LPC23xx Devices

Built for connectivity, these powerful yet cost-effective microcon-

trollers support 10/100 Ethernet, full-speed (12 Mbps) USB 2.0, and

CAN 2.0B. They have up to 512 KB of ISP/IAP Flash, up to 98 KB of

SRAM, 10-bit A/D and D/A converters, an IRC oscillator, and options

for an SD memory-card interface.
