• Power saving PLL circuit
• Wired-OR interrupt capability for keyboard support, allowing wake-up from STOP and WAIT
modes
• Two 8- or 9-bit SCI subsystems, one with MI BUS^† capability; both NRZ type for RS232
compatibility
• Two SPI subsystems, with software selectable MSB/LSB first option
• 8-channel, 8-bit analog-to-digital (A/D) converter
• Four 8-bit PWM timer channels (may be concatenated to form one or two 16-bit channels)
• 4-segment LCD driver
• Available in 84-pin PLCC or 112-pin TQFP packages (MC68HC11PH8); also 84-pin
CERQUAD package (MC68HC711PH8)

Mask options
There are five mask options available on the MC68HC11PH8. These options are programmed
during manufacture and must be specified on the order form.
• Security option (available/unavailable); see Section 3.4.4
• PLL oscillator frequency (32kHz/614kHz); see Section 2.5
• Oscillator buffer type (inverter/Schmitt trigger); see Section 2.3
• POR/exit from STOP start-up time (4064/128 bus cycles); see Section 3.3.2.4
• ROMON bit software switchable in user expanded mode (enable/disable); see Section 3.3.2.1
Note:
These options are not available on the MC68HC711PH8; on this device, the security
option is always available, the PLL oscillator is optimized for operation at 32 kHz, the
oscillator buffer is an inverter, the POR/exit from STOP start-up time is 4064 bus cycles
and the ROMON bit is software switchable in user expanded mode.
† The Motorola Interconnect Bus (MI BUS) is a serial communications protocol which supports
distributed real-time control efficiently and with a high degree of noise immunity. It allows data
to be transferred between the MCU and the slave device using only one wire, making this type
of communication suitable for medium speed networks requiring very low cost multiplex
wiring.
