23A640-I/ST Frequently Asked Questions (FAQ)
-
The maximum clock frequency for the 23A640-I/ST is 20 MHz.
-
To implement a reliable reset mechanism, connect the RESET pin to a 10 kΩ pull-up resistor and a 0.1 μF capacitor to VCC. This ensures a clean reset signal and prevents unwanted resets.
-
The recommended power-up sequence is to apply VCC first, followed by the clock signal (SCK). This ensures proper initialization and prevents latch-up conditions.
-
To handle bus contention, use a separate chip select (CS) line for each device and ensure that only one device is selected at a time. You can also use a bus arbiter or a multiplexer to manage multiple devices on the same bus.
-
The maximum number of devices that can be connected to the same SPI bus depends on the specific application and bus loading. As a general rule, it's recommended to limit the number of devices to 4-6 to maintain reliable communication.
