NXP Semiconductors LPC23x ARM7™ based MCUs
NXP Semiconductors LPC23x ARM7™ based MCUs are built for connectivity, these powerful ARM7™ based microcontrollers (MCUs) support 10/100 Ethernet, full-speed (12Mbps) USB 2.0, and CAN 2.0B. The devices have up to 512KB of ISP/IAP Flash, up to 58KB of SRAM, 10-bit A/D, and D/A converters, as well as an IRC oscillator, and options for an SD memory card interface. The MCUs feature two AHB buses so high-bandwidth peripherals like Ethernet and USB can run simultaneously without impacting the main application. Applications include industrial control, POS systems, protocol conversion, building automation, and security systems.
