Description
The U630H64 has two separate modes of operation: SRAM mode and nonvolatile mode, determined by the state of the NE pin.
In SRAM mode, the memory operates as an ordinary static RAM. In nonvolatile operation, data is transferred in parallel from SRAM to EEPROM or from EEPROM to SRAM. In this mode SRAM functions are disabled.

Features
❐ High-performance CMOS nonvolatile static RAM 8192 x 8 bits
❐ 25, 35 and 45 ns Access Times
❐ 12, 20 and 25 ns Output Enable Access Times
❐ Hardware STORE Initiation (STORE Cycle Time < 10 ms)
❐ Automatic STORE Timing
❐ 105 STORE cycles to EEPROM
❐ 10 years data retention in EEPROM
❐ Automatic RECALL on Power Up
❐ Hardware RECALL Initiation (RECALL Cycle Time < 20 µs)
❐ Unlimited RECALL cycles from EEPROM
❐ Unlimited Read and Write to SRAM
❐ Single 5 V ± 10 % Operation
❐ Operating temperature ranges: 0 to 70 °C -40 to 85 °C
❐ CECC 90000 Quality Standard
❐ ESD characterization according MIL STD 883C M3015.7-HBM (classification see IC Code Numbers)
❐ Packages: PDIP28 (300 mil) SOP28 (330 mil)
