Freescale Semiconductor (www.freescale.com) has unveiled an ARM Cortex-M4 core based microcontroller (MCU) family that is ideal for single-chip, graphics LCD applications.
The Kinetis K70 family is suitable for applications requiring advanced connectivity, a graphic LCD user interface and security functionality, without the increased power consumption and cost related to multi-chip designs.
The high-performance Kinetis K70 family allow graphics LCD displays with its one MB of flash memory, integrated graphics LCD controller and 128KB of SCRAM that drive LCD panels at eight bit QVGA resolution without the complexity and costs of adding frame buffer memory and external program.
It also allows users to conveniently manage graphics processing’s performance demands, while simultaneously managing real-time communication, control and connectivity functions commonly required by HMI applications.
Freescale’s PEG development suite enables designer’s to create multi-layered, high-color-depth GUIs that operate tightly with the real-time operating system of applications. In fact, they can even move current PEG applications to the Kinetis K70 family from a different architecture.
To enhance computing throughput, the 120/150 MHz MCUs deliver increased cache responsibilities and up to 150 MHz CPU speed.
The floating point unit of MCUs extend the range of data-acquisition-intensive applications such as audio processing, motor drive and digital filtering by increasing system accuracy and reducing computation time.
Featuring dedicated motor control peripherals, the MCUs also offer BLDC, fast 16-bit ADCs with programmable delay lock and fault control for driving stepper, multiple timers and PMAC motors with sensorless or sensor algorithms.
