The TS80C31X2-LCE is an advanced 8-bit single-chip microcontroller (MCU) with an 8-bit CPU that is well-suited to embedded applications. It is a medium- to low-cost controller with features for low-power applications, including an integrated system clock, memory management unit (MMU), and an on-chip PowerOn Reset (POR) circuit. Additionally, it provides a wide range of peripherals, such as a serial communication interface, three timer/counters, and programmable oscillator.

Application Field and Working Principle

The TS80C31X2-LCE MCU finds many applications in embedded systems and peripherals, such as: industrial robotics, medical equipment, wearable electronics, appliance control, automotive electronics, and railway control systems. Other uses of the MCU include controllers for appliances, power supplies, UPS systems, and other similar applications.

At the core of the MCU is an 8-bit CPU that executes instructions at 8 MIPS (Million Instructions Per Second). The CPU performs all the instructions normally associated with an 8-bit core, including instructions for arithmetic, logic, data movement, data manipulation, and program control. The internal program counter (PC) provides the address of the current instruction, while the internal data pointer (DP) points to the address of data memory. The MCU also contains eight 8-bit), two 16-bit, and two 24-bit general-purpose registers, as well as two 16-bit stack pointers.

The MCU also contains an MMU, which provides a useful form of memory organization and overlaps with the interrupt system and the timer circuit. Memory is available in the form of internal RAM blocks in both fixed (ROM) and variable (RAM) memory types. The MCU can access up to 32KB of external code memory (EPROM/Flash memory) using an on-chip program address decoder for program storage and execution. The on-chip RAM can hold up to 128 bytes and data can be written directly into RAM or EPROM code memory.

In addition to the CPU, the MCU also includes a serial port, a watchdog timer, three timer/counter units, a programmable oscillator, and an on-chip reset circuit. The serial port can be used to communicate with external devices, while the timer/counters can be used to measure and control time-based operations. The watchdog timer prevents runaway code by resetting the MCU if the program hangs or if normal program control is lost. The programmable oscillator can be used to generate clock signals for the MCU and peripheral devices, and the reset circuit helps to reset the MCU after a system crash.

The TS80C31X2-LCE MCU is a low-cost, high-performance solution for embedded systems. It can be used in a wide range of embedded applications, from industrial automation and control systems to medical and automotive electronics. With features for low-power applications, such as an integrated system clock, MMU, and on-chip POR circuit, it offers a versatile and cost-effective choice for embedded system designers.
