The device provide the high density MTP memory solution with reliable performance and most cost-effective. The device organized as by 8 bits or by 16 bits of output bus. The device is packaged in 44-Lead SOP. It is designed to be reprogrammed and erased in system or in standard EPROM programmers. The device offers fast access time and allowing operation of high-speed microprocessors without wait states. The device augment EPROM functionality with in-circuit electrical erasure and programming. The device uses a command register to manage this functionality. The MXIC's Nbit technology reliably stores memory contents even after the specific erase and program cycles. The MXIC cell is designed to optimize the erase and program mechanisms by utilizing the dielectric's character to trap or release charges from ONO layer. The device uses a 3.0V to 3.6V VCC supply to perform the High Reliability Erase and auto Program/Erase algorithms. The highest degree of latch-up protection is achieved with MXIC's proprietary non-epi process. Latch-up protection is proved for stresses up to 100 milliamps on address and data pin from -1V to VCC + 1V.

The Write State Machine (WSM) controls block erase and word/page program operations. Operational modes are selected by the commands written to the Command User Interface (CUI). The Status Register indicates the status of the WSM and when the WSM successfully completes the desired program or block erase operation. STANDBY When CE disable the device (see table1) and place it in standby mode. The power consumption of this device is reduced. Data input/output are in a high-impedance(HighZ) state. If the memory is deselected during block erase, program or lock-bit configuration, the internal control circuits remain active and the device consume normal active power until the operation completes. READ The device has three read modes, which accesses to the memory array, the Device Identifier or the Status Register. The appropriate read command are required to be written to the CUI. Upon initial device powerup or after exit from powerdown, the device automatically resets to read array mode. In the read array mode, low level input to CE and OE, high level input to WE and address signals to the address inputs (A22-A-1) output the data of the addressed location to the data input/output (Q15~Q0). When reading information in read array mode, the device defaults to asynchronous page mode. In this state, data is internally read and stored in a high-speed page buffer. A2:0 addresses data in the page buffer. The page size is 4 words or 8 bytes. Asynchronous word/byte mode is supported with no additional commands required. WRITE Writes to the CUI enables reading of memory array data, device identifiers and reading and clearing of the Status Register. The CUI is written when the device is enable, WE is active and OE is at high level. Address and data are latched on the earlier rising edge of WE and CE. Standard micro-processor write timings are used. OUTPUT DISABLE When OE is at VIH, output from the devices is disabled. Data input/output are in a high-impedance(High-Z) state.

Bus operations are defined in Table 1. 2. X = Any valid address within the device. BA = Address within the block. IA = Identifier Code Address: see Figure 2 and Table 13. QA = Query database Address. PA = Address of memory location to be programmed. RCD = Data to be written to the read configuration register. This data is presented to the device on A15~A0 ; all other address inputs are ignored. 3. ID = Data read from Identifier Codes. QD = Data read from Query database. SRD = Data read from status register. See Table 14 for a description of the status register bits. PD = Data to be programmed at location PA. Data is latched on the rising edge of WE. CC = Configuration Code. 4. The upper byte of the data bus (Q8-Q15) during command writes is a "Don't Care" in x16 operation. 5. Following the Read Identifier Codes command, read operations access manufacturer, device and block lock codes. See Section 4.3 for read identifier code data. 6. If the WSM is running, only Q7 is valid; Q15-Q8 and Q6-Q0 float, which places them in a high impedance state. 7. After the Write to Buffer command is issued check the XSR to make sure a buffer is available for writing. 8. The number of bytes/words to be written to the Write Buffer = N + 1, where N = byte/word count argument. Count ranges on this device for byte mode are N = 00H to N = 1FH and for word mode are N = 0000H to N =000FH. The third and consecutive bus cycles, as determined by N, are for writing data into the Write Buffer. The Confirm command (D0H) is expected after exactly N + 1 write cycles; any other command at that point in the sequence aborts the write to buffer operation. Please see Figure 4. "Write to Buffer Flowchart" for additional information. 9. The write to buffer or erase operation does not begin until a Confirm command (D0h) is issued. 10.Attempts to issue a block erase or program to a locked block. 11.Either 40H or 10H are recognized by the WSM as the byte/word program setup. 12.The clear block lock-bits operation simultaneously clears all block lock-bits.

The read configuration register defaults to asynchronous read page mode. The device remains enabled for reads until another command is written. DEVICE OPERATION SILICON ID READ The Silicon ID Read mode allows the reading out of a binary code from the device and will identify its manufacturer and type. This mode is intended for use by programming equipment for the purpose of automatically matching the device to be programmed with its corresponding programming algorithm. This mode is functional over the entire temperature range of the device. To activate this mode, the two cycle "Silicon ID Read" command is requested. (The command sequence is illustrated in Table 3. During the "Silicon ID Read" Mode, manufacturer's code (MXIC=C2H) can be read out by setting A0=VIL and device identifier can be read out by setting A0=VIH. To terminate the operation, it is necessary to write the read command. The "Silicon ID Read" command is valid only when the WSM is off. Table 3.

