ATMEGA8L-8PI

Overview

The ATMEGA8L-8PI is a low-power CMOS 8-bit microcontroller based on the AVR RISC architecture, manufactured by Atmel. It features an 8KB In-System Programmable Flash program memory, 512 Bytes EEPROM, and 1Kbyte Internal SRAM. The device operates within a voltage range of 2.7V to 5.5V and supports a maximum clock frequency of 8MHz. It utilizes a PDIP-28 package and provides 23 I/O pins with six-channel 10-bit ADC capability. The component is rated for industrial temperature environments ranging from -40°C to +85°C.

Feature Summary

• Advanced RISC architecture executing most instructions in a single clock cycle for high throughput
• Non-volatile memory segments supporting read-while-write operation and software security lock bits
• Integrated peripheral set including timers, PWM channels, and multiple serial communication interfaces
• Low-power design with five selectable sleep modes to minimize current consumption

Applications

• Industrial control systems
• Medical devices
• Automotive systems
• Consumer electronics
• Home automation systems

Procurement Notes

Verify that the specific part number matches the required PDIP-28 package configuration and industrial temperature rating. Confirm that the procurement source accepts components designated as NRND (Not Recommended for New Designs) for your project lifecycle. Ensure compatibility with existing PCB footprints and programming interfaces before finalizing orders.

Selection Notes

Select this component when a robust 8-bit AVR solution with sufficient flash memory and analog inputs is required for industrial or automotive applications. Consider the PDIP-28 package if through-hole mounting is necessary. Evaluate the 8MHz speed limit against processing requirements, noting that higher performance variants exist within the same family but may require different packaging or voltage specifications.

Part Context

The ATMEGA8L-8PI belongs to the Atmel AVR ATmega8 product line, which represents a high-performance, low-power 8-bit microcontroller family. This series is characterized by its efficient RISC core and extensive peripheral integration. The 'L' suffix indicates a low-voltage version optimized for operation down to 2.7V, while 'PI' denotes the PDIP package and industrial temperature grade.
