What are the key features of the MT46H16M16LFBF-6IT:H?
The MT46H16M16LFBF-6IT:H is a 256Mb Mobile DDR SDRAM from Micron Technology. It operates at a low voltage range of 1.70V to 1.95V, making it ideal for power-sensitive applications. The device features a double data rate (DDR) architecture with a clock frequency of up to 166 MHz, delivering two data transfers per clock cycle for high-speed performance. It is organized as 16M x 16 bits with four internal banks that support concurrent operations. Additional features include a bidirectional data strobe (DQS), programmable burst lengths (2, 4, or 8), auto refresh and self refresh modes, an on-chip temperature sensor for dynamic self refresh rate control, partial-array self refresh (PASR), deep power-down (DPD) mode, and a wide industrial temperature range of -40°C to 85°C.
What is the MT46H16M16LFBF-6IT:H used for?
This memory chip is specifically designed for mobile and embedded applications that demand low power consumption along with high memory bandwidth. Typical use cases include smartphones, tablets, portable electronics, IoT devices, automotive infotainment systems, and industrial equipment. Its compact 60-VFBGA package makes it well suited for space-constrained designs, while the industrial temperature rating ensures reliable operation in harsh environments.
Are there any alternative parts for the MT46H16M16LFBF-6IT:H?
Yes, several compatible alternatives are available. The Texas Instruments DLPC2607 documentation lists the following as validated compatible mDDR DRAM options with similar 256Mb density and 16M × 16 organization: Samsung K4X56163PL-FGC6, Samsung K4X56163PN-FGC6, and Elpida EDD25163HBH-6ELS-F. Additional cross-reference sources also indicate that Hynix H5MS2562JFR-J3M and Winbond W948D6FBHX5E can serve as functional replacements, though designers should always verify compatibility with their specific system requirements before substituting.
