詳細說明
General DescriptionIntroductionThis document contains a detailed description of the M68HC11 E series of 8-bit microcontroller units (MCUs). These MCUs all combine the M68HC11 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.FeaturesFeatures of the E-series devices include:• M68HC11 CPU• Power-saving stop and wait modes• Low-voltage devices available (3.0–5.5 Vdc)• 0, 256, 512, or 768 bytes of on-chip RAM, data retained during standby• 0, 12, or 20 Kbytes of on-chip ROM or EPROM• 0, 512, or 2048 bytes of on-chip EEPROM with block protect for security• 2048 bytes of EEPROM with selectable base address in the MC68HC811E2• Asynchronous non-return-to-zero (NRZ) serial communications interface (SCI)• Additional baud rates available on MC68HC(7)11E20• Synchronous serial peripheral interface (SPI)• 8-channel, 8-bit analog-to-digital (A/D) converter• 16-bit timer system: – Three input capture (IC) channels – Four output compare (OC) channels – One additional channel, selectable as fourth IC or fifth OC• 8-bit pulse accumulator• Real-time interrupt circuit• Computer operating properly (COP) watchdog system• 38 general-purpose input/output (I/O) pins: – 16 bidirectional I/O pins – 11 input-only pins – 11 output-only pins• Several packaging options: – 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), MC68HC811E2 only – 56-pin plastic shrink dual in-line package, .070-inch lead spacing (SDIP)
