Features
119-bump Ball Grid Array Package
• Fast access time: 8, 10, 12 ns
• CMOS low power operation: 260/210/180 mA at minimum
cycle time
• Single 3.3 V ± 0.3V power supply
• All inputs and outputs are TTL-compatible
• Fully static operation
• Industrial Temperature Option: –40 to 85°C
• Package
B: 14 mm x 22 mm, 119-bump, 1.27 mm pitch BGA
Description
The GS76024A is a high speed CMOS static RAM organized
as 262,144 words by 24 bits. Static design eliminates the need
for external clocks or timing strobes. Operating on a single
3.3 V power supply and all inputs and outputs are TTLcompatible. The GS76024A is available in a 119-bump BGA
package.
