1. Description
The SAM9G15, based on the ARM926EJ-S processor, runs at 400 MHz and integrates a rich
set of peripherals to support embedded industrial applications that require advanced user inter-
faces and high-speed communication.
The SAM9G15 features a graphics LCD controller with 4-layer overlay and 2D acceleration (pic-
ture-in-picture, alpha-blending, scaling, rotation, color conversion), and a 10-bit ADC that
supports 4/5-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 trans-
fers with minimal processor overhead.
The External Bus Interface incorporates controllers offering support for 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 0.8mm ball pitch.
