Memory IC datasheet and documents for MB85RS512LYPNF-G-BCE1
Memory IC Overview
The MB85RS512LYPNF-G-BCE1 is a 512Kbit (64K x 8) Ferroelectric Random Access Memory (FeRAM) utilizing SPI interface. It operates within a supply voltage range of 1.7V to 1.95V and supports an operating frequency up to 50MHz. The device features high endurance of 10^13 read/write operations per byte and data retention exceeding 5.9 years at +125°C. It includes a unique 64-bit serial number, a special sector region for reflow stability, and block protection capabilities. The component is housed in an 8-pin plastic SOP package with a -40°C to +125°C operating temperature range.
Memory IC Feature Summary
- High endurance supporting 10^13 read/write cycles per byte
- Integrated unique 64-bit serial number and special sector region stable after reflow
- SPI interface compatible with Mode 0 and Mode 3
- Hardware write protect via WP pin and status register configuration
Memory IC Applications
- Automotive applications requiring high-temperature operation
- Systems needing frequent data logging without backup batteries
- Industrial equipment requiring long-term data retention
Memory IC Procurement Notes
Verify the specific ordering suffix matches the required shipping form, as BCE1 indicates tube packaging while BCERE1 indicates tape and reel. Confirm the voltage variant corresponds to the system requirements, as this model specifies a 1.7V to 1.95V supply range. Ensure compatibility with the 8-pin SOP package dimensions during PCB layout.
Memory IC Selection Notes
Select this component when a low-voltage FeRAM solution with SPI interface is required for high-endurance applications. It is suitable for designs needing nonvolatile memory that eliminates write wait times associated with Flash. Consider the 1.7V to 1.95V operating range and ensure the host controller supports the specified SPI modes and clock frequencies.
Memory IC Part Context
This part belongs to the MB85RS512LY series of FeRAM devices from RAMXEED. It shares the core memory architecture with other variants differing primarily in package type and shipping format. The LY designation indicates the specific voltage and temperature characteristics tailored for automotive-grade environments.
Memory IC Replacement Considerations
Direct replacements include MB85RS512LYPNF-G-BCERE1 for tape-and-reel packaging or MB85RS512LYPN-G-AWE1 for DFN packaging. Verify pinout and electrical specifications remain identical before substitution.
