Microchip ATMEGA8535L-8AUR: An 8-bit AVR Microcontroller for Embedded Control Applications

The Microchip ATMEGA8535L-8AUR stands as a quintessential component in the realm of embedded systems, representing the robustness and versatility of the classic 8-bit AVR microcontroller architecture. This particular device, housed in a compact 44-pin TQFP package, is engineered to deliver a balanced combination of performance, power efficiency, and integration, making it an ideal cornerstone for a vast array of control-oriented applications.

At its core, the ATMEGA8535L-8AUR operates at a maximum frequency of 8 MHz with a supply voltage as low as 2.7V, a feature denoted by the 'L' in its part number signifying its low-power capability. This makes it exceptionally suited for battery-powered and energy-sensitive devices. Despite its 8-bit data bus, the microcontroller leverages the AVR RISC architecture to execute powerful instructions in a single clock cycle, achieving throughputs approaching 1 MIPS per MHz, thus ensuring highly efficient and deterministic control for real-time applications.

The integrated feature set of this microcontroller is what truly empowers designers. It boasts 8 KB of In-System Self-Programmable Flash memory for flexible application code storage, 512 Bytes of EEPROM for critical data retention, and 512 Bytes of internal SRAM. Its rich peripheral suite includes:

Three flexible timer/counters with compare modes.

A versatile 10-bit ADC with 8 channels, enabling precise analog sensor interfacing.

Programmable Serial USART, SPI, and a byte-oriented 2-wire Serial Interface (I2C) for comprehensive communication.

A programmable Watchdog Timer and an internal calibrated oscillator for enhanced reliability and component count reduction.

The primary strength of the ATMEGA8535L-8AUR lies in its application scope. It is perfectly matched for demanding embedded control tasks such as industrial automation, sensor systems, motor control, automotive electronics, and a wide range of consumer products. Its ability to manage multiple input/output operations, process analog signals, and communicate with other digital components establishes it as a complete system-on-chip solution for countless projects.
