General Description
1.1 Introduction
This section depicts the general characteristics and features of the MC68HC711D3 high-density
complementary metal-oxide semiconductor (HCMOS) microcontroller unit (MCU).
The MC68HC711D3 contains highly sophisticated on-chip peripheral functions. This high-speed,
low-power programmable read-only memory (PROM) MCU has a nominal bus speed of 3 MHz. The fully
static design allows operations at frequencies down to dc.
The MC68HC11D3 and MC68HC11D0 are read-only memory (ROM) based high-performance
microcontrollers (MCU) based on the MC68HC11E9 design. The MC68L11D0 is an extended-voltage
version of the MC68HC11D0 that can operate in applications that require supply voltages as low as 3.0 V.
The information in this document pertains to all the devices with the exceptions noted in Appendix A
1.2 Features
Features of the MC68HC711D3 include:
Expanded 16-bit timer system with four-stage programmable prescaler
Non-return-to-zero (NRZ) serial communications interface (SCI)
Power-saving stop and wait modes
64 Kbytes memory addressability
Multiplexed address/data bus
Serial peripheral interface (SPI)
4 Kbytes of one-time programmable read-only memory (OTPROM)
8-bit pulse accumulator circuit
192 bytes of static random-access memory (RAM) (all saved during standby)
Real-time interrupt (RTI) circuit
Computer operating properly (COP) watchdog system
Available in these packages:
40-pin plastic dual in-line package (DIP)
44-pin plastic leaded chip carrier (PLCC)
44-pin plastic quad flat pack (QFP)
