Serial Flash runs faster

Edited by the Electronicstalk editorial team Aug 30, 2007

32Mbit serial Flash device with dual I/O guarantees high-speed performance in digital flat panel and set-top-box applications.

Available now from STMicroelectronics, the M25PX32 is a 32Mbit serial Flash device with dual I/O.

Whereas the company's existing M25PE family devices feature high granularity, the new M25PX family stands out thanks to its guaranteed high-speed performance.

Digital flat panels and set-top-boxes are among the applications that will benefit from the improved performance and technological features of the M25PX32, such as execute-in-place (XiP) features: in digital flat panels, the XiP produces increased interaction for the user; and in set-top-boxes, the improvement can be seen in the turn-on speed, where high-speed downloading of the code to RAM offers faster system power up.

On a larger scale, the M25PX32 brings added value to all applications requiring higher densities, such as personal computers, optical disk drives and printers.

Produced using mature 0.11um process technology, the M25PX32 represents the natural evolution of the M25P subsector Serial Flash family.

In addition to guaranteed performance over its full operating temperature range, the M25PX32 promises high reliability.

Designed to address the needs of applications requiring higher clock frequencies, the device guarantees 75MHz support over the entire 2.7 to 3.6V supply voltage range and through the -40 to 85C industrial temperature range.

The dual I/O is also significant: during the fast read phase, the dual output command allows the system to double the data transfer bandwidth, effectively clocking the NOR at the equivalent of 150MHz, again over the full voltage range; finally, in the fast program phase both the input and output pins are used for programming the memory.

In addition to device-security features such as protection after power up, the device also features an additional 64byte user-lockable, one-time programmable (OTP) area, and the possibility to set the memory as read-only.

Samples of the M25PX32 in S08W, the ultrathin MLP8 5 x 6mm and SO16W packages, are available now, with volume production planned for Q4 2007.

Budgetary pricing is estimated at US $1.55 in 10,000 piece quantities.
