#89588 - XRAM and mnufacturers Responding to: ???'s previous message |
Philips' P89C51RD2 and P89V51RD2, as well as the equivalents from SST and Winbond, all have 768 bytes XRAM. Temic's (now Atmel's) T89C51RD2 (which has been already obsoleted) has 1024 bytes XRAM (+2kB EEPROM) Atmel's AT89C51RD2/ED2 has 1792 bytes of XRAM (ED2 has the extra EEPROM; RD2 is not available in DIP).

| XRAM, more | 01/01/70 00:00 | |
| SW-I2C mostly sufficient ! | 01/01/70 00:00 | |
| similar CPU load?? pray explain | 01/01/70 00:00 | |
| "...significant advantage..." | 01/01/70 00:00 | |
| how do you do soft IIC with 1% load | 01/01/70 00:00 | |
| 1% = | 01/01/70 00:00 | |
| Peters 1% | 01/01/70 00:00 | |
| very high data rates?? | 01/01/70 00:00 | |
| consider the whole program ! | 01/01/70 00:00 | |
| Its really very high. | 01/01/70 00:00 | |
