1 Comparison of 73F/36F and MX25L32xxD/xxE 1. Introduction This application note compares Macronix 75nm 32Mb 3V Serial NOR Flash 73F/36F with Macronix 110nm flash MX25L3235E and MX25L3206/8E and Macronix 150nm flash MX25L32xxD. Generally, the 73F/36F is backward compatible with the MX25L32xxD/xxE as it is pin and command compatible with the basic Read/Program/Erase commands. There may be some differences if special features are used such as using QPI commands, Write Protection, or CP programming. The comparison covers the general features, performance, command codes, and other differences. The document does not provide detailed information on individual devices, but highlights major differences. The information in this document is based on the latest datasheets listed in "8. Reference". Newer versions of the datasheets may override the contents of this document. 2. General Features Macronix 3V 32Mb Serial NOR Flash families have similar features and functions as shown in "Table 2-1. Key Features Comparison". Table 2-1.

5 5. Register Comparison APPLICATION NOTE The 73F/36F Status Register bits are backward compatible with the registers of the MX25L32xxD/E, with the exception of the MX25L3225D which has volatile bits which default with the memory array protected at power-up.

The 73F/36F Configuration Register bits are backward compatible with the registers of the MX25L323xE, with the exception bits 6 and 7 of the 3235E and 3233F which can be used to set the number of dummy cycles when executing a 4READ command. If the default number of dummy cycles is used, then this difference can be ignored.

6 6. Data Protection 6-1. BP bit Block Protection All of the listed Macronix flash use BP bits to select groups of memory areas for write protection. The 73F and 39E/73E have the ability to write protect identical groups of blocks with the same BP bit settings. Most of the regions protected by the /08E/36F and MX25L32xxD can be protected by the MX25L3233F ("Table 6-1: Block Protection (BP) with T/B bit = 0").

Individual Sector Protection The 39E/73E has the ability to protect individual 4KB and 64KB sectors and blocks of memory. The 73F/36F and /08E, MX25L32xxD do not support this feature. P/N: AN0325 6

7 7. Device Identification The RDID instruction is for reading the 1-byte Manufacturer ID followed by the 2-byte Device ID.
