What is Aplus' embedded OTP?
OTP stands
for One Time Programmable EPROM. It utilizes the traditional UV-EPROM
process technology and is programmed by the CHE (Channel Hot Electron)
scheme. Program operation can be performed based on byte (8 bits)
or Word (16 bits) basis or N-bits for a customized design. Currently
our 0.5um 2P2M2W EPROM leading design technology is in production
in several foundries worldwide as is our 0.35um 2P2M2W EPROM.
What product applications can embedded OTP be used for?
- OTP embedded
library block can be used for high-performance 8bit, 16bit or
N-bit embedded OTP micro-computer applications such as speech
synthesizers, LCD micro-controllers, instant voice recorders
and many others.
- For all
embedded markets requiring extremely low power consumption (i.e.
< 20uA @ 5 volts) operating at very low frequencies.
What
are the advantages of using Aplus' embedded OTP?
- Wide
range of operation - Aplus' OTP EPROM
can operate in the widest Vdd window ranging from 2.4V to 6V
in read operation. The VPP programming voltage of 12V or below
is designed to be fully compatible with the traditional EPROM
programmer, achieving larger breakdown margins. The unique circuit
design achieves high programming yield and speed for wide Vdd
operation. The maximum number of programming bits can be up
to 32 bits for fast turnaround time.
- Low-power
circuit design - Completely shuts off DC current consumption
when any address transitions do not occur within 1000ns, typically.
Further reduces the operating current below 10uA when operating
at 32768 Hz clock operation, in battery-based consumer applications.
When the memory block is disabled by CEB, a standby mode is
entered with zero DC current consumption.
- Increased
Security -A security bit design is incorporated onto the
chip, offering secure protection over the pirated copying of
OS code after programming.
