8 Bit up With Lots Of RAM

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 (

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

one of the AVRs that

Mike,

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.

maybe use one of the AVRs that

Mega128/64/161/162/103/8515, S8515/4414, CAN128

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.

Take a look at the Renesas M16C familly - ok, 31KB of ram, but lots of flash (up to 512KB) easy to use and cheap.
