SAMD20J in SAM Microcontrollers Family
The SAMD20J is a sub-family of Microchip Technology's SAM D20 series, designed around the 32-bit ARM Cortex-M0+ processor core. These microcontrollers provide a bridge between legacy 8-bit devices and high-performance 32-bit systems, focusing on low power consumption and ease of migration. Operating at up to 48MHz, the SAMD20J variant specifically offers the highest pin count in the series, making it ideal for systems requiring extensive peripheral connectivity and GPIO flexibility without the complexity of higher-end cores.
Variants in This Sub-Family
| Part Number | Difference | Stock |
|---|---|---|
| ATSAMD20J17A-AU (Microchip Technology) | 128KB Flash | 5,471 |
Variants within the SAMD20J sub-family are primarily distinguished by their non-volatile memory capacity and package types. Engineers can select between 16KB to 256KB of Flash and 2KB to 32KB of SRAM. While the 'J' suffix denotes the 64-pin count, specific part numbers like the J17 or J18 indicate the memory density. Packaging options include TQFP and QFN, catering to different thermal and board-space constraints.
