Abstract

What is OptiFlash memory technology?

OptiFlash memory technology is a TI patented technology that enables cost effective and scalable high-performance Microcontrollers (MCU) with external flash. With traditional MCUs the ratio of Flash:SRAM typically ranges between 8:1 to perhaps even 12:1. However, with TI’s AM26x MCUs equipped with OptiFlash and large on-chip SRAM (OCSRAM) and tightly coupled memory (TCM), it is possible to implement a cost optimized system, where the OCSRAM scales efficiently with external on-PCB Flash. Below figure depicts a TI Sitara™ AM26x MCU interfacing to external flash via OptiFlash compared to a traditional MCU architecture.
