Freescale MC68HC11 training: MC68HC(7)11E(A)9
The MC68HC711E9 high-density complementary metal-oxide semiconductor (HCMOS) high performance microcontroller units (MCUs). It is an erasable ROM (EPROM)-based version of the MC68HC11E9 and includes similar features -12 Kbytes of EPROM, 512 bytes of electrically erasable programmable ROM (EEPROM) and 512 bytes of RAM. The MC68HC711E9 with integrated multiplexed bus is a high speed, low power IC capable of running at up 3 Mhz.
CPL-PCBUG11C hardware for any member of MC68HC11 family
The PCBUG11is a software package allows an IBM PC or compatible to access and simple experimentation with MC68HC11
microcontroller unit devices. It is a MS-DOS hosted program and works on PCs running under MS-DOS,Win95/98 operation systems,
version 3.24. The PCBUG11 software modified by Checkpoint LAB to allow end users run it under
fast PCs and newest operation systems Win2000/WixXP/Win7 *(drivers required).
This program can be used with any programming hardware that has
the capability to boot HC11 chips into the bootstrap mode and
has the required programming voltages and a serial port interface.
CPL-PCBUG11C hardware designed especially to run under PCBUG11 software package.
CPL11E9 programming adapter is designed to access MC68HC7(11)E0/E1/E9/E20 devices in 52 PLCC packages.
CPL11EA9 programming adapter is designed to access MC68HC7(11)EA9 devices in 52 PLCC packages.
Note: Before power ON board! - Install jumper MODA/MODB to bootstrap mode before using 11E9 programming
In ISP mode pay attention to the target board layout.
In case of necessary cut routes to pins MODA/MODB from board and connect pins directly to GND.
SECURITY FEATURE: ALL EEPROM DATA WILL BE LOST IF MCU CONFIGURED TO ENTERING IN BOOTSTRAP MODE AFTER POWER ON RESET!
For more information about bootstrap mode see this document (pages 209-213):
Explore MC68HC711E9 (5C47M) and MC68HC711EA9 (0D46J) from EWS3.
*NOTE: Apply 14.8-16 VDC to the CPL-PCBUG11 hardware for EEPROM programming mode.
Before running the PCBUG11c software under WinXP/Vista/7, it must be adapted by users.
Porttalk driver must be installed into Windows/System32/Drivers folder and Porttalk key must be added to the
