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.

Features

Incorporates a 1-bit Σ∆-type AD converter (two channels).

THD: −82dB, S/N ratio: 95dB (typ.)

Incorporates a 1-bit Σ∆-type DA converter (four channels).

THD: −85dB, S/N ratio: 100dB (typ.)

Weight: 1.57g (typ.)

A ±10-dB attenuator is built into the DA converter output block (two channels only)

Each port has a digital input/output (three lead-type)

A built-in self-boot function automatically sets the coefficients and register values at initialization.

: 1024 words × 32 bits

: 320 words × 16 bits

: 256 words × 16 bits

: 64 words × 16 bits

: 256 words × 24 bits

Data RAM

Operation speed

: 44ns (510-step (approx) operation per cycle at fs = 44.1 kHz)

Interface buffer RAM : 32 words × 16 bits

Incorporates data delay RAM.

Delay RAM

: 4096 words × 16 bits (64 kbits)

The microcontroller interface can be selected between Standard Transmission mode and I C bus mode.

CMOS silicon structure supports high speed.

The package is a 100-pin flat package.
