TK68HC711E20 Microcontroller

General Description

The TK68HC11 E series are 8-bit microcontroller units (MCUs). These MCUs all combine the TK68HC11 central processor unit (CPU) with high-performance, on-chip peripherals.

The E series is comprised of many devices with various configurations of:

Random-access memory (RAM)
Read-only memory (ROM)
Erasable programmable read-only memory (EPROM)
Electrically erasable programmable read-only memory (EEPROM)
Several low-voltage devices are also available.

With the exception of a few minor differences, the operation of all E-series MCUs is identical. A fully static design and high-density complementary metal-oxide semiconductor (HCMOS) fabrication process allow the E-series devices to operate at frequencies from 3 MHz to dc with very low power consumption.

Pin Descriptions

TK68HC11 E-series MCUs are available packaged in:

52-pin plastic-leaded chip carrier (PLCC)
52-pin windowed ceramic leaded chip carrier (CLCC)
52-pin plastic thin quad flat pack, 10 mm x 10 mm (TQFP)
64-pin quad flat pack (QFP)
48-pin plastic dual in-line package (DIP), TK68HC811E2 only
56-pin plastic shrink dual in-line package, .070-inch lead spacing (SDIP)
