Package Pin/Ball Definition Package physical dimensions are similar to each other. For detailed information, please refer to the individual datasheets. Tables 5-1 and 5-2 show differences in pin assignments between the Macronix and Spansion devices. The S34ML04G200 can be replaced by the MX30LF4G18CA without pin conflicts. Only 48-TSOP pin #38 (63-VFBGA ball G5) may need special attention because the pin is designated “PT” which, if high during power-up, enables a memory protection function on the MX30LF4G18AC. The PT pin can be left unconnected as it has a weak internal pull-down to disable the protection feature.

Read ID Command The ID of the Macronix MX30LF4G18AC 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 are the same, device migration may require minimal firmware modifications primarily due to differences in spare area sizes.
