Introduction

The TMS370C756AFNTQ1 is a single-chip microcontroller from Texas Instruments’ TMS370 family. This device is a multi-functional, cost-effective solution for embedded applications. It offers up to 28 bits of powerful processing with five timer/event counters, two serial ports, a 32-bit arithmetic logic unit (ALU), and an internal voltage regulator. The integrated analog-to-digital converter (ADC) and advanced true static power saving modes make it an ideal choice for battery operated devices.

Application Fields

The TMS370C756AFNTQ1 can be used in a variety of applications, ranging from industrial control, automotive, security systems, consumer electronics and many more. Industrial applications include programmable logic controllers (PLCs) and the efficient control of industrial processes, motors and robotics. In automotive, the device can be used for powertrain and body control, including fuel injection systems, temperature and speed control. The TMS370C756AFNTQ1 is also used in consumer applications such as washing machines, refrigerators, and white goods.

Processor Core

The TMS370C756AFNTQ1 is powered by a 16-bit, two-stage pipeline TMS370PE core, allowing execution of up to 28-bit instructions. The core can handle both 8-bit and 16-bit operations and provides instruction set compatibility with the 80C186E processor. This feature helps port existing 8-bit and 16-bit code to the device without changing the code structure. The core is also optimized to facilitate real-time operation, allowing instruction execution in as little as one machine cycle.

Timer/Event Counters

The processor is equipped with five timer/event counters, four of them operated under software control and one operated by the internal real-time clock/calendar (RTCC). These timers and event counters can be used for real-time clock/calendar and for measuring the time of events and intervals. The RTCC can be used for a variety of time-keeping applications, such as alarm functions, time-stamping, etc.

Serial Interfaces

The TMS370C756AFNTQ1 provides two serial interfaces. The first is an enhanced serial port (ESP) which supports SPI and I2C, allowing data transfer at high speed without the need for additional external hardware. The second is an asynchronous serial communication interface (ASCI) which can support asynchronous, synchronous and UART data formats. Both interfaces offer high performance without the need for specialized external control hardware.

Arithmetic Logic Unit

The integrated arithmetic logic unit (ALU) can perform a wide range of operations, including 8-bit and 16-bit addition, subtraction, multiplication, and division. The ALU can also be used for table look-ups, bit manipulation and comparison operations.

Analog-to-Digital Converter

The integrated analog-to-digital converter (ADC) allows the processor to convert analog signals into digital representations. This feature makes the device ideal for reading analog signals from sensors, such as temperature, pressure or light.

Power Saving Modes

The TMS370C756AFNTQ1 features advanced static power saving modes. These modes reduce the power consumption of the device when idle and improve overall system performance and battery life. The three power saving modes are Idle mode, Sleep mode and Deep Sleep mode.

Conclusion

The TMS370C756AFNTQ1 is an excellent choice for embedded applications. Its powerful processor core and integrated peripherals enable it to handle a wide range of applications with excellent performance and power saving capabilities. Its versatile timer/event counters, serial interfaces, arithmetic logic unit and analog-to-digital converter make it an extremely useful and cost effective solution for embedded applications.
