Sharp Microelectronics of the Americas has expanded its BlueStreak microcontroller line with the introduction of four 16/32-bit general-purpose MCUs that integrate the ARM7TDMI-S core to answer the needs of engineers designing industrial control, white goods, PDAs, and smart phones.

The new MCUs leverage the 32-bit ARM cores but require 16-bit designed circuit boards and memory devices to save on system design costs. Aside from 16-bit external addressing, the MCUs support CAN 2.0B connectivity and are capable of driving color (LH75401) or grayscale LCD (LH75400) displays. For applications not utilizing CAN, the LH75410 (grayscale LCD controller) and the LH75411 (color LCD controller) are available.

The color LCD controllers support a STN, CSTN, TFT, and HR-TFT LCD displays, as well as Sharp's Advanced TFT LCD that displays up to 4,096 colors.

Other key features include an 8-input 10-bit ADC with integrated touchscreen controller, 32KB of on-chip SRAM, a Vectored Interrupt Controller to speed the serving of interrupts, three UARTs, synchronous serial port, three 16-bit Counter/Timers with Capture, Compare and PWM logic, Watchdog Timer, and Low Voltage Detector. They operate at up to 50MHz at 3.3V over the industrial temperature range of -40C to 85C.
