The following are the functional descriptions and timing diagrams of all seven instructions. No data can be written into the device in the programming disabled state. Functional operation of this device at other conditions beyond those listed in the specification is not implied and prolonged exposure to extreme conditions datxsheet affect device reliability.
The device is optimized for use in many industrial and commercial applications where low power and low voltage operation are essential. Since the internal auto-timing generator provides all datashee signals for the internal erase, so the SK clock is not required.
The 8 bits or 16 bits data stream is preceded by a logical? For the most up-to-date information, please visit our web site at http: After the erase-all instruction set has been issued, the data erase feature is activated by the falling edge of CS.
By popular microcontroller, the versatile serial interface including chip select CSserial clock SKdata input DI and data output DO can be easily controlled. After power on, the device is by default in the EWDS state. Since the internal auto-timing generator provides all timing signal for the internal writing, so the SK clock is not required. The applications mentioned herein are used solely for the purpose of illustration and Holtek makes no warranty or representation that such applications will be suitable without further modification, nor recommends the use of its products for application that may present a risk to human life due to malfunction or otherwise.
After the data word has been read the internal address will be automatically incremented by 1 allowing the next consecutive data word to be read out without entering further address data.

These serial instruction data presented at the DI input will be written into the device at the rising edge of SK. Stresses exceeding the range specified under? Its bits of memory are organized into 64 words of 16 bits each when the ORG pin is connected to VCC or organized into words of 8 bits each when it is tied dstasheet VSS. The auto-timing write cycle includes an automatic erase-before-write capability. For successful instructions, CS must be low once after the instruction is sent.
Since the internal auto-timing generator provides all timing signals for the write-all operation, so the SK clock is not required. Test Conditions Input rise and fall time: Taipei Sales Office 4F-2, No. There is an internal pull-up resistor on the ORG pin.

The data on DO pin changes during the low-to-high edge of SK signal. At both the power on and power off state the device automatically entered the disable mode. Since the internal auto-timing generator provides all timing signal for the erase-all operation, so the SK clock is not required. The DO pin will remain low but when the operation is over the DO pin will return to high and further instruction can be executed.
The DO pin will remain low but when the operation is over, the DO pin will return to high and further instructions can be executed. When the user selectable internal organization is arranged into 64? After the write-all instruction set has been issued, the data writing is activated by the falling edge of CS.

Holtek reserves the right to alter its products without prior notification. By so doing, the internal memory data can be protected. However, Holtek assumes no responsibility arising from the use of the specifications described. The DO pin will remain low but when the operation is over, the DO pin will return to high and further instruction can be executed.
These are stress ratings only.
