1MB SRAM MCUs Offer Rich Graphics In Portable Display Apps


NXP has announced new ARM Cortex-M4-based microcontrollers claimed to feature an embedded SRAM memory of 1MB, which is up to four times the SRAM offered in current MCUs, making them suitable to address the growing requirements of portable display applications.

New Kinetis K27/K28 ARM-based MCUs provide 1MB of embedded SRAM plus 2MB of Flash memory with lower system power to enable longer battery life and richer graphics in portable display applications.

The large SRAM enables users to install more software applications and apps on wearables, and other portable graphic display systems. The advanced integration also reduces system board footprint to enable small form factors in wearables, the firm noted.

“Embedded designers can now push the limits of integration to create more competitive products with NXP’s new Kinetis K27/K28 MCUs, which makes it possible for them to get the most out of their devices,” said Geoff Lees, senior vice president and general manager of the microcontroller business line at NXP. “Our new high-performance microcontrollers enable enhanced user interfaces and high-end customized apps while extending battery life, all of which are important when it comes to product differentiation for IoT devices, smart home products, wearables and industrial portable devices.”


The MCUs support a broad set of peripherals, including low-power peripherals to optimize battery life, dual USB controllers for high speed data transfer, external memory interfaces for additional program and data storage, and analog or other peripherals to process sensors in connected IoT devices.

The new devices are supported by a FRDM-K28F low-cost development platform that includes on-board discrete power management, accelerometer, QuadSPI serial flash, USB high-speed connector and full-speed USB OpenSDA. The FRDM-K28F board also supports optional add-on boards to add USB-Type C and Bluetooth low energy (BLE) connectivity, as well as a 5” LCD display board with capacitive touch from MikroElektronika for use cases requiring rich graphics.

Dr. Djordje Marinkovic, MikroElektronika Chief Business Development Officer, said, “As a valued NXP partner, our TFT Proto 5” CAPACITIVE board extension brings to life a sophisticated visual display enabled by NXP’s new Kinetis microcontrollers.”

Software tools to support development is NXP’s MCUXpresso SDK, which includes software enablement for NXP Microcontrollers, including system startup, peripheral drivers, USB and connectivity stacks, middleware, and real-time operating system (RTOS) kernels.

The new Kinetis K27/K28 MCU family will be commercially available in April 2017. For further details, view the full Press release.
