375MHz and 450MHz ARM926EJ-S CPU options (both with MMU)
32KB L1 cache, 128KB L2, and 64KB ROM
NAND, flash, and NOR support
MMC/SD memory interface Programmable Real-time Unit (PRU) for configurable I/O and ARM9 offload
USB 2.0 on-the-go (OTG) with integrated PHY
I2C, SPI, UART interfaces (number of interfaces may vary depending on model)
PWM, eCAP, McASP interfaces (numbers may vary)
64-bit timers (numbers may vary)
Core voltage: 1.2 V (375MHz) or 1.3 V (450MHz) I/O supply (AM17x only): 1.8 V, 3.3 V
Operating temperature: 0 to 90 deg. C (32 to 194 deg. F); -40 to 90 deg. C; -40 to 105 deg.
最便宜的一款只有6.XX美金,高速的USB接口,100M网络，NAND,等，
关键是QFP176封装,两层PCB就可以了. |
