DS1345YL-70规格书详情
DESCRIPTION
The DS1345 1024K Nonvolatile SRAMs are 1,048,576–bit, fully static, nonvolatile SRAMs organized as 131,072 words by eight 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. Additionally, the DS1345 devices have dedicated circuitry for monitoring the status of VCC and the status of the internal lithium battery.
FEATURES
• Built–in lithium battery provides more than 10 years of data retention
• Data is automatically protected during VCC power loss
• Power supply monitor resets processor when VCC power loss occurs and holds processor in reset during VCC ramp–up
• Battery monitor checks remaining capacity daily
• Read and write access times as fast as 70 ns
• Unlimited write cycle endurance
• Typical standby current 50 µA
• Upgrade for 128K x 8 SRAM, EEPROM or Flash devices
• Lithium battery is electrically disconnected to retain freshness until power is applied for the first time
• Full ±10 VCC operating range (DS1345YL) or optional ±5 VCC operating range (DS1345BL)
• Low Profile Module package fits into standard 68–pin surface mountable PLCC sockets
• Optional industrial temperature range of –40°C to +85°C, designated IND
