GT64120-B-4

The GT64120-B-4 is designed as one kind of system controllers for RC4650/4700/5000 and RM526x/527x/7000 which provides a single-chip solution for designers building systems with any of the high performance 64-bit bus MIPS CPUs. The architecture of it supports several system implementations for different applications and cost/performance points. GT64120-B-4 is possible to design a powerful system with minimal glue logic, or add commodity logic for differentiated system architectures that attain higher performance.

GT64120-B-4 has many features. (1)Integrated system controller with PCI interface for high performance embedded control applications. (2)Supports all 64-bit bus MIPs CPUs. (3)75MHz CPU bus frequency. (4)Supports up t four GT-64120 devices on the same sysAD bus. (5)64 byte CPU write posting buffer. (6)CPU address remapping to resources. (7)256KB or 512KB zero-wait state secondary cache support. And so on.

Some absolute maximum ratings of GT64120-B-4 have been concluded into several points as follow. (1)Its supply voltage would be min -0.3V and max 4.0V. (2)Its input voltage would be min -0.3V and max 5.5V. (3)Its output voltage would be min -0.3V and max 5.5V. (4)Its output current would be max 24mA.
