68HC16 Module
________________General Description
The 68HC16 module is an assembled and tested print-
ed-circuit board intended for use with Maxim’s high-
speed serial-interface evaluation kits (EV kits). The
module uses an inexpensive 8-bit implementation of
Motorola’s MC68HC16Z1 microcontroller (μC) to collect
data samples at high speed using the QSPI interface.
It requires an IBM-compatible personal computer and
an external DC power supply, typically 12V DC or as
specified in EV kit manual.
Maxim’s 68HC16 module is provided to allow customers
to evaluate selected Maxim products. It is not intended
to be used as a microprocessor development platform,
and such use is not supported by Maxim.
QSPI is a trademark of Motorola Corp.

________________Detailed Description
Power Input Connector J2
The 68HC16 module draws its power from a user-sup-
plied power source connected to terminal block J2. Be
sure to note the positive and negative markings on the
board. A three-terminal 5V regulator allows input voltages
between 8V and an absolute maximum of 20V. The
68HC16 module typically requires 200mA of input current.
68HC16 Microcontroller
U1 is Motorola’s 68HC16Z1 μC. Contact Motorola for μC
information, development, and support. Maxim EV kits use
the high-speed queued serial peripheral interface (QSPI)
and the internal chip-select generation.
A MAX707 on the module monitors the 5V logic supply,
generates the power-on reset, and produces a reset
pulse whenever the reset button is pressed.
