Single-chip 16/32-bit microcontroller; 256 kB ISP/IAP flash with 10-bit ADC and CAN

• Fast GPIO ports enable port pin toggling up to 3.5 times faster than the original device. They also allow for a port pin to be read at any time regardless of its function.
• Dedicated result registers for ADC(s) reduce interrupt overhead. The ADC pads are 5 V tolerant when configured for digital I/O function(s).
• UART0/1 include fractional baud rate generator, auto-bauding capabilities and handshake flow-control fully implemented in hardware.
• Buffered SSP serial controller supporting SPI, 4-wire SSI, and Microwire formats.
• SPI programmable data length and leader mode enhancement.
• Diversified Code Read Protection (CRP) enables different security levels to be implemented. This feature is available in LPC2194/00 devices as well.
• General purpose timers can operate as external event counters.

2.2 Key features common for all devices

• 16/32-bit Arm7TDMI-S^™ microcontroller in a tiny LQFP64 package.
• 16 kB on-chip SRAM and 256 kB on-chip flash program memory. 128-bit wide interface/accelerator enables high speed 60 MHz operation.
• In-System Programming (ISP) and In-Application Programming (IAP) via on-chip bootloader software. Flash programming takes 1 ms per 512 B line. Single sector or full chip erase takes 400 ms.
• EmbeddedICE-RT and Embedded Trace interfaces offer real-time debugging with on-chip RealMonitor software as well as high speed real-time tracing of instruction execution.
