概要
Description
- 2KB Flash memory
- 128B SRAM & 128B EEPROM
- 12 I/O pins (including 8-bit and 4-bit ports)
- 10-bit ADC, PWM, and hardware USI for SPI/I²C communication
- 1.8–5.5V operating voltage, making it suitable for battery-powered applications
- Up to 20MHz clock speed (with external oscillator)
Packaged in a 14-pin SOIC, it’s ideal for compact, cost-sensitive designs like sensors, wearables, or simple control systems. Its sleep modes enhance energy efficiency.
Programming is supported via SPI using tools like AVR ISP or Arduino (with cores like ATTinyCore).
Key strengths: Small size, low cost, and versatility for basic embedded tasks.
Equivalent
- ATTINY44A-SSU: Similar but with more flash (4KB) and I/O pins (12).
- ATTINY25V-10SSU: Lower voltage (1.8-5.5V), smaller flash (2KB), but same package.
- ATTINY84A-SSU: Higher flash (8KB) and I/O (12 pins).
- ATTINY261A-SSU: More flash (2KB) and I/O (18 pins).
All are 8-bit AVR microcontrollers in SSOP-14 package, offering comparable features. Choose based on required memory, I/O, or voltage range.
