B3221PM3BDGVIW-U

The B3221PM3BDGVIW-U is a mobile LPDDR4 SDRAM device in a 200-ball FBGA package that delivers up to 4266 Mb/s data rate. It implements a two-die 16Gbit configuration to provide a 32 Gbit DRAM device organized as 1024M x 16 x 2 channels with a parallel memory interface.

Designed for low-power mobile-class applications, the device combines DRAM features such as per-bank refresh, programmable latencies and burst lengths, and differential clocks to address designs that require compact, high-bandwidth, low-voltage memory with extended temperature capability.

Key Features

• Memory Architecture — 32 Gbit device composed of two 16 Gbit (x16) die in one package; organization shown as 1024M ×16 ×2 channels and 8 internal banks per channel.
• High Data Rate — Supports data rates up to 4266 Mbps (double-data-rate architecture with two transfers per clock) with a clock frequency listed at 2.133 GHz.
• Burst and Latency Options — Burst lengths 16, 32 and on-the-fly (MRS-enabled); programmable read and write latencies and programmable driver strength for timing optimization.
• Low-Voltage Operation — Dual supply domains: VDD1 = 1.8 V (1.70–1.95 V) and VDD2/VDDCA/VDDQ = 1.1 V (1.06–1.17 V), enabling low-power operation.
• Refresh and Power Management — Supports auto-refresh, self-refresh, per-bank refresh, partial array self-refresh (PASR), bank masking and segment masking; built-in temperature sensor for auto temperature-compensated self-refresh (ATCSR).
• Interface and Signal Integrity — Differential clock inputs (CK_t/CK_c) and bi-directional differential data strobe (DQS_t/DQS_c); DMI pin support for write data masking and DBIdc functionality.
• Compact Package — 200-ball FBGA package (10 × 14.5 mm) suitable for space-constrained board designs.
• Extended Temperature Range — Industrial temperature option rated from −40°C to +95°C (TC) for deployments requiring wider operating range.
• Performance Characteristics — Access time of 3.5 ns and write cycle time (word page) of 18 ns as specified.

Typical Applications

• Mobile Devices — Mobile LPDDR4 technology and high data rate make it suitable for memory subsystems in handheld and mobile platforms that require compact, low-power DRAM.
• Low-Power Embedded Systems — Low-voltage operation and self-refresh/PASR features support embedded designs that prioritize power efficiency and memory retention.
• Industrial Equipment — Availability with an industrial temperature range (−40°C to +95°C TC) supports designs operating in extended-temperature environments.

Unique Advantages

• High-bandwidth LPDDR4 performance: Up to 4266 Mbps data rate with DDR architecture to support bandwidth-sensitive memory operations.
• Scalable density in a single package: Two 16 Gbit die combined to deliver 32 Gbit density without larger package footprints.
• Power-efficient operation: Dual supply domains and self-refresh/PASR reduce runtime and retention power for battery- or energy-constrained designs.
• Flexible timing and signaling: Programmable RL/WL, programmable driver strength, and on-the-fly burst mode enable tuning for system timing and signal-integrity requirements.
• Robust refresh control: Per-bank refresh, bank/segment masking and ATCSR provide granular refresh strategies to optimize performance and power.
• Compact FBGA package: 200-ball FBGA (10 × 14.5 mm) enables high-density board placement while supporting parallel memory interface requirements.
