Microchip ATMEGA169PA-MUR: A Robust 8-Bit AVR Microcontroller for Embedded Applications
The Microchip ATMEGA169PA-MUR stands as a highly integrated and powerful member of the renowned AVR microcontroller family. This low-power, high-performance device is engineered around an advanced RISC architecture, enabling most instructions to be executed in a single clock cycle. This allows the system to achieve throughputs approaching 1 MIPS per MHz, balancing computational power with efficient energy consumption—a critical requirement for battery-powered and portable embedded systems.
At the core of its capabilities is 16KB of self-programming Flash memory. This generous amount of non-volatile memory provides ample space for complex application code and offers the flexibility for in-system firmware updates, which is essential for field upgrades and product maintenance. Complementing the Flash is 1KB of internal SRAM for efficient data manipulation during runtime and 512B of EEPROM for storing critical parameters that must be retained even after a power cycle.
A defining feature of the ATMEGA169PA-MUR is its integrated LCD controller. This peripheral can directly drive up to 100 segments, making it an ideal solution for a vast array of applications requiring user interfaces, such as industrial control panels, medical devices, and consumer appliances. This integration eliminates the need for an external display driver, thereby reducing overall system cost and complexity.
The microcontroller is further equipped with a rich set of peripherals, including a versatile 16-bit timer/counter, USART, SPI, and an 8-channel 10-bit ADC, providing the necessary tools for sensor interfacing, data acquisition, and communication. Packaged in a 64-pad QFN (Microlead Frame), the ‘-MUR’ suffix denotes a tape-and-reel packaging suitable for automated assembly processes in high-volume manufacturing.
Operating over an extensive voltage range of 1.8V to 5.5V and across an industrial temperature range, this microcontroller ensures reliability and performance stability in diverse and demanding environments.
ICGOODFIND: The Microchip ATMEGA169PA-MUR is a top-tier choice for designers seeking a cost-effective, feature-rich 8-bit MCU. Its combination of substantial Flash memory, a built-in LCD driver, low-power operation, and a robust peripheral set makes it exceptionally well-suited for sophisticated embedded control systems with user interface requirements.
