"The GESBC-9G20 (above and farther below) appears to be a
follow-on to Glomation's GESBC-9260 SBC (pictured at right), which
shipped last August equipped with Atmel's earlier, 200MHz
AT91SAM9260 processor. Atmel's newer AT91SAM9G20, announced in May
2008, is clocked to 400MHz and offers 32KB each of data and
instruction cache, or twice the clock speed and four times the
cache of its predecessor. It also doubles internal ROM to 64KB,
doubles internal SRAM to 16KB, and consumes half the power of the
earlier SoC, for a maximum of 80mW.
"The GESBC-9G20 backs up the AT91SAM9G20 with a choice of 64MB
or 128MB of 100MHz SDRAM, as well as flash storage ranging from
256MB to 1GB, all soldered on, says Glomation. Other real-world
connectors include dual USB host ports and a USB device port, plus
a nine-pin connector for one of the board's three RS-232
ports."
