TMF0064中文资料具有 64 位唯一标识和 SDQ™ 单线串行接口的 64K 位 FRAM 存储器数据手册TI规格书

描述 Description

The TMF0064 is a 64Kbit serial non-volatile memory (NVM) device containing a unique factory-programmed 48-bit identification number and an 8-bit family code. The memory is FRAM-based and has high endurance (106 R/W cycles) in comparison to alternate NVM technologies.

The device communicates over a SDQ™ single-wire interface and supports both 15.4kbps and 90kbps speeds. The SDQ pin acts as both the communication and power pin for the device. The memory is organized as 253 memory pages with 256 bits per page. Data is first written to a 32-byte scratchpad. The data is verified before copying to FRAM memory.

The device operates at two supply voltage ranges, 3.3V ±5% and 5V ±5%, and is specified from -10°C to 85°C. The operating range covers most applications and enables peak design for low-cost development.
