1 ATtiny634 8-bit AVR Microcontroller with 6K Bytes In-System Programmable Flash Appendix B ATtiny634 Specification at 5 C DATASHEET APPENDIX B This document contains information specific to devices operating at temperatures up to 5 C. Only deviations are covered in this appendix, all other information can be found in the complete datasheet. The complete datasheet can be found at

2 . Memories The EEPROM has an endurance of at least 5, write/erase cycles. EEPROM may not be programmed at supply voltages below V.

3 . Lock Bits, Fuse Bits and Device Signature Fuse bits may not be programmed at supply voltages below V. 3

Absolute Maximum Ratings* Storage Temperature C to +5 C Voltage on any Pin except RESET with respect to Ground V to V CC +.5V Voltage on RESET with respect to Ground-.5V to +3.V Operating Temperature C to +5 C *NOTICE: 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 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. Maximum Operating Voltage V DC Current per I/O Pin ma DC Current V CC and GND Pins ma 3.

Typical values at +5 C.. Max means the highest value where the pin is guaranteed to be read as low. 3. Min means the lowest value where the pin is guaranteed to be read as high. 4. Not tested in production. 5. Although each I/O port can sink more than the test conditions ( ma at V CC = 5V, 5 ma at V CC = 3V) under steady state conditions (non-transient), the sum of all I OL (for all ports) should not exceed ma. If I OL exceeds the test conditions, V OL may exceed the related specification. Pins are not guaranteed to sink current greater than the listed test condition. 6. Although each I/O port can source more than the test conditions ( ma at V CC = 5V, 5 ma at V CC = 3V) under steady state conditions (non-transient), the sum of all I OH (for all ports) should not exceed ma. If I OH exceeds the test condition, V OH may exceed the related specification. Pins are not guaranteed to source current greater than the listed test condition. 7. The RESET pin must tolerate high voltages when entering and operating in programming modes and, as a consequence, has a weak drive strength as compared to regular I/O pins. See Output Driver Strength on page. 8. These are test limits, which account for leakage currents of the test environment. Actual device leakage currents are lower. 9. Values are with external clock using methods described in Minimizing Power Consumption on page 39. Power Reduction is enabled (PRR = xff) and there is no I/O drive..bod Disabled. 5
