LPC2141/42/44/46/48
Single-chip 16-bit/32-bit microcontrollers
s Multiple serial interfaces including two UARTs (16C550), two Fast I2C-bus (400 kbit/s),
SPI and SSP with buffering and variable data length capabilities.
s Vectored Interrupt Controller (VIC) with configurable priorities and vector addresses.
s Up to 45 of 5 V tolerant fast general purpose I/O pins in a tiny LQFP64 package.
s Up to 21 external interrupt pins available.
s 60 MHz maximum CPU clock available from programmable on-chip PLL with settling
time of 100
µs.
s On-chip integrated oscillator operates with an external crystal from 1 MHz to 25 MHz.
s Power saving modes include Idle and Power-down.
s Individual enable/disable of peripheral functions as well as peripheral clock scaling for
additional power optimization.
s Processor wake-up from Power-down mode via external interrupt or BOD.
s Single power supply chip with POR and BOD circuits:
x CPU operating voltage range of 3.0 V to 3.6 V (3.3 V
± 10 %) with 5 V tolerant I/O
pads.
