1.0 Description

SmartMedia 128MByte Product Manual

The SanDisk SmartMedia Card is a 3.3-V 1-Gbit (1,107,296,256) NAND Electrically Erasable and Programmable Read-Only Memory (NAND E

2

PROM) device, organized as 528 bytes X 32 pages X 8192 blocks. This device has a 528-byte static register which allows program and read data to be transferred between the register and the memory cell array in 528-byte increments. The Erase operation is implemented in a single block unit (16 Kbytes + 512 bytes: 528 bytes X 32 pages).

The SanDisk SmartMedia Card is a serial-type memory device which uses the I/O pins for both address and data input and output as well as for command inputs. The Erase and Program operations are automatically executed making the device ideal for applications such as solid-state file storage, voice recording, image storage for digital cameras and other systems which require high-density non-volatile memory data storage.

PIN NAMES

Command Latch Enable: CLE

The CLE input signal is used to control loading of the operation mode command into the internal command register. The command is latched into the command register from the I/O port on the rising edge of the

WE signal while CLE is High.

Address Latch Enable: ALE

The ALE signal is used to control loading of either address information or input data into the internal address/data register. Address information is latched on the rising edge of

WE if ALE is High. If ALE is

Low, input data is latched.

Chip Enable:

The device goes into a low-power Standby Mode when signal is ignored when the device is in the Busy state ( operation, and will not enter Standby Mode even if the

CE

CE goes High during a Read operation. The CE

R/B= L), such as during a Program or Erase

CE input goes High. The CE signal must stay Low

during the Read Mode Busy state to ensure that memory array data is correctly transferred to the data register.

Write Enable:

The

WE signal is used to control the acquisition of data from the I/O port.

26

WE

SmartMedia 128MByte Product Manual

Read Enable:

The

RE signal controls serial data output. Data output will be valid when

RE

RE goes low after t

. The

internal column address counter is also incremented (Address = Address + l) on this falling edge.

I/O Port: I/OI to 8

The I/O1 to 8 pins are used as ports for transferring address, command and input/output data to and from the device.

Write Protect:

The

WP signal is used to protect the device from accidental programming or erasing. The internal voltage

regulator is reset when

WP

WP is Low. This signal is usually used for protecting the data during the

power-on/off sequence when input signals are invalid. The signal assertion during the program or erase operation causes the operation to cancel, not interrupt, even if the card is busy.

Ready/Busy: R/B

The R/B output signal is used to indicate the operating condition of the device. The R/B signal is in Busy

R/B = L) during the Program, Erase and Read operations and will return to Ready state (R/B = H)

state ( after completion of the operation. The output buffer for this signal is an open drain.

Low Voltage Detect: LVD (SmartMedia Card only)

The LVD signal is used to detect the power supply voltage level.

4.0 Device Operation

4.1 Read Mode (1)

Read mode (1) is set when an 00H command is issued to the Command register. Refer to Figure 4-1 below for timing details and the block diagram.

Figure 4-1 Read Mode (1) Operation

30

4.2 Read Mode (2)

SmartMedia 128MByte Product Manual

Figure 4-2 Read Mode (2) Operation

31

SmartMedia 128MByte Product Manual

4.3 Read Mode (3)

Read mode (3) has the same timing as Read modes (1) and (2) but is used to access information in the extra 16-byte redundancy area of the page. The start pointer is therefore set to a value between byte 512 and byte

527.

Figure 4-3 Read Mode (3) Operation

4.4 Sequential Read (1) (2) (3)

This mode allows the sequential reading of pages without additional address input.

Figure 4-4 Sequential Read (1) (2) (3) Operation

32

SmartMedia 128MByte Product Manual

Sequential Read modes (1) and (2) output the contents of addresses 0 to 527 as shown above, while Sequential Read mode (3) outputs the contents of the redundant address locations only. When the page address reaches the next block address, read command (00H/01H/50H) and address input are needed.

4.5 Status Read

The SmartMedia Card has two Status Read commands. One is Status Read (1) command 70H and the other is Status Read (2) command 71H.

This device automatically implements the execution and verification of the Program and Erase operations. The Status Read function is used to monitor the Ready/Busy status of the device, determine the result (pass /fail) of a Program or Erase operation, and determine whether the device is in Protect mode. The device status is output via the I/O port on the

RE clock after a 70H or 71H command input.

The resulting information of the Status Read (1) command 70H is outlined in the table below and the resulting information of Status Read (2) command 71H is outlined in the explanation for Multi Block Program and Multi Block Erase toward the end of this document.

4.7 Auto Block Erase

SmartMedia 128MByte Product Manual

The Auto Block Erase operation starts on the rising edge of

WE after the Erase Start command DOH

which follows the Erase Setup command 60H. This two-cycle process for Erase operations acts as an extra layer of protection from accidental erasure of data due to external noise. The device automatically executes the Erase and Verify operations.

Figure 4-8 Auto Block Erase Operation

35

SmartMedia 128MByte Product Manual

4.8 Multi Block Program

The device carries out a Multi Block Program operation when it receives a 15H or 10H Program command after some sets of the address and data have been input.

In the interval of the Multi District address and the data input (512+16Byte), 11H Dummy Program command is used when it still continues the data input into another District. The sequence of command, address and data input is shown below.

Figure 4-9 Multi Block Program Operation

After 15H Cache Program command, physical programming starts as follows.