P/N:PM0990 REV. 1.0, OCT. 29, 2003 11 MX26L12811MC READ STATUS REGISTER COMMAND The Status Register is read after writing the Read Status Register command of 70H to the Command User Interface. Also, after starting the internal operation the device is set to the Read Status Register mode automatically. The contents of Status Register are latched on the later falling edge of OE or the first edge of CE that enables the device OE must be toggle to VIH or the device must be disable before further reads to update the status register latch. WRITE TO BUFFER COMMAND To program the device, a Write to Buffer command is issue first. A variable number of bytes, up to the buffer size, can be loaded into the buffer and written to the MTP device. First, the Write to Buffer Setup command is issued along with the Block Address (see Figure 3, Write to Buffer Flowchart on page 15). After the command is issued, the extended Status Register (XSR) can be read when CE is VIL. XSR.7 indicates if the Write Buffer is available. If the buffer is available, the number of words/bytes to be program is written to the device. Next, the start address is given along with the write buffer data. Subsequent writes provide additional device addresses and data, depending on the count. After the last buffer data is given, a Write Confirm command must be issued. The WSM beginning copy the buffer data to the MTP array. If an error occurs while writing, the device will stop writing, and status register bit SR.4 will be set to a "1" to indicate a program failure. The internal WSM verify only detects errors for "1" that do not successfully program to "0" . If a program error is detected, the status register should be cleared. Any time SR.4 and/or SR.5 is set, the device will not accept any more Write to Buffer commands. Reliable buffered writes can only occur when VCC is valid. Also, successful programming requires that the corresponding block lock-bit be reset. CLEAR STATUS REGISTER COMMAND The Erase Status, Program Status, Block Status bits and protect status are set to "1" by the Write State Machine and can only be reset by the Clear Status Register command of 50H. These bits indicates various failure conditions. BLOCK ERASE COMMAND Automated block erase is initiated by writing the Block Erase command of 20H followed by the Confirm command of D0H. An address within the block to be erased is required (erase changes all block data to FFH). Block preconditioning, erase, and verify are handled internally by the WSM (invisible to the system). The CPU can detect block erase completion by analyzing the output of status register bit SR.7. Toggle OE, CE to update the status register. The CUI remains in read status register mode until a new command is issued. BYTE/WORD PROGRAM COMMANDS Byte/Word program is executed by a two-command sequence. The Byte/Word Program Setup command of 40H is written to the Command Interface, followed by a second write specifying the address and data to be written. The WSM controls the program pulse application and verify operation. The CPU can detect the completion of the program event by analyzing the STS pin or status register bit SR.7. Successful byte/word programs require that the corresponding block lock-bit be cleared. If a byte/ word program is attempted when the corresponding block lockbit is set, SR.1 and SR.4 will be set to "1". P/N:PM0990 REV. 1.0, OCT. 29, 2003 12 MX26L12811MC Read Configuration The device will support both asynchronous page mode and standard word/byte reads. No configuration is required. Status register and identifier only support standard word/byte single read operations. Table 6.

To set the block lock-bit, the two cycle Set Block Lock-Bit command is requested. This command is invalid while the WSM is running or the device is suspended. Writing the set block lock-bit command of 60H followed by confirm command and an appropriate block address. After the command is written, the device automatically outputs status register data when read. The CPU can detect the completion of the set lockbit event by analyzing the STS pin output or status register bit SR.7. Also, reliable operations occur only when VCC is valid. Clear Block Lock-Bits Command All set block lock-bits can clear by the Clear Block LockBits command. This command is invalid while the WSM is running or the device is suspended. To Clear the block lock-bits, two cycle command is requested . The device automatically outputs status register data when read. The CPU can detect completion of the clear block lock-bits event by analyzing status register bit SR.7. If a clear block lock-bits operation is aborted due to VCC transitioning out of valid range, block lock-bit values are left in an undetermined state. A repeat of clear block lock-bits is required to initialize block lock-bit contents to known values. VCC--TRANSITIONS Block erase, program, and lock-bit configuration are not guaranteed if VCC falls outside of the specified operating ranges. The CUI latches commands issued by system software and is not altered by CE transitions, or WSM actions. Its state is read array mode upon power-up, after exit from power-down mode, or after VCC transitions below VLKO. P/N:PM0990 REV. 1.0, OCT. 29, 2003 14 MX26L12811MC Figure 3.
