The SAM9G15 is a member of the Microchip | SMART series of 400 MHz ARM926EJ-S embedded microprocessor units. This MPU integrates a rich set of peripherals to support embedded industrial applications that require advanced user interfaces and high-speed communication. The SAM9G15 features a graphics LCD controller with 4-layer overlay and 2D acceleration (picture-in-picture, alpha-blending, scaling, rotation, color conversion), and a 10-bit ADC that supports 4-wire or 5-wire resistive touchscreen panels. Multiple communication interfaces include a soft modem supporting exclusively the Conexant SmartDAA line driver, HS USB Host and Device and FS USB Host with dedicated on-chip transceivers, two HS SDCard/SDIO/MMC interfaces, USARTs, SPIs, I2S and TWIs. The 10-layer bus matrix coupled with multiple DMA channels ensures uninterrupted data transfers with minimal processor overhead. The External Bus Interface incorporates controllers for 4-bank and 8-bank DDR2/LPDDR, SDRAM/LPSDRAM, static memories, as well as specific circuitry for MLC/SLC NAND Flash with integrated ECC up to 24 bits. The SAM9G15 is available in a 217-ball BGA package with 0.8 mm ball pitch.
