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.
