< Key features brought by LPC2109/2119/2129/01 devices >

  • 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 LPC2109/2119/2129/00 devices as well.
  • General purpose timers can operate as external event counters.

< Key features common for all devices>

  • 16/32-bit ARM7TDMI-S microcontroller in a tiny LQFP64 package.
  • 8/16 kB on-chip static RAM.
  • 64/128/256 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 while 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.
  • Two interconnected CAN interfaces (one for LPC2109) with advanced acceptance filters.
  • Four-channel 10-bit A/D converter with conversion time as low as 2.44 us.
  • Multiple serial interfaces including two UARTs (16C550), Fast I 2 C-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 us.
  • Vectored Interrupt Controller with configurable priorities and vector addresses.
  • Two 32-bit timers (with four capture and four compare channels), PWM unit (six outputs), Real-Time Clock (RTC) and watchdog.
  • 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 pct) with 5 V tolerant I/O pads.
