The ATMEGA88A-MMHR from Microchip Technology is a high-performance, low-power AVR 8-bit microcontroller that combines 8KB ISP flash memory, 1KB SRAM, 512-Byte EEPROM, and a rich feature set. This microcontroller is part of the popular ATmega series, known for its robust architecture, optimized instruction set, and versatility, making it ideal for a wide range of applications across various industries.
With a maximum operating frequency of 20MHz, the ATMEGA88A-MMHR can execute powerful instructions in a single clock cycle, achieving throughputs approaching 1 MIPS per MHz and balancing power consumption and processing speed. It operates within a voltage range of 1.8-5.5V, allowing for flexible power management and compatibility with both 5V and 3.3V systems.
The device's advanced RISC architecture enables the ATMEGA88A-MMHR to perform well in applications requiring a high level of control, such as sensor systems, automotive components, home automation, and IoT devices. Additionally, its 23 general-purpose I/O lines, 32 general-purpose working registers, three flexible timer/counters with compare modes, internal and external interrupts, serial programmable USART, a byte-oriented 2-wire serial interface, SPI serial port, and a 6-channel 10-bit A/D converter (eight channels in TQFP and QFN/MLF packages) provide designers with ample resources for complex tasks.
The ATMEGA88A-MMHR also features power-saving modes such as Idle, ADC Noise Reduction, Power-save, Power-down, and Standby, allowing for efficient power management in battery-operated applications. Furthermore, its programmable brown-out detection and internal calibrated oscillator contribute to the reliability and stability of the system without requiring additional external components.
Packaged in a 28-pin QFN, the ATMEGA88A-MMHR is designed for space-constrained applications. Its compact size, coupled with its extensive set of peripherals and interfaces, makes it an excellent choice for embedded systems that require a small footprint without compromising on functionality.
