MB85RC512TPNF-G-JNE1

Memory IC Overview

The MB85RC512TPNF-G-JNE1 is a 512Kbit (64 K x 8) Ferroelectric Random Access Memory (FeRAM) integrated circuit manufactured by RAMXEED. It utilizes a two-wire I2C serial interface and operates within a supply voltage range of 1.7 V to 3.6 V. The device supports standard, fast, and high-speed modes with maximum clock frequencies up to 3.4 MHz. It features a write endurance of at least 10^13 cycles per byte and data retention exceeding 10 years at +85°C. The component is housed in an 8-pin plastic SOP package and functions as an I2C slave device.

Memory IC Feature Summary

• Nonvolatile memory architecture eliminates the need for backup batteries while providing high-speed write operations without polling wait times.
• I2C serial interface allows connection of up to eight devices on the same bus using configurable hardware address pins.
• Hardware write protect pin enables global protection of the memory array against unintended writes.
• Low-power operation includes standby and sleep modes to minimize current consumption during idle periods.

Memory IC Applications

• Data logging systems requiring frequent write cycles
• Industrial control equipment needing reliable nonvolatile storage
• Smart metering applications with low power constraints

Memory IC Procurement Notes

Verify the specific ordering suffix JNE1 corresponds to the tube packaging format required for your assembly process. Confirm that the manufacturer designation matches RAMXEED, as this entity succeeded Fujitsu Semiconductor Memory Solutions Limited. Ensure compatibility with existing I2C bus configurations regarding voltage levels and pull-up resistor requirements before finalizing procurement.

Memory IC Selection Notes

Select this component when a nonvolatile memory solution requires high write endurance and immediate data availability without programming delays. It is suitable for designs utilizing I2C communication protocols where space is limited by the 8-pin SOP footprint. Consider the operating voltage range and temperature specifications to ensure alignment with the target system environment.

Memory IC FAQ

Does the MB85RC512TPNF-G-JNE1 require an acknowledge polling sequence after writing?

No, the device performs high-speed write operations, so any waiting time for an ACK polling does not occur.

How many devices can be connected to the same I2C bus using this component?

Up to eight devices can be connected to the same data bus, identified by unique combinations of the A0, A1, and A2 hardware address pins.

What is the function of the WP pin?

The Write Protect (WP) pin disables writing operations when set to a high level. When low or open, the entire memory region can be overwritten, though reading remains enabled regardless of the pin state.
