MR27V6441L
64M–Word × 1–Bit Serial Production Programmed ROM (P2ROM)
GENERAL DESCRIPTION
The MR27V6441L is a 64 Mbit Production Programmed Read-Only Memory, which is configured as 67,108,864
word × 1-bit. The MR27V6441L supports a simple read operation using a single 3.3V power supply and a Serial
Peripheral Interface (SPI) compatible serial bus.
The MR27V6441L have data programmed and have functions tested at LAPIS Semiconductor factory. (Using the
DC pins for the programming function is NOT allowed.)
