ATMEGA8L-8MUR

Overview

The ATMEGA8L-8MUR is a Microchip Technology 8-bit AVR RISC microcontroller featuring an 8MHz maximum clock frequency and operating within a 2.7V to 5.5V voltage range. It integrates 8KB of In-System Programmable Flash, 1KB SRAM, and 512B EEPROM. The device utilizes a 32-pad QFN/MLF package with 23 programmable I/O lines. Peripheral resources include three Timer/Counters, six 10-bit ADC channels, SPI, USART, and TWI interfaces.

Feature Summary

• Advanced RISC architecture enabling single-clock cycle execution for high throughput efficiency
• Non-volatile memory segments supporting true read-while-write operations and in-system programming
• Multiple software-selectable power-saving modes including idle, power-down, and standby
• Integrated analog-to-digital converter with ten-bit accuracy and on-chip analog comparator

Applications

• Embedded control systems requiring low-power operation
• Battery-powered consumer electronics devices
• Industrial monitoring applications utilizing sensor inputs
• Communication modules employing serial data interfaces

Procurement Notes

Verify the specific ordering suffix against official Microchip documentation to confirm package type and temperature grade. Confirm current lifecycle status as availability may vary. Ensure ESD handling protocols are followed during assembly due to the surface-mount QFN/MLF configuration. Cross-reference pinout diagrams with PCB layout requirements before finalizing component selection.

Selection Notes

Select this model when a low-voltage 8MHz performance level is required for space-constrained designs. The QFN/MLF package offers a compact footprint suitable for dense PCB layouts. Consider the 6-channel ADC limitation compared to TQFP variants if more analog inputs are needed. Evaluate power consumption specifications against battery life requirements for portable applications.

Part Context

This component belongs to the ATmega8 family of 8-bit AVR microcontrollers manufactured by Microchip Technology. It shares architectural similarities with other ATmega8 variants but differs in package style and speed grade. The 'L' designation indicates low-voltage operation capabilities, while the 'MUR' suffix specifies the specific surface-mount packaging configuration.
