Properties |
|
Device Settings |
|
Device Address |
| I2C device address bits (A2, A1, A0). Default is 0x50 (0b1010000). For 1M devices, use two component instances with addresses ending in 0 and 1. | |
|
|
Device Type |
| Select the FRAM device type | |
|
Memory Size (bytes) |
| Calculated memory size based on device type | |
|
|
Address Bits |
| Number of address bits for selected device | |
|
|
Connections |
|
|
Channel |
| Channel selection | |
|
SDA |
| Pin used for SDA (data signal) | |
|
|
SDA Remap Pin |
|
|
