ATMEGA1284P-MU

The ATMEGA1284P-MU is a high-performance, low-power 8-bit AVR microcontroller based on advanced RISC architecture. It executes 131 powerful instructions, most in a single clock cycle, achieving up to 20 MIPS throughput at 20MHz. The device features 128KB of in-system self-programmable Flash memory, 16KB SRAM, and 4KB EEPROM with high endurance (10,000 Flash/100,000 EEPROM write/erase cycles) and data retention of 20 years at 85°C or 100 years at 25°C.

Peripherals include two 8-bit and one 16-bit timer/counter, an 8-channel 10-bit ADC, 6 PWM channels, and connectivity via I2C, SPI, and UART/USART. It also includes a JTAG interface for boundary-scan and on-chip debug, brown-out detection, power-on reset, watchdog timer, and multiple sleep modes (Idle, ADC Noise Reduction, Power-save, Power-down, Standby, Extended Standby) for power optimization.

The microcontroller operates over a wide voltage range of 1.8V to 5.5V and a temperature range of -40°C to 85°C. It is housed in a 44-VFQFN exposed pad package (44-VQFN 7x7mm) for surface mount assembly. This device is suitable for a variety of embedded applications including industrial control, consumer electronics, and sensor interfacing.
