Some failed sectors may exist in the device. The failed sectors can be recognized by reading the sector valid data written in a part of the column address 800 to 83F (The specific address is TBD.). The sector valid data must be read and kept outside of the sector before the sector erase. When the sector is programmed, the sector valid data should be written back to the sector. 2. An × means "Don't care". The pin level can be set to either VIL or VIH, referred to DC characteristics. 5 HN29W25611S Series Pin Function CE: CE is used to select the device. The status returns to the standby at the rising edge of CE in the reading operation. However, the status does not return to the standby at the rising edge of CE in the busy state in programming and erase operation. OE: Memory data and status register data can be read, when OE is VIL . WE: Commands and address are latched at the rising edge of WE. SC: Programming and reading data is latched at the rising edge of SC. RES: RES pin must be kept at the VILR (V SS ± 0.2 V) level when VCC is turned on and off. In this way, data in the memory is protected against unintentional erase and programming. RES must be kept at the VIHR (VCC ± 0.2 V) level during any operations such as programming, erase and read. CDE: Commands and data are latched when CDE is VIL and address is latched when CDE is VIH. RDY/Busy: The RDY/Busy indicates the program/erase status of the flash memory. The RDY/Busy signal is initially at a high impedance state. It turns to a VO L level after the (40H) command in programming operation or the (B0H) command in erase operation. After the erase or programming operation finishes, the RDY/Busy signal turns back to the high impedance state. I/O0 to I/O7: The I/O pins are used to input data, address and command, and are used to output memory data and status register data.

Default mode after the power on is the status register read mode (refer to status transition). From I/O0 to I/O7 pins output the status, when CE = VIL and OE = VIL (conventional read operation condition). 2. Refer to the command definition. Data can be read, programmed and erased after commands are written in this mode. 3. The RDY/Busy bus should be pulled up to VCC to maintain the VOH level while the RDY/Busy pin outputs a high impedance. 4. An × means “Don’t care”. The pin level can be set to either VIL or VIH referred to DC characteristics. 6 HN29W25611S Series Command Definition*1, 2 First bus cycle Second bus cycle Operation Data in mode*3 Operation Data in mode Write 00H Write SA (1)*4 3 + 2h*6 Write 00H Write SA (1)*4 Serial read (2) 3 Write F0H Write SA (1)*4 Read identifier codes 1 Write 90H Read ID*8, 9 Data recovery read 1 Write 01H Read Recovery data Single sector 4 Write 20H Write SA (1)*4 (Without CA*7) 4 Write 10H Write SA (1)*4 (With CA*7) 4 + 2h*6 Write 10H Write SA (1)*4 4 Write 1FH Write SA (1)*4 Program (3) (Control bytes)*7 4 Write 0FH Write SA (1)*4 (WithoutCA*7) 4 Write 11H Write SA (1)*4 4 + 2h*6 Write 11H Write SA (1)*4 Reset 1 Write FFH Clear status register 1 Write 50H Bus cycles Command Read Serial read (1) (Without CA) 3 (With CA) Auto erase Auto program Program (1) Program (2)*10 Program (4) (With CA*7) Data out 7 HN29W25611S Series Third bus cycle Fourth bus cycle Operation mode Data in Operation mode Data in Write SA (2)*4 3 + 2h*6 Write SA (2)*4 Write CA (1)*5 Serial read (2) 3 Write SA (2)*4 Read identifier codes 1 Data recovery read 1 Single sector 4 Write SA (2)*4 Write B0H*11 (Without CA*7) 4 Write SA (2)*4 Write 40H *11, 12 (With CA*7) 4 + 2h*6 Write SA (2)*4 Write CA (1) 4 Bus cycles Command Read Serial read (1) (Without CA) 3 (With CA) Auto erase Auto program Program (1) 10 4 Write SA (2)* Write 40H *11, 12 Program (3) (Control bytes)*7 4 Write SA (2)*4 Write 40H *11, 12 (WithoutCA*7) 4 Write SA (2)*4 Write 40H *11, 12 4 + 2h*6 Write SA (2)*4 Write CA (1) Program (2)* Program (4) (With CA*7) Reset 1 Clear status register 1 8 HN29W25611S Series Bus cycles Command Read Sixth bus cycle Operation mode Operation mode Data in CA (2)*5 Write 40H *11, 12 CA (2) Write 40H *11, 12 Data in Serial read (1) (Without CA) 3 3 + 2h*6 Write (With CA) Auto erase Fifth bus cycle Serial read (2) 3 Read identifier codes 1 Data recovery read 1 Single sector 4 Auto program Program (1) (Without CA*7) 4 (With CA*7) 4 + 2h*6 Write Program (2)*10 CA (2)*5 4 7 Program (3) (Control bytes)* 4 Program (4) (WithoutCA*7) 4 (With CA*7) 4 + 2h*6 Write Reset 1 Clear status register 1 Notes: 1. Commands and sector address are latched at rising edge of WE pulses. Program data is latched at rising edge of SC pulses. 2. The chip is in the read status register mode when RES is set to VIHR first time after the power up. 3. Refer to the command read and write mode in mode selection. 4. SA (1) = Sector address (A0 to A7), SA (2) = Sector address (A8 to A13). 5. CA (1) = Column address (A0 to A7), CA (2) = Column address (A8 to A11). (0 A11 to A0 83FH) 6. The variable h is the input number of times of set of CA (1) and CA (2) (1 h 2048 + 64). Set of CA (1) and CA (2) can be input without limitation. 7. By using program (1) and (3), data can additionally be programmed for each sector before erase. 8. ID = Identifier code; Manufacturer code (07H), Device code (99H). 