ATMEGA8L-8PC

Overview

The ATMEGA8L-8PC is a low-power CMOS 8-bit microcontroller based on the AVR RISC architecture, manufactured by Microchip Technology. It features an 8K byte In-System Programmable Flash memory, 512 bytes of EEPROM, and 1K byte of internal SRAM. The device supports a supply voltage range of 2.7V to 5.5V and operates at clock frequencies up to 8 MHz. It includes three flexible Timer/Counters, a 6-channel 10-bit ADC (PDIP package), and multiple communication interfaces including USART, SPI, and TWI.

Feature Summary

• Advanced RISC architecture with single-clock cycle execution for high throughput efficiency
• Non-volatile memory system supporting true Read-While-Write operation and in-system programming
• Integrated peripheral suite including timers, PWM channels, and analog-to-digital conversion
• Five software-selectable power-saving modes to optimize energy consumption

Applications

• Embedded control systems requiring low power consumption
• Battery-powered consumer electronics devices
• Industrial monitoring and automation applications
• Smart home appliances and sensors

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm that the specific ordering suffix matches the required package type and temperature grade. Check current lifecycle status as older variants may be marked as Not Recommended for New Designs. Ensure compliance with relevant environmental regulations such as RoHS before finalizing procurement decisions.

Selection Notes

Select this model when a robust 8-bit solution with moderate memory capacity is required. Consider the PDIP package availability if through-hole mounting is necessary for the target application. Evaluate the 8 MHz speed limit against processing requirements. Compare against higher-speed variants if performance constraints exceed the L-series specifications.

Part Context

This component belongs to the ATmega family of microcontrollers, which are widely used in embedded applications due to their balance of performance and cost. The 'L' suffix indicates a low-voltage version optimized for lower power operation compared to standard voltage variants. The part utilizes the established AVR core architecture known for code efficiency.

Replacement Considerations

Direct substitutes include other ATmega8L variants with different packages, such as ATMEGA8L-8AU or ATMEGA8L-8MU. Cross-referencing pin compatibility and electrical characteristics is essential when replacing components within the same series.
