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
- 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
- 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
