Pin Definitions
Pin Name[1, 2, 3] I/O Type
Description
CS
Input
Chip Select. Activates the device when pulled LOW. Driving this pin high puts the device in low
power standby mode.
SCK
Input
Serial Clock. Runs at speeds up to a maximum of fSCK. Serial input is latched at the rising edge of
this clock. Serial output is driven at the falling edge of the clock.
SI
Input
Serial Input. Pin for input of all SPI instructions and data.
SO
Output Serial Output. Pin for output of data through SPI.
WP
Input
Write Protect. Implements hardware write protection in SPI.
HOLD
Input
HOLD Pin. Suspends Serial Operation.
HSB
Input/Output
Hardware STORE Busy:
Output: Indicates busy status of nvSRAM when LOW. After each Hardware and Software STORE
operation HSB is driven HIGH for a short time (tHHHD) with standard output high current and then
a weak internal pull up resistor keeps this pin HIGH (External pull up resistor connection optional).
Input: Hardware STORE implemented by pulling this pin LOW externally.
VCAP
Power supply 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 ground.
NC
No connect No Connect: This pin is not connected to the die.
VSS
Power supply Ground
VCC
Power supply Power supply
Notes
1. HSB pin is not available in 8-pin SOIC packages.
2. CY14X101Q1A part does not have VCAP pin and does not support AutoStore.
3. CY14X101Q2A part does not have WP pin
