MK5027 General Description

The SGS-THOMSON Signalling System #7 Sig nalling Link Controller (MK5027) is a VLSI semiconductor device which provides a complete link control function conforming to the 1988 CCITT version of SS7. This includes frame formatting, transparency (so called "bit-stufling"), error recovery by two types of retransmission, error monitoring, sequence number control, link status control, and FISU generation. One of the outstanding features of the MK5027 is its buffer management which includes on-chip DMA. This feature allows users to handlq multiple packets of receive and transmit data at a time. (A conventional data linkcontrol chip plus a separate DMA chip would handle data for only a single block at a time.) The MK5027 may be used with any of several popular 16 and 8 bit microprocessors, such as 68000, 6800, Z8000, Z80, LSI-11, 8086, 8088, 8080, etc.

MK5027 Maximum Ratings

Temperature under Bias	25°C to +100
Storage Temperature	65°C to +150
Voltage on Any Pin with Respect to Ground	0.5V to VCC +0.5V
Power Dissipation	0.50W

Stresses above those listed under "Absolute Maximum Ratings" may cause permanent damage to the above device. his is a stress rating only and functional operation of the device at these or any other condition above those indicated in the operational ections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affectdevice reliability.
