1. ROM Size

❑ HD404864

❑ HD404868

4 kwords

8 kwords

2. Function Options

* ❑ 32 kHz CPU operation, realtime clock time base

* ❑ No 32 kHz CPU operation, realtime clock time base

❑ No 32 kHz CPU operation, no realtime clock time base

Note: When an asterisked item is selected, "crystal resonator" is necessary for subsystem oscillator (X1

X2).

3. ROM Code Data Organization

For a microcomputer with EPROM mounted (including a ZTAT™ microcomputer), specify the combined upper/lower

type.

❑ Combined lower/upper type

• Both the lower 5 data bits (L) and the upper 5 data bits (U) are written to a single EPROM in the order LULULU...

❑ Separate lower/upper type

• The lower 5 data bits (L) and upper 5 data bits (U) are written to separate EPROMs respectively.

4. System Oscillator (OSC1-OSC2)

❑ Ceramic oscillator

f=

MHz

❑ Crystal oscillator

f=

MHz

❑ External clock

f=

MHz

5. Subsystem Oscillator (X1 X2)

❑ Not used

—

❑ Crystal resonator f = 32.768 kHz

6. Stop Mode

❑ Yes (used)

❑ No (not used)

7. Package
