Frequently Asked Questions

What is the essential property of the 93LC66C?
The 93LC66C devices are 4Kbit low-voltage serial Electrically Erasable PROMs (EEPROM). Word-selectable devices 93LC66C are dependent upon external logic levels driving the ORG pin to set word size.
In the Erase/Write Disable (EWDS) state, how to power up the device?
The 93LC66C powers up in the Erase/Write Disable (EWDS) state. All Programming modes must be preceded by an Erase/Write Enable (EWEN) instruction. Once the EWEN instruction is executed, programming remains enabled until an EWDS instruction is executed or Vcc is removed from the device.
