1 GENERAL DESCRIPTION

1.1 INTRODUCTION

The ST6208L/09L/10L/20L are low voltage mask
programmed ROM version of ST62T08C/T09C/
T10C/T20C OTP devices.

They offer the same functionality as OTP devices,
selecting as ROM options the options defined in
the programmable option byte of the OTP version,
with the exception of the LVD Reset that is not
available.

Figure 1. Programming wave form

1.2 ROM READOUT PROTECTION

If the ROM READOUT PROTECTION option is
selected, a protection fuse can be blown to pre­vent any access to the program memory content.

In case the user wants to blow this fuse, high volt­age must be applied on the TEST pin.

1.3 ORDERING INFORMATION

The following section deals with the procedure for
transfer of customer codes to SGS-THOMSON.

1.3.1 Transfer of Customer Code

Customer code is made up of the ROM contents
and the list of the selected mask options. The
ROM contents are to be sent on diskette, or by
electronic means, with the hexadecimal file gener­ated by the development tool. All unused bytes
must be set to FFh.

The selected mask options are communicated to
SGS-THOMSON using the correctly filled OP­TION LIST appended.

1.3.2 Listing Generation and Verification

When SGS-THOMSON receives the user’s ROM
contents, a computer listing is generated from it.
This listing refers exactly to the mask which will be
used to produce the specified MCU. The listing is
then returned to the customer who must thorough­ly check, complete, sign and return it to
SGS-THOMSON. The signed listing forms a part
of the contractual agreement for the creation of the
specific customer mask.

The SGS-THOMSON Sales Organization will be
pleased to provide detailed information on con­tractual points.

2 ELECTRICAL CHARACTERISTICS

2.1 ABSOLUTE MAXIMUM RATINGS

This product contains devices to protect the inputs
against damage due to high static voltages, how­ever it is advisable to take normal precaution to
avoid application of any voltage higher than the
specified maximum rated voltages.

For proper operation it is recommended that V

I

and VObe higher than VSSand lower than VDD.
Reliability is enhanced if unused inputs are con­nected to an appropriate logic voltage level (V

DD

or VSS).

Power Considerations.The average chip-junc­tion temperature, Tj, in Celsius can be obtained
from:

Tj=TA + PD x RthJA

Where:TA = Ambient Temperature.

RthJA =Package thermal resistance(junc-

tion-to ambient).
PD = Pint + Pport.
Pint =IDD x VDD (chip internal power).
Pport =Port power dissipation(determined

by the user).

Notes:

- Stresses above those listed as “absolute maximum ratings” may cause permanent damage to thedevice. This is a stress ratingonly and
functional operation of the device at these conditions is not implied. Exposure to maximum rating conditions for extended periods may
affect device reliability.

- (1) Withinthese limits,clamping diodes are guarantee to be not conductive. Voltages outside these limits are authorised as longas injection
current is kept withinthe specification.

2.2 RECOMMENDED OPERATING CONDITIONS

Notes:

1. Care must be taken in case of negative current injection, where adapted impedance must be respected on analog sources to not affect the

A/D conversion. For a -1mA injection, a maximum 10 KΩ is recommended.

2.An oscillator frequency above 1MHz is recommended for reliable A/D results
