THE CHECKPOINT CHARLIE Honorable
Mention Winner. October 24, 2005
"The Philips ARM Design Contest 2005 is your introduction to Philips’s powerful LPC213x microcontroller family. These RISC MCUs are based on the high-performance 32-bit ARM7TDMI-S™ microprocessor, which features low-power consumption and 16-bit Thumb code for efficient and flexible designs. Other key features include a wide range of serial communications interfaces, on-chip 8/16/32-KB SRAM, 32-bit timers, single or dual 10-bit eight-channel ADCs, a 10-bit DAC, PWM channels, and 47 GPIO lines. These features coupled with a small footprint make the LPC2131/2132/2134/2136/2138 microcontrollers ideally suited for countless applications, such as access control, point of sale, communication gateways, voice recognition, industrial control, and medical systems. The Philips ARM Design Contest 2005 gave designers the opportunity to showcase their design skills as well as a myriad of applications made possible by the LPC213x microcontroller family. Participants from around the world accepted the challenge to build original, innovative projects. Each project’s core processor had to be an LPC213x, which are RISC microcontrollers based on the high-performance 32-bit ARM7TDMI-S microprocessor. Circuit Cellar Magazine, January 2006 Letter from Circuit Cellar to Carlos Cossio dated January 25, 2006: Dear Carlos, Congratulations on winning Honorable Mention in the Philips ARM Design Contest 2005! Enclosed please find your prize check for $500. Also enclosed is your framed Certificate in recognition of your accomplishment. I wanted to personally thank you for participating in the contest. Your hard work helped raise the level of competition. Your project was judged to be one of the best among a variety of high-quality designs. On behalf of Philips and Circuit Cellar, thank you again for participating in the LPC213x contest. I hope to see your name among the entrants to one of our other upcoming Circuit Cellar contests. Sincerely, Jennifer
Huber
