Audio SoC First To Exploit ARM Technology

Reportedly an industry first, the ChipCorder ISD9160 embarks as the first audio system-on-a-chip (SoC) to integrates a 32-bit ARM Cortex-M0 microcontroller (MCU) core running at 50 MHz. The device also enlists sophisticated power-management features, embedded flash and SRAM, real-time clock control, and multiple GPIOs. Audio interfaces include microphone, speaker driver, I2S, plus eight analog GPIOs.  Five power-saving modes that enable the device to operate under differing voltage allowances. Pricing for the ISD9160 is $2.50 each in volume. NUVOTON TECHNOLOGY CORP., San Jose, CA. (408) 943-6666.
