MX25L6402A
GENERAL DESCRIPTION
The MX25L6402A is a CMOS 67,108,864 bit serial eLite FlashTM Memory, which is configured as 8,388,608 x 8 internally. The MX25L6402A 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 MX25L6402A 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. To increase user's factory throughputs, a parallel mode is provided. The performance of read/program is dramatically improved than serial mode. 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 MX25L6402A utilizes MXIC's proprietary memory cell which reliably stores memory contents even after 100 program and erase cycles.

DEVICE OPERATION
1.Before a command is issued, status register should be checked to ensure device is ready for the intended operation. 2.When incorrect command is inputted to this LSI, this LSI becomes standby mode and keeps the standby mode until next CS falling edge. 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
completion Note1
bit6 parallel mode 1=in parallel 0=not in parallel mode
bit5 NA
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.

(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 2sec. The average current is less than 26mA. 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. 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 2mS. The average current is less than 26mA. 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) Parallel Mode (Highly recommended for production throughputs increasing)
The parallel mode provides 8 bit outputs for increasing throughputs of factory production purpose. The parallel mode requires 55H command code, after writing the parallel mode command and then CS# going high, after that, the eLite FlashTM Memory can be available to accept read/program/read status/read ID command as the normal writing command procedure. The eLite FlashTM Memory will be in parallel mode until VCC power-off. a. Only effective for Read Array, Read Status, Read ID & Page Program write data period. (refer to page 16,18,21,23) b. For normal write command (by SI), No effect c.Under parallel mode, the fastest access clock freq. will be changed to 1.25MHz(SCLK pin clock freq.) d. For parallel mode, the tAA will be change to 50ns.
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 = "0" -----> Device is not in parallel mode. Bit 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.

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

Note: 1. Typical program and erase time assumes the following conditions: 25° C, 3.0V, and all bits are programmed by checkerboard pattern. 2. Under worst conditions of 70° C and 3.0V. Maximum values are up to including 100 program/erase cycles. 3. System-level overhead is the time required to execute the command sequences for the page program command. 4. Excludes 00H programming prior to erasure. (In the pre-programming step of the embedded erase algorithm, all bits are programmed to 00H before erasure)
