Preliminary
CMOS IC
LC372100PP, PM, PT-10/20LV
2 MEG (262144 words × 8 bits) Mask ROM
Internal Clocked Silicon Gate
Overview
The LC372100PP, LC372100PM and LC372100PT are
262,144-word × 8-bit organization (2,097,152-bit) mask
programmable read only memories.
The LC372100PP-10, LC372100PM-10 and
LC372100PT-10 feature an access time of 100 ns, an OE
access time of 40 ns, and a standby current of 30 µA, and
are optimal for use in 5-V systems that require high-speed
access.
The LC372100PP-20LV, LC372100PM-20LV and
LC372100PT-20LV feature an access time of 200 ns, an
OE access time of 80 ns, and a standby current of 4 µA,
and thus are optimal for use in 3-V systems that use
batteries. Additionally, they provide high-speed access in
3.3-V systems (3.0 to 3.6 V) with a 150-ns access time
and a 60-ns OE access time.
These ROMs adopt the JEDEC standard pin assignment
which allows them to replace EPROM easily. To prevent
bus line collisions in multi-bus microcontroller systems,
pin 24 can be mask programmed to be either active high or
active low.

System Design Notes
These LSIs adopt an internal synchronization technique in which operation is started by detecting changes in either the
CE input or the address inputs. As a result, the output data immediately after power on is invalid. Once power has been
applied, valid data is output after the application changes the value of either the CE input or at least one of the address
inputs.
Another point due to the use of the ATD technique is that these LSIs are extremely sensitive to input noise. Applications
must take precautions to provide stable input signals, both for the CE input and the address inputs, to prevent incorrect
operation.
