Kirchheim, Germany — Dialog Semiconductor plc is collaborating with NEC Electronics Corp. to develop a design platform based on NEC Electronics’ multimedia processor system-on-chips (SoCs) and Dialog’s power management platform ICs, which is optimized for audio/video portable devices and smart phones.
The design platform combines NEC Electronics’ EMMA Mobile 1 application processor with Dialog’s DA9052 configurable power management platform integrated circuit (PMIC) to optimize 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.
NEC’s EMMA Mobile 1 is a next-generation multimedia processor with enhanced functionality and low-power consumption. The processor integrates various built-in interfaces such as a 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 for additional flexibility.
To further optimize 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.
