#394 AT89C2051/Programmer. Building a programmer for the Intel MCS-51/8051 compatible AT89C2051, with host software running on MacOSX.
AT89C2051 Microcontroller - 20-pin DIP Description The AT89C2051 is a low-voltage, high-performance CMOS 8-bit microcomputer with 2K bytes of Flash programmable and erasable read only memory (PEROM). The device is manufactured using Atmel’s high-density nonvolatile memory technology and is compatible with the industry-standard MCS-51 instruction set. By combining a versatile 8-bit CPU with Flash on a monolithic chip, the Atmel AT89C2051 is a power-ful microcomputer which provides a highly-flexible and cost-effective solution to many embedded control applications. Features • Compatible with MCS-51 ™ Products • 2K Bytes of Reprogrammable Flash Memory – Endurance: 1,000 Write/Erase Cycles • 2.7V to 6V Operating Range • Fully Static Operation: 0 Hz to 24 MHz • Two-level Program Memory Lock • 128 x 8-bit Internal RAM • 15 Programmable I/O Lines • Two 16-bit Timer/Counters • Six Interrupt Sources • Programmable Serial UART Channel • Direct LED Drive Outputs • On-chip Analog Comparator • Low-power Idle and Power-down Modes.

AT89C2051 Atmel Microcontroller with 15 IO lines and 2KB flash memory, 20 pin DIP package Kanda supply our AVR programmer range, PIC programmer range, Universal programmers, AVR board, CANUSB and all our other products to electronic engineers worldwide. We have happy customers for our AVR, PIC and Universal Programmer and other electronic tools in UK and Ireland, Norway, Denmark, Sweden, Finland and other European countries like Netherlands, Switzerland, Austria, Germany, France, Belgium, Spain and Italy.
Outside of Europe, Kanda is strong in USA, Canada, Brazil and other South American countries. We also supply our products further afield in Russia, Australia, Singapore, South Korea, Japan, New Zealand and India. In fact, wherever you are in the world, you can rely on Kanda.
89C2051/4051 Programmer Easy-Downloader V1.1 for ATMEL 89C2051/4051 Wichit Sirichote, Build your own a personal writer for programming HEX code into Flash based microcontroller AT89C2051(2k) and AT89C4051(4k). Simple hardware and Easy use software in DOS and Window version. Single-side and double side PCB files included. Acrobat files for PCB image. Introduction The first version of the Easy-Downloader was designed in 1997 to be used as a tool for my students on building her/his own microcontrollers circuit in the class ' Designing Microprocessors System'. 
The circuit features low-cost and easy use. The latest version V1.1 was designed to be used with 2051 and the newest 4051 chips.
There is no separated functions like other programmer e.g., blank check, erase, write. Simply type say, c:.>ez hello, the hex file 'hello.hex' will then be programmed to the chip automatically. If the chip is not blank or the code is locked, it will erase first, then write and verify. Hardware Figure 1 depicts a circuit diagram of the Easy-Downloader. As shown, the circuit uses a 89C2051 with writer.hex firmware, 74LS373 8-bit latch, DS275-like, 7805, LM317 and two transistors, 2N2222A and 2N2907A. The programming voltage control circuit is the same as recommended by ATMEL application note.
It can be raised from 0V, 5V and 12V by appropriated signal from P3. The 8-bit latch, 74LS373 provides some signal for selecting the programming modes. A byte to be programmed or read back is sent/received through P1. Incrementing address is done by pulsing a positive pulse to XTAL pin. The circuit may be built using simple point-to-point soldering with a general purpose PCB( fish's egg like PCB) or making PCB shown above, the file is Protel PCB version 2.76. The finished board should be tested without any chips; 1) +5V supply, 2) programming voltage 0V, 5V and 12V by connecting the pin that control (P3.5 and D) 2N2222A and 2N2907 to +5V and/or GND.
