ATmega88V-15AT

Appendix B - ATmega88 Automotive Specification at 1.8V This document contains information specific to devices operating at voltage between 1.8V and 5.5V. Only deviations with standard operating characteristics are covered in this appendix, all other information can be found in the complete Automotive datasheet. The complete ATmega88 automotive datasheet can be found on www.atmel.com 8-bit Microcontroller with 8K Bytes In-System Programmable Flash ATmega88 Automotive Appendix B 7738C–AVR–11/09 1. Electrical Characteristics 1.1 Absolute Maximum Ratings Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress rating only and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.

Although each I/O port can sink more than the test conditions (0.5 mA at VCC = 1.8V) under steady state conditions (non-transient), the following must be observed: 1] The sum of all IOL, for ports B0 - B5, should not exceed 50 mA. If IOL exceeds the test condition, VOL may exceed the related specification. Pins are not guaranteed to sink current greater than the listed test condition. 4. Although each I/O port can source more than the test conditions (0.5 mA at VCC = 1.8V) under steady state conditions (non-transient), the following must be observed: 1] The sum of all IOH, for ports B0 - B5 should not exceed 50 mA. If IOH exceeds the test condition, VOH may exceed the related specification. Pins are not guaranteed to source current greater than the listed test condition. 5. Minimum VCC for Power-down is 2.5V. 2 ATmega88 Automotive 7738C–AVR–11/09 ATmega88 Automotive 1.2 DC Characteristics (Continued) Test Conditions IOL = 0.5 mA, VCC = 1.8V IOH = –0.5 mA, VCC = 1.8V VCC = 5.5V, pin low (absolute value) VCC = 5.5V, pin high (absolute value) Symbol VOL VOH IIL IIH RRST RPU Active 2 MHz, VCC = 1.8V Idle 2 MHz, VCC = 1.8V WDT disabled, VCC = 1.8V WDT enabled, VCC = 1.8V VCC = 2.7V Vin = VCC/2 VCC = 2.7V Vin = VCC/2 VCC = 2.7V ICC 30 20 0.8 0.2 0.2 4
