Microcomputer Product Guide

39
The TX39 Family of RISC microprocessors for embedded use was developed by Toshiba based on the R3000A archi-
tecture designed by MIPS Technologies, Inc. It is an original Toshiba 32-bit processor family. Using the TX39/H or the
high-speed TX39/H2, TX39/H3 as the CPU core for gate arrays and cell-based ICs, you can accomplish a high
level of integration in your system.

● Reduced code size and improved performance
■ Use of branch-likely instructions
■ Hardware interlock function
● Increased real-time capability
■ Cache lock function
● Real-time debugger system connection
■ Real-time debugging is possible while cache is on.
● Low power consumption modes
● Clock stop function
● TX39/H2: 0.25 µm process technology
● TX39/H3: 0.18 µm process technology
● Complete development environment
● R3000A architecture
● Internal operating frequency
TX39/H: 92 MHz, TX39/H2, H3: 133 MHz
● Built-in cache memory
● Non-blocking load function
■ The instructions which follow the instruction
currently being executed are executed while the
cache is being refilled.
● DSP function
■ 32-bit multiply-accumulate (MAC) operations take
only one clock cycle to execute.
