The LPC2131/32/34/36/38 microcontrollers are based on a 16/32-bit\r\n\
ARM7TDMI-S CPUwith real-time emulation and embedded trace support,\r\n\
that combine the microcontrollerwith 32kB, 64kB, 128kB, 256kB and\r\n\
512 kB of embedded high-speed ?ash memory. A128-bit wide memory\r\n\
interface and a unique accelerator architecture enable 32-bit\r\n\
codeexecutionatmaximumclockrate.Forcriticalcodesizeapplications,\r\n\
thealternative16-bitThumb mode reduces code by more than 30% with\r\n\
minimal performance penalty.Due to their tiny size and low power\r\n\
consumption, these microcontrollers are ideal forapplications where\r\n\
miniaturization is a key requirement, such as access control\r\n\
andpoint-of-sale. With a wide range of serial communications\r\n\
interfaces and on-chip SRAMoptions of 8kB, 16kB, and 32kB, they\r\n\
are very well suited for communication gatewaysand protocol\r\n\
converters, soft modems, voice recognition and low-end imaging,\r\n\
providingboth large buffer size and high processing power. Various\r\n\
32-bit timers, single or dual10-bit 8-channel ADC(s), 10-bit DAC,\r\n\
PWM channels and 47 GPIO lines with up to nineedge or level sensitive\r\n\
external interrupt pins make these microcontrollers particularlysuitablev\r\n\
for industrial control and medical systems.\r\n\
