3. ELECTRICAL SPECIFICATIONS (G: INDUSTRIAL APPLICATIONS TA = –40 to

+105°C)

This chapter describes the following electrical specifications.

Target products G: Industrial applications TA = -40 to +105°C

R5F102xxGxx

Cautions 1. The RL78 microcontrollers have an on-chip debug function, which is provided for development and

evaluation. Do not use the on-chip debug function in products designated for mass production,

because the guaranteed number of rewritable times of the flash memory may be exceeded when this

function is used, and product reliability therefore cannot be guaranteed. Renesas Electronics is not

liable for problems occurring when the on-chip debug function is used.

2. The pins mounted depend on the product. Refer to 2.1 Port Functions to 2.2.1 Functions for each

product in the RL78/G12 User’s Manual.

3. Please contact Renesas Electronics sales office for derating of operation under TA = +85°C to

+105°C. Derating is the systematic reduction of load for the sake of improved reliability.

Remark When the RL78 microcontroller is used in the range of TA = -40 to +85°C, see 2. ELECTRICAL

SPECIFICATIONS (TA = -40 to +85°C).

There are following differences between the products “G: Industrial applications (TA = -40 to +105°C)” and the products “A:

Consumer applications, and D: Industrial applications”.
