SINGLE-CHIP 16-BIT CMOS MICROCOMPUTER

REJ03B0014-0501

Rev.5.01

Dec 10, 2009

Overview

The M16C/6S group are highly integrated single-chip microcomputers with PLC (Power Line Communica-

tion) modem core and AFE (Analog Front End) in a 64-pin plastic molded LQFP package, which incorpo-

rates IT800 PLC modem technology developed by Yitran Communications Ltd. M16C/60 Series CPU core

enables a high level of code efficiency and high-speed operation. In addition, the implementation of Yitran's

patented DCSK (Differential Code Shift Keying) spread spectrum modulation technique in the IT800 mo-

dem core enables extremely robust communication over the existing electrical wiring, with data rates up to

7.5Kbps. The M16C/6S complies with worldwide regulations (FCC part 15, ARIB and CENELEC bands)

and is suitable for a variety of narrowband applications like smart metering and home networking.

M16C/6S Group

Overview

IT800 PHY performance outline of M16C/6S group.

The IT800 PHY is a PLC optimized Physical Layer (PHY) which consists of IT800 modem core and internal

AFE (Analog Front End). The implementation of Yitran's patented DCSK spread spectrum modulation

technique in the IT800 modem core enables extremely robust communication over the existing electrical

wiring, with data rates up to 7.5Kbps. In addition to the inherent interference immunity provided by the

DCSK modulation, the IT800 PHY utilizes several mechanisms for enhanced communication robustness,

such as forward short block soft decoding error correction algorithm and special synchronization algo-

rithms.

The IT800PHY communicates M16C core with clock synchronous serial I/O, interrupt and input/output

ports in M16C/6S (Note). M16C/6S requires external AFE. Table 1.1.2 lists IT800 PHY performance outline

of M16C/6S group.

Note:

Direct operation of IT800 PHY is not recommended. Since the Layer 2 (DLL) handles the channel access

procedure, using the IT800DLL as such assures coexistence with other IT800 technology based products,

regardless of the vendor, protocol and the application. There is NO such coexistence if the device is used

in direct operation of IT800 PHY. Note that the coexistence here is not with other technologies but with

other IT800 technology based products. As for details, please refer to the next section and Appendix.

About Firmware

Renesas recommends IT800DLL (Product name: D2DL) as a Data Link Layer (DLL) of M16C/6S group.

The IT800 DLL is a PLC optimized DLL especially for the products based on Yitran's IT800 technology. For

availability of IT800DLL, please contact Renesas technical support representative. For more details about

the IT800DLL advantages, please refer to Appendix.
