DS07-16802-2ET1 Errata This errata sheet is for MB91314A Series Data Sheet Rev.2 (DS07-16802-2E) FR60 32-BIT MICROCONTROLLER MB91314A Series DATA SHEET Date 2011/ 8/4 Page 19 Item ■HANDLING DEVICES 2011.8.4 Description ・Notes on the turning on/off VDDI pin (1.8 V internal power supply) and VDDE pin (3.3 V external pin power supply) was added as indicated by the shading below. ・Notes on the turning on/off VDDI pin (1.8 V internal power supply) and VDDE pin (3.3 V external pin power supply) Do not apply only VDDE pin (external) voltage continuously (more than one minute) with VDDI pin (internal)disconnected as it adversely affects the reliability of the LSI. When VDDE pin (external) returns from the OFF state to the ON state, the circuit may fail to hold its internal state, for example, due to power supply noise. Power on VDD pin (internal) → Analog → VDDE pin (external) → signal Power off Signal → VDDE pin (external) → Analog → VDDI pin (internal) When the power is turned on, the output pin may remain unstable until the internal power supply becomes stable. There is no problem for turning on and off the power (VDDI/VDDE/analog) simultaneously. [mcu_doc:985] 1/1
