Description

The M25PX32 is a 32 Mbit (4 Mb x 8) serial Flash memory, with advanced write protection

mechanisms, accessed by a high speed SPI-compatible bus.

The M25PX32 supports two new, high-performance dual input/output instructions:

●

Dual Output Fast Read (DOFR) instruction used to read data at up to 75 MHz by using

both pin DQ1 and pin DQ0 as outputs

●

Dual Input Fast Program (DIFP) instruction used to program data at up to 75 MHz by

using both pin DQ1 and pin DQ0 as inputs

These new instructions double the transfer bandwidth for read and program operations.

The memory can be programmed 1 to 256 bytes at a time, using the Page Program

instruction.

The memory is organized as 64 sectors that are further divided into 16 subsectors each

(1024 subsectors in total).

The memory can be erased a 4-Kbyte subsector at a time, a 64-Kbyte sector at a time, or as

a whole. It can be Write Protected by software using a mix of volatile and non-volatile

protection features, depending on the application needs. The protection granularity is of 64

Kbytes (sector granularity).

An enhanced Fast Bulk Erase mode is available to speed up Bulk Erase operations in

factory environment. The device enters this mode whenever the VPPH voltage is applied to

the Write Protect/Enhanced Program supply voltage pin (W/VPP).

The M25PX32 has 64 One-Time-Programmable bytes (OTP bytes) that can be read and

programmed using two dedicated instructions, Read OTP (ROTP) and Program OTP

(POTP), respectively. These 64 bytes can be permanently locked by a particular Program

OTP (POTP) sequence. Once they have been locked, they become read-only and this state

cannot be reverted.

In order to meet environmental requirements, ST offers the M25PX32 in ECOPACK®

packages. ECOPACK® packages are Lead-free and RoHS compliant.
