STK16C88

32K x 8 AutoStorePlus™ nvSRAM

QuantumTrap™ CMOS

Nonvolatile Static RAM

FEATURES

DESCRIPTION

• Transparent Data Save on Power Down

• Internal Capacitor Guarantees AutoStore™

Regardless of Power-Down Slew Rate

• Nonvolatile Storage without Battery Problems

• Directly Replaces 32K x 8 Static RAM, Battery-

Backed RAM or EEPROM

• 25ns, 35ns and 45ns Access Times

• STORE to EEPROM Initiated by Software or

AutoStorePlus™ on Power Down

• No Data Loss from Undershoot

The STK16C88 is a fast SRAM with a nonvolatile

EEPROM element incorporated in each static mem-

ory cell. The SRAM can be read and written an

unlimited number of times, while independent non-

volatile data resides in EEPROM. Data transfers from

the SRAM to the EEPROM (the STORE operation) can

take place automatically on power down. An internal

capacitor guarantees the STORE operation regard-

less of power-down slew rate. Transfers from the

EEPROM to the SRAM (the RECALL operation) take

place automatically on restoration of power. Initia-

tion of STORE and RECALL cycles can also be con-

trolled by entering control sequences on the SRAM

inputs. The STK16C88 is pin-compatible with 32k x

8 SRAMs and battery-backed SRAMs, allowing direct

substitution while enhancing performance. The

STK14C88, which uses an external capacitor, and

the STK15C88, which uses charge stored in system

capacitance, are alternatives for systems needing

AutoStorePlus™ operation.

• RECALL to SRAM Initiated by Software or

Power Restore

• 10mA Typical I_CCat 200ns Cycle Time

• Unlimited READ, WRITE and RECALL Cycles

• 1,000,000 STORE Cycles to EEPROM

• 100-Year Data Retention over Full Industrial

Temperature Range

• Commercial and Industrial Temperatures

• 28-Pin PDIP Package
