Differences Between Conventional-specification Products and Expanded-specification Products

The differences between the conventional-specification products (μPD78F05xx, 78F05xxD) and expanded-

specification products (μPD78F05xxA, 78F05xxDA) of the 78K0/Kx2 microcontrollers are described below.

• A/D conversion time

• X1 oscillator characteristics

• Instruction cycle, peripheral hardware clock frequency, external main system clock frequency, external main

system clock input high-level width, and external main system clock input low-level width (AC characteristics)

• The number of flash memory rewrites and retention time

• Processing time of the self programming library

• Interrupt response time of the self programming library

For details, see 1.1 Differences Between Conventional-specification Products (μPD78F05xx, 78F05xxD) and

Expanded-specification Products (μPD78F05xxA, 78F05xxDA).

Purpose

This manual is intended to give users an understanding of the functions described in the

Organization below.

Organization

The manual for the 78K0/Kx2 microcontrollers is separated into two parts: this manual and

the instructions edition (common to the 78K0 microcontrollers).

User’s Manual

(This Manual)

78K/0 Series

User’s Manual

Instructions

• Pin functions

• Internal block functions

• Interrupts

• Other on-chip peripheral functions

• Electrical specifications

• CPU functions

• Instruction set

• Explanation of each instruction

How to Read This Manual It is assumed that the readers of this manual have general knowledge of electrical

engineering, logic circuits, and microcontrollers.

• When using this manual as the manual for (A) grade products and (A2) grade products of

the 78K0/Kx2 microcontrollers:

→Only the quality grade differs between standard products and (A), (A2) grade products.

Read the part number as follows.

• μPD78F05xx→ μPD78F05xx(A), 78F05xx(A2)

• μPD78F05xxA→ μPD78F05xxA(A), 78F05xxA(A2)

• To gain a general understanding of functions:

→ Read this manual in the order of the CONTENTS. The mark “<R>” shows major

revised points. The revised points can be easily searched by copying an “<R>” in the

PDF file and specifying it in the “Find what:” field.

• How to interpret the register format:

→ For a bit number enclosed in angle brackets, the bit name is defined as a reserved

word in the RA78K0, and is defined as an sfr variable using the #pragma sfr directive

in the CC78K0.

• To check the details of a register when you know the register name:

→ See APPENDIX C REGISTER INDEX.
