TDA7550R_01 Datasheet - STMicroelectronics

DESCRIPTION
The TDA7550R is a high performances, fully programmable 24-bit, 45 MIPS Digital Signal Proces sor (DSP), designed to support several speech and audio applications, as Automatic Speech
Recognition, Speech Synthesis, Speaker Verification, Echo and Noise Cancellation. Software for these applications is licenced by Lernout & Hauspie and BIT Innovation Technologies. It offers an effective solution for this kind of applications because of the A/D and D/A converters and the big amount of memory integrated on chip.

■ 24-BIT, FIXED POINT, 45 MIPS DSP CORE
■ LARGE ON-BOARD PROGRAM RAM AND DATA RAM (16Kw-24 BIT DATA RAM AND 16Kw-24 BIT PROGRAM RAM)
■ INTEGRATED STEREO, 16-BIT SIGMA DELTA A/D AND D/A CONVERTERS
■ 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
■ I2C OR SPI SERIAL INTERFACE FOR EXTERNAL CONTROL
■ 80-PIN TQFP, 0.65 mm PITCH
■ AUTOMOTIVE GRADE (FROM -40° C to +85°C)
