MCLogic is a global pioneer in innovative memory technologies and solutions, dedicated to developing world-class memory architectures, core IP, chips, and system-level solutions. The company holds dozens of core patents, and its revolutionary proprietary MCRAM memory architecture and technology can be widely applied across diverse memory systems, delivering breakthrough bandwidth gains, dramatically improved read/write efficiency, and significantly lower power consumption — effectively overcoming the "memory wall" bottleneck. The technology has been deeply deployed in a broad range of fields, including automotive electronics, high-speed network communications, high-reliability industrial control, AI computing, IoT terminals, and wearable devices, providing high-performance, low-power memory foundation solutions for pervasive intelligent applications and continuously driving the evolution of computing infrastructure.
As part of the MC90 SPI NVRAM line, the device writes like a standard SRAM over the serial bus while retaining its contents when power is removed, eliminating battery backups and EEPROM wear-out concerns in parameter storage. MC90N512K0V33BS-IA belongs to MCLogic's SPI NVRAM offering, providing 512K of storage arranged as 64K x 8 in DFN8 5x6mm. It clocks at up to 80Mhz on the serial bus, keeping read and write cycles short during parameter updates.
Simple four-wire SPI interface that integrates easily with mainstream MCUs
Byte-writable over the standard SPI bus, with no page-erase cycle before a write
512K capacity, organized as 64K x 8
The interface sustains 80Mhz clock operation, which keeps configuration writes effectively instantaneous from the system's point of view.
Housed in DFN8 5x6mm, it drops into standard footprints used across the family.
Non-volatile storage with no battery or external power needed for retention
Typical deployments cover factory automation and PLC I/O modules, payment terminals, BMS boards and telecom adjunct cards.
