Overview
INTEGRATED CIRCUITS DATA SHEET SAA7214 Transport MPEG2 source decoder Preliminary specification Supersedes data of 1999 Mar 16 File under Integrated Circuits, IC02 2001 Mar 28 Philips Semiconductors Preliminary specification Transport MPEG2 source decoder FEATURES General features • Conditional access descrambling DVB-compliant • 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 • Comprehensive 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 compressed 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 communicate 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 RxD, TxD, 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 compatible) 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.
