• Manufacturer Part Number: MC68HC711PH8
• Description: High-density Complementary Metal Oxide Semiconductor (HCMOS) Microcomputer Unit
• Manufacturer: Motorola

The MC68HC11PH8 8-bit microcontroller is a member of the M68HC11 family of HCMOS
microcontrollers. In addition to 48K bytes of ROM, the MC68HC11PH8 contains 2K bytes of RAM
and 768 bytes of EEPROM. Making use of an 84-pin PLCC, or 112-pin TQFP package, a
non-multiplexed expanded bus is a feature of this device. The timer system has been expanded to
include three input captures, four output compares and a software selectable input capture or
output compare. There are three 8-bit modulus timers, one of which may be used as a prescaler
for the other two. The inclusion of a PLL circuit allows power consumption and performance to be
adjusted to suit operational requirements. Other major features of this device are: 8-channel, 8-bit
A/D converter, four PWM timer channels, wired-OR capability for keyboard interrupt, four LCD
segment drivers and two SPI and two enhanced SCI subsystems. The MC68HC11PH8 is
especially suitable for mobile communications and automotive applications.
The MC68HC711PH8 is an EPROM version of the MC68HC11PH8, with the user ROM replaced
by a similar amount of EPROM. All references to the MC68HC11PH8 apply equally to the
MC68HC711PH8, unless otherwise noted. References specific to the MC68HC711PH8 are
italicised in the text.
