i5141-TG
1. Introduction
1.1. General description
i5141-TG is a high performance flash memory controller for SD/MMC interface flash memory cards. This chip
is based on iCreate 3rd-generation flash engine to achieve high data transfer rate. The enhanced designs
include high performance CPU, multi-bank flash access, 8/16-bit flash interface, and Reed-Solomon based ECC
capability. Voltage-Regulator, Power-on-reset and RC oscillator are integrated to reduce BOM cost and PCB
area. Typical applications of i5141-TG are SD, miniSD, MMC and RS-MMC memory card.
