Key Differentiators
- Higher flash memory (1.5 MB) compared to SPC560B50L3 (vs SPC560B50L3)
- Higher RAM (96 KB) compared to SPC560B50L3 (vs SPC560B50L3)
- Same package and pinout as SPC560B54L5 (vs SPC560B54L5)
Design Notes
Ensure proper decoupling of the VDD pins with 100nF ceramic capacitors placed close to each power pin. Additionally, use a 10uF bulk capacitor near the main power input. The supply voltage range is 3.3V to 5V, so verify the power supply design meets the requirements.
For the LQFP-100 package, ensure adequate thermal relief by using a solid ground plane and thermal vias under the exposed pad. Follow ST's layout guidelines for the crystal oscillator to minimize noise and ensure stable clock generation.
Do not exceed the maximum supply voltage of 5V. Ensure the reset pin is properly pulled up and has a capacitor for reliable power-on reset. When programming the flash, follow the recommended programming sequence to avoid corruption.
Compliance Information
