Figure 1. Low Power Shift-Out IntelliHead
INTRODUCTION
MagTek’s Low Power Sh ift-Out IntelliHead consists of a high-performance multi-channel fully
integrated magnetic stripe decoder chip encapsulated within a low-profile magnetic read-head. The
Low Power Shift-Out IntelliHead is designed for battery operated devices that need to “wake from
swipe”. It features a typical quiescent current when armed to accept a swipe of only 1.5 μA. If this
low quiescent current is not needed, then cost savings can be realized by using the regular Shift-Out
IntelliHead. See MagTek specification 99875258 for details.
Note that the Low Power Shift-Out IntelliHead is limited to reading cards that have at least track 2
encoded. This is because it keys off of track 2 only for its “wake-up” signal. If track 2 is encoded,
the other encoded tracks (track 1 and/or track 3) will also be read.
FEATURES
• Ultra-low Sleep or Armed-to-Read current – only 1.5 μA typical current when no card is
being swiped. Ideal for battery-powered readers.
• Ultra-compact design – low-profile read head contains all needed circuits. Save PCB space!
• No external components – even the decoupling capacitor is integrated. Only 4 signals, VDD,
VSS, DATA, and STROBE to connect to your micro-controller for up to 3 tracks
• Data buffer with Shift-Out – allows full card data to be locally stored on ASIC. Use a low-
power controller with interrupt on swipe, limited memory, low-speed, low pin-count, etc.
• High noise immunity – no analog signals leave the shielded magnetic head! Withstands noisy
PC monitors, cell phones, switching power supplies, etc.
• High performance decoding – new design reads badly damaged cards; compensates for poor
head mounting
• Robust re-synchronization capabilities – reads cards with badly damaged leading or
synchronization zero-bits in either swipe direction
• Low voltage operation – 2.85 V to 3.6 V
• Low operating current – less than 1.2 mA maximum total current at 3.3V (for up to 3 tracks)
while card is being swiped
• AGC (Automatic Gain Control) – reads cards from 30% - 200% of ISO 7811 amplitude
standard
• Wide operational temperature range – -40 °C to +85 °C
• Wide range of card swipe speeds – from 6 ips to 100 ips (15 cm/s to 250 cm/s)
• ROHS Compliant – “lead (Pb) free” component

Low Power Shift-Out IntelliHead
SHIFT-OUT PROTOCOL
Refer to MagTek specification 99875337 for details of the Shift-Out Protocol. The Low Power
Shift-Out IntelliHead functions identically to the regular Shift-Out IntelliHead, except as noted
in this document. This document (99875349) takes precedence over 99875337.
The exact same Shift-Out protocol (New Mode) for the regular Shift-Out IntelliHead may also be used
for the Low Power Shift-Out IntelliHead. To take advantage of the low power feature, though, a
special protocol must be followed. This special protocol delays the reset sequence by 300 ms, so it can
be advantageous to use the regular Shift-Out protocol when a quick re-arm time is desired. This is
typically the case for insert or dip type readers. A quick reset is needed if it is desired to read on
withdrawal of the card. Note that this imposes no penalty on battery life, since after the card
withdrawal, the IntelliHead may be put back into the low power armed-to-read state with the special
protocol.
To put the unit in its special low power armed-to-read state, after STROBE is taken high entering the
OFF state as a part of the reset sequence, delay at least 300 ms, and then take STROBE from its high
state to a high-impedance state (high-Z). The unit is now in its special low power armed-to-read state,
although the Delta ASIC internal to the Low Power IntelliHead is in its OFF state.
When in the special low power armed-to-read state, the Low Power IntelliHead will only respond to
the track 2 signal for “wake-up”. Once “awakened”, tracks 1 and/or 3 will be read if encoded. Cards
that do not have track 2 encoded will not read reliably. They may read sometimes due to som e DC
magnetization of the intended blank track 2 stripe causing a sufficiently large signal to trip the “wakeup” circuit.
From the special low power armed-to-read state, STROBE will fall when a card is detected. STROBE
will remain low for at least 100ms1. The user’s micro-controller must actively drive STROBE low
(even though it is being driven low by the IntelliHead) within this 100ms window. STROBE should
be push-pull now until it is again set to high-Z at the end of the next special reset sequence. If the
100ms window is missed, indeterminate operation may result, and another reset should be performed.
From the falling edge of STROBE signaling the beginning of a card swipe, the MCU must hold
STROBE low and wait for DATA to fall, indicating the Card-Present (CP) condition. If there is no CP
within 30ms, a reset should be performed. If CP is seen within 30ms, then operation should proceed
as detailed in 9875337 for the remainder of the shift-out sequence.
The information below is needed for the firmware designer to assign the memory-tracks of the ASIC
(A, B, and C) to the physical magnetic head tracks (1, 2, and 3).
The on-chip memory tracks of the Low Power Shift-Out IntelliHead are permanently assigned to
particular tracks of the magnetic head via internal wires connecting the head coil wires to particular
inputs of the built-in ASIC. As it is oriented in Figure 3, tracks ‘A’, ‘B’, and ‘C’ of the internal ASIC
correspond to tracks ‘1’, ‘2’, and ‘3’ of the reader respectively. The IntelliHead may be mounted with
the opposite orientation if desired, but firmware must anticipate this re-mapping of ASIC memory
tracks to physical magnetic head tracks.

