Nuvoton Technology Corp. introduced the ChipCorder ISD9160 system-on-a-chip (SoC) device, which features a 32-bit ARM Cortex-M0 microcontroller core.
The ISD9160 is designed to optimize low-power audio recording and playback in industrial applications, such as portable medical devices, security systems, and public transit vehicles, as well as consumer designs, including wireless audio, capacitive button sensing for touch panels, home appliances, toys, and novelty items.
With a Cortex-M0 core running at up to 50MHz, power-management features, embedded Flash and SRAM memory, real-time clock (RTC) control, and multiple general-purpose IOs (GPIOs), the ISD9160 enables designers to develop systems and individual products capable of delivering clear, reliable, easily managed audio recording and playback. In addition, the chip’s highly integrated architecture eliminates the need for various periphery chips.
ARM Cortex-M0 core (up to 50MHz)
Power management (wide voltage range; four levels of power control; sub-µA deep-power-down, wake-up, standby with RTC <6µA, processor sleep modes)
On-chip memory (145K Flash, 12K SRAM)
Clock control (48/32MHz built-in trimmed and ultra-low power 10kHzoscillators, 32kHz RTC crystal interface)
ISD9160 has configurable on board flash memory which can be configured as data memory and be used for audio storage.
Out of 145 KB onchip flash memory , 4 KB is reserved for LDROM rest of 141 KB can be shared between APROM and data ROM.
Having everything on a single chip is an improvement and $2.50 is a nice price point. Is there data flash for storing audio data or do you need an external chip for that? The SPI/SD interface seems to indicate you need an external device...
