| TECHNICAL SPECIFICATIONS |
| Digital input/output |
| Digital type | CMOS |
| Number of I/O | 8 (DIO0 through DIO7) |
| Configuration | Independently configured for input or output.
Switch selectable output voltages: +5 V and +3.3 V |
| Power on conditions | Power on reset is Input mode except when bits are configured to operate as alarms. |
| Pull-up/pull-down configuration | All pins are connected to 47 kOhm resistors that share a common point accessible at Pin 22 of the device (PU/D). This pin is floating by default and is userconfigurable via external connection. For pull-up mode, connect this pin to Pin 21 (+5V). For pull-down mode, connect this pin to Pin 48 (GND). |
| Digital I/O transfer rate (software paced) | - Digital input – 50 port reads or single bit reads per second typical.
- Digital output – 100 port writes or single bit writes per second typical.
|
| Input high voltage (+5 V mode) | 4 V min, 5.5 V absolute max. |
| Input high voltage (+3.3 V mode) | 2.64 V min, 5.5 V absolute max. |
| Input low voltage (+5 V mode) | 1 V max., -0.3 V absolute min. |
| Input low voltage (+3.3 V mode) | 0.66 V max., -0.3 V absolute min. |
| Output low voltage (IOL = 2.5 mA) | 0.6 V max. |
| Output high voltage (IOH=-2.5 mA) | 4.3 V min. (+5 V mode), 2.7 V (+3.3 V mode) |
| Temperature alarms |
| Number of alarms | 8 (one per digital I/O line) |
| Alarm functionality | Each alarm controls its associated digital I/O line as an alarm output. The input to each alarm may be any of the analog temperature input channels. When an alarm is enabled, its associated I/O line is set to output and driven to the appropriate state determined by the alarm options and input temperature. The alarm configurations are stored in non-volatile memory and are loaded at power on. |
| Alarm input modes | - Alarm when input temperature > T1
- Alarm when input temperature > T1, reset alarm when input temperature goes below T2
- Alarm when input temperature < T1
- Alarm when input temperature < T1, reset alarm when input temperature goes above T2
- Alarm when input temperature is < T1 or > T2
Note: T1 and T2 may be independently set for each alarm. |
| Alarm output modes | - Disabled, digital I/O line may be used for normal operation
- Enabled, active high output (digital I/O line goes high when alarm condition is met)
- Enabled, active low output (digital I/O line goes low when alarm condition is met)
