QVGA TFT direct drive solution

Renesas Technology Europe announced the availability of a QVGA TFT direct drive solution based on the R32C/111 32-bit CISC MCU, which is part of Renesas' M16C microcontroller platform. The solution uses an R32C/111 StarterKit and a TFT-add-on-board developed by Segger. Offering embedded RAM and Flash as well as the standard peripherals, using the R32C MCU for the QVGA drive means there is no need for any additional external components, such as a display driver or external memory components. To scale peripheral, performance and RAM usage, the solution provides four different colour modes: Monochrome, 4 greyscale, 8 greyscale and 8 colour.

 The R32C/11x group has a maximum operating frequency of 50 MHz, which in combination with the enhanced CPU core architecture, delivers an overall processing performance of 42 DMIPS executing code from embedded flash at zero wait. It also incorporates an on-chip 32-bit multiplier, single-precision floating-point unit (FPU) and 32-bit enhanced barrel shifter for dramatically improved operation processing performance. The R32C/11x group includes a variety of on-chip peripheral functions, including timers and four DMA controller channels, as well as 16ch for PWM generation and measurement. Additional features include nine free scalable USART, 26 channels of 10-bit A/D converter, two 8-bit D/A converter channels and a CRC calculation circuit to reliability.

 Typical applications include the EPOS market, HVAC, energy and security panels and a broad range of industrial equipment, where external memory requirements make a 16-bit colour depth TFT solution too expensive. The combination of Segger's GUI "emWin" and RTOS "embOS" with the hardware from Renesas is the foundation for the development of an embedded product with QVGA-display-system.

 For implementation, Segger offers board support packages for embOS and emWin optimised for use with the R32C/11x group and TFT-add-on-board, as well as a complete trial package. The R32C/11x group comes in 64, 80, 100 and 144-pin packages scalable with on-chip Flash memory from 128kB to 1MB and RAM memory from 32kB to 63kB. The QVGA TFT direct drive demo set is available now.
