LPC2XXX series chip is a chip of NXP (NXP)'s a very important, is the world's smallest 32-bit ARM microcontroller. LPC2XXX series microprocessor operating frequency of 60MHz, with based on ARMTDMI kernel 32-bit RISC. LPC2000 of peripheral interfaces, including UART, SPI, I2C, CAN, the ADC, the PWM, the RTC.

This series of products is very broad, there are over 80 models, concrete can be divided into series LPC2100, LPC2200 series, the LPC2300 series, the LPC2400 series, LPC2800 and LPC2900 series

This series of microcontrollers LPC2114/2124/2119/2129/2194 LPC2210/2212/2214, LPC2290 / 2292/2294 with the on-chip memory to load the module to achieve a "zero wait for access to high-speed flash memory functions, improve the efficiency of the instruction execution . Provide enhanced communications capabilities and on-chip code protection mechanisms on the basis of high-performance, low power consumption. Built a wide range of serial communication interface, they are also well suited for communication gateways, protocol converters and embedded soft modems.

Our company when the chips come out from this type of specialized engineers concerned about such chips, behind the company began to receive the decryption type of chip demand, the long period of time our company need to find groping decrypt the breakthrough after a few failed finally found a hardware type of chip technology, but the high value of customers' products, the hardware solution needs to chip destruction, and often hard to solve a chip solution, because of the different chip inside the crystal, so these chips decrypt the success rate is not high. The opening piece, need to find a dedicated chip plant to help jumper, the cost is very high, the price is also very expensive.

With the popularity of such chips is getting higher and higher customer demand for continuous improvement, our company see this chip decryption with a very big market in chip research, in order to improve the competitiveness of the Division I, we are particularly external and senior engineer of the package to jointly overcome these chips, we want to achieve the target is soft solutions such chips, and finally, the exciting moment arrived. April 20, 2011, we finally decrypt the LPC2119 this film is successful, of course, soft solution of a chip is just the first step in the Great Wall, of course, is that this step is also a major step, it represents the target is getting closer, with the continuous efforts and pursuit of the East leaders to continue the strict requirements and continuous learning progress, and finally more and more LPC2XXX series chips we decrypt out behind the engineer for the decryption chip made a decrypt LPC2XXX method, has made remarkable achievements and breakthroughs. For many customers it is very good news, soft solution, the first chip is not destroyed, the original film can be refunded to the customer, the more critical is to greatly reduce the cost and success rate is very high. Here we specialize in a form to make a comparison of two methods.
