Preliminary specification
SAA7219
1 FEATURES
Conditional access descrambling Digital Video
Broadcasting (DVB) compliant and MULTI2 compliant
Stream demultiplexing: Transport Stream (TS),
Packetized Elementary Stream (PES), program and
proprietary streams
Internal 32-bit MIPS RISC based Central Processing
Unit (CPU) supporting MIPS16 instruction set and
running at 81 MHz
Low-power sleep modes supported across the chip
Comprehensive driver software and development tool
support
Package: SQFP208.
1.1 External interfaces
Versatile compressed stream input at 108 Mbits/s
A 32-bit microcontroller extension bus supporting
DRAM, SDRAM, Flash, (E)PROM and external memory
mapped I/O devices. It also supports a synchronous
interface to communicate with the integrated MPEG
Audio Video Graphics Decoder (AVGD) SAA7215 at
40.5 Mbytes.
An IEEE 1284 interface (Centronics) supporting master
and slave modes. Usable as a general purpose port.
An interface to IEEE 1394 devices (such as Philips
PDI 1394 chip-set)
Two UART (RS232) data ports with Direct Memory
Access (DMA) capabilities (187.5 kbits/s) including
hardware flow control signals RXD, TXD, RTS and CTS
for modem support
A Synchronous Serial Interface (SSI) to connect an
off-chip modem analog front-end
An elementary UART with DMA capabilities, 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 with DMA
capabilities, supporting the standard (100 kbit/s) and
fast (400 kbits/s) I2C-bus modes
32 general purpose, bidirectional I/O interface pins, 8 of
which may also be used as interrupt inputs
One Pulse Width Modulated (PWM) output with 8-bit
resolution
A General Purpose/High Speed (GP/HS) interface
supporting stream recording through IEEE 1394
interface IC
An extended JTAG interface for board test support.
1.2 CPU related features
The SAA7219 contains an embedded RISC CPU, which
incorporates the following features:
A 32-bit PR3930 core running at 81 MHz
8-kbyte, 2-way set associative instruction cache
4-kbyte, 4-way set associative data cache
A programmable Low-power mode, including wake-up
on interrupt
A memory management unit with 32 odd/even entries
and variable page sizes
Multiply/accumulate/divide unit with fast
multiply/accumulate for 16-bit and 32-bit operands
Two fully independent 24-bit timers and one 24-bit timer
including watchdog facilities
A real-time clock unit (active in Sleep mode)
Built-in software debug support unit as part of Extended
Enhanced JTAG debug interface
On-chip SRAM of 4 kbytes for storing code which needs
fast execution.
1.3 MPEG-2 systems features
Hardware based parsing of Transport Stream (TS),
Philips Semiconductors program and proprietary
software data streams. Maximum input rate is
108 Mbits/s.
A real-time descrambler consisting of 3 modules:
– A control word bank containing 14 pairs (odd, even)
of control words and a default control word
– The DVB descrambler core implementing the stream
decipher and block decipher algorithms
– The MULTI2 descrambler algorithm implementing
the CBC and OFB mode descrambling functions.
