ATMEGA8515L-8MJ

Microcontrollers Overview

The ATMEGA8515L-8MJ is a low-power CMOS 8-bit microcontroller based on the AVR enhanced RISC architecture. It features 8K bytes of In-System Programmable Flash, 512 bytes EEPROM, and 512 bytes SRAM. The device operates at speeds up to 8 MHz with a supply voltage range of 2.7V to 5.5V. It includes an external memory interface, 35 programmable I/O lines, two Timer/Counters, a Serial USART, SPI, and three PWM channels.

Microcontrollers Feature Summary

• Executes powerful instructions in a single clock cycle for high throughput efficiency
• Supports true Read-While-Write operation via optional boot code section
• Integrates an external memory interface for expanded address space
• Provides multiple power-saving modes including Idle, Power-down, and Standby

Microcontrollers Applications

• Embedded control systems requiring external memory expansion
• Industrial applications operating within industrial temperature ranges
• Low-power battery-operated devices utilizing sleep modes
• Systems requiring hardware serial communication via USART or SPI

Microcontrollers Procurement Notes

Verify the specific suffix 'MJ' against official Microchip ordering tables to confirm package type and temperature grade. Confirm RoHS compliance status as packaging alternatives may vary. Ensure compatibility with existing PCB footprints for the designated package format before procurement.

Microcontrollers Selection Notes

Select this variant for designs requiring the low-voltage 2.7V to 5.5V operating range and 8 MHz maximum frequency. Consider the availability of the external memory interface if larger program storage is needed beyond the internal 8KB Flash. Verify that the package dimensions match the target board layout constraints.

Microcontrollers Part Context

This component belongs to the ATmega8515 family, manufactured by Microchip Technology (formerly Atmel). It is backward compatible with the AT90S4414/8515 in most cases, though fuse bit locations differ. The 'L' suffix denotes the low-voltage version optimized for lower power consumption compared to standard voltage variants.
