Hardware Description 2.2 Block Diagram Figure 2-2 shows the functional block diagram of the AT89STK-11, with the I/O usage. Figure 2-2. Block Diagram of AT89STK-11 PC Host SPI Full UART TWI P0 16MHz Quartz P1 C51 Expansion P2 Area EA PLCC44 RST ISP P3 INT0 INT1 Leds: PWR User LEDs User Push Buttons ALE External Power Supply Power 3V or 5V 2.3 Power Supply The on-board power supply circuitry allows various power supply configurations. This gives the user the capability to power the devices in the 3V and in the 5V voltage range. 2.3.1 Power Supply The power supply source can come from two different and exclusive sources: Sources (cid:1) either from the JACK PWR connector (cid:1) either from the 2-point sip EXT connector. 2.3.1.1 JACK PWR The Jack power connector implemented on board is a female Jack connector with inter- Connector nal 2.1mm conductor. It requires a male JACK outlet with 2.1mm capability. No specific polarization is mandatory as on-board diode rectifier gives a protection against inadvertent polarization invertion. When using the JACK power supply, the board is powered with a 5V voltage. 2-5 AT89STK-11 Hardware User Guide 7676B–8051–08/07

Hardware Description Figure 2-3. Male JACK Outlet and Wires Note: Do not mount more than one power supply source on AT89STK-11 Board. Note: There is a diode voltage level between the negative output of the power supply and the “GND”. This could introduce some voltage gap during measurement and instrumentation. 2.3.1.2 External EXT The battery power connector implemented on board is a male two point SIP connector. connector It requires an external power cable with a female 2 points connector. When powered though this interface, polarization is mandatory as no protection is given on board. The EXT power supply circuitry support input supply from 2.7V up to 5.5V DC. Figure 2-4. EXT PWR Female Connector / Cable Note: Do not mount more than one power supply source on board. Note: Keep SP1 closed when using the EXT input 2.4 Reset To be compatible with Atmel microcontrollers which have (or not) its on-chip RESET cir- cuitry (c.f.microcontroller datasheet), the board provides a RESET signal witch can come from 2 different sources: 2.4.1 Power-on RESET The on-board RC network acts as power-on RESET. 2.4.2 RESET Push Button By pressing the RESET push button on the board, a warm RESET of the microcontroller is performed.

Hardware Description 2.5 Features This section presents the various features such as leds, buttons, etc... available on the board. 2.5.1 Push-Buttons (cid:1) RESET can be used to apply warm reset to the MCU (cid:1) ISP can be used with RESET to apply hardware conditions resulting in bootloader start (cid:1) INT0 push-button can be used to activate INT0 input (cid:1) INT1 push-button can be used to activate INT1 input 2.5.2 User Push buttons (cid:1) PB0, PB1, PB2 and PB3 are four push-buttons available for user application They are made available on a 6 pins socket and in the expansion area so user can use them according to the application needs. 2.5.3 Indicator LEDs (cid:1) PWR led is driven by input of voltage regulator (cid:1) Rx led is connected to Rx of UART MCU (SP3 jumper can be soldered or not) (cid:1) Tx led is connected to Tx of UART MCU (SP4 jumper can be soldered or not) (cid:1) ALE led is connected to ALE of MCU 2.5.4 User LEDs (cid:1) LED0, LED1, ... LED7 are height leds available for user application They are made available on a 10 pins socket and in the expansion area so user can use them according to its application needs. 2.5.5 Ports Port 0 and Port 2 are made available on two 10 pins sockets to ease user interconnec- tion to the MCU. The are also available on the expansion area. 2.5.6 Clocks An external clock can be connected to the board to control externally XTAL1 input clock of MCU by using the XTAL1 from the expansion area. In the same way, another external clock can be connected to control externally the PCA clock (P1.2/ECI). 2.6 Interfaces 2.6.1 TWI The TWI connector is controlled by hardware TWI I/O of MCU (for Product including this feature). The signals sda and scl are controlled by the TWI ports of MCU. This TWI bus is also connected to the expansion area. External TWI pull-ups are not provided on the AT89STK-11. 2.6.2 SPI The SPI connector is directly connected to SPI I/O of the MCU. 2.6.3 RS-232 The DB9 connector is connected to on-chip UART peripheral through a standard RS232 driver/receiver. Two leds are provided to indicate activity on Rx and Tx lines (They can be disconnected removing solder pad SP3 and SP4). 2.6.4 OCD The On-Chip Debug interface (OCD) is provided on a 6-pin connector. 2-7 AT89STK-11 Hardware User Guide 7676B–8051–08/07

Hardware Description This interface enables the debug of the application through ATMEL OCD dongle for AT89C51RE2/IE2/RD3/IE3 only. 2.6.5 Expansion Area In addition to a 16x29 pad array, two rows of pads are given on the right side of the board to offer all the MCU signals tu user application. Any application expansion can be built on board through this interface. 2.7 Board Settings The C51 Demo Board has the following settings: (cid:1) Jumpers (cid:1) Solder straps (cid:1) Test points 2.7.1 Jumpers The following table provides an overview of the jumpers, the solder straps and their default configuration.

Section 3 ISP Programming The On-Chip memories and configuration bytes can be programmed using the ISP mode of the device and Atmel's FLexible In-system Programmer Software (FLIP) described below. 3.1 Manual ISP Mode See Section“FLIP Software”, page11. 3.1.1 Board Configuration To use ISP mode, no specific configuration is necessary on the board. Only make sure that the EA pin of the product is tied to Vcc (internal code execution only). 3.1.2 Operating Mode To enter in ISP mode, press both the RESET and ISP buttons simultaneously. First release the RESET button and then the ISP button. The device enters in ISP mode. 3.2 Auto ISP Mode It allows the host PC application (Atmel Flip software for example) to control the hard- ware conditions from the serial lines RTS and DTR. Thus with the Auto ISP mode, the user does not need to push the ISP and RESET buttons. 3.2.1 Board Configuration To use Auto ISP mode, put the board in the same configuration as ISP mode and also: (cid:1) Close RTS (J11) jumper (cid:1) Close DTR (J12) jumper AT89STK-11 Hardware User Guide 3-10 7676B–8051–08/07

ISP Programming 3.3 FLIP Software FLIP software runs on Windows® and Linux® Operating Systems. FLIP supports in-sys- tem programming of Flash C51 devices through RS232. The latest version of FLIP software can be downloaded from the Atmel web site, www.atmel.com. 3.4 Batchisp Batchisp is an In-System Programming application which can perform the same opera- Software tions as FLIP but is designed to be launched from the DOS command window. The main purpose of batchisp is to automate ISP operations on several parts. It may also be launched from an IDE like Keil's uVision®2 one : you can compile and link your embedded program, generate the HEX file and download it to the target hardware with- out leaving the Keil's IDE. This makes embedded software development and test faster. Autoisp function is an operation which allows to enter in ISP mode without any hardware handling.This is done thanks to DTR and RTS RS232 signals which can control on the Board the RST and PSEN I/O of MCU. 3-11 AT89STK-11 Hardware User Guide 7676B–8051–08/07
