93LC66BT-I serial EEPROM for Microwire designs

The YINGHUA 93LC66BT-I is a Microwire compatible serial EEPROM supplied in a SOT23-6 package. It provides non-volatile memory storage for small embedded designs that use the Microwire protocol. Engineers working on legacy or space-constrained boards can integrate this device directly. It is not suited for applications that require higher density storage or a different serial interface.

SOT23-6 footprint eases PCB placement

The six-lead SOT23-6 outline fits standard land patterns so hand soldering or automated assembly are both straightforward. Verify the supply voltage range in the datasheet before powering the circuit because incorrect voltage is the most common cause of failure. Ensure the Microwire timing parameters match your controller to avoid communication errors. The device is new and ready for production use.

Questions about this item

How can I confirm the 93LC66BT-I is communicating correctly after soldering the SOT23-6 package?

Verify the Microwire protocol signals on pins 1 through 6 with an oscilloscope or logic analyser, then read back a known test pattern to confirm the 5-8K memory array responds as expected.

What comes in the package and what extra items are needed to use the 93LC66BT-I?

The reel contains the 93LC66BT-I ICs in SOT23-6 footprint; you must supply a PCB with matching land pattern, solder paste, reflow equipment and a Microwire-compatible host controller.
