1. Introduction
EVBST7-DISK is a development board designed for the hobbyists and
engineers who want easily prototype their system based on ST7LITE and ST72F26x
microcontrollers from STMicroelectronics. This board allows implementing engineer’s
idea without a hitch.
Developer has access to all pins all processors and peripherals devices, which are
connected to the header (pin connectors). There are six sockets for microcontrollers
(which every microcontroller is independent)
and peripheral devices like:
thermometer, relays, potentiometers, eight buttons and eight LED’s, real time clock,
interface RS232, FLASH memory, LED displays and optionally assembled LCD (2 x
16 symbols) on board.
The board contains also a power supply which relieves the user from the need to
provide a regulated supply voltage. This board comes with the several examples of
the C code routines (source form), to facilitate testing and quick development in using
the board’s resources.
We wish great success and full satisfaction while designing and
constructing appliances based on EVBST7-DISK
Features:
- 6 sockets for microcontrollers
- connectors of all peripherals accessible on board
- power supply circuit
- port RS232
- independent programming connectors
- socket for LCD 2x16
- 2 potentiometers
- 8 buttons
- real time clock
- Flash memory
- 8 LEDs
- 4 LED displays
- buzzer

- ST7226x (SDIP-32)
- ST7LITE3 (DIP-20)
- ST7LITE2 (DIP-20)
- ST7LITE1xB (DIP-16)
- ST7LITE0 (DIP-16)
- ST7SuperLite (DIP-16)
- ST7UltraLite (DIP-8)
4. Board power supply
Recommended external power supply voltage is 7-12V AC, or 9-15V DC. A
standard power jack (bolt diameter 2.1mm) is provided at the edge of the board.
Stabilized voltage VDD is available on the double header and on the prototype area
of the board. The selection of the VDD is provided through a 3V3 header. The default
voltage VDD is 5VDC (no jumper on 3V3 header). By placing a jumper Vdd becomes
3.3 VDC.
4
The SUPPLY jumper provides power from voltage regulator to devices and
microcontrollers. Additionally, each microcontroller has one jumper to provide power
supply voltage to microcontroller VDD pin. The jumpers’ names are: PWR ST72,
PWR L3, PWR L2, PWR L1xB, PWR L0/S and PWR UL. These additional jumpers
where implement to give a possibility of current measure or powering MCU from
battery.
5. Microcontrollers circuits
There are six sockets on board for microcontrollers marked on Fig.1 as 1, 2…
6, six programming connector for each MCU and four of them have quartz oscillator.
Every MCU is connected to own header. This construction allows working with more
than one MCU at the same time.
6. Peripheral circuits
6.1. LED’s
The board has 8 LED diodes, which make the simplest interface between the system
and the user. This is especially useful for the beginners. All diode are connected via
resistor to VDD, the diode turns on after grounding of the associated LDn (n = 0 –
8)pin

User has to connect 5 and 6 pin on JP2 to power the RTC from board VDD, or
connect by wire VRTC pin with one pin on JP26 to power it from battery. Data Sheet
of M41T81 user can find on www.st.com/rtc web site.
On all pins of BAT header are connected though diode D11 to battery, from
where can power for example MCU or Flash. The battery can be charging with direct
8
current through LOAD jumper. QL jumper is implementing to quick charging. User
has to be careful to prevent from battery damage in this case. Data Sheet of
GP60BVH battery user can find on www.gpbatteries.com web site.
CAUTION: User shouldn’t charge/discharge the battery with more than specified
current at Data Sheet!!!
6.9. LCD
The LCD (2 x 16 characters) socket is connected to JP6 header. The
connection method permits only the write operation to the display, which is, however,
sufficient for its operation. Contrast adjustment can be regulated by R12
potentiometer, when user will connect pins 1 and 2 on JP6.

Fig.10.Schematic of LCD connection
Four data lines (D4-D7) and two control lines (R/S, E) are available on JP6
header. Pin no. 9 is used to control LCD backlight through transistor. This pin can be
permanently connected to pin no.10.
6.10. FLASH memory
The M45PE80 is a 8Mbit (1M x 8 bit) Serial Paged Flash Memory accessed by
a high speed SPI-compatible bus (up to 33MHz). One page of memory is storing
256B.
Memory supply voltage range is between 2.7V and 3.6V. Because voltage of
board power supply may be to 5V, memory is powering passing by LED diode.
However the inputs of memory are connected by resistors.
When voltage of board power supply is regulated to 3.3V, user can close
FLASH PWR jumper to power memory directly (without diode).

8. Jumpers
3V3 – when closed causes 3.3V at board power supply, otherwise the power supply
is 5V
SUPPLY – when closed regulated voltage is provided from local power supply circuit
FLASH PWR– closed when voltage of power supply is 3.3V, when 5V this jumper
should be open
PWR ST72, PWR L3, PWR L3, PWR L1xB, PWR L0/S, PWR UL – these jumpers
when closed are providing board power supply to
microcontrollers
ICP PWR – this jumper is used to provide power supply for ICPcable I programmer
when user wants to program ST7UltraLite microcontroller when
power supply is off
OSC1 and OSC2 – these jumpers are used to closing X2 quartz pins to ground when
internal oscillator for ST7226x is used; in case when external
clock source is connected to pin OSC1, only OSC2 jumper
should be closed; when using X2 quartz both jumpers should be
open
OSC3, OSC4 and CLKIN2 – jumpers OSC3 and OSC4 are using to closing X3
quartz pins to ground when internal oscillator for ST7LITE1xB is
used;
In case when external clock source is used (connected to OSC1
or PB4 pin) the jumper OSC3 should be closed;
When external clock source will be delivered through
programming connector, user has to close CLKIN2 jumper
(external clock will be connected to PB4/CLKIN pin) or close pins
between CLKIN2 and OSC4 (external clock will be connected to
OSC1/CLKIN pin) as on picture below

When ICP OPT Disable mode is used to programming MCU,
clock source from programmer has to be connected to PB4
through CLKIN2
OSC7, OSC8 and CLKIN4 – jumpers OSC7 and OSC8 are using to closing X5
quartz pins to ground when internal oscillator for ST7LITE3 is
used;
In case when external clock source is used (connected to OSC1
or PB4 pin) the jumper OSC7 should be closed;
When external clock source will be delivered through
programming connector, user has to close CLKIN4 jumper
(external clock will be connected to PB4/CLKIN pin) or close pins
15
between CLKIN4 and OSC8 (external clock will be connected to
OSC1/CLKIN pin) as on picture below

quartz pins to ground when internal oscillator for ST7LITE2 is
used;
In case when external clock source is used (connected to OSC1
or PB4 pin) the jumper OSC5 should be closed;
When external clock source will be delivered through
programming connector, user has to close CLKIN3 jumper
(external clock will be connected to PB4/CLKIN pin) or close pins
between CLKIN3 and OSC6 (external clock will be connected to
OSC1/CLKIN pin) as on picture below

When ICP OPT Disable mode is used to programming MCU,
clock source from programmer has to be connected to PB4
through CLKIN4.
CLKIN5 – when this jumper is closed external clock source is connected from
ICP_UL programming connector to PA5/CLKIN ST7UltraLite pin.
CLKIN1 - when this jumper is closed external clock source is connected from ICP_L0
programming connector to PA5/CLKIN pin of ST7Lite0 or
ST7SuperLite
POWER diode – when this diode is shining, the power is connected to VDD.
