Product Overview

The MC68711E20CFNE2 is a Microcontroller Unit with high-performance, on-chip peripherals. It operates from a single 5V (nominal) power supply. Very fast signal transitions occur on the MCU pins. The short rise and fall times place high, short duration current demands on the power supply. To prevent noise problems, provide good power supply bypassing at the MCU. Bypass capacitors have good high-frequency characteristics and situate them as close to the MCU as possible. Bypass requirements vary, depending on how heavily the MCU pins are loaded. A bidirectional control signal RESET acts as an input to initialize the MCU to a known start-up state. It also acts as an open-drain output to indicate that an internal failure has been detected in either the clock monitor or computer operating properly (COP) watchdog circuit. The CPU distinguishes between internal and external reset conditions by sensing whether the reset pin rises to logic 1 in <2 E-clock cycles after a reset has occurred.