9. The manufacturer identifier code is output when CDE is low and the device identifier code is output when CDE is high. 10. Before program (2) operations, data in the programmed sector must be erased. 11. No commands can be written during auto program and erase (when the RDY/Busy pin outputs a VOL ). 12. The fourth or sixth cycle of the auto program comes after the program data input is complete. 9 HN29W25611S Series Mode Description Read Serial Read (1): Memory data D0 to D2111 in the sector of address SA is sequentially read. Output data is not valid after the number of the SC pulse exceeds 2112. When CA is input, memory data D (m) to D (m + j) in the sector of address SA is sequentially read. Then output data is not valid after the number of the SC pulse exceeds (2112 to m). The mode turns back to the standby mode at any time when CE is VIH. Serial Read (2): Memory data D2048 to D2111 in the sector of address SA is sequentially read. Output data is not valid after the number of the SC pulse exceeds 64. The mode turns back to the standby mode at any time when CE is VIH. Automatic Erase Single Sector Erase: Memory data D0 to D2111 in the sector of address SA is erased automatically by internal control circuits. After the sector erase starts, the erasure completion can be checked through the RDY/Busy signal and status data polling. All the bits in the sector are "1" after the erase. The sector valid data stored in a part of memory data D2048 to D2111 must be read and kept outside of the sector before the sector erase. Automatic Program Program (1): Program data PD0 to PD2111 is programmed into the sector of address SA automatically by internal control circuits. When CA is input, program data PD (m) to PD (m + j) is programmed from CA into the sector of address SA automatically by internal control circuits. By using program (1), data can additionally be programed for each sector before the following erase. When the column is programmed, the data of the column must be [FF]. After the programming starts, the program completion can be checked through the RDY/Busy signal and status data polling. Programmed bits in the sector turn from "1" to "0" when they are programmed. The sector valid data should be included in the program data PD2048 to PD2111. Program (2): Program data PD0 to PD2111 is programmed into the sector of address SA automatically by internal control circuits. After the programming starts, the program completion can be checked through the RDY/Busy signal and status data polling. Programmed bits in the sector turn from "1" to "0" when they are programmed. The sector must be erased before programming. The sector valid data should be included in the program data PD2048 to PD2111. Program (3): Program data PD2048 to PD2111 is programmed into the sector of address SA automatically by internal control circuits. By using program (3), data can additionally be programed for each sector befor the following erase. When the column is programmed, the data of the column must be [FF]. After the programming starts, the program completion can be checked through the RDY/Busy signal and status data polling. Programmed bits in the sector turn from "1" to "0" when they are programmed. 10 HN29W25611S Series Program (4): Program data PD0 to PD2111 is programmed into the sector of address SA automatically by internal control circuits. When CA is input, program data PD (m) to PD (m + j) is programmed from CA into the sector of address SA automatically by internal control circuits. By using program (4), data can be rewritten for each sector before the following erase. So the column data before programming operation are either "1" or "0". In this mode, E/W number of times must be counted whenever program (4) execute. After the programming starts, the program completion can be checked through the RDY/Busy signal and status data polling. The sector valid data should be included in the program data PD2048 to PD2111. 16383 16383 Sector address 16383 Sector address Sector address Memory array Memory array 0 Memory array 0 0 2111 Register Serial read (1) (Without CA) Program (1) (Without CA) Program (2) 0 0 Column address 2111 Register Serial read (1) (With CA) Program (1) (With CA) 0 2048 2111 Register Serial read (2) Program (3) Status Register Read The status returns to the status register read mode from standby mode, when CE and OE is VIL. In the status register read mode, I/O pins output the same operation status as in the status data polling defined in the function description. Identifier Read The manufacturer and device identifier code can be read in the identifier read mode. The manufacturer and device identifier code is selected with CDE VIL and V IH, respectively. Data Recovery Read When the programming was an error, the program data can be read by using data recovery read. When an additional programming was an error, the data compounded of the program data and the origin data in the sector address SA can be read. Output data are not valid after the number of SA pulse exeeds 2112. The mode turns back to the standby mode at any time when CE is VIH. The read data are invalid when addresses are latched at a rising edge of WE pulse after the data recovery read command is written. 