M25PX64-VMF6P FLASH - NOR Memory IC 64Mbit SPI 75 MHz 16-SO

Description

The M25PX64 is a 64-Mbit (8 Mbits x 8) serial flash memory, with advanced write protection mechanisms,

accessed by a high speed SPI-compatible bus.

The M25PX64 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 128 sectors that are further divided into 16 subsectors each (2048 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).

The M25PX64 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.

Further features are available as additional security options. More information on these security features is

available, upon completion of an NDA (nondisclosure agreement), and are, therefore, not described in this

datasheet. For more details of this option contact your nearest Numonyx sales office.
