The MX25L6402 features a serial peripheral interface and software protocol allowing operation on a simple 3- wire bus. The three bus signals are a clock input (SCLK), a serial data input (SI), and a serial data output (SO). SPI access to the device is enabled by CS input. The MX25L6402 provide sequential read operation on whole chip. User may start to read from any byte of the array. While the end of the array is reached, the device will wrap around to the beginning of the array and continuously outputs data until CS goes high. After program/erase command is issued, auto program/ erase algorithms which program/erase and verify the specified page locations will be executed. Program command is executed on a page (128 bytes) basis, and erase command is executed on both chip and sector (64K bytes) basis. To provide user with ease of interface, a status register is included to indicate the status of the chip. The status read command can be issued to detect completion and error flag status of a program or erase operation. When the device is not in operation and CS is high, it is put in standby mode and draws less than 5uA DC current. The MX25L6402 utilizes MXIC's proprietary memory cell which reliably stores memory contents even after 100 program and erase cycles.

In standby mode, SO pin of this LSI should be High-Z. 3.When correct command is inputted to this LSI, this LSI becomes active mode and keeps the active mode until next CS rising edge. COMMAND DESCRIPTION (1) Read Array This command is sent with the 4-byte address (command included), and the byte address, followed by four dummy bytes sent to give the device time to stabilize. The device will then send out data starting at the byte address until CS goes high. The clock to clock out the data is supplied by the master SPI. The read operation is executed on whole array. If the end of the array is reached then the device will wrap around to the beginning of the array. (2) Read Status Register When this command is sent, the device will continuously send out the status register contents starting at bit7. The clock to clock out the data is supplied by the master SPI. bit7 program/erase bit6 NA bit5 NA completion Note1 bit4 erase error 1=error bit3 program error 1=error bit2 NA bit1 NA bit0 ready/busy 1=ready 0=busy Bit 6,5,2,1 = Reserve for future use. Bit 4 = "1" -----> There is an error occurred in last erase operation. = "0" -----> There is no error occurred in last erase operation. Bit 3 = "1" -----> There is an error occurred in last program operation. = "0" -----> There is no error occurred in last program operation. Bit 0 ="1" -----> Device is in ready mode. ="0" -----> Device is in busy mode. Note 1: The initial value of Bit7 is "1". Bit7 will have "1" to "0" transit only after program/erase operation is completed. Bit7 will shift from "0" to "1" only after issued program/erase/Clear status register command. Please note the Bit7=0 if program/ erase fail. Note 2: The value of Bit 0 is "1", no matter the result of program/erase is pass or fail. (3) Clear Status Register This command only resets erase error bit (bit 4) and program error bit (bit 3) . These two bits are set by on-chip state machine during program/erase operation, and can only be reset by issuing a clear status register command or by powering down VCC . If status register indicates that error occurred in the last program/erase operation, any further program/erase operation will be prohibited until status register is cleared. (4) Read ID This command is sent with an extra dummy byte( 2-byte command). The device will clock out manufacturer code (C2H) and device code (9CH) when this command is issued. The clock to clock out the data is supplied by the master SPI. P/N: PM0943 REV. 1.0, SEP. 29, 2004 5 MX25L6402 (5) Sector/Chip Erase This command is sent with the sector address(A22~A16) when operating Sector Erase. The device will start the erase sequence after CS goes high without any further input. A sector should be erased in a typical of 3 sec. The average current is less than 35mA. The chip erase operation does not require the sector address input but two extra dummy bytes are necessary. During this operation, customer can also access Read Status & Read ID operations. (6) Page Program This command is sent with the page number(A22~A7), and 128-byte page address(A6~A0), followed by programming data. The 128-byte page address (A6-A0) must start from 0. One to 128 bytes of data can be loaded into the buffer of the device until CS goes high. User needs to issue a complete last byte data, otherwise the last byte data will be ignored. If the end of the page is reached, then the device will wrap around to the beginning of the page. The device will program the specified page with buffered data(Until CS goes high) without any further input. The typical page program time is 4mS. The average current is less than 35mA. During this operation, customer can also access Read Status & Read ID operations. (7) Standby Mode When CS is high and there is no operation in progress, the device is put in standby mode. Typical standby current is less than 5uA. (8) ACC FAST PROGRAM/ERASE FUNCTIONS When ACC pin is not connected to a 12V power supply, all program and erase current is drawn through the VCC pin. When ACC pin is connected to a 12V power supply, the device draws program and erase current directly from the ACC pin. This eliminates the need for an external switching transistor control the voltage VHH. The 12V ACC mode enhances programming performance during the short period of time typically found in manufacturing processes; however, it is not intended for extended use. ACC pin may be connected to 12V for a total of 80 hours maximum. Stressing the device beyond these limits may cause permanent damage. POWER-ON STATE After power-up, the device is placed in the standby state with following status: The status register is reset with following status : Bit 7 = "1" -----> Refer to page 5 for detail. Bit 6,5,2,1 = Reserve for future use. Bit 4 = "0" -----> Erase error flag is reset. Bit 3 = "0" -----> Program error flag is reset. Bit 0="1" -----> Device is in ready state. P/N: PM0943 6 REV. 1.0, SEP. 29, 2004 MX25L6402 RESET OPERATION The RESET pin provides a hardware method of resetting the device to reading array data. When the RESET pin is driven low for at least a period of tRP, the device immediately terminates any operation in progress, tri-states all output pins, and ignores all commands for the duration of the RESET pulse. The device also resets the internal state machine to reading array data. The operation that was interrupted should be reinitiated once the device is ready to accept another command sequence, to ensure data integrity. Current is reduced for the duration of the RESET pulse. When RESET is held at VSS + 0.3V, the device draws reset current (ICC4). If RESET is held at VIL but not within VSS + 0.3V, the reset current will be greater. The RESET pin may be tied to system reset circuitry. A system reset would that also reset the SPI memory. Refer to the AC Characteristics tables for RESET parameters. DATA SEQUENCE Output data is serially sent out through SO pin, synchronized with the rising edge of SCLK, whereas input data is serially read in through SI pin, synchronized with the rising edge of SCLK. The bit sequence for both input and output data is bit 7 (MSB) first, then bit 6, bit 5, ...., and bit 0.(LSB) ADDRESS SEQUENCE The address assignment is described as follows : BA: Byte address Bit sequence: AD1:First Address Bit sequence: AD2:Second Address Bit sequence: AD3:Thrid Address Bit sequence: X X A16 X A6 X A15 X A5 A22 A14 X A4 A21 A13 X A3 A20 A12 X A2 A19 A11 X A1 A18 A10 A8 A0 A17 A9 A7 P/N: PM0943 7 REV. 1.0, SEP. 29, 2004 MX25L6402 Auto Page Program Flow Chart Auto Chip Erase Flow Chart START START F2H F4H Set Chip Erase AD1 Dummy Command.
