I am new member of this forum.
i need help on microchip 23K256(Serial SRAM,SPI). i need to interface it with the 89c52 atmel microcontroller. as 23K256 works on 3.6V i need to translet TTL 5V logic to 3.6V logic using transistor logic. i am using bit-bang method for communication. has anyone worked on 23K256 ? if so please (...)

Thanks again to all who reply.
You will find a attached file for the schematic which I designed.
The circuit is designed to read 8 PT100 sensors on PC using parallel port.
I need to use a micro controller instead and controlling 8 heaters concerning to the temperature sensors.
Can you help me find the suitable micro controller supporti

please provide me a simple schematics of Philips 89c52 programmer. better if it is serial programmer (DB9) ( I think this is equal to atmel 89c52 )
your reply is much appreciated.

I had built and worked similar project using atmel 89c52 and RFID bought from united77.com. The relay on board can be connected to any electromagnet to lock the door. But this kit doesnt communicate to any PC. They provide all details including schematics, PCB's and components with project description. Hope this will help you. The said kit is also

I am facing a problem interfacing the Cirrus CS5450A to atmel 89C51/ 89c52 microcontroller.
I want to know how to read data from the 5460A. The SCK, SDO, SDI pins are being read through T0, T1 and WR pins (Port 3 pins 4,5,6). I went through the datasheet of 5460 and tried some code, but the bytes read are some arbitrary value

There is no AT90s52. you probably mean the AT89c52 which is the 8052 family (basically the same as the 8051). you can find a lot of info on or atmel website (datasheets)

how i connect the stepper motor with 89c52 (directly or with interfacing with ic)
what type of stepper are you using? you cannot connect a stepper directly to the micro since output current from ports is to small. you nee a driver. such as l297 etc
