ELM382
Absolute Maximum Ratings
Storage Temperature....................... -65°C to +150°C
Ambient Temperature with
Power Applied....................................-40°C to +85°C
Voltage on VDD with respect to VSS............ 0 to +7.5V
Voltage on any other pin with
respect to VSS........................... -0.6V to (VDD + 0.6V)
Note:
Stresses beyond those listed here will likely damage
the device. These values are given as a design
guideline only. The ability to operate to these levels
is neither inferred nor recommended.
Electrical Characteristics
All values are for operation at 25°C and a 5V supply, unless otherwise noted. For further information, refer to note 1 below.

Notes:
1. This integrated circuit is produced with a Microchip Technology Inc.’s PIC12C5XX as the core embedded
microcontroller. For further device specifications, and possibly clarification of those given, please refer to the
appropriate Microchip documentation.
2. This specification must be met in order to ensure that a correct power on reset occurs. It is quite easily
achieved using most common types of supplies, but may be violated if one uses a slowly varying supply
voltage, as may be obtained through direct connection to solar cells, or some charge pump circuits.
3. The value of the internal pullup resistance is both supply and temperature dependent.
4. This refers to the current flowing through the protection diodes when large voltages are applied to the clock
input (pin 5) through a current limiting resistance. Currents quoted are the maximum continuous.
