Why use the PTC01
The PTC01 has been optimized specifically for
calibration of Melexis PTC devices. It was designed
as a cost e ffective replacement for high priced
ATEs.
programmers to quickly create custom software on
any platform. The PTC01 was designed to meet
the requirements of most sensor applications and
adapt to most production environments. Please
contact Melexis for support if any additional
requirements are necessary.
General Description
The PTC-01 programmer w as specifically designed
to program the Melexis family of programmable
sensor ICs. At the heart of the programmer is a
microprocessor which generates the two-channel
level
programming. The programmer can generate two
independent precision waveforms from 0-20V such
as needed for programming Melexis linear Hall ICs.
Hall IC digital patterns are included in the standard
firmware release which is pre-loaded
volatile RAM at the factory. Melexis also uses the
PTC-01 hardware as a hardware platform for some
other Melexis ASIC products, which require special
firmware, not included in the standard release.

com.
Communication
The PTC-01 programmer uses a standard serial
interface with RS-232 protocol. Connection to the
communications port is done with a null modem
cable to a standard COM port (see page 8).
Because the standard is RS-232, the PTC-01 is not
limited to any a particular platform. The firmware
commands can be executed in any language which
permits serial communications.

Linear Power Supply
The high current switching supplies of the SDAP-02
are replaced with a single 300mA 24V linear supply.
The result is lower noise in the analog circuitry. The
PTC-01 can be used with the 24V supply as above,
or can be connected to an external 24V and 5V
precision supply if desired. The external supply
option allows the user to utilize precision voltage
supplies which may be already implemented in an
existing test platform. (This is illustrated on page 6.)
Optimized Firmware
The PTC-01 has utilized the firmware to help make
some common tasks more efficient. Firmware
functions are used for voltage measurements,
current measurements, and return multiple sets of
data.
software development and reduce test time.
Further details can be found in the PTC-01 software
documentation.
Versatile Design
The programmer’s phys ical design has been
greatly improved for flexibility and portability. The
integrated device socket is mounted to the top of the
unit for convenience.
connected to the programmer via the RJ45
connector to allow remote calibration. Since the
PTC-01 has been entirely constructed onto a single
PC board, the unit can be stripped of its plastic
case and mounted into a card rack or chassis
easily.
PC Requirements
The PTC-01 requires a PC capable of RS-232
serial communications of 19200 baud.

processor with 8MB of RAM and 4MB of available
disk space.
