MB85RC04VPNF-G-JNE1

Memory IC Overview

The MB85RC04VPNF-G-JNE1 is a 4 Kbit (512 words x 8 bits) Ferroelectric Random Access Memory (FeRAM) manufactured by RAMXEED. It utilizes a two-wire I2C serial interface with a maximum operating frequency of 1 MHz. The device operates within a supply voltage range of 3.0 V to 5.5 V and supports an ambient temperature range from -40 °C to +85 °C. It features a write endurance of at least 10^12 cycles per byte and data retention exceeding 10 years at +85 °C. The component is housed in an 8-pin plastic SOP package.

Memory IC Feature Summary

• Nonvolatile memory architecture eliminates the need for backup batteries while retaining data without power.
• High-speed write operations remove the requirement for polling sequences or programming wait times after writing.
• Hardware write protection allows disabling write operations via the WP pin while maintaining read access.
• Internal pull-down resistors on address pins simplify bus configuration for multi-device connections.

Memory IC Applications

• Industrial systems requiring frequent data logging and high rewrite endurance
• Embedded controllers utilizing I2C communication protocols
• Data storage applications needing immediate power-on accessibility

Memory IC Procurement Notes

Verify the specific suffix JNE1 corresponds to the tube packaging format, as other suffixes indicate tape and reel options. Confirm RoHS compliance status through official documentation prior to integration. Ensure ESD handling procedures are followed during assembly due to semiconductor sensitivity. Cross-reference the manufacturer part number with current product change notifications to verify active production status.

Memory IC Selection Notes

Select this component when a nonvolatile memory solution requires high endurance beyond standard EEPROM capabilities. The I2C interface suits designs with limited GPIO availability. Consider the 3.0 V to 5.5 V operating range for compatibility with various logic levels. Evaluate the 8-pin SOP footprint against available PCB space constraints.
