Overview of IS45S16400F-7TLA2-TR – IC DRAM 64MBIT PAR 50TSOP II
The IS45S16400F-7TLA2-TR is a 64‑Mbit synchronous DRAM organized as 1,048,576 × 16 × 4 banks (4M × 16). It implements a fully synchronous pipeline architecture with all signals referenced to the rising clock edge to support high‑speed, predictable memory transfers.
Suited for systems that require parallel SDRAM storage in a compact TSOP II package, this device offers selectable performance options, refresh modes and low access latency for embedded and industrial memory buffering tasks.
Key Features
- Core / Architecture Fully synchronous SDRAM with pipeline architecture and internal bank structure for improved throughput and bank interleaving.
- Memory Organization 64‑Mbit capacity organized as 1,048,576 × 16 × 4 banks (4M × 16) providing a parallel 16‑bit data path.
- Clock and Timing Supports clock frequencies including 200, 166, 143 and 133 MHz options; programmable CAS latency of 2 or 3 clocks and access time down to 5.4 ns (CL‑3, -7 speed grade).
- Burst and Sequence Control Programmable burst lengths (1, 2, 4, 8, full page) with selectable sequential or interleave burst sequences and burst termination commands.
- Refresh and Self‑Refresh Auto refresh (CBR), self‑refresh modes and 4096 refresh cycles per specified interval (64 ms for commercial/industrial/A1 grades, 16 ms for A2 grade) as defined in the datasheet.
- Interface and Signaling Standard parallel DRAM interface with LVTTL signaling and random column address capability every clock cycle.
- Power Single 3.3 V power supply (specified 3.0 V to 3.6 V) for core and I/O operation.
- Package 50‑TSOP II package (0.400" / 10.16 mm width) for compact board-level integration.
- Operating Temperature Rated for operation from −40 °C to +105 °C (TA), supporting extended temperature use cases.
Typical Applications
- Industrial Embedded Systems — Extended −40 °C to +105 °C operating range and robust refresh options make it suitable for industrial memory buffering and control applications.
- High‑speed Buffering — Synchronous pipeline architecture, programmable CAS latency and burst modes support short latency buffering in data path designs.
- Communications and Networking — Parallel SDRAM interface and banked organization enable predictable, high‑throughput temporary storage for packet or frame buffering.
Unique Advantages
- Flexible performance scaling: Multiple supported clock frequencies and selectable CAS latency let designers balance throughput and timing for target system requirements.
- Low access latency: Access times as low as 5.4 ns (CL‑3, -7 grade) reduce read latency in time‑sensitive memory operations.
- High density in a compact package: 64‑Mbit capacity in a 50‑TSOP II footprint conserves PCB space while delivering a 16‑bit parallel data path.
- Comprehensive refresh modes: Auto and self‑refresh options with defined refresh cycle counts support reliable data retention across operating conditions.
- Simplified system integration: Single 3.3 V supply and LVTTL interface ease power and logic interfacing on common embedded platforms.
