CY14B101K
1 Mbit 128K x 8 nvSRAM With Real Time Clock

Endurance to 200K cycles Data retention 20 years at 55°C
• 25 ns, 35 ns, and 45 ns access times
• Single 3V operation with tolerance of +20%,
• Pin compatible with STK17TA8
• Commercial and industrial temperature
• Data integrity of Cypress nvSRAM combined with full featured Real Time Clock RTC Low power, 350 nA RTC current Capacitor or battery backup for RTC
• Watchdog timer
• Clock alarm with programmable interrupts
• Hands off automatic STORE on power down with only a small capacitor
• 48-Pin SSOP package ROHS compliant
s Functional Description n The Cypress CY14B101K combines a 1 Mbit nonvolatile static ig RAM with a full featured real time clock in a monolithic integrated
circuit. The embedded nonvolatile elements incorporate
s QuantumTrap technology producing the world’s most reliable e nonvolatile memory. The SRAM is read and written an infinite D number of times, while independent, nonvolatile data resides in
• STORE to QuantumTrap initiated by software, device pin, or on power down
ew
• RECALL to SRAM initiated by software or on power up N
• Infinite READ, WRITE, and RECALL cycles r
• High reliability
the nonvolatile elements.

The Real Time Clock function provides an accurate clock with leap year tracking and a programmable high accuracy oscillator. The alarm function is programmable for one time alarm or periodic seconds, minutes, hours, or days. There is also a programmable watchdog timer for process control.

Input

Output Input

Description Address Inputs. Used to select one of the 131,072 bytes of the nvSRAM. Bidirectional Data I/O Lines. Used as input or output lines depending on operation No Connects. This pin is not connected to the die Write Enable Input, Active LOW. When the chip is enabled and WE is LOW, data on the I/O pins is written to the specific address location. Chip Enable Input, Active LOW. When LOW, selects the chip. When HIGH, deselects the chip. Output Enable, Active LOW. The active low OE input enables the data output buffers during READ cycles. Deasserting OE high causes the I/O pins to tri-state. Crystal Connection Drives crystal on start up. Crystal Connection for kHz crystal.

VRTCcap

Power Supply Capacitor Supplied Backup RTC Supply Voltage. Left unconnected if VRTCbat is used

VRTCbat

Power Supply Battery Supplied Backup RTC Supply Voltage. Left unconnected if VRTCcap is used

Output Interrupt Output. Program to respond to the clock alarm, the watchdog timer, and the power
monitor. Programmable to either active HIGH push or pull or LOW open drain .

VSS VCC HSB

Ground for the Device. Must be connected to ground of the system.

Power Supply Power Supply Inputs to the Device.

Input Output Hardware Store Busy. When LOW this output indicates a Hardware Store is in progress. When pulled LOW external to the chip it initiates a nonvolatile STORE operation. A weak internal pull up resistor keeps this pin HIGH if not connected connection optional .
