MEMORY MAP

The start address (SA) during read operation is specified divided into three areas using three types of read
commands.

- In read mode (1), start address (SA) is set in area (A).

- In read mode (2), start address (SA) is set in area (B).

- In read mode (3), start address (SA) is set in area (C).

One page consists of a total of 528 bytes broken down into 512 bytes (main memory) and 16 bytes (redundancy).
One block consists of 32 pages.

Caution The data of area (C) is redundancy, which is not programmable and is fixed to all FFH.

Sequential Read

In read modes (1), (2), and (3), when a command (00H, 01H, 50H) is input and an address specified, if it is in the
block that includes the address that was specified first, the address is automatically incremented and the read
operation is continuously performed until the last address in the same block, by inputting the RE# clock. At this time,
a Busy period (tR) occurs after the last address is accessed in a page.

Note :To perform read again after reading the 527th byte of data of the last page of block, stop the read operation once, and
then restart the read operation by inputting again the read command and an address.

Relationship Between Command and Start Address (SA) during Sequential Read

· When the "00H" command is set, the start address (SA) is set to area (A).

· When the "01H" command is set, the start address (SA) is set to area (B).

· When the "50H" command is set, the start address (SA) is set to area (C).

[Usage Cautions]

(1) Rated operation

Operation using timing other than shown in the timing charts is not guaranteed.

(2) Commands that can be input

The only commands that can be input are 00H, 01H, 50H, and FFH. Do not input any other commands.
If other commands are input, the subsequent operation is not guaranteed.

(3) Command limitations during Busy period

Do not input commands other than the reset command (FFH) during the Busy period. If a command is input
during the Busy period, the subsequent operation is not guaranteed.

(4) Cautions regarding RE clock

· Following the last RE clock, do not input the RE clock until the RB pin changes from Busy to Ready.

· Do not input the RE clock other than during data output.

(5) Cautions upon power application

Since the state of the device is undetermined upon power on, input high level to the CE pin and execute the reset
command following power on.

(6) Cautions during read mode

· Perform address input immediately following command input. If address input is done without performing com-
mand input first, the correct data cannot be output because the operation mode is undetermined.

· To execute the read mode after the read mode has been stopped with the reset command (FFH) and CE, input
again a command and address.

(7) Busy output following access of last address in page in read mode

After the access to the last address in a page, if the delay (tRHCH) from RE to CE is 30 ns or less, the Ready
status is maintained and Busy is not output by keeping CE high level for a set period (tCEH).
