Q & A
- What is the storage capacity of the CAT25640VI-GT3JN?
The CAT25640VI-GT3JN has a storage capacity of 64 Kb, organized as 8Kx8 bits. - What is the operating voltage range of the CAT25640VI-GT3JN?
The device operates within a supply voltage range of 1.8 V to 5.5 V. - What are the supported SPI modes for the CAT25640VI-GT3JN?
The device supports SPI modes (0,0) and (1,1). - How does the HOLD input function on the CAT25640VI-GT3JN?
The HOLD input allows pausing of serial communication when taken low while SCK is low, and resumes when taken high while SCK is low. - What protection mechanisms are included in the CAT25640VI-GT3JN?
The device includes hardware and software write protection, as well as block write protection. - What is the maximum clock frequency for the CAT25640VI-GT3JN at 5 V?
The maximum clock frequency is 20 MHz at 5 V. - How does the Power-On Reset (POR) circuitry function?
The POR circuitry protects the internal logic against powering up in the wrong state and prevents 'brown-out' failure following a temporary loss of power. - What is the purpose of the WP (Write Protect) pin?
The WP pin allows all write operations when held high and disables write operations when tied low. - How does the device handle invalid op-codes?
Any invalid op-code will be ignored, and the serial output pin (SO) will remain in the high impedance state. - What is the operating temperature range for the CAT25640VI-GT3JN?
The operating temperature range is -40°C to +85°C.
