Dialog Semiconductor has collaborated with NEC Electronics to develop a design platform based on NEC Electronics' multimedia processor SoCs (system-on-chips) and Dialog's power management platform ICs. The design platform combines NEC Electronics EMMA Mobile 1 application processor with Dialog's DA9052 configurable PMIC (power management platform integrated circuit) to optimise performance and extend the battery life of portable devices. The combination gives connectivity to peripherals and modules for prototyping and iteration of application processor based system designs.
The EMMA Mobile 1 from NEC Electronics is a multimedia processor with enhanced functionalities and low power consumption. The EMMA Mobile 1 integrates various built-in interfaces such as SD card interface, USB, SPI, UART, PCM, IIC, and NTSC. The DA9052 integrates four DC/DC buck converters and 10 programmable LDOs on-chip. These LDOs can be connected to the DC/DC converters to improve system efficiency. Each output can be connected in series or parallel, adding flexibility. To further optimise the processor energy-per-task, dynamic voltage scaling can be used on up to five outputs and Dialog's SmartMirror dynamic biasing is implemented on all linear regulators.
