ATTINY25 in ATtiny Family
The ATTINY25 family consists of high-performance Microchip (formerly Atmel) 8-bit RISC-based microcontrollers designed for space-constrained applications. These AVR-core devices integrate 2KB of in-system programmable flash, 128B of SRAM, and 128B of EEPROM. They are favored by engineers for their extremely low power consumption and small footprints, typically available in 8-pin SOIC and PDIP packages. This family balances performance and power efficiency, making it a staple for simple control logic and peripheral management in industrial and consumer electronics.

| Part Number | Package | Temp Range | Stock |
|---|---|---|---|
| ATTINY25-20PU (Microchip Technology) | DIP-8 | -40degC ~ 85degC (.. | 2,852 |
| ATTINY25-20SU (Microchip Technology) | SOIC-8 | -40degC ~ 85degC (.. | 32,494 |

Variants within the ATTINY25 sub-family primarily differ by their packaging, temperature ratings, and compliance standards. While all share the same 2KB flash core, the 'PU' suffix indicates a through-hole PDIP package, whereas 'SU' and 'SN' denote surface-mount SOIC options. The 'SSNR' variant specifically targets safety-critical environments, offering Functional Safety (FuSa) support and higher-reliability testing compared to standard commercial or industrial grade versions.
