MT47H16M16BG-3 IT:B TR

The MT47H16M16BG-3 IT:B TR is a 256 Mbit DDR2 SDRAM organized as 16M × 16 with a parallel memory interface in an 84-ball FBGA (8 × 14) package. It implements DDR2 SDRAM architecture and is offered with industrial temperature capability for applications requiring extended operating temperature range.

This device targets systems requiring compact, low-voltage DDR2 memory with programmable timing and on-die signal integrity features. Key value comes from its DDR2 architecture, industrial temperature rating, and compact FBGA mounting.

Key Features

• Memory Architecture  DDR2 SDRAM organized as 16M × 16 for a total of 256 Mbit; 4 internal banks for concurrent operation.
• Performance  Clock frequency specified at 333 MHz with an access time of 450 ps and a word/page write cycle time of 15 ns.
• Voltage and I/O  Operates from 1.7 V to 1.9 V; datasheet specifies VDD and VDDQ = +1.8 V ±0.1 V with JEDEC-standard 1.8 V I/O (SSTL_18-compatible).
• Timing and Burst Control  Programmable CAS latency and selectable burst lengths (BL = 4 or 8) to tune latency and throughput per system requirements.
• Signal Integrity  DLL to align DQ and DQS transitions with CK and on-die termination (ODT) to improve signal margins; supports JEDEC clock jitter specification.
• Refresh and Reliability  64 ms, 8,192-cycle refresh and four internal banks to support sustained memory operation.
• Package & Mounting  84-ball FBGA (8 mm × 14 mm) package, intended for surface-mount assembly in compact designs.
• Temperature Range  Industrial temperature option with an operating temperature range of -40°C to 95°C (TC).
• Additional Functional Options  Differential data strobe (DQS/DQS#) option, duplicate output strobe (RDQS) option for x8 devices, adjustable data-output drive strength.
• Compliance  Datasheet lists RoHS compliance for offered device options.

Typical Applications

• Industrial and Embedded Systems  Industrial temperature rating and compact FBGA packaging make the device suitable for embedded controllers and industrial electronics that require DDR2 memory in constrained board space.
• Board-Level Memory Subsystems  Used as parallel DDR2 DRAM in memory subsystems where 256 Mbit density and x16 organization are required.
• Compact Consumer or Communication Modules  Small FBGA footprint and low-voltage operation support integration into space-constrained consumer and communication modules that use DDR2 memory.

Unique Advantages

• Industrial Temperature Capability: Designed for -40°C to 95°C (TC), enabling deployment in systems exposed to extended temperature ranges.
• Low-Voltage DDR2 Operation: 1.7 V–1.9 V supply range (VDD and VDDQ = 1.8 V ±0.1 V) reduces power domain requirements in modern system designs.
• Programmable Timing Flexibility: Programmable CAS latency and selectable burst lengths allow designers to balance latency and throughput per application needs.
• Signal Integrity Features: DLL alignment and on-die termination improve data timing and reduce external termination complexity.
• Compact FBGA Packaging: 84-ball FBGA (8 × 14 mm) provides high-density mounting for compact boards while maintaining x16 data width.
• Standardized JEDEC Support: JEDEC-compatible I/O and clock jitter support simplifies integration with standard DDR2 controllers and memory subsystems.
