ATMEGA168PA in ATmega Family
The ATMEGA168PA is a high-performance, low-power 8-bit microcontroller family from Microchip Technology, based on the enhanced RISC AVR architecture. It features 16KB of self-programming flash memory, 1KB SRAM, and 512 bytes of EEPROM. Designed for high efficiency, it executes powerful instructions in a single clock cycle, allowing the system to optimize power consumption versus processing speed. It is a staple in the embedded industry for low-power sensing and general-purpose control applications where reliability is paramount.
Variants in This Sub-Family
Comparing specs that differ across variants.
| Part Number | Package | ADC/DAC | Stock |
|---|---|---|---|
| ATMEGA168PA-AU (Microchip Technology) | TQFP-32 | A/D 8x10b | 19,021 |
| ATMEGA168PA-PU (Microchip Technology) | DIP-28 | A/D 6x10b | 425 |
Variants within the ATMEGA168PA sub-family primarily differ by physical packaging and thermal rating. The AU variant offers a 32-lead TQFP package for surface-mount high-density layouts, while the PU variant utilizes a 28-pin PDIP for through-hole mounting or prototyping. Some suffixes also denote tape-and-reel options or extended temperature ranges suitable for automotive or industrial environments, though the internal silicon die and peripheral set remain functionally identical.
