The Renesas R8C is a 16-bit microcontroller that was developed as a smaller and cheaper version of the Renesas M16C . It retains the M16C's 16-bit CISC architecture and instruction set, but trades size for speed by cutting the internal data bus from 16 bits to 8 bits. It is available in a number of different versions with varying amounts of flash memory and SRAM.
All R8C have an internal ring oscillator and can be used without an external resonator. Common interfaces are UART and some devices have CAN interfaces. Some devices have an internal data flash which is meant as a replacement for a serial EEPROM, although it handles less write cycles as a real serial EEPROM. R8C devices have OCD (On Chip Debugging, see In-circuit emulator). When debugging with the Renesas E8 debugger or E8a debugger, UART 1 cannot be used. The debug interface uses only four wires: Vcc, GND, Reset and Mode.

There are people in this country who work hard every day
Not for fame or fortune do they strive
But the fruits of their labor are worth more than their pay
And it's time a few of them were recognized
Hello Detroit auto workers let me thank you for your time
You work a forty hour week for a livin' just to send it on down the line
Hello Pittsburgh steel mill workers let me thank you for your time
You work a forty hour week for a livin', just to send it on down the line
This is for the one who swings the hammer, driving home the nail
Or the one behind the counter, ringing up the sale
Or the one who fights the fires, the one who brings the mail
For everyone who works behind the scenes
You can see them every morning in the factories and the fields
In the city streets and the quiet country towns
Working together like spokes inside a wheel
They keep this country turning around
Hello Kansas wheat field farmer, let me thank you for your time
You work a forty hour week for a livin', just to send it on down the line
Hello West Virginia coal miner, let me thank you for your time
You work a forty hour week for a livin', just to send it on down the line
This is for the one who drives the big rig, up and down the road
Or the one out in the warehouse, bringing in the load
Or the waitress, the mechanic, the policeman on patrol
For everyone who works behind the scenes
With a spirit you can't replace with no machine
