General description：

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

Features and benefits：

① Enhancements brought by LPC213x/01 devices

 Fast GPIO ports enable port pin toggling up to 3.5 times faster than the originalLPC213x. They also allow for a port pin to be read at any time regardless of itsfunction.

 Dedicated result registers for ADC(s) reduce interrupt overhead.

 UART0/1 include fractional baud rate generator, auto-bauding capabilities andhandshake flow-control fully implemented in hardware.

 Additional BOD control enables further reduction of power consumption.
