The CY7C964-ASC can support clock frequencies up to 66 MHz, but it's recommended to operate at 33 MHz or lower for optimal performance and to minimize power consumption.
To configure the CY7C964-ASC for slave mode operation, you need to tie the MODE pin low and ensure that the SCL and SDA pins are connected to the master device. You also need to configure the slave address using the A0, A1, and A2 pins.
The maximum capacitance that can be connected to the SCL and SDA pins is 400 pF. Exceeding this value may affect the signal integrity and reliability of the I2C interface.
To handle bus contention on the I2C bus, you can use a bus arbiter or a multiplexer to ensure that only one device is driving the bus at a time. You can also use a bus buffer or repeater to improve signal integrity and reduce the risk of bus contention.
The power-on reset (POR) timing for the CY7C964-ASC is typically around 10 ms, but it can vary depending on the power supply ramp-up time and other factors. It's recommended to wait for at least 10 ms after power-on before accessing the device.
