Overview of IS45S16320D-6CTLA1 – IC DRAM 512MBIT PAR 54TSOP II
The IS45S16320D-6CTLA1 is a 512 Mbit synchronous DRAM (SDRAM) organized as 32M × 16 with a parallel memory interface. It uses a pipeline architecture and fully synchronous timing referenced to the rising edge of the clock to enable high-speed data transfer.
Designed for applications requiring a 512 Mbit SDRAM with programmable burst control and internal bank management, this device delivers deterministic access characteristics and supports operation across an extended temperature range.
Key Features
- Memory Organization and Capacity — 512 Mbit total capacity arranged as 32M × 16, providing a wide parallel data path for high-throughput systems.
- Synchronous Pipeline Architecture — Fully synchronous operation with all signals referenced to the positive clock edge; internal bank structure hides row access/precharge to improve effective throughput.
- Performance — Rated clock frequency for this device is 166 MHz with an access time from clock of 5.4 ns (CAS latency = 3 at -6 speed grade).
- Programmable Burst and CAS — Supports programmable burst lengths (1, 2, 4, 8, full page) and selectable burst sequence (sequential/interleave); programmable CAS latency of 2 or 3 clocks.
- Refresh and Power Management — Auto-Refresh and Self-Refresh supported with 8K refresh cycles per 64 ms for standard operation.
- Interface and Signaling — Parallel memory interface with LVTTL-compatible signaling.
- Voltage Range — Operational supply range of 3.0 V to 3.6 V.
- Package — Supplied in a 54-pin TSOP-II package (0.400", 10.16 mm width) suitable for compact board-level designs.
- Operating Temperature — Rated for operation from −40°C to +85°C (TA).
Typical Applications
- System Memory Expansion — Use as a 512 Mbit SDRAM in systems requiring parallel DRAM memory for high-throughput data buffering and storage.
- High-Speed Data Buffers — Suitable for applications that benefit from synchronous pipeline operation and internal bank management to improve sustained data transfer.
- Industrial-Temperature Designs — Applicable in designs that require memory operation across −40°C to +85°C ambient temperatures.
Unique Advantages
- Deterministic Synchronous Timing: Fully synchronous clock-referenced operation simplifies timing analysis and system integration.
- Flexible Burst Control: Programmable burst lengths and sequence options allow tuning for sequential or random access patterns.
- Internal Bank Architecture: Banked memory hides row access/precharge cycles to improve effective throughput for burst operations.
- Compact TSOP-II Package: 54-pin TSOP-II footprint provides a space-efficient solution for board-level memory implementations.
- Extended Temperature Range: Rated for −40°C to +85°C to support applications operating across a wide ambient temperature window.
- Wide Supply Tolerance: Operates from 3.0 V to 3.6 V to accommodate common 3.3 V system power rails.
