That memory usage is quite large for an 8051 - have you considered a complete architecture change? Low-end ARMs (Cortex-Mx) are now very cost-competetive (sometimes even cheaper) than high-end 8051s. Also, looking at the 2 Keil threads above, it seems (unsurprisingly) that things have moved on a very long way since what was available when the '251 was current. Therefore, the learning curve to get current with 8051 might not be that much shallower than the learning curve to switch architecture... |
