Low cost, microcontroller-based embedded applications are particularly susceptible to performance degradation during ESD and EFT events. This sensitivity is due to process technologies employed where microcontrollers (MCU) implement transistor gate lengths which are capable of generating and responding to signals with rise times in the sub-nanosecond range (or an equivalent bandwidth of greater than 300 MHz). As a result, an MCU is quite capable of responding to ESD or EFT signals injected onto its pins.
