FAQ
What is the maximum operating frequency of the AT91SAM9G15-CU core?
The AT91SAM9G15-CU features an ARM926EJ-S™ core rated for operation at up to 400 MHz at 1.0 V ±10%. This frequency is guaranteed under specified thermal and voltage conditions per the DS60001781A datasheet. The AT91SAM9G15-CU achieves this performance with integrated 16 KB instruction and 16 KB data caches plus an MMU for efficient memory management in Linux-based deployments.
Does the AT91SAM9G15-CU support NAND Flash with hardware ECC?
Yes, the AT91SAM9G15-CU integrates a dedicated NAND Flash controller with programmable Multi-bit Error Correcting Code (PMECC) supporting up to 24 bits of correction per 512-byte sector. It also includes PMERRLOC for hardware-accelerated error location. This eliminates software ECC overhead and ensures robust data integrity in industrial logging and firmware update applications using MLC or SLC NAND.
What LCD interface capabilities does the AT91SAM9G15-CU provide?
The AT91SAM9G15-CU includes a full-featured LCD Controller (LCDC) supporting 24-bit RGB parallel output, 4-layer hardware overlay, alpha-blending, scaling, rotation, and color space conversion. It drives resolutions up to WXGA (1280×800) and supports both passive and active matrix panels. The AT91SAM9G15-CU's LCDC offloads GUI composition from the CPU, enabling smooth animation and multitasking in resource-constrained HMI designs.
How many USB interfaces does the AT91SAM9G15-CU support, and what speeds are available?
The AT91SAM9G15-CU supports three USB interfaces: one USB Device port (HS/FS) and two USB Host ports (each HS/FS), all with dedicated on-chip transceivers. This provides simultaneous High-Speed (480 Mbps) device and host operation, plus Full-Speed (12 Mbps) fallback. The AT91SAM9G15-CU's USB architecture enables concurrent use of USB peripherals (e.g., printer, flash drive) and USB device mode (e.g., CDC ACM for host debugging) without bandwidth sharing.
What is the package type and ball count of the AT91SAM9G15-CU?
The AT91SAM9G15-CU is packaged in a 217-ball BGA with 0.8 mm ball pitch and a 13 mm × 13 mm body size. It uses standard BGA assembly processes and is compatible with IPC-7351B footprint guidelines. The AT91SAM9G15-CU's pinout separates power domains (VDDCORE, VDDIOP, VDDANA, VDDNF, VDDUTMI) to simplify PCB layout and noise isolation in mixed-signal industrial applications.
