Section 1 Introduction This document describes the board included in the AT89STK-06 Starter Kit dedicated to the T89C51CC01/CC02 and AT89C51CC03 CAN microcontrollers (for T89C51CC02 optionnal adaptor is required). This board is designed to allow an easy evaluation of the product using demonstration software. The AT89STK-06 Starter Kit can be used with the AT89C51AC3, TR89C51AC2, and T89C5115 Flash Microcontrollers with ADC (for T89C5115 optional adapter is required). 1.
Introduction Figure 1-1.
Section 2 Hardware Description 2.1 Block Diagram Figure 2-1 shows a functional block diagram of the AT89STK-06 board, with the I/O usage. Figure 2-1. Block Diagram of AT89STK-06 board CAN Network FLIP, Host, Batch ISP CAN Reset, ISP, INT0, INT1 t°C UART Applicable MCU Sensor 2.2 Power Supply 2.2.
Hardware Description – No specific polarization mandatory Note: There is a diode voltage level between the negative output of the power supply and the “GND”. This could introduce some gap of voltage during measurement and instrumentation. Figure 2-2 . Male JACK Outlet and Wires + - Caution: Do not mount more than one power supply source on AT89STK-06 board.
Hardware Description 2.4 Serial Interfaces 2.4.1 RS-232C All CAN microcontrollers have one on-chip UART peripheral. Only the asynchronous mode is supported by the AT89STK-06 board. The AT89STK-06 board is supplied with a RS-232 driver/receiver. Only one female DB9 connector assumes the RS-232 connections. A full range of configuration can be set with two Rx lines and two Tx lines. Figure 2-4 .
Hardware Description 2.4.2 CAN The microcontroller is a microcontroller with an on-chip full-CAN controller. The AT89STK-06 board is supplied with an Atmel CAN transceiver (ATA6660). A female DB9 connector assumes the CAN bus connections. Figure 2-7 . CAN DB9 Connections CAN DB9 front view 1 2 3 4 5 6 7 8 9 pin 2 CAN-L pin 7 CAN-H pin 3 pin 6 Gnd Gnd pin 5 CAN-SHLD (Can be set to Gnd) If a network termination is needed, JP3 switch inserts a 120Ω resistor between CAN-H and CAN-L.
Hardware Description 2.5 Board Settings The AT89STK-06 board has two types of settings: Jumpers Solder strap Test points Table 2-1, Table 2-2 and Table 2-3 provide an overview of the available settings and test points. 2.5.1 Jumpers Table 2-1.
Hardware Description 2.5.2 Solder straps Solder straps allow to modify the board configuration for specific usage such as T89C51CC02 compatibility. Table 2-2. Table of Solder Strap Reference PCB Name Comments (guidelines) Default SP1 CC02 & C5115 mode For T89C51CC02 usage, allows to redirect the ISP signal to P1.0, for hardware conditions.
2.5.3 Test Points Test points are used to check the internal power supply for AT89STK-06 Board. Table 2-3.

Section 3 Device Programming 3.1 In-System Programming 3.1.1 Manual ISP Mode 3.1.1.1 Board Configuration The on-chip memories and configuration bytes of the AT89C51CC0x parts can be programmed using the ISP mode of the device. To use ISP mode, the board should be configured as follow: POWER switch (SW1) on “ON” position EA jumper should be open (internal code execution only).
