audio, video and communication applications, such as automotive electronics, consumer electronics, and industrial applications. For example, it is commonly used in audio systems, where it can provide digital sound processing and control, along with audio signal amplification and equalization, as well as data logging. It is also widely used in digital communication systems, where it can provide digital signal processing, such as for data transmission and reception, along with digital protocol control.

The N79E352APG features an 8-bit microcontroller core, with a wide range of peripheral features. These include support for up to 16KB of on-board RAM, 256Kb of Flash memory, and 4Kb of EEPROM memory. It also includes various timers, counters, and analog-to-digital converters, as well as integrated power management, and a Direct Memory Access (DMA) controller. These features, in combination with its large range of on-chip peripherals, make the N79E352APG an ideal choice for a wide variety of embedded applications.

Working Principles of N79E352APG

The N79E352APG has a RISC architecture, making it an efficient and versatile processor for embedded applications. The architecture is composed of 16 8-bit registers, with the Program Counter, Stack Pointer and Program Status Word (PSW) being used to store program and thread states. The registers are also used to access internal and external peripherals. The architecture also supports up to 16 levels of interrupt priority, as well as a Check-and-Restart mode, which allows for programming errors to be detected and corrected without effecting the application.

The N79E352APG is programmed using the NXP-defined MC68HC11 Assembly Language (MASL). This language is based on the Intel Assembly language, using customized commands and registers for the microcontroller. Programs are written and compiled using proprietary NXP software, and can then be loaded onto the microcontroller via a serial connection. This process allows for programming to be completed in a relatively short time, making the N79E352APG an ideal choice for cost-sensitive and time-sensitive applications.

In summary, the N79E352APG is an 8-bit embedded microcontroller, primarily used in audio, video, and communication applications. It features a RISC-based architecture, with 16 8-bit registers, and supports up to 16 levels of interrupt priority. It is programmed using the NXP-defined MC68HC11 Assembly Language, and can be programmed quickly and inexpensively. For these reasons, it is an ideal choice for a wide range of embedded applications.
