Quick Detail:
fhigh-performance microcontroller units MCUs)
Description:
The M68HC11K Family of high-performance microcontroller units
(MCUs) offers a non-multiplexed expanded bus, high speed and low
power consumption. The fully static design allows operation at
frequencies from dc to 4 MHz.
This manual contains information concerning standard and
custom-ROM (read-only memory) devices. Standard devices include
those replacing the ROM with:
• Disabled ROM
• Disabled EEPROM (electrically erasable, programmable read-only
memory)
• EPROM (erasable, programmable read-only memory)
• OTPROM (one-time progammable read-only memory)
Custom-ROM devices have a ROM array that is programmed at the
factory to customer specifications.
M68HC11K Family devices feature up to 62 input/output (I/O) lines
distributed among eight ports, A through H. The KS Family removes
seven pins from port G and four pins from port H for a total of 51
I/O
lines. The KSx versions feature a slow mode for the clocks to allow
power conservation.
Applications:
M68HC11K Family features include:
• 8-bit opcodes and data
• 16-bit addressing
• Two 8-bit accumulators, which can be concatenated to form one
16-bit accumulator
• On-board memory:
– 24 Kbytes or 32 Kbytes of ROM, EPROM, or OTPROM
– 768 bytes or 1 Kbyte of static RAM (random-access memory)
– 640 bytes of EEPROM
– 128-byte register block
• Dual-function I/O lines — Any pins used for the microcontroller’s
peripheral functions can be configured as general-purpose I/O
lines.
• Non-multiplexed address and data buses
• 68HC11K4 offers:
– 1 Mbyte of address space, using on-chip memory mapping logic
– Four programmable chip selects (expanded modes)
• 16-bit timer system:
– Three input capture (IC) channels, record event timing by storing
the value of the timing system’s 16-bit free-running counter when
an input signal transition occurs.
– Four output compare (OC) channels, provide timed outputs by
signaling when the free-running counter reaches a predetermined
number.
– One IC or OC channel (software selectable)
• 8-bit pulse accumulator
• Four 8-bit pulse-width modulation (PWM) outputs
• Enhanced asynchronous serial communications interface (SCI)
• Enhanced synchronous serial peripheral interface (SPI)
• 8-channel, 8-bit, analog-to-digital (A/D) converter
• Computer operating properly (COP) watchdog system to guard
against infinite loops and other system problems
• Real-time interrupt timer
• Power-saving modes:
– Slow mode reduces power consumption by slowing down
internal operations.
– Wait mode shuts down various system features selected by
the user with power consumption typically dropping to
10–100 mW.
– Stop mode also shuts down system clocks, typically reducing
power consumption to about 1.5 mW.
