TK68HC711KS2 Microcontroller

 

General Description

TK68HC11K 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 are derived from the KAx version and feature a slow mode for the clocks to allow power conservation. Table 1-1 lists devices currently available in the K Family along with their distinguishing features.

NOTE:    Tekmos no longer offers the KA2 and KA4 devices. These devices have been replaced by the pin-for-pin compatible KS2.

Features

TK68HC711KS2 is a member of the TK68HC11K 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:
    • 32 Kbytes or 48 Kbytes of ROM, EPROM, or OTPROM
    • 768 bytes, 1 Kbyte, or 1.5 Kbytes 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
  • 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
