MT48LC2M32B2B5-6A:J

The MT48LC2M32B2B5-6A:J is a 64 Mbit SDR SDRAM organized as 2M x 32 with a parallel memory interface in a 90-ball VFBGA package. It implements fully synchronous SDRAM architecture with internal pipelining and banked operation to support high-throughput burst access patterns for commercial embedded systems.

Designed for commercial-temperature applications (0°C to +70°C) and single-supply operation around 3.3 V, this device targets systems requiring compact, parallel SDRAM memory with PC100-compliant timing and programmable burst lengths.

Key Features

• Memory Architecture — 64 Mbit SDRAM organized as 2M × 32 with 4 internal banks; supports parallel interface operation and standard DRAM memory format.
• Synchronous SDRAM Operation — Fully synchronous device with all signals registered on the positive edge of the system clock and internal pipelined operation for column-address changes every clock cycle.
• Performance Grades — Speed grade -6A targets a 167 MHz clock frequency; documented timing includes an access time of 5.4 ns and a write cycle time (word page) of 12 ns.
• Programmable Burst and Latency — Programmable burst lengths (1, 2, 4, 8, or full page) and support for CAS latency values of 1, 2, and 3 to match system timing requirements.
• Refresh and Power Management — Supports auto refresh and self refresh modes; 4096-cycle refresh and options for 64 ms/4096-cycle refresh (commercial) as described in the datasheet.
• Voltage and I/O — Single-supply operation at 3.3 V ±0.3 V (listed supply 3.0 V to 3.6 V) with LVTTL-compatible inputs and outputs.
• Compact Package — 90-ball VFBGA (8 mm × 13 mm) package suitable for space-constrained designs.
• Commercial Temperature Range — Rated for operation from 0°C to +70°C (TA).

Typical Applications

• Commercial Embedded Systems — Parallel SDRAM for general-purpose embedded memory in consumer and commercial electronics operating within 0°C to +70°C.
• PC100-Compatible Designs — Systems requiring PC100-compliant SDRAM timing and synchronous operation.
• Buffering and Frame Storage — Burst-capable SDRAM suitable for data buffering and short-term frame or packet storage where parallel memory access is required.

Unique Advantages

• Deterministic Synchronous Operation: All signals registered on the positive edge of the clock and internal pipelining enable predictable timing for system design.
• Flexible Burst Control: Programmable burst lengths and CAS latency support enable tuning of throughput and latency to match application needs.
• High-Density x32 Organization: 2M × 32 organization delivers 64 Mbit in a single compact device, reducing board area for parallel memory implementations.
• Standard Voltage Range: Single 3.3 V supply with tolerance 3.0 V–3.6 V simplifies power sequencing in legacy and contemporary 3.3 V systems.
• Space-Saving VFBGA Package: 90-ball VFBGA (8×13 mm) provides a small footprint for designs with board space constraints.
• Refresh and Low-Power Modes: Auto refresh and self-refresh support help manage data retention and power during idle periods as specified in the datasheet.
