Description
Chip Select. Activates the device when pulled LOW. Driving this pin high puts the device in low
power standby mode.
Serial Clock. Runs at speeds up to max 40 MHz. All inputs are latched at the rising edge of this
clock. Outputs are driven at the falling edge of the clock.
Serial Input. Pin for input of all SPI instructions and data.
Serial Output. Pin for output of data through SPI.
Write Protect. Implements hardware write protection in SPI.
HOLD Pin. Suspends Serial Operation.
Hardware STORE Busy: A weak internal pull up keeps this pin pulled high. If not used, this pin is
left as No Connect.
Output: Indicates busy status of nvSRAM when LOW.
Input: Hardware STORE implemented by pulling this pin LOW externally.
AutoStore Capacitor. Supplies power to the nvSRAM during power loss to STORE data from the
SRAM to nonvolatile elements. If AutoStore is not needed, this pin must be left as No Connect. It
must never be connected to GND.
No Connect: This pin is not connected to the die.
Ground
Power Supply (2.7 to 3.6V)
Notes
1. HSB pin is not available in 8 DFN packages.
2. CY14B101Q1 part does not have VCAP pin and does not support AutoStore.
3. CY14B101Q2 part does not have WP pin
