Tool/software:
Hello TI,
My name is Pedro Rodrigues, and I am a hardware design engineer working with electric steering actuators for industrial and automotive applications.
We currently use the TI processor TMS5700332BPZQQ1 in an industrial product that is in series production.
Recently, our EMS PCBA supplier informed us of an opportunity to use a processor from the same family with larger flash memory.
TMS5700332BPZQQ1 (currently used on our project) has 256kB , supports 45 GPIOs and 9 interrupt capabilities.
TMS5700432BPZQQ1R (proposed alternative) has 384kB of flash memory, supports 45 GPIOs, and provides 8 interrupt capabilities. Our supplier has indicated that this option is more cost-effective.
I'm contacting you to understand the risk impact of the move from TMS5700332BPZ to the large flash memory TMS5700432BPZ:
1. How can we identify which pins/interrupts are unavailable in the TMS5700432BPZ with 384kB?
2. Checking the datasheet seems that both versions use the 45 GPIOs. Are these GPIOs the same, so swapping the processor won't impact the GPIO availability?
3. Can TI clarify on the 8 versus 9 interrupt discrepancy (documentation, data sheet section about this, etc.).
Best regards,
Pedro Rodrigues
