TSC8051I2 8-bit Microcontroller with I2C Interface
In today's electronic systems, communication between components is of major importance. On-board component functions are becoming more and more complex and there is an increasing need to interface with external systems. Microcontrollers, as the core of many systems, influence the methods used by designers to implement inter-IC communication on their applications. Therefore, providing microcontroller solutions with industry standard serial interfaces, helps design implementation. UARTs have been used in microcontrollers since decades for serial links but have some limitations. Progressively the I2C bus has been adopted as the industry standard for multi IC serial communication where 400 kbit/smaximum speed fits the application needs.With only 2 active wires, it provides a flexible bi-directional communication with multi-master capability (more than one IC in master position) allowing easy and powerful implementation. The TSC8051I2 is an 8-bit microcontroller, based on the marketleading 80C51 Intel architecture. In addition to standard UART it comprises a multi-master I2C controller, offering a cost effective solution to implement I2C based systems. With up to 12 programmable 8-bit PWM channels it allows driving of external analog peripherals. An enhanced watchdog and power monitoring features enables implemention of secure designs. The TSC8051I2 includes a 256 byte RAM data memory and a 8 Kbyte ROM or EPROM/OTPprogram memory. The TSC8051I2 is especially adapted for industrial and video-audio applications, but also fit in phones, telephony systems and computer peripherals.
