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.
Applications:
• 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)
