■ HANDLING DEVICES
1. Preventing Latchup
Latch-up may occur in a CMOS IC if a voltage greater than VCC or less than VSS is applied to an input or output
pin, or if an above-rating voltage is applied between VCC and VSS. A latchup, if it occurs, significantly increases
the power supply current and may cause thermal destruction of an element. When you use a CMOS IC, be very
careful not to exceed the absolute maximum rating.
2. Treatment of N.C. pins
Be sure to use NC pins in open state.
3. Rising time for power supply voltage
Ensure that the power supply rise time is 100 µs or less when using contact mode operation but, which may
cause misoperation resulting in the corruption of FRAM data.
4. Power supply off time
Ensure that the power supply off time is 1ms or longer when using contact mode operation.
5. Magnetic field strength rise time
See the “■ RF INTERFACE in CONTACTLESS OPERATION” section for points to note regarding contactless
operation.
6. When using both contact and contactless operation
When operating in contact mode, ensure there is no RF input from the antenna. When operating in contactless
mode, ensure that the contact terminals are open circuit.

■ RF INTERFACE in CONTACTLESS OPERATION
1. Flow at carrier ON
Communications between PICC (card) and PCD (R/W) is based on a "PCD Talk First" protocol in accordance
with the procedure described below.
(1) RF power is supplied to PICC by the magnetic field generated by PCD.
(2) PICC is able to receive within 5 ms of RF power on.
(3) PICC waits with no response until receiving a command from PCD (receive standby state).
(4) PCD sends a command to PICC (sent approx. 10 ms after RF power on).
(5) PICC executes the operation specified by the PCD instruction and sends a response to PCD on completion.
• Time standard at carrier ON
5 ms (Max)
2 ms (Max)
Carrier ON
PICC : ASK reception enabled
100 µs to 500 µs
2. Power supply
(1) Carrier frequency fc : 13.56 MHz ± 7 kHz
(2) PICC operating magnetic field strength (when not modulated) : 4.0 A/m to 7.5 A/m
12
MB94R215B
3. Interface of signal
(1) Data transmission from PCD to PICC
• Communication speed fb : 105.9375 Kbps / 211.8750 Kbps
• Method of modulation type : ASK
• Modulation level m :
PICC : 8.0% to 14.0%
PCD : 30/H1.2 (mVpeak)
• Bit coding
Logic “1” : High magnetic field amplitude (with no modulation)
Logic “0” : Low magnetic field amplitude
The modulation level m is defined by the formula m = (a − b) / (a + b) as shown in the figure below. Here, a and
b are the maximum and minimum amplitudes of the magnetic field strength generated by PCD. The rising and
falling edges of these amplitude changes are monotonic. The transition times are 1 µs or less.
• Definition of modulation level

v = 0.2 × (a − b)

(2) Data transmission from PICC to PCD
• Communication speed fb : 105.9375 Kbps (fc/128)
• Method of data transmission : Load Modulation
PCD always sends logic “1” during data transfer from PICC.
• Load modulation sub-carrier frequency fs : 847.5 kHz (fc/16)
• Method of sub-carrier modulation : BPSK
Phase changes occur at valid timings on the sub-carrier rise and fall.
The sub-carrier fs is modulated by the data using BPSK modulation. The carrier fc is further amplitude
modulated by the phase-changed sub-carrier.
• Bit coding : NRZ-L
• Load Modulation load resistance : Modulation circuit resistance 150 Ω

MB94R215B
4. Notes on carrier
When handling the device for the contactless IC cards, observe the following to prevent the improper operation
or damage to the device. Keep in mind, however, that the transmission characteristics are dependent on the
antenna design and reader/writer characteristics, so the values below are only for reference and the values
below are not intended to guarantee the finished card characteristics. Ensure that operation and transmission
characteristics have no problems in the environments where you use a card.
(1) Rising of carrier
Ensure that the carrier rise time is in the range 100 µs to 500 µs and that the carrier rises continuously with a
deviation of ± 2.4% or less.
• Rising waveform of carrier
Deviation = (A − B) / (A + B)
A
B
Rising Time = 100 µs to 500 µs
(2) Falling of carrier
Ensure that the carrier fall time is in the range 100 µs to 100 ms and that the carrier falls continuously with a
deviation of ± 2.4% or less.
• Falling waveform of carrier
Deviation = (A − B) / (A + B)
B
A
Falling time = 100 µs to 100 ms
14
MB94R215B
(3) Stop of carrier
The MB94R215B has internal capacitance to smooth the power supply and similar. Accordingly, always provide
a gap of 100 ms or longer between halting and restarting the carrier to allow the internal state to stabilize.
• Stop time of carrier
Carrier stop
time ≥ 100 ms
(4) Carrier deviation (noise, momentary stop, etc.)
Ensure that the deviation when not modulated is ± 2.4% or less. The following problems may occur if variation
(noise) in excess of this limit occurs.
• If the carrier falls within the ASK modulation level range (8 to 14%), this may be misinterpreted as a modulation signal. However, if the frame is determined to be invalid, the command receive block will be cleared and
the device will return to the command standby state.
• If the carrier variation exceeds the ASK modulation level range in the region 0 A/m to 12 A/m, misoperation
may occur and internal circuits may reset. In this case, temporarily turn off the carrier in accordance with the
precautions in "(3) Stop of carrier". If the carrier is not turned off, misoperation may corrupt internal data.
• If the carrier exceeds the ASK modulation level range over 12A/m, the device may be damaged due to the
increase in internal voltage.
• Carrier deviation
12 A/m

Deviation = (C − D) / (C + D) × 100

MB94R215B
(5) Operating conditions
Contactless devices (cards) can only be used in a one-to-one communication with a reader/writer. Do not try to
use the MB94R215B embedded card to a reader/writer with multiple other contactless cards. Use of multiple
contactless devices may corrupt data or cause the device to misoperate.
Using the device in the presence of strong magnetic fields (12 A/m or stronger) or with reader/writers that do
not match the specifications may cause data corruption.
