Memory DensiTIes From 8k x 8 Through 512k x 8 in the Same FootprintThe PowerCap package provides for an easy memory density upgrade without having to change the PCB hardware layout. When designing this package into a system, the higher order address signals should be connected to the package so that a higher density NV RAM can be added to the system without hardware modifications. All three family types have power, ground, address, data, and control signals on the same pins. Depending on the family type, pins 1, 4, 33, and 34 have other functions associated with them.

The two-piece assembly protects the lithium battery, contained in the PowerCap (upper half) from the high temperatures of reflow soldering. The module base (lower half) is a small PCB with surface-mount leads, SRAM, and controller ICs. After the module base is surface-mounted, the PowerCap is snapped onto the base to complete the module.
The PowerCap is ordered separately from the base. The DS9034 PowerCap contains a battery for bytewide module bases. The DS9034PCX contains a battery and crystal to operate the real-time clock in the clock bases.
| PowerCap | Module Base |
| DS9034PC | Bytewide NV SRAM |
| DS9034PCX | Bytewide Clock |
| DS9034PCX | Phantom Clock |
| DS9034PCX | Watchdog Clock |
Touchless Sensor-Makes it germ Free
Environment Friendly-Prevents Contamination
Ideal fit for Kitchen/Bathroom/Bedroom
As users hands or debris enter the zone 6 inches (15cm) from the infrared sensor on top of the dustbin, the lid will automatically open.
The Lid will remain open if hand or debris is within the 6 inch (15cm) range of the infrared sensor. Lid will close 7 seconds after users hands move away.
The new touch switch panel has higher stability and efficiency. you can use it effortlessly. There are [OPEN" & [CLOSE" buttons for manual operation, and there is a ON/OFF power switch on the back of the dustbin.
The new removable plastic rim is easy to lift out, and the plastic ring helps leave no excess plastic bag visible (w/o liner).
