MT40A512M16JY-083E IT:B
Brand: Micron Technology Inc.
The MT40A512M16JY-083E IT:B is Micron's 8Gb DDR4 SDRAM organized as 512M words x 16 bits, delivering 2400 MT/s (DDR4-2400) data transfer at a low 1.2V supply. As a fourth-generation double data rate synchronous DRAM, it offers higher bandwidth, lower power, and improved reliability over DDR3L — the current standard for new embedded designs. The industrial temperature grade (-40C to +95C) ensures reliable operation in outdoor, automotive, and industrial equipment where commercial-grade memory would fail. The 96-ball FBGA x16 package enables dense multi-chip memory arrays for embedded computing, networking equipment, FPGA processing boards, and industrial controllers.

Product Details
DDR4 vs DDR3L — Why Upgrade Matters
The MT40A512M16JY is fourth-generation DDR SDRAM, delivering fundamental advantages over the previous DDR3L standard:
Lower Power: 1.2V supply versus 1.35V (DDR3L) — approximately 20% lower power consumption at equivalent performance, critical for battery and thermally-constrained systems.
Higher Bandwidth & More Banks: DDR4 supports up to 3200 MT/s (this part: 2400 MT/s) with 16 internal banks versus DDR3's 8, enabling more concurrent memory operations and higher effective bandwidth for data-intensive workloads.

Frequently Asked Questions
What is the MT40A512M16JY-083E IT:B used for?
An 8Gb DDR4 SDRAM (512M x 16) for embedded computing, networking, FPGA memory, and industrial controllers. Provides 2400 MT/s bandwidth at 1.2V with industrial temperature operation for reliable high-speed data buffering.
What does the -083E speed grade mean?
DDR4-2400: 0.833ns clock cycle (1200 MHz) giving 2400 MT/s data rate. This is a mid-range DDR4 speed bin suitable for most embedded and industrial applications.
What does the IT temperature grade mean?
Micron's industrial temperature grade, operating -40C to +95C (case). Essential for outdoor, automotive, and industrial equipment where commercial-grade memory (0C to +85C) would fail or degrade.
How much memory with multiple chips?
Each chip is 8Gbit (1GB) as 512M x 16. Two chips in a 32-bit config yield 2GB; four chips in a 64-bit config yield 4GB. The 96-ball FBGA enables dense multi-chip layouts.
What is the difference between DDR4 and DDR3L?
DDR4 operates at 1.2V (vs 1.35V DDR3L), supports higher data rates, has 16 banks (vs 8), and improved reliability. DDR4 is the current standard for new embedded designs; DDR3L remains for legacy applications.
