Features
General Features
- Conditional access descrambling DVB-pliant
- Stream demultiplexing (TS, PES, program and proprietary streams)
- Internal PR3001 32-bit RISC processor running at 40.5 MHz
- Low-power sleep modes supported across the chip
- prehensive driver software and development tool support
- Package: SQFP208. The following sections specify the Features in more detail, in the form of a feature matrix. External interfaces The SAA7214 supports the following external interfaces:
- Versatile pressed stream input at 108 Mbits/s
- A 16-bit microcontroller extension bus supporting DRAM, Flash, (E)PROM and external memory mapped
- I/O devices. It also supports a synchronous interface to municate with the integrated MPEG AVGD decoder SAA7215 at 40.5 Mbytes.
- an IEEE 1284 interface (Centronics) supporting master and slave modes. Usable as a general purpose port
- A dedicated interface to IEEE 1394 devices (such as Philips’ PDI 1394 chip set)
- Two UART (RS232) data ports with DMA capabilities (≤187.5 kbits/s) including hardware flow control Rx D, Tx D, RTS and CTS for modem support
- An elementary UART with DMA capabilities,(e.g. dedicated to front panel devices for instance)
- Two dedicated smart-card reader interfaces (ISO 7816 patible) with DMA capabilities
- Two I2C-bus master/slave transceivers supporting the standard (100 kbit/s) and fast (400 kbits/s) I2C-bus modes
- 32 general purpose, bidirectional I/O interface pins, the first 8 bits may also be used as interrupt inputs
- One PWM output (8-bit resolution)
- A GP/HS interface supporting stream recording through IEEE 1394 IC
- A JTAG interface for board test support. CPU related Features
