LC378000RP
Internally Synchronized Silicon Gate 8M (1,048,576-
word × 8-bit, 524,288-word × 16-bit) Mask ROM
Overview
The LC378000RP is an 8-Mbit mask ROM that can be
switched between byte mode, which provides an 8-bit ×
1,048,576-word structure, and word mode, which provides
a 16-bit × 524,288-word structure. Since this device
operates over the wide supply voltage range of 2.6 to
5.5 V and achieves access times (t_AA) of 100 ns (at V_CC =
4.5 to 5.5 V) and 200 ns (at V_CC = 2.6 to 5.5 V), it can be
used in a wide range of systems, from 5-V systems
requiring high-speed access to 3-V battery operated
systems.
