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 spec 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. Pullup resistor currents are not included in this figure.

4. The value of the internal pullup resistance is both supply and temperature dependent.

5. Times are approximate. LED output can only be reset by powering down.

6. Both the OutP and OutC outputs will be internally reset after this time. If a loop continues to remain open, it

will not retrigger an alarm. In contrast, the panic input will always retrigger an alarm if it remains closed.
