R3200x SERIES
Reset Timer IC for Mobile Equipments
NO.EA-280-190531
OUTLINE
The R3200x is a reset timer IC with two input signals for mobile equipment which require long interval for
reset sequence. The long interval prevents unexpected resets caused by accidental key operations. Internally,
the R3200x consists of a delay generator circuit and output driver transistors.
The R3200x has two active-low input pins (SR0 and SR1) which generate reset signals after output delay time
when both active-low input pins are activated at the same time.
The R3200x has two versions that are different in output delay time settings and output release method.
R3200x001x:
Output delay time is selectable from 7.5 s or 11.25 s typ. by connecting the DSR pin to either GND or VDD. A
reset signal can be released by making one of the active-low input pins high.
R3200xxx2x, R3200L053B or R3200L064A:
Output delay time is fixed. A reset signal will be released automatically after output release time. Or, by
making one of the active-low input pins high, a reset signal can be released before output release time.
The R3200x provides ultra-low supply current while a reset signal is remaining active or after being sent out.
The R3200x is offered in a 8-pin DFN(PLP)2020-8B package or a 8-pin DFN1216-8 package.

ABSOLUTE MAXIMUM RATINGS
Electronic and mechanical stress momentarily exceeded absolute maximum ratings may cause permanent damage and
may degrade the life time and safety for both device and system using the device in the field. The functional operation at
or over these absolute maximum ratings is not assured.
RECOMMENDED OPERATING CONDITIONS (ELECTRICAL CHARACTERISTICS)
All of electronic equipment should be designed that the mounted semiconductor devices operate within the
recommended operating conditions. The semiconductor devices cannot operate normally over the recommended
operating conditions, even if they are used over such conditions by momentary electronic noise or surge. And the
semiconductor devices may receive serious damage when they continue to operate over the recommended operating
conditions.

TECHNICAL NOTES
The performance of power source circuits using this device largely depends on the peripheral circuits. When
selecting the peripheral components, consider the conditions of use. Do not allow each component, PCB
pattern and the device to exceed their respected rated values (voltage, current and power) when designing
the peripheral circuits.
When only one active-low input pins is used (refer to R3200xxxxA Typical Application) connect the
unused one to GND.
In the case of applying the following circuit configuration to the R3200x, the supply current of the device
itself may cause significant voltage drop on the VDD pin if the R1 value is high. As a result, the VDD voltage
may fall below the minimum operating voltage.

When both active-low input pins become the low voltage level, the timer operation starts. After the output
delay time (tdelay), a reset signal will be sent out. When one of the active-low input pins becomes the
high voltage level, the timer operation stops.
During tdealy, if one of the active-low input pins becomes the high voltage level, the timer operation stops.
If both active-low input pins become the low voltage level again, a reset signal will be sent out after
tdelay.
A reset signal will be released if one of the active-low input pins becomes the high voltage level. Until one
of the active-low input pins becomes the high voltage level, a reset signal will be continually sent out.
tdelay can be selected from 7.5 s or 11.25 s typ. by connecting the DSR pin to either GND or VDD.
However, if the DSR pin is switched during the operations, the output would become unstable and may
cause false operations. Switching of the DSR pin must be done during power-off.
Also, the DSR pin must be connected to either GND or VDD, otherwise the output would become unstable
and may cause false operations.

OUTPUT DELAY TIME GAP
The threshold voltages of the active-low input pins are between VIL and VIH. Therefore, if the rising or falling
slew rate is very slow, the timer will start at the point of crossing the threshold voltage and may cause errors in
the output delay time (tdelay) and the output release time (trec).

VDD START-UP DURING LOW INPUT
When starting up VDD at slow slew rate of 0.001 V/µs or less while the active-low input pins are the low voltage
level, the device may start the operation at lower than the minimum operating voltage, thus tdelay may exceed
the guaranteed time.

consent of Ricoh.
3. Please be sure to take any necessary formalities under relevant laws or regulations before exporting or otherwise
taking out of your country the products or the technical information described herein.
4. The technical information described in this document shows typical characteristics of and example application circuits
for the products. The release of such information is not to be construed as a warranty of or a grant of license under
Ricoh's or any third party's intellectual property rights or any other rights.
5. The products listed in this document are intended and designed for use as general electronic components in standard
applications (office equipment, telecommunication equipment, measuring instruments, consumer electronic products,
amusement equipment etc.). Those customers intending to use a product in an application requiring extreme quality
and reliability, for example, in a highly specific application where the failure or misoperation of the product could result
in human injury or death (aircraft, spacevehicle, nuclear reactor control system, traffic control system, automotive and
transportation equipment, combustion equipment, safety devices, life support system etc.) should first contact us.
6. We are making our continuous effort to improve the quality and reliability of our products, but semiconductor products
are likely to fail with certain probability. In order to prevent any injury to persons or damages to property resulting from
such failure, customers should be careful enough to incorporate safety measures in their design, such as redundancy
feature, fire containment feature and fail-safe feature. We do not assume any liability or responsibility for any loss or
damage arising from misuse or inappropriate use of the products.
7. Anti-radiation design is not implemented in the products described in this document.
8. The X-ray exposure can influence functions and characteristics of the products. Confirm the product functions and
characteristics in the evaluation stage.
9. WLCSP products should be used in light shielded environments. The light exposure can influence functions and
characteristics of the products under operation or storage.
10. There can be variation in the marking when different AOI (Automated Optical Inspection) equipment is used. In the
case of recognizing the marking characteristic with AOI, please contact Ricoh sales or our distributor before attempting
to use AOI.
11. Please contact Ricoh sales representatives should you have any questions or comments concerning the products or
the technical information.
