MT48LC4M16A2B4-6A IT:J TR

The MT48LC4M16A2B4-6A IT:J TR is a volatile SDRAM device organized as 4M × 16 for a total capacity of 64 Mbit. It implements fully synchronous SDRAM architecture with a parallel memory interface and is offered in a 54-ball VFBGA package (8 × 8).

Designed for systems that require a parallel SDRAM memory element with industrial temperature operation and support for PC100/PC133-class timing, this device provides standard SDRAM functions and timing options to integrate into synchronous memory subsystems.

Key Features

• Memory Type & Organization 64 Mbit SDRAM organized as 4M × 16 (DRAM, volatile) for parallel memory implementations.
• Performance & Timing Supports a clock frequency up to 167 MHz (speed grade -6A) with documented timing (e.g., CL and RCD values in the datasheet) and an access time of 5.4 ns.
• Burst and Internal Operation Fully synchronous operation with internal, pipelined architecture and programmable burst lengths (BL = 1, 2, 4, 8, or full page) as described in the device family datasheet.
• Refresh & Power Management Auto refresh and self-refresh modes are supported (standard and low-power modes available in device family options) with standard 4096-cycle refresh intervals per device family documentation.
• Voltage & I/O Single-supply operation from 3.0 V to 3.6 V; LVTTL-compatible inputs and outputs are part of the device family feature set.
• Package 54-ball VFBGA package, 8 × 8 mm footprint (54‑VFBGA), suitable for compact board layouts.
• Industrial Temperature Range Rated for operation from −40°C to +85°C (TA), matching the IT industrial grade marking in the part number.
• Write Cycle Word/page write cycle time of 12 ns as specified in product parameters.

Typical Applications

• Parallel SDRAM systems — For designs requiring a 64 Mbit parallel SDRAM (4M × 16) memory device with standard SDRAM control and burst modes.
• Industrial-temperature designs — Suitable for systems that require operation across −40°C to +85°C.
• Compact board-level memory — The 54-ball VFBGA (8 × 8) package supports denser board layouts where a small-footprint DRAM is needed.

Unique Advantages

• Standard SDRAM feature set: Implements fully synchronous, pipelined SDRAM behavior with programmable burst lengths and internal bank architecture, enabling conventional SDRAM control schemes.
• High-frequency operation: Speed grade -6A support at 167 MHz provides timing headroom aligned with PC100/PC133-class family timing documented in the datasheet.
• Industrial temperature rating: −40°C to +85°C operation allows deployment in temperature-sensitive environments.
• Compact VFBGA package: 54-ball 8 × 8 VFBGA reduces PCB area, aiding designs with tight real-estate constraints.
• Standard 3.3 V supply range: 3.0 V to 3.6 V single-supply operation simplifies power rail integration for systems using LVTTL-level signaling.
