LPC24xx Devices
Built for connectivity, these powerful yet cost-effective microcon-
trollers support 10/100 Ethernet, full-speed (12 Mbps) USB 2.0, USB
OTG, and CAN 2.0B. They have 512 KB of ISP/ IAP Flash, 98 KB of
SRAM, an external memory interface, 10-bit A/D and D/A converters,
an internal RC oscillator, and an SD memory-card interface on two
high-speed buses to eliminate communication bandwidth bottlenecks.
The LPC247x adds a QVGA LCD controller.
