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.

■
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

■
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.
