Errata Sheet

May 29, 1998 / Release 1.1

Device: SAK-C167CR-LM

SAK-C167CR-L25M

Stepping Code / Marking:

ES-DB, DB

Package:

MQFP-144

This Errata Sheet describes the deviations from the current user documentation. The
classification and numbering system is module oriented in a continual ascending sequence
over several derivatives, as well already solved deviations are included. So gaps inside this
enumeration could occur.

The current documentation is: Data Sheet: C167CR-4RM Data Sheet 07.97,

C167SR/CR-L25M Data Sheet Addendum 1998-03

User’s Manual: C167 Derivatives User’s Manual V2.0 03.96
Instruction Set Manual 12.97 Version 1.2

Note: 

Devices marked with EES- or ES are engineering samples which may not be

completely tested in all functional and electrical characteristics, therefore they should
be used for evaluation only.

The specific test conditions for EES and ES are documented in a separate Status Sheet.

Change summary to Errata Sheet Rel.1.0 for devices with stepping code/marking
ES-DB:

  Modifications of ADM field while bit ADST = 0 (ADC.11)

  P0H spikes after XPER write access and external 8-bit Non-multiplexed bus (X12)

  ADC Overload Current (ADCC.2)

  DC specification deviations added, limit for I

P0L

 =  –110 µA added

  AC timing relaxations added, t5 (ALE high time) tested according to specification
