Mask Set Errata 3
MC68HC711E9 8-Bit Microcontroller Unit
INTRODUCTION
This mask set errata provides information pertaining to the V
PPE
pin programming
current sensitivity applicable to this MC68HC711E9 MCU mask set device:
•
H50W
MCU DEVICE MASK SET IDENTIFICATION
The mask set is identified by a 5-character code consisting of a version number, a
letter, two numerical digits, and a letter, for example 3J74Y. Slight variations to the
mask set identification code may result in an altered version number, for example
4J74Y.
MCU DEVICE DATE CODES
Device markings indicate the week of manufacture and the mask set used. The
data is coded as four numerical digits where the first two digits indicate the year
and the last two digits indicate the work week. For instance, the date code “9915”
indicates the 15th week of the year 1999.
MCU DEVICE PART NUMBER PREFIXES
Some MCU samples and devices are marked with an SC or XC prefix. An SC prefix
denotes special/custom device. An XC prefix denotes that the device is tested but
is not fully characterized or qualified over the full range of normal manufacturing
process variations. After full characterization and qualification, devices will be
marked with the MC prefix.
When contacting a Motorola representative for assistance, please have the MCU
device mask set and date code information available.
Specifications and information herein are subject to change without notice.

PIN PROGRAMMING CURRENT SENSITIVITY
During EPROM programming of the MC68HC711E9 device, the V
PPE
pin circuitry
may be damaged if the input current is not limited to 10 mA.
Programming the EPROM without an input current limit may destroy the
programming functionality. This condition has been experienced on various
programming systems (including in-circuit programming) where no current limit on
the V
PPE
pin exists.
Workaround:
It has been found that limiting the current to the XIRQ/V
PPE
pin with a 1-kΩ resistor
can protect the EPROM voltage circuit even when the voltage is bouncing on V
PPE
and will allow enough current to program the EPROM array.
