APPLICATION NOTE Replacing Spansion® S34ML02G100 with Macronix MX30LF2G18AC 1. Introduction This application note is a guide for migrating to the Macronix MX30LF2G18AC from the Spansion® S34ML02G100 2Gb, 3V, NAND flash memory. The document does not provide detailed information on the individual devices, but highlights the major similarities and differences between them. The comparison covers the general features, performance, command codes and other differences. The information in this document is based on datasheets listed in Section 10. Newer versions of the datasheets may override the contents of this document. 2. Features Both flash device families have similar features and functions as shown in Table 2-1. The primary difference is that the Macronix device requires 4-bit ECC, whereas the Spansion device only requires 1-bit ECC.

Package Pin/Ball Definition Package physical dimensions are similar to each other. For detailed information, please refer to the individual datasheets. Table 5-1 and 5-2 shows differences in pin assignments between the Macronix and Spansion devices. The S34ML02G100 can be replaced by the MX30LF2G18CA without pin conflicts. Only 48-TSOP pin #38 (63-VFBGA ball G5) may need special attention because the pin is designated “PT” which is Chip Protected function on the MX30LF2G18AC-TI.

Read ID Command The ID of the Macronix MX30LF2G18AC begins with a one-byte Manufacturer Code followed by a four-byte Device ID. While the same command set is used to read the Manufacturer ID, Device ID, and flash structure, the IDs are different, allowing software to identify the device manufacturer and device type (Table 7-1).

Power-Up Timing Macronix and Spansion® power-up sequences are similar, but the timing is slightly different. Although both devices use 2.7V (VCC min.) as the start point, timing references are different. Check the system timing to determine if adjustments are needed.

Because basic Read/Program/Erase commands as well as block, page, and spare area sizes are the same, device migration may require minimal or no firmware modifications to accommodate differences in ECC requirements.
