Overview
The ATTINY48-MUR is an 8-bit AVR microcontroller featuring 4K bytes of In-System Programmable Flash, 64 bytes of EEPROM, and 256 bytes of SRAM. It utilizes a VQFN-32 package with 28 I/O lines and operates at clock frequencies up to 12 MHz. The device supports a supply voltage range of 1.8V to 5.5V and functions within an industrial temperature range of -40°C to +85°C.
Feature Summary
- Advanced RISC architecture executing most instructions in a single clock cycle for high throughput efficiency.
- Integrated non-volatile memory segments including ISP Flash, EEPROM, and internal SRAM with data retention capabilities.
- Comprehensive peripheral set comprising dual timer/counters, a 10-bit ADC, SPI, TWI interfaces, and an analog comparator.
Applications
- Embedded control systems requiring low power consumption
- Industrial devices utilizing the industrial temperature rating
- Battery-powered applications supported by multiple sleep modes
Procurement Notes
Verify the specific suffix against official Microchip documentation to confirm package type and environmental rating. Ensure compatibility with existing PCB footprints for the VQFN-32 configuration. Confirm that the selected revision matches the required firmware programming interface specifications.
Selection Notes
Select this component when a balance of processing speed and power efficiency is required for compact designs. The 32-lead QFN package suits space-constrained applications. Evaluate the 12 MHz performance grade against system timing requirements to ensure adequate processing headroom.
Part Context
This part belongs to the ATtiny48/88 family of 8-bit AVR microcontrollers manufactured by Microchip Technology. It shares architectural similarities with other members of the series but is distinguished by its specific 4KB Flash capacity and 32-lead VQFN packaging configuration.

FAQ
What is the function of the PC6 pin?
PC6 serves as the RESET input by default. If the RSTDISBL fuse is programmed, it functions as a general-purpose I/O pin.
How does the device handle power saving?
It offers three software-selectable modes: Idle, ADC Noise Reduction, and Power-Down, allowing optimization of power consumption versus processing speed.
