This is what the top of the micro-controller looks like:
P8052AH 1068 L5372984 0348013 INTELΘ®1980 The 8052 doesn't have on-board EPROM (that would be the 8752). It also doesn't have mask ROM, which would be the 8032 (if they actually made an 8032 available to large OEM customers who could afford the mask charges). If you go back and look in the 1980 Intel data book, you'll see that the "romless" version is the 8032, and the 8052 is the masked-rom version. The OTP initially was sold as 865x, but later was simply labeled 8052 with appropriate suffix indicating lot number, mask number, etc. The 8052 requires an external memory for code storage, so you need to get an EPROM or some such. Well, that actually applies to both the masked-rom parts and the 8032, as either one, with nEA grounded, uses external memory. Leave the 8052 on top of your monitor as a curio and just go with the Silicon Labs devices.
-a [edit] I agree that the SiLabs offering is the most promising for his eventual goal, particularly later on, and specifically the 'F120 EVK. It has the potential for the most expansion of any of their devices, particularly since there's that site for a DIN41612 expansion connector. I can't think of a better alternative.[/edit] RE |
