MT48LC4M16A2B4-7E:G TR

The MT48LC4M16A2B4-7E:G TR is a 64 Mbit volatile SDRAM organized as 4M × 16 with a parallel memory interface. It is supplied in a 54-ball VFBGA (8×8) package and is intended for synchronous DRAM use in systems operating from a 3.0–3.6 V supply.

Designed for synchronous, pipelined operation at up to 133 MHz, the device provides internal banked architecture, programmable burst lengths and standard auto-refresh/self-refresh modes as documented in the product datasheet.

Key Features

• Memory Architecture 4M × 16 organization delivering 64 Mbit of DRAM capacity with 4 internal banks for row access and precharge management.
• SDR SDRAM — Synchronous Operation Fully synchronous operation with signals registered on the positive edge of the system clock and internal pipelined operation allowing column address changes every clock cycle.
• Performance & Timing 133 MHz clock frequency (speed grade -7E). Datasheet timing options include CL = 2-2-2 (15 ns) for the -7E grade; product specification lists an access time of 5.4 ns and a write cycle time (word/page) of 14 ns.
• Power Single-supply operation at 3.0–3.6 V (3.3 V ±0.3 V); supports auto refresh and self-refresh modes per the datasheet.
• Burst and Refresh Modes Programmable burst lengths (1, 2, 4, 8, or full page) plus auto precharge and auto refresh; 64 ms/4096-cycle refresh for commercial devices as documented.
• Package & Mounting 54-ball VFBGA package (8 mm × 8 mm) for compact board-level mounting.
• Operating Conditions Commercial operating temperature range: 0°C to +70°C (TA).

Typical Applications

• PC100/PC133 systems — Use as synchronous DRAM memory in systems designed for PC100 or PC133 timing and performance.
• Embedded and board-level memory — Provides 64 Mbit parallel SDRAM storage in a compact 8×8 VFBGA footprint for space-constrained designs.
• Legacy parallel-memory designs — Drop-in SDRAM option for designs requiring a 4M × 16 parallel memory organization and standard SDR timing.

Unique Advantages

• Compact VFBGA footprint: 54-ball (8×8) VFBGA reduces PCB area for board-level memory implementations.
• Flexible timing options: Speed grade -7E supports 133 MHz operation with CL=2 timing (per datasheet), and programmable burst lengths allow trade-offs between throughput and access latency.
• Standard 3.3 V supply range: Operates across 3.0–3.6 V to align with common 3.3 V system rails.
• Synchronous, pipelined design: Fully synchronous operation with internal pipelining and banked architecture enables efficient column access and row precharge management.
• Built-in refresh and power modes: Auto refresh and self-refresh modes help maintain data integrity across refresh cycles.
