Instructions for Using the DS1286
Power Supply:
- Ensure the supply voltage (VCC) is within the specified range of 4.75V to 5.25V.
- The device operates with a typical active current of 30μA and a standby current of 1μA.
Temperature Considerations:
- The operating temperature range is from -40°C to 85°C.
- The storage temperature range is from -65°C to 150°C.
Input/Output Levels:
- Output high voltage (VOH) should be at least 2.4V when the output current (IOL) is -400μA.
- Output low voltage (VOL) should not exceed 0.4V when the output current (IOH) is 1.6mA.
- Input leakage current (IIH and IIL) should be within ±1μA.
Timing Parameters:
- The write cycle time (tWC) is 10ms.
- The read access time (tRC) is between 250ns and 550ns.
- The data hold time (tDH) is 50ns.
- The address setup time (tAS) is between 25ns and 100ns.
- The address hold time (tAH) is 50ns.
- The chip select pulse width (tCS) is 50ns.
Usage:
- Connect the VCC pin to the power supply and GND to ground.
- Use the chip select (CS), read/write (R/W), and enable (OE) pins to control data access.
- Ensure that the address lines (A0-A13) are correctly set to access the desired memory location.
- Data input/output (D0-D7) lines should be connected to the system bus for data transfer.
Programming:
- To write data, set the R/W line low and the CS line low, then provide the address and data.
- To read data, set the R/W line high and the CS line low, then provide the address and read the data from the D0-D7 lines.
Handling:
- Handle the device with care to avoid electrostatic discharge (ESD) damage.
- Store the device in a controlled environment within the specified temperature range.
Troubleshooting:
- If the device does not respond, check the power supply and connections.
- Verify that the timing parameters are met.
- Ensure that the address and data lines are correctly configured.
By following these instructions, you can effectively use the DS1286 in your application.
