Issue Date: Oct. 01, 2008
GENERAL DESCRIPTION
The MR37V12841A is a 128Mbit Production Programmed Read-Only Memory, which is configured as
134,217,728word  1-bit. The MR37V12841A supports a simple read operation using a single 3.3V power supply
and a Serial Peripheral Interface (SPI) compatible serial bus.
The MR37V12841A have data programmed and have functions tested at LAPIS Semiconductor factory. (Using
the DC pins for the programming function is NOT allowed )
