8-bit CMOS Flash Memory
The Hitachi HN28F101 is a 131072-word x 8-bit
CMOS flash Memory, realizing on-board
programming. It programs or erases data with only
on-board power supply (12 V V
PP
supply/5 V
V
CC
supply). It programs data with fast program-
ming algorithm by command inputs. It has two
types of erase algorithm : automatic erase and fast
erase by command inputs. Automatic erase func-
tion can erase data automatically without external
control only by inputting trigger pulse and inform
erase completion to CPU by status polling. The
HN28F101 can control programming erase
algorithm externally.

. Device identifier code can be output by
command inputs.
4. Refer to the table of command address and data input. Data is programmed, erased, or verified
after mode setting by command inputs.
5. Status of automatic erase can be verified in this mode. Status outputs on I/O7. I/O0 to I/O6 are
in high impedance state.
