ATMEGA8L-8MC

Overview

The ATMEGA8L-8MC is a low-power CMOS 8-bit microcontroller based on the AVR RISC architecture, manufactured by Microchip Technology. It features an 8KB In-System Programmable Flash memory, 512 bytes of EEPROM, and 1K byte of internal SRAM. The device operates within a voltage range of 2.7V to 5.5V and supports clock frequencies up to 8MHz. It includes 23 programmable I/O lines, three Timer/Counters, a 6-channel 10-bit ADC (PDIP package), USART, SPI, and TWI interfaces. The component utilizes a 28-lead PDIP package.

Feature Summary

• Advanced RISC architecture enabling single-clock cycle execution for high throughput efficiency.
• Non-volatile memory system with Read-While-Write capabilities and software security lock bits.
• Integrated peripheral suite including multiple timers, PWM channels, and analog-to-digital conversion.
• Five selectable power-saving sleep modes to optimize energy consumption in embedded applications.

Applications

• Consumer electronics requiring low-power operation
• Industrial control systems
• Automotive information systems

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 compatibility with existing PCB footprints for the 28-lead PDIP configuration before integration into new designs.

Selection Notes

Select this component for designs requiring a balance of processing speed and low power consumption at reduced voltages. The 8MHz speed grade suits applications where moderate performance is sufficient. Consider the PDIP package constraints for assembly methods and thermal management requirements compared to surface-mount alternatives.

Part Context

This part belongs to the ATmega8 family of 8-bit AVR microcontrollers. It shares the core CPU architecture and peripheral set with other variants but differs in operating voltage and maximum frequency specifications defined by its 'L' and '8' suffixes. It represents a cost-effective solution for general-purpose embedded control tasks.

Replacement Considerations

Direct substitutes include ATMEGA8L-8PU and ATMEGA8L-8AU, provided pin compatibility and package differences are addressed. Verify that alternative packages support the required mounting method and that electrical characteristics remain within design limits.
