Description



Features:

Incorporates a two-channel microphone amp with auto level control (ALC), AD/DA converter, delay memory, and electronic volume controllers.
Incorporates a 32-kHz sampling, 12-bit successive comparison AD/DA converter.
Incorporates a delay memory (16-Kbit DRAM) which enables 128-ms (typ.) delay.
 Microphone and echo levels are controlled by built-in volume
controllers. They are controlled either by DC voltage or
controlled in serial by the MCU.
TC9455F/N: Supports I2C bus interface
TC9488F/N: Supports three-lead interface
The system clock is generated by the CR oscillator circuit.
The echo feedback amount is configured using analog circuits. The feedback level can be freely set.
The IC comes in 30-pin flat package or 24-pin shrink DIP.
