MB85R8M1TABGL-G-JAE1

Memory IC Overview

The MB85R8M1TABGL-G-JAE1 is an 8 Mbit Ferroelectric Random Access Memory (FeRAM) organized as 1,048,576 words by 8 bits. It utilizes a pseudo-SRAM parallel interface and operates within a supply voltage range of 1.8 V to 3.6 V. The device supports read/write endurance of 10^14 operations per 64 bits and ensures data retention for up to 200 years at +35 °C. It functions in ambient temperatures from -40 °C to +85 °C and is housed in a 48-pin plastic FBGA package.

Memory IC Feature Summary

• Nonvolatile memory architecture utilizing ferroelectric process technology that retains data without backup power.
• High endurance capability supporting 10^14 read/write cycles per 64 bits, exceeding Flash and EEPROM limits.
• Pseudo-SRAM parallel interface enabling direct replacement for SRAM applications with simplified integration.
• Low power consumption features including standby current of 150 μA maximum and sleep mode operation.

Memory IC Applications

• Data logging systems requiring high write endurance and nonvolatile storage.
• Industrial control units needing reliable memory in varying temperature environments.
• Embedded systems replacing volatile SRAM where battery backup is impractical.

Memory IC Procurement Notes

Verify the specific ordering suffix matches the required package type, as this part number corresponds to the 48-pin FBGA variant. Confirm moisture sensitivity level requirements for surface mount assembly processes. Ensure the design accounts for the recommended programming sequence after reflow to guarantee data integrity. Check for any product change notifications regarding material or packaging updates before finalizing procurement.

Memory IC Selection Notes

Select this component when a parallel interface is preferred over serial protocols like SPI or I2C. It is suitable for designs requiring fast random access times comparable to SRAM but with nonvolatile characteristics. Consider the 48-pin FBGA package constraints for PCB layout and thermal management. Evaluate power budget against the specified operating and standby currents to ensure compliance with system energy constraints.
