ATMEGA48PA in ATmega Family
The ATMEGA48PA is a high-performance, low-power 8-bit microcontroller family from Microchip Technology (formerly Atmel) based on the AVR RISC architecture. It is designed for applications where power efficiency and cost-effectiveness are paramount. Operating between 1.8V and 5.5V, it features 4KB of self-programming Flash, 512 bytes of SRAM, and 256 bytes of EEPROM. Its compact instruction set achieves throughputs approaching 1 MIPS per MHz, allowing for optimized power consumption versus processing speed.
Variants in This Sub-Family
Comparing specs that differ across variants.
| Part Number | Package | ADC/DAC | Stock |
|---|---|---|---|
| ATMEGA48PA-PU (Microchip Technology) | DIP-28 | A/D 6x10b | 984 |
| ATMEGA48PA-AU (Microchip Technology) | TQFP-32 | A/D 8x10b | 1,051 |
Variants within the ATMEGA48PA sub-family are primarily distinguished by their physical packaging and thermal ratings. The 'PU' suffix denotes a 28-pin PDIP package suitable for through-hole mounting and breadboarding, while the 'AU' and 'MU' suffixes indicate surface-mount TQFP and VQFN packages respectively. All variants maintain the same 4KB Flash and 20 MHz maximum frequency, ensuring code compatibility across different form factors.
