Overview of AT87C58X2-SLSUL

The AT87C58X2-SLSUL microcontroller from Atmel is an 8-bit fully integrated device that combines a wide range of features typically found in larger microcontrollers. It includes a 40-pin wide footprint, an oscillator, basic timer/counter functions, interrupt structures, and a few built-in peripherals. The AT87C58X2-SLSUL is designed to support the industry-standard interchangeable architecture, which is the combination of the MCS-51 architecture, the AT89CXX instruction and AT89CXXX data formats, and the extended X1 bus architecture.

Applications of AT87C58X2-SLSUL

The AT87C58X2-SLSUL microcontroller is extensively used in automotive, industrial, medical and consumer applications. Its low pin count and program memory capacity make it well suited for applications that require a small form factor, such as remote controls and security systems. Its fast speed, low power consumption and general-purpose I/O make it suitable for applications that require frequent, rapid data acquisition and control. The AT87C58X2-SLSUL is also suited for applications requiring high accuracy. Its 8-bit architecture gives it a high instruction accuracy and its various timers are capable of generating precise and repeatable signals. This makes it ideal for applications such as frequency control, motor speed control, and temperature control.

Working Principle of AT87C58X2-SLSUL

The AT87C58X2-SLSUL microcontroller is a single-chip 8-bit microcontroller which consists of the CPU and several peripheral devices, including RAM, ROM, timer/counters and I/O ports. It uses a modified Harvard architecture in which the CPU can directly address non-volatile program memory (ROM) and read/write data memory (RAM) in the same memory space, allowing multiple instructions to be executed concurrently. The AT89C58X2-SLSUL operates with an external 8 MHz oscillator, and internal 9-bit addressable timer (T0), two 8-bit timer/counters (T1,T2), and two 16-bit timer/counters (T3,T4). The internal communication buses and the serial port are also part of the core peripherals. The AT87C58X2-SLSUL has an 8-bit modified Harvard architecture, where instruction and data memory spaces are separate but addressable in the same memory space. This architecture requires the user to tailor the program to the available memory thereby optimizing code size and execution time. It supports up to 64KB of program memory, 2KB of data memory, four external data buses and 32 address lines providing access to greater than 4MB of external memory.In order to communicate with external devices, the AT87C58X2-SLSUL offers an array of serial I/O interfaces including USART, SPI, I2C, and USB. It also has an on-chip watchdog timer, power down mode, sleep mode, and hardware debugging capabilities.

Conclusion

In conclusion, the AT87C58X2-SLSUL microcontroller from Atmel is an excellent choice for cost-sensitive applications requiring the integration of multiple peripherals on a single chip. Its wide range of features and low pin count make it well suited for automotive, industrial, medical, consumer, and security applications. Its 8-bit architecture and reliable timer functions make it an ideal choice for applications that require precise and repeatable signals.
