1 / 12 page 24-BIT, FIXED POINT, 50 MIPS DSP CORE LARGE ON-BOARD PROGRAM ROM AND DATA RAM (UP TO 16Kw ROM/RAM AND 16Kw RAM) INTEGRATED STEREO A/D AND D/A, 16-BIT SIGMA-DELTA PROGRAMMABLE CODEC SAMPLE RATE FROM 4 TO 48 kHz ON-BOARD PLL FOR CORE CLOCK AND CONVERTERS MANAGEMENT OF EXTERNAL FLASH/SRAM/DRAM MEMORY BANK I 2C OR SPI SERIAL INTERFACE FOR EX- TERNAL CONTROL 80-PIN TQFP, 0.65 mm PITCH AUTOMOTIVE GRADE (FROM -40° C to +85°C) DESCRIPTION The TDA755X family is a high performances, fully programmable 24-bit, 50 MIPS Digital Signal Processor (DSP), designed to support several speech and audio applications, as Automatic Speech Recognition, Speech Synthesis, Speaker Verification, Echo and Noise Cancellation. Soft- ware for these applications is licenced by Lernout & Hauspie and NCTI. It offers an effective solution for this kind of appli- cations because of the A/D and D/A converters and the big amount of memory integrated on chip. This is preliminary information on a new product now in development. Details are subject to change without notice.
