APPLICATION NOTE 93

Design Guidelines for Microcontrollers Incorporating NV RAM

By: Kevin Self

Abstract: This application note will help the user of the Dallas Semiconductor secure microcontroller and high-speed microcontroller improve reliability when implementing nonvolatile SRAM. This note is applicable to the Secure and High-Speed Secure Microcontroller families as well as the DS87C530 high-speed microcontroller. Out-of-tolerance voltage spikes, protecting I/O pins and negative power supply transients are discussed in this application note.
