ATMEGA128L-8AU Description

Short technical summary and product information.

The ATMEGA128L-8AU is an 8-bit AVR RISC microcontroller manufactured by Microchip Technology. It features a high-performance AVR core with 133 instructions, most executed in a single clock cycle. The device offers 128KB of in-system self-programmable Flash memory, 4KB EEPROM, and 4KB internal SRAM.

 

Operating at a maximum clock frequency of 8MHz, it provides up to 8 MIPS throughput. The microcontroller includes 53 I/O lines, an 8-channel 10-bit ADC, dual USARTs, SPI, I2C, and PWM channels. It also features a JTAG interface for debugging and programming, brown-out detection, and a programmable watchdog timer.

 

The device is supplied in a 64-pin TQFP package (14x14mm) for surface mount assembly. It operates over an industrial temperature range of -40°C to 85°C and supports a supply voltage range of 2.7V to 5.5V. The component is RoHS compliant and lead-free.
