Chapter 2.Purpose

This RSK Application Board is an evaluation tool for Renesas microcontrollers with an LCD driver interface. It is used in conjunction with

the RSK for the microcontroller to be evaluated.

Features include:

•Mounting connections to allow RSK to be added to top of board.

•Interface to standard RSK LCD expansion connector and RSK expansion connections.

•8 character 14 segment “starburst” LCD.

•Coin cell holder to power mounted RSK for low power operation.

Chapter 4.User Circuitry

4.1.Fitting the Target RSK to the RSK LCD application board

The board is supplied with 2x 24 way sockets, 2x 26 way sockets and 1 x 50 way socket.

These should be soldered on the underside of the host RSK in JA1, JA2, JA5, JA6 and JA4 positions.

The RSK should be plugged into the equivalent connectors on the RSK LCD application board.

4.2.LCD Module

The LCD module on the board is connected to the RSK LCD connector JA4.

It uses ¼ duty cycle and has 4 common lines. There are 8x14 segment starburst characters. Refer to Figure 4-1: LCD Segment Names.

Each character uses 4 SEG lines. Each SEG line controls 4 segments on the LCD as it uses ¼ duty cycle.

The LCD controller must be programmed for ¼ duty cycle.

In the case of the H838347, a RAM in the LCD controller has 1 bit per segment. Thus each character is a 16 bit number.

The following Table 4-1: LCD character maps gives the bit mappings for common characters for this controller.

The lowest address (H’F740 in the case of the H838347) represents the rightmost character of the display.

The next word address (H’F742 in the case of the H838347) represents the next character, etc.

4.3.Coin Cell and switch.

The board includes a coin cell holder to hold a 2032 3.6V coin cell. To power the attached RSK from this cell the switch must be in the

“ON” position.

IT IS IMPORTANT NOT TO POWER THE ATTACHED RSK VIA THE POWER SUPPLY JACK OR VIA THE

E8A IF THIS OPTION IS USED.

Caution: If processor is not in low power mode at start up the battery life will be significantly reduced.

4.4.Capacitors

Pads are supplied to allow 0603 capacitors to be placed on the LCD drive voltages V1 – V4.
