CDP6402CE datasheet by Harris Semiconductor

CDP6402CE Frequently Asked Questions (FAQs)

• What is the maximum clock frequency that the CDP6402CE can operate at?
  The CDP6402CE can operate at a maximum clock frequency of 2 MHz.
• How do I interface the CDP6402CE with a microprocessor?
  The CDP6402CE can be interfaced with a microprocessor using the chip select (CS) and read/write (R/W) signals. The CS signal is used to select the CDP6402CE, and the R/W signal is used to control the direction of data transfer.
• What is the purpose of the VPP pin on the CDP6402CE?
  The VPP (Programming Power) pin is used to supply the programming voltage required for programming the device. It should be connected to a voltage source of 12.5V ± 0.5V during programming.
• How do I program the CDP6402CE?
  The CDP6402CE can be programmed using a programming voltage of 12.5V ± 0.5V applied to the VPP pin. The device can be programmed using a programming algorithm that involves applying specific voltage levels to the address and data pins.
• What is the data retention period of the CDP6402CE?
  The CDP6402CE has a minimum data retention period of 10 years at a temperature of 25°C.
