3.3Pin I/O Circuits and Recommended Connection of Unused Pins

The I/O circuit type for each pin and recommended connections of unused pins are shown in Table 3-1.

For the I/O circuit configuration of each type, refer to Figure 3-1.

Table 3-1. Types of Pin I/O Circuits and Recommended Connection of Unused Pins

4.MEMORY SPACE

The μPD789860 and μPD789861 can each access a 64 KB memory space. Figure 4-1 shows the memory map.

Data Sheet U13917EJ1V1DS13

5. EEPROM

Besides internal high-speed RAM, the μPD789860 and μPD789861 have 32 × 8 bits of electrically erasable PROM (EEPROM) on-chip as data memory.

Unlike normal RAM, EEPROM can maintain its contents even if its power supply is cut. In addition, unlike EPROM, its electrical contents can be erased without using ultraviolet rays.

6.2Clock Generator

The clock generator specifications differ as follows for the μPD789860 and μPD789861.

?Ceramic/crystal oscillation: μPD789860

Oscillates at frequency from 1.0 to 5.0 MHz. Minimum instruction execution time can be switched between 0.4μs and 1.6 μs (@ 5.0 MHz operation).

?RC oscillation: μPD789861

Oscillates at frequency of 1.0 MHz ±15%. Minimum instruction execution time can be switched between 2.0 μs and 8.0 μs (@ 1.0 MHz operation).
