Note)
13 The value in x V can be found by the following expression:
I
SVDN (VDD = x V) = (x × 20) - 30 (Typ. value), ISVDN (VDD = x V) = (x × 30) - 30 (Max. value

■ STANDARD MASK OPTION PRODUCT E0C88316F02
● Specifications
E0C88316F02 is a general purpose MPU, or E0C88316 with the following options. Through external connection
of a program ROM, evaluation of E0C88316 and evaluation of LCD's display quality become possible.
Also, in case the E0C88316 appears to be in short of the ROM capacity for an intended application, combination
of this E0C88316F02 + External ROM may be good enough for the intended mass production application.
