Product suggestion

[Eric Dilley]

Please suggest a development kit. The requirements are below.
600 byte min of EEPROM
2K min RAM
serial input
programming capability
uP bus available to another board
64K address space
assembly programming

Thank you

If I were you I would get the NMIY-0031, but I am partial to the 8051.

Get two 32Kx8 Zero Power SRAMS. (One for data and one for program)

The zeropower SRAM works like the EEPROM because the data stays even after you power down.

If you Really need 64K you can add a third Zero-Power SRAM.

Another way to do this is to get a Philips P89C51RD+ or P89C51RD2 which has 64K FLASH program memory and 768 bytes of SRAM on the Processor to replace the 8031. Then get just one zero-power SRAM, or wire a I2C serial EEPROM to the breadboard, and communicate with it using two of the Port 1 lines.

The RD2 version works twice as fast as a "normal" 8051 with the same clock speed.
