Übersicht
Description
- 128KB Flash, 16KB SRAM, and 4KB EEPROM for program and data storage.
- 32 I/O pins, supporting digital, analog (10-bit ADC), and communication interfaces (UART, SPI, I²C).
- 20MHz max clock speed (16MHz typical).
- 4 timers/counters, including PWM support.
- JTAG & ISP programming for debugging and firmware updates.
- 64-pin TQFP package (AU suffix).
Ideal for embedded systems requiring moderate processing, ample memory, and versatile I/O. Commonly used in automation, robotics, and DIY electronics.
Equivalent
- ATMEGA1284P-PU (DIP package)
- ATMEGA1284-AU (similar but with less flash memory)
- ATMEGA1284P-MU (QFN package)
- ATMEGA2564RFR2 (higher memory, wireless features)
- ATMEGA1281 (lower flash but pin-compatible)
For modern alternatives, consider ATmega1284PB (enhanced features) or SAM D21 (ARM-based, from Microchip). Always verify pinout and specs for compatibility.
