2) RAM
The RAM is a data memory for storing various kinds of data, and has a capacity of 2,048 words
×
4 bits. The
RAM area is assigned to addresses 0000H to 07FFH on the data memory map. Addresses 0100H to 01FFH
are 4-bit/16-bit data accessible areas and in other areas it is only possible to access 4-bit data.
When programming, refer to the "Technical Manual" of the E0C63358 or E0C63158.
Note: Pay attention to the application data size since the RAM of the E0C63358/E0C63158 is smaller (512

Oscillation Circuit
In the E0C63P366, only crystal oscillation is available for the OSC1 oscillation circuit and either ceramic or CR
oscillation is available for the OSC3 oscillation circuit. Furthermore, pay attention to the difference on the oscilla-
tion start time according to the supply voltage. Be sure to have enough margin especially for stabilizing the OSC3
oscillation when controlling the peripheral circuit that uses the OSC3 clock.
∗
The E0C63P366 has differences in its production process from the mask ROM models (E0C63358 and
E0C63158). The constant must be decided according to the characteristics of the mask ROM model.
