ABSOLUTE MAXIMUM RATINGS
RECOMMENDED OPERATING CONDITIONS
(TA = -40°C to +85°C)
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
Voltage on VCC, SDA, and SCL Pins
Relative to Ground.............................................-0.5V to +6.0V
Voltage on A0, A1, A2, TCK, TMS, TDI, and I/O_n [n = 0 to 8]
Relative to Ground ...................................-0.5V to VCC + 0.5V,
not to exceed +6.0V.
Operating Temperature Range ...........................-40°C to +85°C
EEPROM Programming Temperature Range .........0°C to +70°C
Storage Temperature Range .............................-55°C to +125°C
Soldering Temperature .....................See IPC/JEDEC J-STD-020
