• 5V DC powe supply.

5.5 LOW VOLTAGE DETECTION

• A 20K Pot P1 along with ladde netwo k esisto s is used to gene ate equi ed

voltages fo Exte nal Low Voltage Detection.

6.0 SKP FUNCTIONAL BLOCKS

The SKP is composed of a H8/36912F single-chip mic o-cont olle , Low Voltage D op

Out Regulato , 2KBit EEPROM, Se ial po t, 20K POT fo LVD & ADC, Dipswitches fo

Oscillato b eak & Boot/Use mode t ansition, use inte face LEDs and E7 Heade to

connect with E7 Emulato .

JP1 jumpe is used fo cu ent measu ement of the micon. This jumpe is always closed

and opened du ing cu ent measu ement.

The DIP Switch SW1 is used to select the p og amming mode fo the micon i.e., Boot

mode o Use mode fo p og amming the FLASH. A eset switch SW3 is also p ovided

with a eset led indication. SCI3 is used to p og am the boa d’s on-chip flash memo y

using FDT o it is used fo Se ial t ansmission o eception.

The DIP Switch SW2 is used to select led indication on OSCBK/PWM1 and

LVD/PWM2 LEDs.

The DIP Switch SW4 is used to connect o disconnect led indication on TxD and RxD

LEDs du ing se ial communication.

Low Voltage Detection is detected using Pot P1 and esisto ladde netwo k. A 2Kbit

EEPROM is used to sto e data du ing low voltage detection and ecove data sto ed when

micon ope ates at no mal voltage.

A/D conve sion is also ca ied using the same POT P1. Analog signal is supplied to the

mic ocont olle by va ying POT and digital output is checked on inte nal egiste s.

7.0 PRINCIPLES OF OPERATION

The SKP is composed of the following components:

• H8/36912F mic o cont olle

• Exte nal Low Voltage Detection ci cuit y

• Clock ci cuit y

• RESET ci cuit y

• NMI ci cuit y

• I2C Inte face

7.9 LEDS and DIP Switches

The e a e fou LED’s on the SKP that a e available to the use . Led OSCBK /

PWM1 can be d iven using Po t 84 of the H8/36912F and SW2 pin 1.

Powe = Powe of Ta get boa d indication.

OSCBK/PWM1 LED = Oscillato B eak o PWM of Time W indication.

LVD/PWM2 LED = Low voltage Detection o PWM of Time W indication.

TxD LED = T ansmit data indication of SCI3.

RxD LED = Receive data indication of SCI3.

BOOT LED= Boot mode indication.

Reset LED = Reset level indication.

Exte nal oscillato b eak indication: -

Keep SW2.1 in OFF condition and w ite high on P84 to tu n ON OSCBK/PWM1. This

led can be used to indicate exte nal clock fail o lit acco ding to PWM pulse width on

po t 8.

Downloaded from Elcodis.com electronic components distributor

To disconnect OSCBK/PWM1 led indication, tu n ON SW2.2 pin 1(i.e., connect SW2.1

pin to GND).

Low Voltage Detection: -

Tu n ON SW2.2 to use LVD/PWM2 led. This led can be used to indicate low voltage

detection o lit acco ding to PWM pulse width on po t 8.

To disconnect LVD/PWM2 led indication, tu n ON SW2.1 pin 1(i.e., connect SW2.1 pin

to GND).

SCI3: -

Two led’s TxD and RxD a e used to indicate t ansmit and eceive ope ations of SCI3

du ing se ial communication. P ovision to connect/disconnect led indication fo these I/O

lines is p ovided using a DIP Switch SW4.

Tu n ON SW4.1 to use RxD led indication. Tu n ON SW4.2 to use TxD led indication.
