TDA7590

TDA7590 Digital signal processing IC for speech and audio applications Preliminary Data Features ■ 24-bit, fixed point, 120 MIPS DSP core www.DataSheet4U.com ■ Large on-board memory (128KW-24 bit) ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ Host access to internal RAM through expansion port Access to external RAM (16Mw) through expansion port Integrated stereo, 18-bit Sigma-DELTA A/D and 20-bit D/A converters Programmable CODEC sample rate up to 48KHz On-board PLL for core clock and converters External flash / SRAM memory bank management I2C and SCI serial interface for external control 2 ESSI interface JTAG interface Host interface 144-pin TQFP, 0.50mm pitch Automotive temperature range (from -40°C to +85°C) TQFP144 Nevertheless, the embedded CODECs bandwidth and the generic processing engine allow to proceed also full-band audio signals. The large amount of on-chip memory (128 Kwords), together with the 16 Mwords external memory addressable and the 32 general purpose I/O pins permit to build a DSP-system avoiding the usage of an additional Microcontroller. The presence of serial and parallel interfaces allows easy connection with external devices including CODECs, DSPs, Microprocessors and Personal Computers. In particular, the Debug/JTAG interface permits the on-chip emulation of the firmware developed. Further, the presence of the Timers and Watchdog Block makes TDA7590 suitable for PWM processing and allows the integration of a system Watchdog. Description The TDA7590 is a high perform...
