adv7170 datasheet:

-- ToddLarason - 25 May 2002 says the QED RMS5231 is a 64-bit MIPS-IV core, available in 150,200&250mhz versions, 2-8 pipeline stages to clock tick (325MIPS max), with single&double floating point. Any of Replay's marketing fluff give a clock speed ref?

NEC078f0034 info with datasheet and manual PDFs --

32k flash ROM, 1k RAM, uart, 3wire bus, i2c bus, 51 i/o ports, 10-bit 8channel adc

flash - MBM24f040c-90, 4m (512Kx8), plcc package -- for the datasheet (thanks Klaatu)

From a Conexant Doc about SmartDAA?:

Conexant's SmartDAA? technology (patent pending) eliminates the need for a costly analog transformer, relays, and opto-isolators typically used in discrete DAA (Data Access Arrangement) implementations The SmartDAA? architecture also simplifies product implementation by eliminating the need for country-specific board configurations enabling worldwide homologation of a single modem board design and a single bill of materials (BOM). The SmartDAA? system-powered DAA operates reliably without drawing power from the line, unlike line-powered DAAs which operate poorly when line current is insufficient due to long lines or poor line conditions. Enhanced features, such as monitoring of local extension status without going off-hook, are also supported. Incorporating Conexants proprietary Digital Isolation Barrier (DIB) design (patent pending) and other innovative DAA features, the SmartDAA? architecture simplifies application design, minimizes layout area, and reduces component cost.
