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

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.

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.

The Philips LPC2105 has 128KB flash and 32KB RAM.

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.


Re: 8 Bit up With Lots Of RAM
Take a look at the Renesas M16C familly - ok, 31KB of ram, but lots of
flash (up to 512KB) easy to use and cheap.
