The Microchip Technology ATMEGA128A-PU is an 8-bit AVR RISC microcontroller featuring 131KB of FLASH program memory and 16KB of SRAM. Operating at up to 20MHz, this component includes 32 general-purpose I/O lines, 8 channels of 10-bit Analog-to-Digital conversion, and multiple peripherals such as two USARTs, SPI, and I2C interfaces. It also supports 8 PWM channels, 4 timers, an Analog Comparator, Brown-Out Detection (BOD), and Power-on Reset (POR). The device operates over a temperature range of -40°C to +85°C with a supply voltage range of 5.0V to 5.5V, and can function at lower voltages and frequencies (e.g., 2.7V @ 10MHz, 1.8V @ 4MHz). This microcontroller is suitable for applications in industrial automation, consumer electronics, and embedded control systems. The ATMEGA128A-PU is housed in a 40-pin PDIP package.
