MCP3913

The MCP3913 parts you have received conform

functio nal ly t o the De vi ce Data She et (DS2000522 7A),

except for the anomalies described in this document.

All of the issues discussed will be addressed in future

revisions of the MCP3913 silicon.

Silicon Errata Issues

1. Module: ADC Conversion

The converter internal phases can be erroneously

generate d if ther e is a simult ane ous occurre nce of

a mast er clo ck ed ge and a res et ev ent (a RES ETn

pin risi ng ed ge , the last SCK rising edge of a w ri te

communication that generates an ADC reset and

restart, as defined in Section 6.6 Situations that

Reset and Restart Active ADCs, or a Power-on

Reset). This perturbation in the internal clock

phase’ s generation can cause modulator instability

and generate erroneous results, therefore, it is

highly recommended these events are not

synchronized.

Work around

A possi ble workaround of t his issue is to freeze the

master clock during all the above-detailed events

(a RESETn pin rising edge, the last SCK rising

edge of a write communication that generates an

ADC reset and restart, as defined in Section 6.6

Situations that Reset and Restart Activ e ADCs,

or a Power-on Reset). In this case, the part will not

exhibit any issues.

Note the following details of the code protection feature on Microchip devices:

• Microchip products meet the specification contained in their particular Microchip Data Sheet.

• Microchip believes that it s family of products is one of the most secure families of its kind on the market today, when used i n t he

intended manner and under normal conditions.

• There are dishonest and possibly illegal m e thods used to breach the code protection feature. All of these methods, to our

knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip’s Data

Sheets. Most likely, the person doing so is engaged in theft of intellec tual property.

• Microchip is willing to work with the customer who is concerned about the integrity of their code.

• Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code. Code protection does not

mean that we are guaranteeing the product as “unbreakable.”

Code protection is c onstantly evolving. We a t Microc hip are co m mitted to continuously improving the code prot ect ion featur es of our

products. Attempts to break Microchip’ s code protection feature may be a violation of the Digital Millennium Copyright Act. If such acts

allow unauthorized access to your software or other copyrighted work, you may have a right to sue for relief under that Act.

Microchip received ISO/TS-16949:2009 certification for its worldwide

headquarters, design and wafer fabrication facilities in Chandler and

Tempe, Arizona; Gresham, Oregon and design centers in California

and India. The Company’s quality system processes and procedures

are for its PIC® MCUs and dsPI C® DSCs, KEELOQ® code hopping

devices, Serial EEPROMs, microperiph erals, nonvolatile memory and

analog products. In addition, Microchip’s quality system for the design

and manufacture of development systems is ISO 9001:2000 certified.
