4 / 8 page 4 of 8 ELM401 Electrical Characteristics Absolute Maximum Ratings Storage Temperature....................... -65°C to +150°C Ambient Temperature with Voltage Applied..................................-40°C to +85°C Voltage on VDD with respect to VSS............ 0 to +6.5V Voltage on any other pin with respect to VSS........................... -0.3V to (VDD + 0.3V) Note: Stresses beyond those listed here will likely damage this device. These values are given as a design guideline only. The ability to operate to these levels is neither inferred nor recommended. All values are for operation at 25°C and a 5V supply, unless otherwise noted. For further information, refer to note 1 below. Characteristic Minimum Typical Maximum Conditions Units Supply voltage, VDD 2.0 5.0 5.5 V VDD rate of rise 0.05 V/msec Average supply current, IDD 0.6 1.1 mA VDD = 5.0V Notes: 1. This integrated circuit is based on a Microchip Technology Inc. PIC12F5XX device. For more detailed specifications, please refer to the Microchip documentation (www.microchip.com). 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. The internal reset circuitry stops the ELM401 from doing anything during this period, so that the power supplies and oscillators have time to stabilize. During this time, all pins behave like inputs. 4. Typical only - the actual period varies with the amount of noise present in the input signal. 5. All filtering, delay, and output timing is based on an internal master oscillator. The frequency of this oscillator will vary with voltage and temperature. Values shown are typical maximums for 2.0V ≤ VDD ≤ 5.5V, and temperatures of -40°C to +85°C Output low current (sink) 10 mA mA 5.0 VOL = 0.25V see note 2 ELM401DSB Elm Electronics – Circuits for the Hobbyist www.elmelectronics.com A & B debounce period msec 5.5 VDD = 2.0V 0.2 0.3 mA VDD = 5.0V VDD = 3.0V VOL = 0.25V Output high current (source) 2.5 mA mA 1.7 VOH = 4.75V VDD = 5.0V VDD = 3.0V VOH = 2.75V see note 4 Power on reset time 9 msec see note 3 18 30 msec 50 Internal timing variation % 1 4 see note 5 Startup time delay |
