IS46R16160D-6BLA2

The IS46R16160D-6BLA2 is a 256 Mbit DDR SDRAM organized as 16M × 16 bits in a 60-ball TFBGA (8×13) package. It implements a double-data-rate architecture with on-die DLL and data strobe (DQS) timing to support high-speed bidirectional data transfers referenced to both clock and DQS edges.

Designed for systems that require parallel DDR memory in a compact BGA footprint, this device provides selectable burst lengths, programmable CAS latency and standard refresh modes to support continuous read/write burst operation and flexible timing control.

Key Features

• Core / Memory Organization 256 Mbit capacity organized as 16M × 16 with four internal banks to enable concurrent bank operations and continuous burst access.
• DDR Architecture Double-data-rate operation with two data transfers per clock cycle; DQS is transmitted/received with data and is edge-aligned for READs and centre-aligned for WRITEs.
• Timing and Latency Programmable CAS latency options (2, 2.5 and 3) and burst lengths of 2, 4 and 8; commands are registered on the positive edge of CLK and data/masks are referenced to DQS edges.
• Interface and Signalling SSTL_2-compatible I/O, differential clock inputs (CK and CK̄) and Data Mask (DM) for masking write data on both DQS edges.
• Power VDD and VDDQ nominal 2.5 V (±0.2 V); supply operating range listed as 2.3 V to 2.7 V in the product specification.
• Performance Clock frequency rating around 166 MHz for the -6 speed grade and access timing characteristics including 700 ps access time and 15 ns write cycle time (word page).
• Refresh and Reliability Supports Auto Refresh and Self Refresh modes, Auto Precharge and TRAS lockout (tRAP = tRCD) for standard DRAM maintenance and timing control.
• Package and Temperature 60-TFBGA (8×13) ball BGA package; operating temperature range specified as –40°C to +105°C (TA).

Typical Applications

• DDR memory subsystems — Used as parallel DDR SDRAM in systems requiring 256 Mbit of DDR memory with programmable latency and burst control.
• Compact board-level designs — 60-ball TFBGA (8×13) package suits space-constrained PCBs that require high-density parallel memory.
• High-rate data buffering — Double-data-rate architecture and DQS-aligned transfers support continuous read/write burst operation for buffering tasks.

Unique Advantages

• DDR double-data-rate transfers — Two data transfers per clock cycle increase effective bandwidth compared to single-rate memories without changing clock speed.
• Flexible timing configuration — Programmable CAS latencies (2, 2.5, 3) and multiple burst lengths (2, 4, 8) enable tuning for system timing and throughput requirements.
• SSTL_2-compatible I/O and differential clocking — Industry-standard signaling options simplify integration into SSTL_2-capable interfaces and systems using differential clocks.
• Robust refresh and power modes — Auto Refresh and Self Refresh modes plus Auto Precharge and TRAS lockout provide standard DRAM maintenance for reliable operation.
• Wide supply and temperature windows — Supply range of 2.3 V–2.7 V with an operating temperature of –40°C to +105°C supports a range of board- and environment-level requirements.
• Compact BGA footprint — 60-TFBGA (8×13) package delivers 256 Mbit density in a compact form factor for space-limited designs.
