The AVR64DB48T-E/PT from Microchip Technology (formerly Micrel) is an 8-bit microcontroller unit designed to deliver robust performance in embedded applications requiring efficient processing and versatile I/O capabilities. This IC belongs to the Embedded Microcontrollers category within the broader Integrated Circuits classification and is part of Microchip's AVR DB series, which addresses design challenges related to power efficiency, analog integration, and flexible connectivity in space-constrained applications.
At its core, this microcontroller features an 8-bit AVR processor running at 24MHz, providing reliable computational power for real-time control applications. The device incorporates 64KB of flash program memory (organized as 64K x 8), offering substantial space for complex firmware implementations, while 8KB of RAM (8K x 8) ensures adequate working memory for data processing tasks. Additionally, the integrated 512-byte EEPROM provides non-volatile storage for configuration parameters and critical data retention across power cycles.
The AVR64DB48T-E/PT excels in mixed-signal applications with its comprehensive data conversion capabilities, featuring 18 channels of 12-bit analog-to-digital converters and one 10-bit digital-to-analog converter, making it ideal for sensor interfacing and analog signal processing. The device provides 40 general-purpose I/O pins in a compact 48-pin TQFP package (7x7mm), maximizing pin availability while maintaining a small footprint suitable for space-sensitive designs. Connectivity options include I²C, SPI, and UART/USART interfaces, enabling seamless communication with peripheral devices and other system components.
Key protective and timing peripherals include brown-out detection/reset, power-on reset (POR), pulse-width modulation (PWM) for motor control and dimming applications, and a watchdog timer (WDT) for system reliability. The internal oscillator eliminates the need for external crystal components, simplifying board design and reducing bill-of-materials costs. Operating across an exceptionally wide voltage range of 1.8V to 5.5V and temperature range of -40°C to 125°C, this microcontroller demonstrates excellent environmental tolerance for industrial, automotive, and harsh-environment applications.
The surface-mount TQFP package facilitates automated assembly processes, and the device is supplied in tape and reel format for high-volume manufacturing. Full RoHS3 compliance ensures environmental responsibility and regulatory adherence for global markets. Primary advantages include the combination of rich analog peripherals, extensive flash memory, wide operating voltage range, and high I/O count in a compact package, making it particularly suitable for industrial control systems, smart sensors, battery-powered devices, motor control applications, home automation, IoT edge devices, and portable instrumentation.
