Product Identifier
Product identifier read is a mode provided so that applications can confirm that the device was manufactured by SANYO
Electric Co., Ltd. This mode can be accessed by both hardware and software operations. A ROM writer is normally used
with this hardware operation to recognize the correct algorithm for the SANYO LE28F4001 Series. We recommend that
user use the software operation for recognizing this device. The “Functional Logic” section describes the hardware
operation in detail. The manufacturer and device code are accessed in the same manner.
Decoupling Capacitors
Ceramic capacitors (0.1 μF) must be added between V
CC
and V
SS
for each device to assure stabile flash memory
operation.
