Sequential Read In read modes (1), (2), and (3), when a command (00H, 01H, 50H) is input and an address specified, the address is automatically incremented and the read operation is continuously performed, by i nputting the RE clock. At this time, a Busy period (tR) occurs after the last address is accessed in a page. After the last address of the page is read out, the sequential read operation can be termi nated by bringing CE high. RB

Relationship between Command and Start Address (SA) during Sequential Read ‧ When the "00H" command is set, (SA) is set to area (A) and start from 0th address. ‧ When the "01H" command is set, (SA) is set to area (B) and start from 256th address. ‧ When the "50H" command is set, (SA) is set to area (C) and start from 512th address.

Status Read Status information can be output from the I/O pins with the RE clock following input of the 70H command. Status read is a function to recognize the status of the device from external. If the READ ST ATUS command is used to monitor the status of the device, user must re-issue the READ (00H) command before sequential page read cycle. Status Status output data Note I/O0 Ready / Busy 0 / 1 I/O1 Not used 0 I/O2 Not used 0 I/O3 Not used 0 I/O4 Not used 0 I/O5 Not used 0 I/O6 Ready / Busy 1 / 0 I/O7 Write protect 0

© Generalplus Technology Inc. Proprietary & Confidential 15 Dec. 21, 2009 Version: 1.4 4.17. ID Read To recognize the ID code (maker code / device code) of this device in a system, execut e the ID read command. The ID code can b e read with the following timing. Value Description st Byte C2H Maker Code nd Byte 79H Device Code th Byte reserved - th Byte reserved - th Byte reserved - th Byte reserved - th Byte reserved - th Byte reserved Title ID th Byte reserved Title ID Cautions: 1. If the RE clock is input after the maker code and device code are output, the output data is not guaranteed. Therefore, do not input the RE clock following device code output. 2. Do not input an address other than 00H after setting the ID read command (90H). If an address other than 00H is input, the data following RE clock input is not guaranteed.

READY/BUSY The device has a RB output that provides a hardware method of random read completion. The RB pin is normally high but transiti ons to low after random read is started after address loading. It re turns to high when the internal controller has finished the opera tion. The pin is an open-drain driver thereby allowing two or more RB outputs to be Or-tied. Because pull-up resistor value is related to tr (RB), an appropriate value can be obtained with the following reference table (Rp vs. tr, tf).

Rated operation Operation using timing other than shown in the timing charts is not guaranteed. 4.20.2. Commands that can be input The only commands that can be input are 00H, 01H, 50H, 70H, 90H, and FFH. Do not input any other commands. If other commands are input, the subsequent operation is not guaranteed. 4.20.3. Command limitations during Busy period Do not input commands other than the reset command and status read command during the Busy period. If a command is input durin g the Busy period, the subsequent operation is not guaranteed. 4.20.4. 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. 4.20.5. 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 follo wing power on. 4.20.6. Cautions during read mode „ Perform address input immediately following command input. If address input is done without performing command input first, t he 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.
