Frequently Asked Questions
What is the maximum CPU clock frequency of TMS470R1A384PZ-T and how does it constrain real-time control loop rates?
The TMS470R1A384PZ-T runs at a maximum of 20 MHz, yielding approximately 20 MIPS on the ARM7TDMI pipeline, which supports 1 kHz control loops with margins for interrupt handling and peripheral tasks in body control module firmware.
Why does TMS470R1A384PZ-T require both 1.8 V and 3.3 V supply rails on the same board?
The ARM7TDMI core logic operates at 1.8 V to minimize dynamic power consumption, while the I/O ring uses 3.3 V to ensure signal-level compatibility with standard automotive sensors, CAN transceivers, and external Flash or SRAM devices on the bus.
How does the 384 KB Flash capacity of TMS470R1A384PZ-T compare to typical requirements for an automotive body control module?
A typical body control module firmware image for door lock, window lift, and interior lighting control ranges from 128 KB to 256 KB, so the 384 KB Flash on the TMS470R1A384PZ-T provides roughly 50% headroom for over-the-air update storage and bootloader code.
For PCB assembly verification, how does the boundary scan feature of TMS470R1A384PZ-T reduce test cost?
Boundary scan (JTAG IEEE 1149.1) allows a test system to clock digital patterns through all 100 pins without bed-of-nails fixtures, detecting solder opens and shorts across the LQFP footprint at a fraction of the cost of traditional in-circuit test probing.
