Features

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 master mode enhancement.
Diversified Code Read Protection (CRP) enables different security levels to be implemented. This feature is available in LPC2114/2124/00 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 static RAM.
128/256 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 interface enables breakpoints and watch points. Interrupt service routines can continue to execute whilst the foreground task is debugged with the on-chip RealMonitor software.
Embedded Trace Macrocell (ETM) enables non-intrusive high speed real-time tracing of instruction execution.
Four-channel 10-bit ADC with conversion time as low as 2.44 µs.
Two 32-bit timers (with four capture and four compare channels), PWM unit (six outputs), Real-Time Clock (RTC) and watchdog.
Multiple serial interfaces including two UARTs (16C550), Fast I²C-bus (400 kbit/s) and two SPIs.
60 MHz maximum CPU clock available from programmable on-chip Phase-Locked Loop with settling time of 100 µs.
Vectored Interrupt Controller with configurable priorities and vector addresses.
Up to forty-six 5 V tolerant general purpose I/O pins. Up to nine edge or level sensitive external interrupt pins available.
On-chip crystal oscillator with an operating range of 1 MHz to 30 MHz.
Two low power modes, Idle and Power-down.
Processor wake-up from Power-down mode via external interrupt.
Individual enable/disable of peripheral functions for power optimization.
Dual power supply:
- CPU operating voltage range of 1.65 V to 1.95 V (1.8 V ± 0.15 V).
- I/O power supply range of 3.0 V to 3.6 V (3.3 V ± 10 %) with 5 V tolerant I/O pads. 16/32-bit ARM7TDMI-S processor.
