Frequently asked questions

What are the primary differences between the SPC560D30L1B4E0X and the SPC56AP54L5CEFAY?

The SPC560D30L1B4E0X is a 32-bit Power Architecture microcontroller from the SPC560D family, featuring 256 KB flash, 32 KB RAM, and a 64-pin LQFP package. The SPC56AP54L5CEFAY belongs to the SPC56AP family, offering 1.5 MB flash, 128 KB RAM, and a 144-pin LQFP package. The SPC56AP54L5CEFAY provides significantly higher memory density and more peripheral pins, while the SPC560D30L1B4E0X targets lower-complexity, cost-sensitive applications.

Are the SPC560D30L1B4E0X and SPC56AP54L5CEFAY pin-to-pin compatible?

No. The SPC560D30L1B4E0X uses a 64-pin LQFP package, while the SPC56AP54L5CEFAY uses a 144-pin LQFP package. The different pin counts and pinouts prevent direct PCB footprint compatibility without a redesign.

Can the SPC560D30L1B4E0X be used as a drop-in replacement for the SPC56AP54L5CEFAY?

No. Beyond package and pinout differences, the two devices differ in flash size (256 KB vs 1.5 MB), RAM (32 KB vs 128 KB), and peripheral set. A drop-in replacement is not possible; firmware and hardware must be revalidated against the target device.

Which device offers more embedded flash memory?

The SPC56AP54L5CEFAY offers 1.5 MB of embedded flash, whereas the SPC560D30L1B4E0X provides 256 KB. The SPC56AP54L5CEFAY is therefore better suited for applications requiring larger code storage.

Do both devices share the same Power Architecture core?

Yes. Both the SPC560D30L1B4E0X and the SPC56AP54L5CEFAY are based on the 32-bit Power Architecture e200z0 core, providing instruction set compatibility at the core level. However, peripheral and memory configurations differ significantly.

Which device is more suitable for space-constrained designs?

The SPC560D30L1B4E0X, with its 64-pin LQFP package, is more suitable for space-constrained designs. The SPC56AP54L5CEFAY requires a larger 144-pin LQFP footprint and offers more I/O and peripherals.

Are both devices qualified for automotive applications?

Both the SPC560D30L1B4E0X and the SPC56AP54L5CEFAY are part of STMicroelectronics' SPC5 family, which is designed for automotive and industrial applications. Specific qualification details such as AEC-Q100 grade should be verified in the respective device datasheets, as grades may differ between part numbers.
