MB85RC512TPNF-G-AMERE2

Memory IC Overview

The MB85RC512TPNF-G-AMERE2 is a 512Kbit (64 K x 8) Ferroelectric Random Access Memory (FeRAM) integrated circuit manufactured by RAMXEED. It utilizes a two-wire serial I2C interface and operates within a supply voltage range of 1.7 V to 3.6 V. The device supports standard, fast, fast mode plus, and high-speed modes with a maximum clock frequency of 3.4 MHz. It features a write endurance of at least 10^13 cycles per byte and data retention of 10 years at +85°C. The component is housed in an 8-pin plastic SOP package with a 150mil lead pitch.

Memory IC Feature Summary

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

Memory IC Applications

• Data logging systems requiring frequent write cycles
• Industrial control equipment with limited power budgets
• Smart metering applications needing long-term data retention

Memory IC Procurement Notes

Verify the specific ordering suffix AMERE2 corresponds to the embossed carrier tape packaging format. Confirm that the required shipping quantity aligns with the manufacturer's minimum shipping specifications for this tape variant. Ensure compatibility with the 8-pin SOP 150mil footprint during PCB layout verification.

Memory IC Selection Notes

Select this component when a nonvolatile memory solution requires high endurance and fast write speeds without complex programming wait times. The I2C interface is suitable for systems with limited GPIO availability. Consider the 1.7 V to 3.6 V operating range for low-voltage designs. Verify that the 8-pin SOP package fits the available board space constraints.

Memory IC FAQ

Does the MB85RC512TPNF-G-AMERE2 require an acknowledge polling sequence after writing?

No, the device performs high-speed write operations and does not require any waiting time or acknowledge polling sequence after issuing a stop condition.

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

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

What is the function of the WP pin?

The Write Protect (WP) pin disables write operations when set to a high level. Reading remains enabled regardless of the pin state. The pin is internally pulled down to recognize a low level if left open.
