The M18 family with synchronous PSRAM stacked product family encompasses multiple
M18 flash memory plus synchronous PSRAM die combinations and I/O interface options.
M18 is available as a Non-Multiplex or Address-Data Multiplex (AD-Mux) I/O interface option,
while the synchronous PSRAM is available only as a Non-Multiplex I/O interface.
The M18 is the latest generation of Numonyx™ StrataFlash® memory with highlighted features
like symmetrical block array, configurable burst lengths, automated device blank check, security
using OTP and zero-latency block lock. The M18 delivers up to 133 MHz synchronous burst and
page-mode read rates with multi-partitioning Read-While- Program and Read-While-Erase
operations. The synchronous PSRAM (Non-Mux I/O interface) is a high-performance volatile
memory operating at speeds up to 104 MHz with configurable burst lengths. The PSRAM lower
sixteen addresses can be routed to the data pins on the PCB board to enable a flexible flash and
PSRAM AD-Mux I/O interface device design. This stacked device family features configurable
output driver strength and 1.8 volt low-voltage operation in an Numonyx™ Flash memory x16C or
QUAD+ standard footprint and signal ball outs.
