MC68HC705JJ7 Datasheet, PDF (14/164 Pages) Freescale Semiconductor, Inc – Microcontrollers

General Description
• Power-saving stop and wait mode instructions (MOR selectable STOP conversion to halt and
option for fast 16-cycle restart
and power-on reset)
• On-chip temperature measurement diode
• MOR selectable reset module to reset central processor unit (CPU) in low-voltage conditions
• Illegal address reset
• Internal steering diode and pullup device on RESET pin to V_DD
1.3 Device Options
These device options are available:
• On-chip oscillator type: crystal/ceramic resonator connections or resistor-capacitor (RC)
connections
• Nominal frequency of internal low-power oscillator: 100 or 500 kHz
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 Chapter 15 Electrical Specifications.
Combinations of the various device options are specified by part number. Refer to Table 1-1 and to
Chapter 17 Ordering Information for specific ordering information.
