MT48LC2M32B2B5-7 IT:G

The MT48LC2M32B2B5-7 IT:G is a 64 Mbit SDR SDRAM organized as 2M × 32 with a parallel memory interface in a 90-ball VFBGA (8 mm × 13 mm) package. It provides fully synchronous DRAM operation with internal banking and pipelined access for systems requiring a compact, parallel SDRAM solution.

Key attributes include a 143 MHz clock frequency, 3.0–3.6 V supply range (single 3.3 V ±0.3 V), an industrial operating temperature range of −40°C to +85°C, and timing options that support programmable burst lengths and selectable CAS latencies.

Key Features

• Memory Architecture 64 Mbit capacity organized as 2M × 32 with 4 internal banks (512K × 32 × 4 banks).
• SDR SDRAM Core Fully synchronous operation with all signals registered on the positive edge of the system clock and internal pipelined operation for column-address changes every clock cycle.
• Performance & Timing Clock frequency listed at 143 MHz with an access time of 5.5 ns; supports CAS latencies (CL) of 1, 2, and 3 and programmable burst lengths of 1, 2, 4, 8 or full page.
• Refresh and Power Modes Auto refresh and self-refresh modes (self refresh not available on AT devices); 64 ms/4096-cycle refresh supported for commercial and industrial grades.
• Interface & I/O Parallel memory interface with LVTTL-compatible inputs and outputs (per datasheet feature listing).
• Supply Voltage Single supply operation at 3.0 V to 3.6 V (3.3 V ±0.3 V specified).
• Package 90-ball VFBGA, 8 mm × 13 mm footprint (Supplier device package: 90-VFBGA (8×13)).
• Temperature Range Industrial operating temperature: −40°C to +85°C (TA).

Unique Advantages

• Compact BGA footprint: 90-ball VFBGA (8×13) enables space-constrained board designs while delivering parallel SDRAM capacity.
• Flexible timing and burst control: Programmable burst lengths and support for multiple CAS latencies allow tuning for system timing and throughput requirements.
• Industrial temperature tolerance: Specified operation from −40°C to +85°C supports deployment in industrial environments.
• Single 3.3 V supply: Operates across a 3.0–3.6 V range (3.3 V ±0.3 V), simplifying power-rail design in legacy 3.3 V systems.
• Synchronous, pipelined access with internal banks: Internal bank architecture and pipelined operation help optimize row/column access sequencing within parallel SDRAM systems.

Why Choose MT48LC2M32B2B5-7 IT:G?
