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.

Atmel Flash Micro Programmer My Atmel Flash Micro Programmer Introduction: I have build my own programmer. This device can program the AT89C51 and works with it.
So it can be easily adapted to programming other devices by itself. The Atmel Flash devices are ideal for developing, since they can be reprogrammed easy, often and fast. You need only 1 or 2 devices in low cost plastic case for developing. In contrast you need 10 or more high cost windowed devices if you must develop with EPROM devices (e.g. Phillips 87C751). The AT89C2051 is the smallest 8051 member with full resources (128 Byte RAM, 2 Timer, UART).
Only the Flash size and pin count is reduced (2kByte, 20 pin case: 15 IO pins available). Now I have build a programmer for these 20 pin devices working with the AT89C2051: The programmer and the PC are connected via a serial port (COM1.4). No Interrupt is used since every data byte from the programmer must be receipt by the PC. So this program can also run under WINDOWS without data loss. Devices: Today following devices can be programmed: • AT89C51 / AT89C52 (at 12V only) • AT89C1051 / AT89C2051 / AT89C4051 • AT90S1200 / AT90S2313 (AVR) • AT89S8252 / AT89S53 • AT89C55 • ATtiny22 (new) Features: • Input: Intel HEX (use converter to load binary) • Autodetection (read signature at 5V, can failed if device locked) • Fast parallel programming (with ready polling) • Batch mode programming • Programming lock and fuse bits • Adding new devices via definition file (PC program must not modified) • full Protection against misinsertion or misselection Using: The using is quite simple. The example file 'proflash.bat' can be used for calling automatically after generating hex file to program in batch mode. In this case the target must be placed in the programmer before compiling started.

Regarding the wireless I tried to rebrand another wireless card to show as an airport extreme, only to hit the wall with the whitelist present in the lenovos. For the last couple of weeks I have been running along with it as a 'mobile' workstation and I am very happy with it, so I am looking into solving the final issues I have, and perhaps contribute a little bit to the benefit of all.
