ATMEGA8515-16PU AVR 8-bit Microcontroller 5.5V PDIP-40
The ATmega8515-16PU is a low-power, high-efficiency 8-bit AVR RISC microcontroller with 8 Kbytes of in-system programmable Flash, 512 bytes of EEPROM and 512 bytes of internal SRAM. It delivers near 1 MIPS per MHz (up to 16 MIPS at 16 MHz) and includes a rich peripheral set — timers/counters, three PWM channels, USART, SPI, analog comparator and an external memory interface — making it a versatile choice for control, data acquisition and communication tasks.
Designed for easy in-circuit programming and reliable operation in both hobby and commercial products, the ATmega8515 supports multiple sleep modes for low-power designs and provides 35 usable general-purpose I/O lines in the PDIP-40 package. Its on-chip watchdog, brown-out detection and optional bootloader area make firmware development and field upgrades straightforward.
Features:
- AVR enhanced RISC core — compact, single-cycle instructions.
- In-system programmable Flash with read-while-write support.
- On-chip EEPROM and SRAM for data storage.
- Multiple timers/counters with compare and capture modes.
- Hardware USART and SPI serial interfaces.
- Three PWM channels and analog comparator.
- Power-saving sleep modes (Idle, Power-down, Standby).
- Watchdog timer and brown-out detection.
- External memory interface for expanded address space.
- Robust packaging options (PDIP, TQFP, PLCC, QFN).
