STMicroelectronics (ST) has leveraged its advanced non-volatile memory technology to deliver an industry first with two new 512kb devices that offer the highest density memories available in the industry-standard 2x3x0.6mm 8-pin Micro Leadframe Package (MLP). Pin compatibility with memories of lower density allows designers to upgrade products quickly and efficiently by changing devices without redesigning the board.
The new devices are the M95512 featuring a 20MHz SPI port, and the M24512 with an I2C interface supporting 400kHz Fast-mode or 1MHz Fast-mode Plus. With its 20MHz SPI interface, the M95512 achieves data transfer speeds equal to the fastest serial EEPROMs currently available.
The devices’ built-in byte-mode erasing capability allows easy parameter update; and 128-byte page write, together with 5ms write time, results in rapid programming of assembled boards on the production line.
In addition, with read current as low as 2mA and stand-by current less than 5µA, the new memories save energy in power-sensitive equipment such as battery-powered personal media devices or professional portable instruments. The wide operating-voltage range, from 1.8V to 5.5V, allows the same device to be used across many applications and product variants. Both types are also offered with an operating range of 2.5V to 5.5V.
