MCU Bridges USB And Ethernet

May 10, 2004

The 77.4-MHz 32-bit LH79524 and 16/32-bit LH79525 ARM720T-based microcontrollers (MCUs) represent Sharp Microelectronics' latest BlueStreak systems-on-a-chip. The flash-based MCUs support a touchscreen controller and a programmable LCD controller with a direct interface to STN, Color STN, TFT, and Sharp's Advanced-TFT panels. The chips feature four DMA channels, 16 kbytes of SRAM, an I²C interface, an I²S interface, timers, an SDRAM controller, and a watchdog timer. The LH79524 and LH79525 cost less than $12. Development kits start for less than $300, including C/C++ compilers and integrated development environments.

I earned a Bachelor of Electrical Engineering at the Georgia Institute of Technology and a Masters in Computer Science from Rutgers University. I still do a bit of programming using everything from C and C++ to Rust and Ada/SPARK. I do a bit of PHP programming for Drupal websites. I have posted a few Drupal modules.

I still get a hand on software and electronic hardware. Some of this can be found on our Kit Close-Up video series. You can also see me on many of our TechXchange Talk videos. I am interested in a range of projects from robotics to artificial intelligence.
