I really like this chip. Its got 1024 bytes of on-chip XDATA RAM and 16KB or on-chip CODE EPROM. However, I'm running out of room. Does anyone know of another chip that has the 1024 bytes of XDATA but has more than 16KB of EPROM??

Dan Henry Probably not as fast as the Dallas part, but Philips has a few that might fit the bill with 1K RAM. To start, the '558 has 32K ROM and the 'C51RD+ has 64K flash. http://www.semiconductors.philips.com --Dan Henry

These have 32K and 64K flash, and 512 and 1024 bytes of ram respectively. They are also reduced cycle chips i.e. they use 6 clock cycles per machine cycle rather than 12 clocks. They will not be as fast as the Dallas 520, even then though.
