Comparison of MX25U8033E/4033E/2033E with MX25R8035F/4035F/2035F

APPLICATION NOTE
Comparison of Macronix 25U Series
with 25R Serial Flash
(For 2Mb/4Mb/8Mb)
1. Introduction
This application note compares Macronix 2Mb, 4Mb and 8Mb 1.8V/Wide Range VCC Serial NOR Flash.
Generally, the MX25R2035F/4035F/8035F are similar with MX25U2033E/4033E/8033E as they are pin and
command compatible with the basic Read/Program/Erase commands. MX25R2035F/4035F/8035F provides
wider voltage range and lower power consumption.
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 Section "9. Reference". Newer
versions of the datasheets may override the contents of this document.
2. General Features
Macronix 2Mb/4Mb/8Mb, 1.8V/Wide Range VCC serial flash families have similar features and functions as
shown in the table below.
MX25R2035F/4035F/8035F provide wider voltage range and 4Kb x 2 of Secured OTP size.
For Block Protection, MX25R2035F/4035F/8035F and MX25U2033E/4033E/8033E can all use BP bit to
protect content in memory. But MX25R series have T/B bit which make slight different and easier to protect
than MX25U series.
