23A640T-I/ST Frequently Asked Questions (FAQ)

  • The maximum clock frequency for the 23A640T-I/ST is 20 MHz.

  • A reliable reset circuit can be implemented using a voltage supervisor IC (e.g., MCP809) or a simple RC circuit with a diode to ensure a clean power-on reset.

  • The recommended power-on sequence is to apply VCC first, followed by VPP (if used), and then the clock signal. This ensures proper device initialization and prevents latch-up.

  • To handle bus contention, use a bus arbiter or a bus controller IC (e.g., 74HC245) to manage access to the bus and prevent data corruption.

  • The maximum capacitance allowed on the clock input (CLK) is 100 pF to ensure reliable clock signal propagation.
