The R8C family

With its short instruction cycles at 50ns (20MHz) and the

excellent code density, it is possible to use smaller Flash sizes,

which also helps to save cost. This combination of embedded

features, reduced code and high reliability offers developers a

microcontroller for more performance on 8-bit applications.

With its on-chip Flash memory from 4 to 128Kbyte and packages

from 20 to 100-pins this series has now over 300 devices in

production.

In addition to the wide range of peripheral and safety function,

new high performance features like the Data-Transfer-Control

(DTC) module – no need for CPU interfection - has been

implemented. By the middle of 2010 Renesas will introduce the

R8C/Mx devices to support low power applications with only

150uA/MHz.

Today we have Over 600

Introduction

The R8C family

More performance on 8-bit applications

The R8C microcontroller family is the latest in a line of high-

performance microcontrollers from Renesas. At the beginning

of April 2003, we offered the ﬁrst R8C devices, with the unique

innovation of the combination of a 16-bit core and 8-bit internal

bus to maximise performance and minimise cost. Firstly, we

introduced the R8C/1x devices in 20 & 32-pin packages with

memory sizes from 4 to 16kB Flash. With the 2nd R8C/2x

generation at the end of 2005, we added a high-speed 40MHz

on-chip oscillator, as well as new powerful features like motor

control timers, CAN, DA converter, RTC, and a Vcc power supply

reduced to 2.2V. Many other useful features were also added,

including low power modes down to 0.7µA in STOP mode and

1.8µA in WAIT mode.

Due to the excellent market reputation, well known reliability

and high quality, Renesas has continued to expand their product

line up by introducing the next 3rd generation of R8C/3x, R8C/

Lx (LCD) and R8C/3x ASSP groups. There are rising needs in the

increasingly popular green market, for power consumption for

devices and systems. With the latest R8C/Mx and R8C/Lx-SLP

Super Low Power devices these products complement the

roadmap. The internal architecure of the R8C/Lx has some

additional power switch to reduce current down to 20nA

and lower.

Due to the same core, all generations are SW compatible and

simplify emigrations.
