M55D1G1664A-EEBIG2Y

The M55D1G1664A-EEBIG2Y is a 1.074 Gbit LPDDR3 SDRAM organized as 64M × 16 with eight internal banks and JEDEC LPDDR3 compliance. It delivers double-data-rate operation at a maximum clock frequency of 933 MHz (1866 Mb/s per pin data rate) with support for industrial temperature operation from −40 °C to 85 °C.

Designed for industrial-grade memory subsystems, this device offers low-voltage core and I/O operation, advanced DDR features for timing calibration, and a compact 178-ball BGA package for surface-mount integration.

Key Features

• Memory Organization — 1.074 Gbit capacity arranged as 64M × 16 with 8 banks and a 4KB page size, supporting high-density memory mapping for embedded systems.
• Performance — Operates up to 933 MHz clock frequency (1866 Mb/s per pin) with selectable read latencies (RL options include 3, 6, 8, 9, 10, 11, 12, 14, 16) and a burst length of 8 for sustained data throughput.
• Low-Voltage Power Domains — Separate supply domains: VDD1 = 1.70–1.95 V and VDD2 / VDDCA / VDDQ = 1.14–1.30 V, enabling lower-power operation for core and I/O.
• DDR Architecture & I/O — Eight-bit prefetch DDR architecture, bidirectional/differential per-byte DQS strobes, differential clock inputs (CK_t/CK_c), and data mask (DM) support for reliable high-speed transfers.
• Timing and Training — Supports CA training and write leveling for clock-to-DQ, DQS and DM timing adjustment, improving interface margin in system designs.
• Advanced Power & Refresh — Per-bank refresh, auto temperature compensated self refresh (ATCSR), partial-array self refresh (PASR), deep power-down (DPD), and standard auto/self refresh modes for flexible power management.
• System Controls — Programmable drive strength (DS), on-die termination (ODT), bank masking, and segment masking for optimized signal integrity and power/performance trade-offs.
• Package & Mounting — Pb-free 178-ball BGA (10 × 11.5 mm) surface-mount package suitable for compact board-level integration in industrial designs.

Typical Applications

• Industrial Systems — Provides JEDEC LPDDR3 memory in designs that require operation across −40 °C to 85 °C and robust refresh/power management features.
• Embedded Memory Subsystems — Suitable for controllers and modules that need a 1Gb LPDDR3 device with per-bank refresh and advanced power states like deep power-down and self-refresh.
• High-Speed Interfaces — Useful where differential clocks, per-byte DQS, and write leveling/CA training are required to maintain timing margin at high data rates.

Unique Advantages

• Industrial Temperature Range — Guaranteed operation from −40 °C to 85 °C for deployment in temperature-challenging environments.
• Low-Voltage Dual Supply — Separate core and I/O voltage ranges (VDD1 and VDD2/VDDCA/VDDQ) enable optimized power distribution and reduced power consumption.
• JEDEC LPDDR3 Compliance — Conforms to LPDDR3 standards with features such as eight internal banks, BL8 bursts, and standard refresh mechanisms for predictable system behavior.
• High Data Rate Capability — 933 MHz clocking (1866 Mb/s per pin data rate) with flexible read-latency options to match system timing requirements.
• Comprehensive Power Management — ATCSR, PASR, DPD and per-bank refresh modes provide designers with multiple strategies to balance power vs. availability.
• Compact, Pb-free BGA — 178-ball BGA (10 × 11.5 mm) package offers high density and Pb-free compliance for modern assembly processes.
