The LPC2129FBD64/01,15 is a 60 MHz single-chip 16/32-bit microcontroller with real-time emulation and embedded trace support. It is available in 64 pin LQFP package.

The 128-bit wide memory interface and a unique accelerator architecture enable 32-bit code execution at maximum clock rate. For critical code size applications, the alternative 16-bit Thumb mode reduces code by more than 30 % with minimal performance penalty.


  • 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.
  • 16/32-bit ARM7TDMI-S microcontroller in a tiny LQFP64 package.
  • 8/16 kB on-chip SRAM
  • 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 µs.
  • Multiple serial interfaces including two UARTs (16C550), Fast I2C-bus (400 kbit/s) and two SPIs
