Key Differentiators
- Extended scan interface (Scan Interface 2) for rotary sensing (vs MSP430FR5988IPMR)
- AES hardware accelerator (vs MSP430FR5988IPMR)
- 128KB FRAM with unlimited write endurance (vs MSP430FR5987IPMR)
Design Notes
The MSP430FR5989IPMR operates from 1.8V to 3.6V. Use a low-dropout regulator (LDO) to provide a stable supply. Place a 100nF ceramic capacitor close to each VCC pin and a 10Β΅F bulk capacitor. The SVS (Supply Voltage Supervisor) should be configured to reset the MCU if the voltage drops below the minimum operating level.
For the 64-pin LQFP package, ensure proper grounding with a solid ground plane. Decouple the power supply with capacitors placed as close as possible to the VCC and VSS pins. For the crystal oscillator, place it close to the MCU and keep traces short to minimize parasitic capacitance.
Do not exceed the absolute maximum ratings. The FRAM memory has unlimited write endurance, but ensure the supply voltage is within the specified range during writes. The extended scan interface requires careful PCB layout to avoid noise. Use the Spy-Bi-Wire interface for debugging, and ensure the TEST pin is properly connected.
