Write Buffer Programming time = 120us for 128Mb, 256Mb and 512 (10Q EPNs) and 70n s for 1Gb and 512Mb (11G and 12G EPNs). 4. From CFI Table in Datasheet P/N: AN-0143 4

Write Buffer Length Alignment Write buffer maximum length is different between MX29GL_F and S29GL_S devices. Software modification is necessary for if the longer S29GL_S buffer length is being used. There are two methods for length alignment: (i) Modify write buffer length to 32 words for both devices. (ii) Read the maximum buffer length from CFI offset address 2Ah (word mode) and adjust the algorithm to use this length. Note: Spansion suggests performing buffer writes using multiples of 32-byte pages to maximize data integrity. Macronix provides 32-word buffer writes are in common using for file systems and software algorithms. Page Read Length Alignment MX29GL_F and S29GL_S maximum page read lengths are different. It will be necessary to modify the software if the longer S29GL_S read page length is being used. There are two methods for length alignment. (i) Adjust the page read length in the SoC or controller to 8 words for both devices. (ii) Read the maximum length from CFI offset address 4Ch (word mode) and adjust the SoC or controller setting accordingly. P/N: AN-0143 5

5. DC Characteristics Macronix has improved Write Current power consumption while Read currents are similar (Table 5-1).

Table 5-2 shows that both flash families have similar input sink and output drive characteristics. Table 5-2: Input/Output Voltage DC Characteristic Macronix MX29GL_F Spansion S29GL_S Very High Voltage 9.5V ~ 10.5V N/A Input Low Voltage -0.1V (min..) / 0.3VI/O (max.) -0.5V (min.) / 0.3VI/O (max.)

Notes: VI/O voltage must be same as VCC for Macronix H/L versions and Spansion 01/02 types. P/N: AN-0143 6

6. Command Set and Firmware Basic command sets and write status checking methods are similar between both flash families. While the algorithm descriptions may be slightly different, the concepts are the same. Furthermore, Spansion supports status register checking, which is a new structure in parallel flash and is not backward compatible. Depending on the write status checking method used, the algorithm may require minor modifications. 6.1 Basic Command Table (Word mode) MX29GL_F and S29GL_S have the same basic command set. The Read operation and Write command can be used directly without modification.. Table 4-1 shows the command set in Word mode. Table 6-1: Basic Commands (Word Mode) Command Read Rese t Progra m Write to Buffer Chip Erase Sector Erase Program/Eras e Suspend *6 Program/Era se Resume *6 1 st Bus Addr Addr XXX 555h 555h 555h 555h XXX XXX Cycle Data Data F0h AAh AAh AAh AAh B0h 30h 2 nd Bus Cycle 3 rd Bus Cycle Addr 2AAh 2AAh 2AAh 2AAh Data 55h 55h 55h 55h Addr 555h SA *1 555h 555h Data A0h 25h 80h 80h 4 th Bus Addr Addr SA 555h 555h Cycle Data Data N-1 *2 AAh AAh 5 th Bus Addr WA *3 2AAh 2AAh Cycle Data WD *4 55h 55h 6 th Bus Addr WBL *5 555h SA Cycle Data WD 10h 30h Note: 1. SA: Sector Address 2. N-1: Word Count (Maximum length is different form two series.) 3. WA: Write Address 4. WD: Write Data 5. WBL: Write Buffer Location 6. Spansion provides two command sets for Program Suspend/Resume. Spansion recommends using B0h/30h for Erase suspend/resume, but 51h/50h for Program suspend/resume.macronix use same commands(b0h/30h) for both functions. P/N: AN-0143 7

6.2 Write Status Checking Method When a flash program/erase operation is in progress, either the Polling Method or Toggle Bit Method may be used to monitor the operation. Both are standard algorithms in parallel flash and can be used for both device families. However, Macronix does not support the status register method for checking write status. Polling Method: Polling method checks Q7 (data complement bit) and Q5 (time out bit) values during the operation. After the operation has finished, Q7 will output true Data. Toggle Bit Method: The toggle bit method checks the Q6 (toggle bit) value during writes. When the write operation ends, Q6 will stop toggling. Start Start Read Q7~Q0 at valid address Read Q7~Q0 Twice Q7 = Data#? No Q6 Toggle? No No Yes Q5 = 1? No Yes Q5 = 1? Yes Read Q7~Q0 at valid address Yes Read Q7~Q0 Twice Q7 = Data#? No Q6 Toggle? No Fail Yes Pass Yes PGM/ERS fail Write Reset CMD PGM/ERS Complete P/N: AN-0143 8

7. Manufacturer ID and Device ID Manufacturer IDs are different and permits software to identify the device manufacturer, but Device IDs are the same (Table 7-1). The same command set is used read the different Manufacturer IDs.

Device ID can be read out after Manufacturer ID with proper address and doesn t need another command sequence. 2. Use Reset command (F0h) to return to normal read mode. P/N: AN-0143 9

8. Power on Timing Macronix and Spansion power on sequences are similar, but the timing is slightly different. (Table- 8-1).

10. Summary Macronix MX29GL_F and Spansion S29GL_S Parallel Flash occupy the same PCB footprint and have similar commands, function, and features. Overall, the S29GL_S to MX29GL_F migration will only require minimal software modifications. The Macronix BYTE# signal pin must be pulled high, but this is the only hardware modification required.
