ATMEGA8L-8AU

The ATMEGA8L-8AU is an 8-bit AVR microcontroller from Atmel, featuring high-performance RISC architecture with 130 instructions, most executed in a single clock cycle. It provides 8KB of in-system self-programmable Flash memory, 1KB SRAM, and 512 bytes of EEPROM with high endurance (10,000 Flash/100,000 EEPROM write/erase cycles) and long data retention (20 years at 85°C / 100 years at 25°C).

This device operates at a maximum speed of 8 MHz and a supply voltage range of 2.7V to 5.5V. It includes 23 programmable I/O lines, an 8-channel 10-bit ADC, and peripherals such as three PWM channels, brown-out detection, power-on reset, and watchdog timer. Communication interfaces include I²C, SPI, and UART/USART.

The microcontroller is available in a 32-TQFP surface mount package (7x7 mm) and is specified for an operating temperature range of -40°C to +85°C. Typical power consumption is 3.6 mA in active mode at 4 MHz, 3V, with low-power sleep modes including idle, power-save, and power-down (0.5 µA). It features an internal calibrated RC oscillator, eliminating the need for external clock components in many applications.

Designed for embedded control applications, the ATMEGA8L-8AU is suitable for industrial, automotive, and consumer systems requiring a balance of performance, low power, and rich peripheral set. The part is RoHS3 compliant and has an MSL rating of 1 (unlimited).
