TC9447F TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC9447F Single-Chip Audio Digital Signal Processor The TC9447F is a single-chip audio digital signal processor incorporating an AD/DA converter.

The built-in program memory (ROM) can contain a range of application programs for concert hall acoustic field simulation, for digital filters such as equalizers, and for dynamic range control.

In addition, the device includes 64kb of data delay RAM, making external RAM unnecessary.
