Description
IRMCK203 is a high performance digital motion control IC for Sensorless AC permanent magnet motor application. Control is
based on closed loop vector control for sinusoidal Back EMF motors. With IRMCK203, the users can readily build a high
performance Sensorless drive system without any programming effort and minimum start-up time. Built-in unique start-up and
ramping algorithm enables wide application. This IC is versatile enough that the users can configure and optimize system
performance according to the needs of each application. With International Rectifier iMOTION products including high voltage
ICs such as IR2175 current sensing IC and IRAM series of Intelligent IGBT module in combination with IRMCK203, the end
result is a fully optimized system with reduced electronics component counts. This simplifies the design for low cost Sensorless
drive modules. IRMCK203 can be easily adapted to various permanent magnet motors through ServoDesignerTM tool, which is

IRMCK203
Overview
IRMCK203 is a new International Rectifier integrated circuit device designed for one-chip solution for complete
closed loop current and velocity control of a high performance Sensorless drive for PM motors. Unlike a traditional
microcontroller or DSP, IRMCK203 does not require any programming to complete complex Sensorless algorithm
development. Combined with International Rectifier's high voltage gate drive and current sensing IC, the user can
implement complete speed control of PM motors with minimum component count and virtually no design effort. In
addition to Sensorless closed loop speed control operation, features such as Start-up retry, Phase Loss detection,
Low Loss PWM, Regeneration Braking control and various drive protections are all implemented inside
IRMCK203. Analog and digital I/Os can also be configured. Host communication logic contains Asynchronous
Communication Interface for RS232C or RS422 communication interface, a fast slave SPI interface and an 8 bit
wide Host Parallel Interface. All communication ports have the same access capability to the host register set. The
users can write to, and read from the predefined registers to configure and monitor the drive through these
communication ports.

Configurable parameters are provided to tailor design to various applications (motor and load). These configurable
parameters can be modified via the host register interface through the communication interface. In the IRMCK203
product, a design spread sheet is provided to aid the user for ease of drive start-up, the spread sheet will input high
level application data such as motor name plate information, max speed, current limit, speed and current regulator
bandwidth, base on this information the program will generate the required configurable parameters. Detail on Drive
commissioning is described in the IRMCK203 Application Developer’s Guide.
All logic and algorithms are pre-programmed, and the user does not need to make any effort to develop code,
alleviating the tedious design process. If needed, the user can configure the drive to tailor the control per specific

The values of the R/C will vary based on actual PCB attributes, and some empirical analysis may be required to get the
PLL to start oscillating. Once oscillating, verify that the signal waveform at the OSC1CLK and OSC2CLK pins are
sinusoidal rather than trapezoidal. Refer to Table 1 for suggested R/C values. Most low-cost crystals can be used
in this application. An example is a Citizen Part number CM309B33.333MABJT available from Digi-Key under
part number 300-4160-1-ND.

Make all connections between CHGO, Rp, Cp, Cs and LPVSS as short as possible. Create the underlining shield by
“copper filling” a larger area in the signal plane of the PCB. Connect this shield to the LPVSS pin of the IC. Do
not connect this shield to signal ground (VSS).

PLL Reset
There are two reset pins on the IC, XPD and RESETN both low true. XPD holds the PLL circuitry in reset when
low. Upon XPD going high, the PLL circuitry begins to lock onto the 33.33 MHz clock input. The PLL circuit
may take up to 1 msec to become stable. RESETN asserted low holds the internal DSP logic in reset. Upon
RESETN going high, the IC digital logic becomes active.
RESET should be held low during and at least 1 ms after XPD goes high false to hold the internal logic in reset while
the PLL becomes stable.

IRMCK203
Appendix A
Host Register Map
Register Access
A host computer controls the IRMCK203 using its slave-mode Full-Duplex SPI port, a standard RS-232 port or a 8-bit
parallel port for connection to a microprocessor. All interfaces are always active and can be used interchangeably,
although not simultaneously. Control/status registers are mapped into a 128-byte address space.
Host Parallel Access
The IRMCK203 contains an address register that is updated with the Host Register address when HPA = 1. After
each subsequent data byte is either read or written, the internal address register is incremented. The diagram below
shows that Data Bytes 0 to N would access register locations initially specified by the Address Byte. The Address
Byte with the HPA signal can be asserted at any time.
Address Byte
Data Byte 0
HPA = 1
HPA = 0
…………….
Data Byte N
HPA = 0
HPA = 0
Host Parallel Data Transfer Format
SPI Register Access
When configured as an SPI device read only and read/write operations are performed using the following transfer
format:
Command Byte
Data Byte 0
…………….
Data Byte N
Data Transfer Format
7
6
Read
Only
5
Bit Position
4
3
2
1
0
Register Map Starting Address
Command Byte Format
Data transfers begin at the address specified in the command byte and proceed sequentially until the SPI transfer
completes. As in the Host Parallel Access, the internal address register is incremented after each SPI byte is
transferred. Note that accesses are read/write unless the “read only” bit is set.
RS-232 Register Access
The IRMCK203 includes an RS-232 interface channel that provides a direct connection to the host PC. The software
interface combines a basic "register map" control method with a simple communication protocol to accommodate
potential communication errors.
This document is the property of International Rectifier and may not be copied or distributed without expressed consent.
31
IRMCK203
RS-232 Register Write Access
A Register write operation consists of a command/address byte, byte count, register data and checksum. When the
IRMCK203 receives the register data, it validates the checksum, writes the register data, and transmits and
acknowledgement to the host.

