LPC2131/32/34/36/38

Single-chip 16/32-bit microcontrollers

 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 2.44

s 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.
