M69AW048B データシート - STMicroelectronics

SUMMARY DESCRIPTION
The M69AW048B is a 32 Mbit (33,554,432 bit) CMOS memory, organized as 2,097,152 words by 16 bits, and is supplied by a single 2.7V to 3.3V supply voltage range.
M69AW048B is a member of STMicroelectronics PSRAM memory family. These devices are manufactured using dynamic random access memory cells, to minimize the cell size, and maximize the amount of memory that can be implemented in a given area.
However, through the use of internal control logic, the device is fully static in its operation, requiring no external clocks or timing strobes, and has a standard Asynchronous SRAM Interface.
The internal control logic of the M69AW048B handles the periodic refresh cycle, automatically, and without user involvement.
