Hi,

our company is considering replacing the aging F28M35H52C MCU,

is there a pin to pin alternative which is more capable, specifically with the memory side...

thanks

Peter,

Unfortunately, we do not have a p2p alternative for F28M35. We have the TMS320F28388D device, which is functionally equivalent, but with significant enhancements compared to the M35 device.

Hi Hareesh and Peter,

I am in the same situation, considering to eventually move away from the concerto. Unfortunately, porting to the newer TMS320F28388D seems to have little cost benefit to us at this stage. It would trigger a lot of software changes. For example, related to bootup and firmware updates. One major software porting issue is that the ARM processor is no longer the "master" in the newer device.

Christian,

I understand your predicament. However, the 28388D device is the only upgrade option for applications looking for a “Concerto-like” device. i.e. a device with a 28x core and an ARM core.

Thanks you for the answer,

1. For future decisions, is there a way for me to check existing pin to pin alternative MCU's, maybe some database?

2. Is there a way for me to predict which MCU would have pin to pin successors when choosing an MCU?

thanks

it seems both the CPU's on the 28388D are C2000,

no arm based CPUs on the 28388D ...

No. No such database exists.

No. While we make an earnest effort to maintain pin-compatibility, it is not always possible. This is because, the new devices may use a different package which may be warranted by addition/subtraction of peripherals, difference in power consumption etc.

I am afraid you are mistaken. 28388D does have a Arm® Cortex®-M4 processor.
