1.3 - Board Introduction
Pantech Solutions’ Embedded Advanced Development module is proposed
to smooth the progress of developing and debugging of various designs
encompassing 8051 Microcontrollers from Philips / Atmel/ Dallas. The
intention of the design is to endorse the engineers to exercise and explore
the capabilities of 8051 microcontrollers with many communication
protocol ease.
The board is compatible with 40-DIP/44-PLCC pin
Microcontrollers. The kit is designed so as to facilitate separate On-board
ISP Programmer for Atmel microcontrollers and Philips Microcontroller
through ISP on serial port. Programming can be done without detaching the
Microcontroller from the ZIF socket.
It provides a complete development platform with different modules
interface that accelerates the task of designers to run application software
on target 8051 hardware, thereby paving a platform to benchmark their
system, save time & expense of building their own application test board
and enabling them to get their designs to market quickly. Many real world
applications can be tested on the board. RS485, RTC, DAC, Digital
Temperature controllers, Motor drivers, Memory interfacing, counters,
timers...

6.5 - RS-232 Communication
RS-232 communication enables point-to-point data transfer. It is commonly
used in data acquisition applications, for the transfer of data between the
microcontroller and a PC.
The voltage levels of a microcontroller and PC are not directly compatible
with those of RS-232, a level transition buffer such as MAX232 be used.

6.6 - Real Time Clock
The DS1307 Serial Real-Time Clock is a low power; full binary-coded decimal
(BCD) clock/calendar plus 56 bytes of NV SRAM. The DS1307 has a built-in
power sense circuit that detects power failures and automatically switches
to the battery supply. In Embedded module’s DS1307 of pin SDA and SCL
connected to the Microcontroller’s pin P2.6 and P2.7 respectively. Address
and data are transferred serially via a 2-wire, bi-directional bus. The
clock/calendar provides seconds, minutes, hours, day, date, month, and
year information. The end of the month/ date is automatically adjusted for
months with fewer than 31 days, including corrections for leap year. The
clock operates in either the 24-hour or 12-hour format with AM/PM
indicator.
This RTC circuit is facilitated with Battery backup, when supply fails; battery
voltage goes to DS1307 RTC chip.

6.8 - Seven Segment Display
In Embedded module 4 nos. of common anode seven segment displays are
used. The segment lines of seven segments LED is being terminated at
connector CN9. The digit select lines are connected to the port pins of 8051
by using BC547. All the common anode displays consume very small amount
of current. User can use segment lines at any port P0, P1 and P2, by default
digit select lines connected to Port P3 of Pin3.4 to P3.7.

6.12 - Motor / Driver Section
The ULN2803A is a high-voltage, high-current Darlington transistor array.
The device consists of eight NPN Darlington pairs that feature high-voltage
outputs with common-cathode clamp diodes for switching inductive loads.
The collector-current rating of each Darlington pair is 500mA. The
Darlington pairs may be connected in parallel for higher current capability.
ULN2803 is used as a driver for port I/O lines, drivers output terminated to
connector CN12, there can interface relay/stepper motor or any driving
source could need more than 50mA. Motor can connect JP3 or J3
connector.
Note : User select Internal VCC or External through JP6 header.

The Microchip Technology Inc. MCP3202 is a successive approximation 12bit Analog-to-Digital (A/D) Converter with on-board sample and hold
circuitry. The MCP3202 is programmable to provide a single pseudodifferential input pair or dual single-ended inputs. Differential Nonlinearity
(DNL) is specified at ±1 LSB, and Integral Nonlinearity (INL) is offered in ±1
LSB (MCP3202-B) and ±2 LSB (MCP3202-C) versions. Communication with
the device is done using a simple serial interface compatible with the SPI
protocol. The device is capable of conversion rates of up to 100ksps at 5V
and 50ksps at 2.7V.

6.18 – RF433.92MHz
Radio Frequency, any frequency within the electromagnetic spectrum
associated with radio wave propagation. When an RF current is supplied to
an antenna, an electromagnetic field is created that then is able to
propagate through space. Many wireless technologies are based on RF field
propagation.
