ATMEGA128L-8MU

The ATMEGA128L-8MU is an 8-bit AVR microcontroller based on the advanced RISC architecture. It features 128KB of in-system self-programmable Flash memory, 4KB SRAM, and 4KB EEPROM with high endurance (10,000 Flash write/erase cycles and 100,000 EEPROM cycles). The device operates over a supply voltage range of 2.7V to 5.5V and a temperature range of -40°C to 85°C, making it suitable for industrial and automotive applications.

Peripheral features include two 8-bit and two 16-bit timer/counters, a real-time counter, up to 8 PWM channels (six with programmable resolution from 2 to 16 bits), an 8-channel 10-bit ADC, and a programmable watchdog timer with on-chip oscillator. Connectivity options include EBI/EMI, I²C, SPI, and dual USART interfaces. The microcontroller also integrates a JTAG interface for on-chip debugging and programming, as well as support for QTouch capacitive touch sensing.

The device is housed in a 64-VFQFN exposed pad package (9x9mm) for surface mount assembly. It provides 53 general-purpose I/O lines and includes brown-out detection, power-on reset, and an internal calibrated RC oscillator. Data retention is rated at 20 years at 85°C and 100 years at 25°C.
