MC68HC705V8 Specification Rev. 2.1
NOTE:
A line over a signal name indicates an active low signal. For example,
RESET is active high and RESET is active low. Any reference to voltage,
current, or frequency specified in the following sections will refer to the
nominal values. The exact values and their tolerance or limits are
specified in SECTION 17 ELECTRICAL SPECIFICATIONS.
1.2
MASK OPTIONS
The following mask options are available:
Sensitivity on IRQ Interrupt, Edge- and Level-Sensitive or Edge-Sensitive
Only
Selectable COP Watchdog System
Selectable Low Voltage Reset (LVR) to Hold CPU in Reset
Selectable STOP Instruction Disable
Selectable on-chip power supply regulator disconnect
Selectable option to allow regulator wakeup on a rising edge of the MDLC
Bus
Selectable option to tie the regulator output to VSS when disabled
These mask options are provided through individual bits within the Mask Option Register
which is located and programmed as part of the EPROM array.
1.3
PIN ASSIGNMENTS
The MC68HC705V8 requires 64 bond pads for all I/O and power supply functions. The
device is available in a 56-pin SDIP package where the 8 A/D channels associated with
Port E are not bonded out (AN8 through AN15). The device is also available in the 68 pin
PLCC and 64-pin QFP packages.
The pin out for the 56-pin SDIP, the 68-pin PLCC, and the 64-pin QFP packages are shown
in the following figures. The pad positions are also shown in the following figures.
