Description

The DS1265 8M Nonvolatile SRAMs are 8,388,608-bit, fully static nonvolatile SRAMs organized as 1,048,576 words by 8 bits. Each NV SRAM has a self-contained lithium energy source and control circuitry which constantly monitors VCC for an out-of-tolerance condition. When such a condition occurs the lithium energy source is automatically switched on and write protection is unconditionally enabled to prevent data corruption. There is no limit on the number of write cycles which can be executed and no additional support circuitry is required for microprocessor interfacing.

This product contains lithium-metal batteries. See applicable regulations for transport requirements for batteries in equipment.

Key Features

10 years minimum data retention in the absence of external power Data is automatically protected during power loss Unlimited write cycles Low-power CMOS operation Read and write access times as fast as 70ns Lithium energy source is electrically disconnected to retain freshness until power is applied for the first time Full ±10% VCC operating range (DS1265Y) Optional ±5% VCC operating range (DS1265AB) Optional industrial temperature range of -40°C to +85°C, designated IND Underwriters Laboratories (UL®) Recognized