If compatibility with the future MagnePrint™ Low Power IntelliHead is desired, a 25 μs window should be respected
instead of a 100 ms window. MagnePrint is a security feature that can distinguish counterfeit cards from the original card.

CURRENT CONSUMPTION †
Note: Refer to the timing diagrams in 99875337 for complete information.
Iarm = 120 μA maximum
Iswipe = 1.2 mA maximum (internal oscillator running)
Iextract = 20 μA maximum
Cstrb = [1 nF maximum + parasitic capacitance of PCB] (this is the total capacitance driven by
STROBE and its effects; sometimes called power-dissipation-capacitance)
Fstrb = User-controlled frequency of STROBE during data extraction
IdataLow = 48 μA maximum
Irst_int = 1.2 mA maximum (internal oscillator running; subtract IdataLow if DATA is released
before Irst_int expires)
Ioff = 1.5 μA typical at 25 °C; 13 μA maximum at 85 °C (STROBE drive leakage into MCU
not included)
Example calculation for current consumption during New Mode data extraction:
Maximum parasitic PCB capacitance on STROBE (example) = 20 pF
Cstrb = 1 nF + 20pF
Fstrb = 1MHz
VDD = 3.3 V
Imax = Iextract + Fstrb * Cstrb * VDD
Imax = (20 μA) + (1 MHz) * (1020 pF) * (3.6 V)
Imax = 3.7 mA
Notes:
1) The duration of Iarm is very brief when using the low power armed-to-read feature. It
exists only from the time STROBE falls at the beginning of a card, until the time that the
ASIC is able to recognize the card. This duration is one bit-cell maximum (swipe speed
dependent).
2) When treating this unit as a regular Shift-Out IntelliHead, an additional current of up to
190uA will exist in the armed-to-read state (Iarm) due to a 20 kΩ nominal pull-up in the
Low Power Shift-Out IntelliHead. Except in the armed-to-read state, this 20 kΩ nominal
resistor may be a pull-up or pull-down depending upon actual head signals.

SHIFT-OUT TIMING
Refer to MagTek specification 99875337 for details of the Shift-Out Timing. The following exception
exists for the IntelliHead in contrast to the ASIC specification given in 99875337.
Trst (Reset) = 1.5 ms minimum (not shown in timing diagram)
VDD off-time to guarantee a reset for the ASIC/Head unit. This is due to an RC power supply filter
inside the head.
Other differences exist when using the special low power armed-to-read state. These are detailed in
the SHIFT-OUT PROTOCOL section above.

connect the head case ground directly to a separate earth ground if possible, bypassing the closely
spaced PCB connector terminals. If this is not possible, as is the case in many designs, then the
next best thing is to pass the earth ground through the board on its way to earth. Tying earth
