MT48LC16M16A2B4-6A XIT:G TR

The MT48LC16M16A2B4-6A XIT:G TR is a 256 Mbit volatile SDRAM device with a parallel memory interface and a 54‑VFBGA (8×8) package. It implements a 16M × 16 memory organization with internal bank architecture and fully synchronous operation for systems that require parallel SDRAM memory.

This device targets designs that need synchronous parallel DRAM with up to 167 MHz clock frequency, single‑supply operation at 3.0–3.6 V, and an extended operating temperature range of −40°C to +85°C.

Key Features

• SDR SDRAM core  Fully synchronous SDRAM architecture with all signals registered on the positive edge of the system clock.
• Memory organization & capacity  256 Mbit total capacity with a 16M × 16 organization and internal banks for improved row access/precharge handling.
• Performance / Timing  Speed grade -6A supporting a 167 MHz clock frequency. Datasheet timing table lists RCD = RP = CL = 3 (18 ns) for the -6A grade; typical access time listed as 5.4 ns.
• Burst & refresh  Programmable burst lengths of 1, 2, 4, 8, or full page; supports auto refresh and self refresh (standard; low‑power variants are available according to datasheet options).
• Voltage & signaling  Single 3.0 V to 3.6 V supply range with LVTTL‑compatible inputs/outputs as described in the datasheet.
• Package  54‑VFBGA (54‑ball VFBGA, 8×8) compact package (supplier device package: 54‑VFBGA (8×8)).
• Operating temperature  Specified operating ambient range of −40°C to +85°C (TA).
• Standards & compliance  Datasheet lists PC100 and PC133 compliance for the 256 Mb family and fully synchronous, pipelined internal operation (as documented for this product family).

Typical Applications

• Parallel memory subsystems  Acts as system DRAM in designs that require a parallel SDRAM interface and 256 Mbit capacity.
• Buffering and frame storage  Serves as a high‑speed buffer or temporary storage element where synchronous access and programmable burst lengths are required.
• Industrial electronics  Suitable for systems operating across −40°C to +85°C that require a 3.0–3.6 V SDRAM solution with 167 MHz clock capability.

Unique Advantages

• High clock capability: Allows operation up to 167 MHz (speed grade -6A), enabling higher throughput in parallel SDRAM systems.
• Flexible burst and bank architecture: Programmable burst lengths and internal banks permit efficient memory access patterns and reduced latency for consecutive column accesses.
• Industrial temperature range: Specified for −40°C to +85°C, supporting deployment in temperature‑sensitive environments.
• Single 3 V supply operation: Operates on a single 3.0–3.6 V supply, simplifying power rail requirements for compatible systems.
• Compact VFBGA package: 54‑ball VFBGA (8×8) package provides a compact footprint for space‑constrained designs.
• Standard SDRAM feature set: Includes auto precharge, auto refresh and self‑refresh options plus LVTTL‑compatible I/O as documented in the product family datasheet.