11 HN29W25611S Series Command/Address/Data Input Sequence Serial Read (1) (With CA before SC) Command /Address 00H SA (1) SA (2) CA (1) CA (2) CA (1)' CA (2)' CDE WE SC Low Data output Data output Serial Read (1) (With CA after SC) Command /Address 00H SA (1) SA (2) CA (1) CA (2) CA (1)' CA (2)' CDE WE SC Low Data output Data output Data output Serial Read (1) (Without CA), (2) Command/Address 00H/F0H SA (1) SA (2) CDE WE SC Low Data output Single Sector Erase Command/Address 20H SA (1) SA (2) B0H CDE WE SC Low Erase start 12 HN29W25611S Series Program (1), (4) (With CA before SC) Command /Address 10H/11H SA (1) SA (2) CA (1) CA (2) CA (1)' CA (2)' 40H CDE WE SC Low Data input Data input Program start Program (1), (4) (With CA after SC) Command /Address 10H/11H SA (1) SA (2) CA (1) CA (2) CA (1)' CA (2)' 40H CDE WE SC Low Data input Data input Data input Program start Program (1), (4) (Without CA) Command/Address 10H/11H SA (1) SA (2) 40H CDE WE SC Low Data input Program start Program (2) Command/Address 1FH SA (1) SA (2) 40H CDE WE SC Low Data input Program start 13 HN29W25611S Series Program (3) Command/Address 0FH SA (1) SA (2) 40H CDE WE SC Low Data input ID Read Mode Command/Address 90H CDE WE SC Low Manufacture Device code Manufacture code output output code output Data Recovery Read Mode Command/Address 01H CDE WE SC Low Data output 14 Program start HN29W25611S Series Status Transition VCC Deep standby Column address input Power off CA(1) CA(2) RES 00H/F0H FFH CE 90H Read (1) / (2) SA (1), SA (2) setup ID read setup CDE, OE Sector address OE, SC input CA(1)' OE CA(2)' SC Read (1) / (2) ID read FFH CE BUSY 20H FFH Sector Erase setup SA (1), SA (2) Sector address input B0H Erase start OE Status register read Erase finish Column address SC, CDE PD(m) input CA(1) CA(2) CE Standby CA(1)' to CA(2)' PD(m+j) PD0 to 10H SA (1), PD2111 OE 40H Output /11H SA (2) Program Sector address Program Program disable (1)/(4) setup input data input start FFH SC, CDE Program finish Status register read PD0 to 1FH SA (1), PD2111*3 OE 40H /0FH Program (2)/(3) SA (2) Sector address Status register Program Program read input data input setup start SC, CDE FFH Program finish Program error or Status register clear 50H Erase error CE*2 FFH*2 ERROR 01H*1 OE Notes: 1. 2. 3. 4.

The level of I/O7 pin turns to a VOH when the operation finishes. I/O5 and I/O4 pins output V OLs to indicate that the erase and program operations complete in a finite time, respectively. If these pins output VOHs, it indicates that these operations have timed out. When these pins monitor, I/O7 pin must turn to a VOH . To execute other erase and program operation, the status data must be cleared after a time out occurs. From I/O0 to I/O3 pins are reserved for future use. The pins output VOLs and should be masked out during the status data read mode. The function of the status register is summarized in the following table. I/O Flag definition Definition I/O7 Ready/Busy VOH = Ready, VOL = Busy I/O6 Reserved Outputs a V OL and should be masked out during the status data poling mode. I/O5 Erase check VOH = Fail, VOL = Pass I/O4 Program check VOH = Fail, VOL = Pass I/O3 Reserved Outputs a V OL and should be masked out during the status data poling mode.

The Unusable Sector Indication Flow 36 Column address = 820H to 825H HN29W25611S Series Requirements for High System Reliability The device may fail during a program, erase or read operation due to write or erase cycles. The following architecture will enable high system reliability if a failure occurs. 1. For an error in read operation: An error correction more than 3-bit error correction per each sector read is required for data reliability. 2. For errors in program or erase operations: The device may fail during a program or erase operation due to write or erase cycles. The status register indicates if the erase and program operation complete in a finite time. When an error occurred in the sector, try to reprogram the data into another sector. Avoid further system access to the sector that error happens. Typically, recommended number of a spare sectors are 1.8% of initial usable 16,057 sectors by each device. If the number of failed sectors exceeds the number of the spare sectors, usable data area in the device decreases. For the reprogramming, do not use the data from the failed sectors, because the data from the failed sectors are not fixed. So the reprogram data must be the data reloaded from external buffer, or use the Data recovery read mode (see the “Mode Description” and under figure “Spare Sector Replacement Flow after Program Error”). To avoid consecutive sector failures, choose addresses of spare sectors as far as possible from the failed sectors. 37 HN29W25611S Series START Program start Set an usable sector Program end Check RDY/Busy Check status Yes No Clear status register Load data from external buffer Data recovery read Program start Set another usable sector Program end Check RDY/Busy Check status Yes Check status: Status register read END Spare Sector Replacement Flow after Program Error 38 No HN29W25611S Series Memory Structure 16,384 sectors bit sector byte (8 bits) 2,112 bytes (16,896 bits) Bit: Minimum unit of data.
