MT48LC8M16A2B4-6A XIT:L TR

The MT48LC8M16A2B4-6A XIT:L TR is a 128 Mbit volatile SDRAM organized as 8M × 16 with a parallel memory interface. It delivers fully synchronous, pipelined operation with internal banks and programmable burst lengths for use in systems that require standard parallel SDRAM memory.

Designed for operation from a single +3.3 V ±0.3 V supply and an operating temperature range of −40°C to +85°C, this device targets applications that need high-speed parallel memory access and robust operating-range support.

Key Features

• Memory Core SDRAM, 128 Mbit capacity organized as 8M × 16 with four internal banks for improved access efficiency.
• Performance Clock frequency up to 167 MHz (speed grade -6A) with a CL = 3 access time of 5.4 ns and a write cycle time (word/page) of 12 ns.
• Interface Parallel memory interface with LVTTL-compatible inputs and outputs; fully synchronous operation with all signals registered on the positive clock edge.
• Burst and Refresh Programmable burst lengths (1, 2, 4, 8, or full page); Auto Precharge including concurrent auto precharge; Auto Refresh with 64 ms / 4,096-cycle refresh.
• Low-Power and Self-Refresh Supports Self Refresh Mode with standard and optional low-power variants to retain state during reduced-power intervals.
• Power Single +3.3 V ±0.3 V supply (specified 3.0 V to 3.6 V).
• Package and Thermal 54-ball VFBGA (8 × 8) package; industrial operating temperature range −40°C to +85°C.

Typical Applications

• Parallel system memory Used as on-board SDRAM in designs requiring a 128 Mbit parallel SDRAM footprint and standard SDRAM timings.
• Embedded controllers and processors Provides external synchronous memory for processors or controllers that use parallel SDRAM interfaces.
• Industrial equipment Suited for systems operating across −40°C to +85°C where a 3.3 V SDRAM solution is required.
• Legacy and refresh designs Drop-in memory option for existing PC100/PC133-class or similar parallel SDRAM designs that require the specified timing and package.

Unique Advantages

• High-speed access: Supports up to 167 MHz clocking and 5.4 ns CL = 3 access time (speed grade -6A), enabling fast read/write responsiveness in parallel-memory systems.
• Flexible burst operation: Programmable burst lengths (including full-page) allow tuning of transfer size for different system throughput requirements.
• Banked architecture: Four internal banks hide row access and precharge latency, improving effective throughput for typical access patterns.
• Standard 3.3 V supply: Operates from a single +3.3 V ±0.3 V supply (3.0 V–3.6 V), simplifying power-rail requirements in legacy and industrial designs.
• Industrial temperature capability: Rated for −40°C to +85°C, enabling deployment in temperature-demanding environments.
• Compact VFBGA package: 54-ball VFBGA (8 × 8) reduces board footprint while providing the required I/O count for parallel SDRAM connections.
