SAA5070 Description

Short technical summary and product information.

The SAA5070 from NXP Semiconductors is a complex microcomputer/microprocessor peripheral integrated circuit. It is built using N-channel MOS technology and is intended for use in wired data communication systems, particularly viewdata applications.

 

Key features include a microcomputer/microprocessor interface, modem capabilities supporting both 1200/75 and 1200/1200 baud rates. It also incorporates a tape recorder modem compliant with the modified 'Kansas City' standard at 1300 baud. The device includes line and tape recorder UARTs with software parity control, autodialler functionality for British Post Office and Continental requirements, IBUS receivers and transmitters, timer circuits with 60-second and 1.5-second time-outs, and general input/output ports.

 

This IC provides provision for connecting external modems via a V24 interface. It operates within a supply voltage of 5V and a supply current of 100mA typical. The operating ambient temperature range is -20°C to +70°C. The SAA5070 is supplied in a 40-lead plastic package (SOT-129).

 

This component is suitable for applications requiring integrated modem and communication control functions within data systems.
