IDT7132SA Integrated Device Technology, IDT7132SA Datasheet - Page 11

• Manufacturer Part Number: IDT7132SA
• Description: High Speed 2k X 8 Dual Port Static Ram
• Manufacturer: Integrated Device Technology

AC Electrical Characteristics Over the
Operating Temperature and Supply Voltage Range
NOTES:
1. PLCC package only.
2. Port-to-port delay through RAM cells from the writing port to the reading port, refer to “Timing Waveform of Write with Port -to-Port Read and BUSY.”
3. To ensure that the earlier of the two ports wins.
4. t
5. To ensure that a write cycle is inhibited on port "B" during contention on port "A".
6. To ensure that a write cycle is completed on port "B" after contention on port "A".
7. 'X' in part numbers indicates power rating (SA or LA).
8. Industrial temperature: for specific speeds, packages and powers contact your sales office.
