The M48Z128Y-85PM1 is a high-performance general-purpose static random access memory (SRAM) for microcontroller and digital signal processor applications. It is fabricated using a 0.85μm CMOS process and has a nominal operating voltage range of 1.65 V to 5.5 V. This device is capable of reaching Read access times of 15ns and Write access times of 20ns at 3.3 V.

The M48Z128Y-85PM1 is organized as 128K × 8 bits and is available in a 48-pin TSOP, 48-ball Fine-Pitch BGA, and 48-pad Fine-Pitch QFP packages. The device is equipped with industry-standard active−low chip-enable (CE#) and write−enable (WE#) pins, providing both independent (CE1#) and simultaneous (CE2#) Read and Write functions. With a write−protect (WP#) input, the device supports both software and hardware write−protection methods. The device also supports a number of advanced features, including an automatic power−down (APD) mode and an output enable (OE#) pin for 3-state operation.

The M48Z128Y-85PM1 memory application fields are quite extensive, from automotive electronics applications to general embedded system applications such as data loggers or controllers. This device can be used to store firmware, configuration data, sensor readings, and other program instructions.
