TPS-00344      LPC2138

Features and benefits

  • Fast GPIO ports enable port pin toggling up to 3.5 times faster than the original
  • LPC213x. They also allow for a port pin to be read at any time regardless of its
  •  
  • Dedicated result registers for ADC(s) reduce interrupt overhead.
  • UART0/1 include fractional baud rate generator, auto-bauding capabilities and

handshake flow-control fully implemented in hardware.

  • Additional BOD control enables further reduction of power consumption.
  • 16/32-bit ARM7TDMI-S microcontroller in a tiny LQFP64 or HVQFN64 package.
  •  8/16/32 kB of on-chip static RAM and 32/64/128/256/512 kB of on-chip flash program
  • memory. 128-bit wide interface/accelerator enables high-speed 60 MHz operation.
  •  In-System Programming/In-Application Programming (ISP/IAP) via on-chip bootloader

software. Single flash sector or full chip erase in 400 ms and programming of 256 B in

1 ms.

  •  EmbeddedICE RT and Embedded Trace interfaces offer real-time debugging with the
  • on-chip RealMonitor software and high-speed tracing of instruction execution.
  •  
  • One (LPC2131/32) or two (LPC2134/36/38) 8-channel 10-bit ADCs provide a total of

up to 16 analog inputs, with conversion times as low as 2.44s per channel.

  • Single 10-bit DAC provides variable analog output (LPC2132/34/36/38).
  • Two 32-bit timers/external event counters (with four capture and four compare

channels each), PWM unit (six outputs) and watchdog.

  • Low power Real-time clock with independent power and dedicated 32 kHz clock input.
  • Multiple serial interfaces including two UARTs (16C550), two Fast I2C-bus (400 kbit/s),
  • SPI and SSP with buffering and variable data length capabilities.
  • Vectored interrupt controller with configurable priorities and vector addresses.
  • Up to forty-seven 5 V tolerant general purpose I/O pins in tiny LQFP64 or HVQFN

package.

  • Up to nine edge or level sensitive external interrupt pins available.
  • 60 MHz maximum CPU clock available from programmable on-chip PLL with settling

time of 100 s.

  • On-chip integrated oscillator operates with external crystal in range of 1 MHz to

30 MHz and with external oscillator up to 50 MHz.

  • Power saving modes include Idle and Power-down.
  • Individual enable/disable of peripheral functions as well as peripheral clock scaling

down for additional power optimization.

  • Processor wake-up from Power-down mode via external interrupt or BOD.
  • Single power supply chip with POR and BOD circuits:
  • CPU operating voltage range of 3.0 V to 3.6 V (3.3 V ? 10 %) with 5 V tolerant I/O

pads
