8 Bit up With Lots Of RAM

Started by David Sidlauskas December 5, 2004
Does anyone know of an 8 bit microprocessor with at least 32K of SRAM and 
32K of Flash? Or any number of bits if it's cheap (<$7 @ 1K).

Many thanks in advance.

You may find it cheaper to hook an external SRAM to an I/O port, or maybe use one of the AVRs that have extarnal bus interface

Mike, Which ARV has an external buss interface ????

Renesas (Hitachi) H8/300 3062 "value series" + 32K SRAM totals about $5.50. It doesn't meet your other spec's though: it has 128K of flash and is a 32-bit CPU. ;) Oh, and the tools are free. -- Grant Edwards grante Yow! Darling, my ELBOW at is FLYING over FRANKFURT, visi.com Germany...

The Philips LPC2105 has 128KB flash and 32KB RAM. http://www.semiconductors.philips.com/pip/LPC2105.html Karl Olsen

The large RAM makes that a thin space, but your choices are - uPSD from ST, some with 32K XRAM blocks. - ARM uC from Philips, Atmel have models with 64K - New DS80C401 from Dallas(maxim) has 64K RAM Ramtron have also just released FM25L256, which behaves just like 32K serial SRAM, up to 25MHz SPI.

Can code be run from external memory ???

No, but it has 128KB of program memory. It's also self programmable.

Thank you for the information.
