MT46V32M16P-5B L:J TR

The MT46V32M16P-5B L:J TR is a 512 Mbit DDR SDRAM organized as 32M × 16 with a parallel interface in a 66‑pin TSSOP (0.400", 10.16 mm width) package. It implements an internal, pipelined double-data-rate architecture that performs two data accesses per clock cycle, making it suitable for commercial electronic designs that require compact board-level DDR memory.

Key attributes include operation from 2.5 V to 2.7 V, a commercial temperature rating of 0 °C to 70 °C, and a speed grade (-5B) supporting clock operation up to 200 MHz (CL = 3).

Key Features

• Core & memory architecture Internal pipelined DDR architecture with double-data-rate operation and four internal banks for concurrent operation; organized as 32M × 16 (512 Mbit).
• Performance & timing Speed grade -5B supports clock rates up to 200 MHz (CL = 3); specified access time 700 ps and write cycle time (word page) of 15 ns.
• Data capture & timing alignment Bidirectional data strobe (DQS) transmitted/received with data (x16 devices provide two DQS, one per byte); on-chip DLL aligns DQ and DQS transitions with CK for source‑synchronous capture.
• Interface & signaling Differential clock inputs (CK/CK#) with commands entered on each positive CK edge; 2.5 V I/O compatible with SSTL_2 signaling.
• Data control & burst Data mask (DM) support (x16 has two masks, one per byte) and programmable burst lengths of 2, 4, or 8 for flexible data transfer patterns.
• Refresh & power modes Supports auto refresh and standard self refresh; 8192 refresh cycles per 64 ms for commercial temperature rating.
• Power supply VDD and VDDQ recommended range +2.5 V ±0.2 V (device specified across 2.5 V–2.7 V operation).
• Package & thermal 66‑pin TSSOP package (0.400" / 10.16 mm width) specified for commercial operation from 0 °C to 70 °C.

Typical Applications

• Board-level DDR memory for commercial electronics — Compact 66‑TSSOP footprint provides 512 Mbit DDR capacity for space-constrained commercial systems operating at 0 °C to 70 °C.
• Embedded systems with parallel DDR interfaces — 32M × 16 organization and parallel DDR signaling accommodate designs that require x16 data widths and source-synchronous capture.
• OEM memory modules and upgrades — Standard DDR features (DLL, DQS, data mask, programmable burst lengths) enable integration into legacy and custom memory subsystems.

Unique Advantages

• Double-data-rate throughput: Two data accesses per clock cycle deliver higher effective bandwidth compared with single-data-rate devices at the same clock.
• High-frequency capability: Speed grade -5B supports operation up to 200 MHz (CL = 3), enabling higher data rates in compatible systems.
• Byte-level data strobe and masking: Two DQS and two DM signals on x16 devices allow per-byte data capture and write masking for flexible data handling.
• SSTL_2-compatible I/O: 2.5 V I/O signaling aligns with SSTL_2 voltage ranges, simplifying interface design for standard DDR signaling environments.
• Compact surface-mount package: 66‑pin TSSOP (0.400") provides a small board footprint while maintaining a full-featured DDR interface.
• Commercial temperature qualification: Rated for 0 °C to 70 °C to match typical commercial electronic product requirements.