Starting the upper operation from the first page of the selected erase blocks, and then repeating the operation for a total of 31 times while incrementing the page address in the blocks, and then inputting the last page data of the blocks, the 10H command executes final programming.

36

SmartMedia 128MByte Product Manual

In this full sequence, the command sequence is below.

4.8.1 Internal Addressing in Relation with the Districts

I/O1 describes total Pass/ Fail condition. If at least one fail occurred in 32 times X 4 (512+16Byte) page write operation, it shows “Fail” condition,

I/O2 describes total Pass/ Fail condition. If at least one fail occurred in 32 times X 1 (512+16Byte) page write operation in District 0 area, it shows “Fail” condition,

I/O3, I/O4 and I/O5 are as same manner as I/O2.

To use the Multi Block Program operation, the internal addressing should be such that at most one block is selected within each district.

37

SmartMedia 128MByte Product Manual

The device consists of two chips, each of which has four Districts. Each District consists from 1024 erase blocks. The allocation rule is follows.

Chip0, District0 : Block0, Block4, Block8, Block12, …..,Block4092 Chip0, District1 : Block1, Block5, Block9, Block13, …..,Block4093 Chip0, District2 : Block2, Block6, Block10, Block14, …..,Block4094 Chip0, District3 : Block3, Block7, Block11, Block15, …..,Block4095

4.8.2 Address Input Restriction for the Multi Block Program Operation

In selecting the blocks for the Multi Block Program operation, the conditions below apply.

• Restriction

- Maximum one block should be selected from each District.

- The data input operation should be started from the same number page of the selected block and the page number in the blocks should be the same number at programming time.

• Acceptance

- There is no order limitation of the District for address input.

- Any number of the District can be select for programming.

- For example, the following operation is acceptable.

- (80) [District2] (11) (80) [District0] (11) (80) [District1] (15)

No mutual address relation between the selected blocks from each District is required.

4.8.3 Operating Restriction During the Multi Block Program Operation

• Restriction—Starting from the first page of data input, until the device issues a 10H command, any other command out of defined sequence can not be issued except Status Read and Reset commands.

• Acceptance—The data input operation can be terminated with the 10H command instead of 15H command in the middle of the page number in the block. In this case the Status represents the reflected value accumulated from first page programming of this sequence and up to the last page programming terminated by 10H command.

4.9 Status Read Operation

Until the Ready condition after the programming is terminated by a 10H command, the effective bit in the Status data is limited to the Ready/Busy bit. In other words, Pass/Fail condition can be checked only in the Ready condition after a 10H command.

38

SmartMedia 128MByte Product Manual

4.10 Multi District Block Erase

The device carries out a Multi District Block Erase operation when it receives a D0H command after some sets of the address have been input. After the D0H command, the total results of the Erase operation are shown through the Status Read (2) command 71H.

Figure 4-12 Status Read (2) Command

I/O3, I/O4 and I/O5 are the same as I/O2.

4.10.1 Internal Addressing in Relation with the Districts

To use the Multi Block Erase operation, the internal addressing should be such that at most one block is selected within each district.

The device consists of two chips, each of which has four Districts.

Each District consists of 1024 erase blocks.

39

SmartMedia 128MByte Product Manual

4.10.2 Address Input Restriction for the Multi District Block Erase Operation

In selecting the blocks for the Multi District Block Erase operation, the conditions below apply.

• Restriction—Maximum one block should be selected from each District.

• Acceptance—There is no order limitation of the District for the address input. Any number of the Districts can be select for the erase operation. For example, the following operation is in acceptance: (60) [District2] (60) [District0] (60) [District1] (D0).

No mutual address relation between the selected blocks from each District is required.

4.11 Reset

The Reset mode stops all operations. For example, in the case of a Program or Erase operation the internally generated voltage is discharged to 0 volts and the device enters the Wait state. The address and data registers are set as follows after a Reset:

• Address Register: All “0”

• Data Register: All “1”

• Operation Mode: Wait state

The response to an FFH Reset command input during the various device operations is as follows:

5.0 Application Notes and Comments

5.1 Prohibition of Unspecified Commands

The operation commands are listed in Table 3-3. Input of a command other than those specified in Table 3-3 is prohibited. Stored data may be corrupted if an unknown command is entered during the command cycle.

5.2 Restriction of Commands While in Busy State

During the Busy state, do not input any command except 70H, 71H or FFH.

5.3 Pointer Control for 00H, 01H and 50H

The device has three Read modes which set the destination of the pointer. Table 5-1 shows the destination of the pointer, and Figure 5-1 is a block diagram of their operations.

Table 5-1 Pointer Destination

Read Mode Command Pointer

(1) 00H 0 to 255

(2) 01H 256 to 511

(3) 50H 512 to 527

The pointer is set to region A by the 00H command, to region B by the 01H command, and to region C by the 50H command. For example, the 00H command must be input to set the pointer back to region A when the pointer is pointing to region C. To program region C only, set the start point to region C using the 50H command.

SmartMedia 128MByte Product Manual

5.5 Status Read During a Read Operation

The device status can be read out by inputting the Status Read command 70H in Read mode. Once the device has been set to Status Read mode by a 70H command, the device will not return to Read mode. Therefore, a Status Read during a Read operation is prohibited. However, when the Read command 00H is input during [A], Status mode is reset and the device returns to Read mode. In this case, data output starts automatically from address N and address input is unnecessary.
