#125246 - 8051 microcontroller with ISO7816 & I2C |
Hi,
I'm involved in a project that requires a low cost microcontroller interfacing with a smart card via ISO7816(t=0) and another IC via 2 wire serial interface(i2c). I'm wondering if there are any 8051 microcontrollers that have both these interfaces? I checked out Atmel's AT89C51/AT89SC2051/AT90SC series but they only have 7816 but not i2c. |

| Maybe not a good idea | 01/01/70 00:00 | |

| WHY? | 01/01/70 00:00 | |
| I use bit-bang instead of hardware i2c | 01/01/70 00:00 | |
| as often as with an UART | 01/01/70 00:00 | |
| for those wondering | 01/01/70 00:00 | |
