TK68HC11K1 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 These devices have been replaced by the pin-for-pin compatible KS2.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

TK68HC11K1 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
