This device, based on the 8052 core, combines leading-edge microcomputer technology with functional extensions, resulting in a high-performance, low-power controller with on-chip flash memory, making it ideal for high-reliability applications with cost effectiveness as a primary feature.

The TS87C52X2-VCE microcontroller has two embedded 8-bit CPU cores and two buses, referred to as the busA and busB. It also has two active peripherals, namely the SCI and I2C modules. It provides the following features:

• 28K Bytes of on-chip Flash memory with fast fetch architecture
• 2K Bytes of RAM, to be used for any purpose or as registers
• Two independent 8-bit CPU cores
• Eight 32-bit timers
• Three dedicated serial I/O ports
• 16-bit DMA controller
• Power down support

The TS87C52X2-VCE\'s primary application field is in industrial automation, robotics, and high-end low-power applications. With its features and its power-saving features, it can help to make high-speed and reliable systems for various industrial machines. It is also used in the development of motor control systems and power converters.

The TS87C52X2-VCE microcontroller supports multiple programming languages and interfaces, such as C, assembly, and JTAG. It also supports IEEE 1149.1 compliance, which helps to drastically reduce development time. Furthermore, it has built-in safety features such as the option to lock or erase the flash memory. Those features help ensure the device can be reliably used in a stable environment.

The working principle of the TS87C52X2-VCE microcontroller is based on the Von-Neumann architecture and Two-bus scheme. This architecture is usually used in embedded systems, and it has two main parts, the Central Processing Unit (CPU) and the Memory. The CPU is responsible for all the calculations, while the memory stores the retrieved data and instructions needed for processing. The TS87C52X2-VCE operates in a distributed fashion, with the two CPUs working simultaneously. The device works in three stages. First, instructions are retrieved and decoded by the CPU. Then, the instructions are executed, resulting in data and instructions being stored in the memory. Finally, the data and instructions are retrieved from the memory and executed by the CPU.

The TS87C52X2-VCE microcontroller has revolutionized embedded system design, and has found its way into many applications. Its combination of a two-bus architecture, low-power and high-performance, make it a reliable choice for a variety of applications.
