Preliminary W77LE58
Publication Release Date: August 1999
- 69 - Revision A1
Program/Erase Inhibit Operation
This operation allows parallel erasing or programming of multiple chips with different data. When
P3.6(CE) = V
IH
, P3.7(OE) = V
IH
, erasing or programming of non-targeted chips is inhibited. So,
except for the P3.6 and P3.7 pins, the individual chips may have common inputs.
Company/Device ID Read Operation
This operation is supported for MTP ROM programmer to get the company ID or device ID on the
W77LE58.
