799 / 1075 page ![]() Section 25 Electrical Characteristics Rev. 3.00 Jan 18, 2006 page 771 of 1044 REJ09B0280-0300 Section 25 Electrical Characteristics 25.1 Absolute Maximum Ratings Table 25.1 lists the absolute maximum ratings. Table 25.1 Absolute Maximum Ratings Item Symbol Value Unit Power supply voltage V CC, VCL –0.3 to +4.3 V I/O buffer power supply voltage V CCB –0.3 to +7.0 V Input voltage (except ports 6, 7, and A) (include ports C and D for H8S/2169) V in –0.3 to V CC +0.3 V Input voltage (CIN input not selected for port 6) V in –0.3 to V CC +0.3 V Input voltage (CIN input not selected for port A) (include ports E to G for H8S/2169) V in –0.3 to V CCB +0.3 V Input voltage (CIN input selected for port 6) V in –0.3 V to lower of voltages V CC + 0.3 and AVCC + 0.3 V Input voltage (CIN input selected for port A) V in –0.3 V to lower of voltages V CCB + 0.3 and AVCC + 0.3 V Input voltage (port 7) V in –0.3 to AV CC + 0.3 V Reference supply voltage AV ref –0.3 to AV CC + 0.3 V Analog power supply voltage AV CC –0.3 to +4.3 V Analog input voltage V AN –0.3 to AV CC +0.3 V Operating temperature T opr –20 to +75 °C Operating temperature (flash memory programming/erasing) T opr –20 to +75 °C Storage temperature T stg –55 to +125 °C Caution: Permanent damage to the chip may result if absolute maximum ratings are exceeded. Ensure so that the impressed voltage does not exceed 4.3 V for pins for which the maximum rating is determined by the voltage on the V CC, AVCC, and VCL pins, or 7.0 V for pins for which the maximum rating is determined by V CCB. |
