#394 AT89C2051/Programmer Building a programmer for the Intel MCS-51/8051 compatible AT89C2051, with host software running on MacOSX. Notes I've been meaning to dive a bit deeper into devices and programming ever since I built the LEAP#088 ElectronicClockKit. While it's long been EOL at Intel, is a valiant argument for why they are still around. I have some (still in production) chips - but before I can do much more, I need a programmer. Reading the AT89C2051 datasheet, its seems programming is actually a quite straight-forward process - the only complication being the need for a 12V programming voltage in addition to standard logic high of ~5V.

So while I could go out and buy a programmer, the idea of building my own is very attractive for two reasons: • it is a bit of a short cut to building familiarity with the chip and datasheet • I can make sure it supports my host platform of choice - MacOSX Inspirations and Prior Art I found a couple of interesting projects that provided a good starting point. I'd recommend checking these out.

Schematic Atmel 89C2051 In-Circuit Programmer Schematic This is a 'beta release' schematic. Use at your own risk The idea is to add this circuitry to a board with already has ram at 2000 and an 82C55 I/O chip to provide ports A, B and C. Warning: not shown here is a memory mapping trick which is described below. You must figure out a way to provide the necessary memory mapping to make beta version 0.003 work.

The next beta release will fix this problem, so that an ordinary memory configuration will work. But for now a hardware trick or some preprocessing of your intel hex files is needed.

The AND and NAND gates shown should be 74HC08 and 74HC00 respectively. It a TTL type NAND gate is used (eg LS, L, S, ALS, etc) the crystal oscillator may be problematic. Several people have asked. Here's a few things to try.

NOTE: in the above schematic, the line indicated P3.3 (which controls the TXD echo feature) should really connect to P3.4, and the one labeled P3.4 really ought to connect to P3.3. I'll get a fixed copy of this schematic on-line sometime, with the signals names that now appear in. On the bright side, if you do connect it differently, it's a simple matter to reassign the pins in the software with 0.004. The inputs on the left side of the schematic come from the ports on the 8051 and 82C55.
