LPC2141/42/44/46/48

Single-chip 16-bit/32-bit microcontrollers

 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 (VIC) with configurable priorities and vector addresses.

 Up to 45 of 5 V tolerant fast general purpose I/O pins in a tiny LQFP64 package.

 Up to 21 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 an external crystal from 1 MHz to 25 MHz.

 Power saving modes include Idle and Power-down.

 Individual enable/disable of peripheral functions as well as peripheral clock scaling 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.

While the USB DMA is the primary user of the additional 8 kB RAM, this RAM is also accessible at any time by the CPU as a general

purpose RAM for data and code storage.
