| Notes | 1. CAx = column address, PAx = page address, BAx = block address ,the page address, block address called the row address. Byte address of page called column address |
| Page size x8 | 8640 bytes (2048 + 64 bytes) |
| Block size | 128 pages (1024K + 8K bytes) |
| Block number | 4096 blocks |
| LDMF4GA | Addressing |
| Instruction List | Function |
| Operating Steps | 1. An error occurred on page n of block A during erasing or programming operation.Copy the data from the first page to the (n-1) -th page of block A to the same position in the other empty block B.Copy the buffer data need to be saved to the n-th page position of block B.Add block A to the Bad block table. |
| Read operation | Read operation is implemented by writing 00h-30h command to the command register. First, write 00h command, then, write the address with 5 cycles, last, write 30h command. After completion, the R/B(-) is released. the user determine the completion of the internal data transmission by detecting the status of R/B(-). Once the completion of the transmission, the user can start the RE, the data read out continuously. |
| Programming operation | Before programming operation, user must erase the block firstly. Programming operation is implemented by writing 80h-10h command to the command register. First write 80h command, then, write the address with 5 cycles, and then load the data into the internal data buffer register, last, write 10h after the completion of the command to confirm Write. After programming completion, the R/B(-) is released. |
| Erase operation | The erase operation command is 60h-D0h. First write 60h command, then write the address with 3 cycles , and then write D0h command to confirm the erase. After the completion of erasing, R/B(-) is released. |
| Sequential instructions(-45ºC~175ºC) | As the temperature increases, the response speed of the device after operation can slow down.User program execution sequence a certain amount of allowance, suggest to increase the high temperature stability. |
| Timing parameter list(25ºC) | Symbol |
| PIN | Functional description |
|---|---|
| IO0 ~ IO7 | Multiplexed input / output The bidirectional I/Os transfer address, data, and command information. When C(-)E(-) pin is high,the I/Os is High impedance. |
| CLE | Command Latch Enable When CLE is high, the command is latched into the command register through the IO port on the rising edge of the signal. |
| ALE | Address Latch Enable When ALE is high,the address is latched into the address register through the IO port on the rising edge of the signal. |
| C(-)E(-) | Chip Enable Enables or disables the chip. |
| R(-)E(-) | Read Enable Control the output of serial data. When the signal is low, the data is driven to the IO port. Data is valid after tREA time on the falling edge of R(-)E(-), and the internal column address counter is incremented automatically. |
| W(-)E(-) | Write Enable Control the input of serial data,command, address and data is latched on the W(-)E(-) Rising edge. |
| R/B(-) | Ready/Busy output Indicates the device operating state. When low, indicates that programming, erase, or random read operation is in progress, when high, indicates that no operation or operation is finished. It is recommended to connect a pull-up resistor (4.7K~10K) to the pin. |