The following example shows a command sequence sent from the host to the IRMCK203 requesting a two-byte

0x02
Byte count of register data is 2
0x00
Data byte 1
0x04
Data byte 2
0x35
Checksum (sum of preceding bytes, overflow discarded)
A good reply from the IRMCK203 would appear as follows:
0x2F
Write completed OK at offset 0x2F
0x2F
Checksum
An error reply to the command would have the following format:
0xAF
Write at offset 0x2F completed in error
0xAF
Checksum

IRMCK203
RS-232 Register Read Access
A register read operation consists of a command/address byte, byte count and checksum. When the IRMCK203
receives the command, it validates the checksum and transmits the register data to the host.

The following example shows a command sequence sent from the host to the IRMCK203 requesting four bytes of read
register data:
0xA0
Read operation beginning at offset 0x20 (high-order bit selects read operation)
0x04
Requested data byte count is 4
0xA4
Checksum
A good reply from the IRMCK203 might appear as follows:
0x20
Read completed OK at offset 0x20
0x11
Data byte 1
0x22
Data byte 2
0x33
Data byte 3
0x44
Data byte 4
0xCA
Checksum
An error reply to the command would have the following format:
0xA0
Read at offset 0x20 completed in error
0xA0

RS-232 Timeout
The IRMCK203 receiver includes a timer that automatically terminates transfers from the host to the IRMCK203 after
a period of 32 msec.

Field Description
Gate drive dead time in units of system clock cycles (e.g., 30 ns
with 33 MHz clock).
Space vector modulator scale factor. This register, which
depends on the PWM carrier frequency, should be set as follows:
W
ModScl = PwmPeriod * sqrt(3) * 4096 / 2355
where PwmPeriod is the value in the PwmConfig write register
group’s PwmPeriod register.
W
This parameter provides a guard band (scaling: 1 = 30nsec) such
that PWM switching will not migrate into the current feedback
sampling instant (Sync Pulse region). This guard band is provided
to improve feedback noise. The parameter only applies to the 3phase Space Vector modulation scheme. Please do not modify
this parameter without consulting a motor drive FAE.

EepromControl Registers (Write Registers)
At power up, the write registers can be optionally initialized with values stored in EEPROM. The EepromControl
write register group and EepromStatus read register group are used to read and write these EEPROM values. Since
the EeAddrW write register (which selects the EEPROM offset to read or write) does not require initialization at
power up, the location corresponding to that register in EEPROM (at offset 0x5D) is used to store a register map
version code. At power on, the IRMCK203 initializes the write registers from EEPROM only if the version code
stored at this offset in EEPROM matches its internal register map version code (which can be read from the
RegMapVer field of the EepromStatus read register group).
To enable write register initialization at power up, write the appropriate register map version code to EEPROM at
offset 0x5D. To disable write register initialization at power up, write a zero (or any non-matching version code) to
offset 0x5D of the EEPROM.

Field Description
This parameter provides the adjustment to the sampling instant for
determination of start failure. The sampling instant starts when
Closed_Loop = 1. Scaling 1 count = 1.966 msec. Please do not
modify this parameter without consulting a motor drive FAE.
During motor start-up, dc current is injected to the motor for
maximization of startup torque per ampere rating. ParkTm controls
the duration of dc current injection. However, users are able to use a
longer duration after two or more restarts by setting this parameter
(ParkTmRet scaling 255 = 4 secs.). This is done to increase the
chance of a successful start-up.Start-up failure may be caused by
increased shaft friction. After first start-up retry, the parking time can
be increased to improve parking performance.
The low flux threshold level for determining a successful startup
(scaling: 129 = 100% flux). Please do not modify this parameter
without consulting a motor drive FAE.The low flux threshold level for
determining a successful startup.
The upper flux threshold level for determining a successful startup
(scaling: 64 = 100% flux). Please do not modify this parameter
without consulting a motor drive FAE.The high flux threshold level for
determining start-up failure.
If start-up fails, the user can program start-up retrial. This parameter
determines the number of start-up retries. A value of zero will disable
startup retrial. The maximum number of retries is 15.
During motor start-up, dc current is injected to the motor for
maximization of startup torque per ampere rating. Users are able to
use a higher level of dc current injection (ParkIRet scaling 255 =
Motor Rated Amp * 0.866) after two or more restarts. This is done to
increase the chance of a successful start-up.Start-up failure may be
caused by increased shaft friction. After first start-up retry, the
parking current can be increased to improve parking performance.

Zero Speed fault. When speed is less than MinSpd/2 (half
minimum speed) for a continuous period of 2 4 seconds, the zero
speed fault will be set.
Start-up retry fault. After a certain number (determined by parameter
NumRetries) of start-up failures, this fault will be set.
Phase loss fault. Drive to motor phase connection may be loose.

Field Description
EEPROM Data Register. Contains the data from the last EEPROM
read operation. Note that writing to the EeRst field in the
EepromControl write register group invalidates this register.
EEPROM Address read register shows the value stored in EEPROM
at the offset of the EeAddrW write register (0x5D). Since this
address in the EEPROM contains the BPIRMCK203 register map
version, the user can read this field to determine whether or not the
write registers were initialized at power on.
