IS45S16800E-7TLA1

The IS45S16800E-7TLA1 is a 128 Mbit synchronous DRAM (SDRAM) device organized as 8M × 16 with a parallel LVTTL interface and quad-bank internal architecture. It implements a pipeline, fully synchronous design with registered inputs and outputs referenced to the rising edge of the clock.

Designed for systems that require compact, board-level SDRAM in a 54-pin TSOP II package, the device offers programmable burst lengths and sequence, selectable CAS latency, and refresh/self-refresh modes to support high-speed data transfer and predictable timing behavior.

Key Features

• Memory Core & Organization 128 Mbit SDRAM organized as 8M × 16 with four internal banks (2M ×16 ×4), supporting random column address every clock cycle for efficient memory access.
• Synchronous Pipeline Architecture Fully synchronous operation with all signals referenced to the positive clock edge and pipeline architecture for high-speed data transfer.
• Performance Operates at up to 143 MHz for the –7 speed grade with an access time from clock of 5.4 ns (CAS latency = 3).
• Programmable Burst & Timing Programmable burst lengths (1, 2, 4, 8, full page) and burst sequence (sequential/interleave); programmable CAS latency options of 2 or 3 clocks.
• Refresh & Power Modes Supports Auto Refresh (CBR) and Self Refresh; 4096 refresh cycles per 16 ms (A2 grade) or 64 ms (A1 grade) as specified in the device options.
• Interface & Logic Levels LVTTL-compatible inputs and outputs with a parallel memory interface suitable for standard SDRAM controller implementations.
• Power Supply Operates at a supply range of 3.0 V to 3.6 V with typical 3.3 V VDD and VDDQ operation.
• Package & Mounting 54-pin TSOP II (0.400", 10.16 mm width) package for compact board-level mounting.
• Operating Temperature Specified operating ambient range of –40 °C to +85 °C (TA) for the provided option.

Typical Applications

• Embedded Systems Board-level SDRAM for embedded designs that require a 128 Mbit parallel memory in a compact 54-TSOP II package.
• Communications Equipment Buffer and working memory in systems where synchronous, clocked data transfer and programmable burst behavior are needed.
• Industrial Control Memory for control and data-logging applications that require operation across an ambient range of –40 °C to +85 °C.
• Consumer Electronics On-board SDRAM for devices needing configurable burst lengths and CAS latency options for diverse throughput requirements.

Unique Advantages

• Synchronous, clocked operation: Performance and timing are driven by a positive-edge clock reference, enabling predictable pipeline data transfers at up to 143 MHz.
• Flexible burst and latency control: Programmable burst lengths/sequences and CAS latency options allow designers to tune throughput and latency to match system requirements.
• Compact TSOP II footprint: 54-pin TSOP II package (10.16 mm width) minimizes board area for space-constrained designs while providing a parallel interface.
• Robust refresh and low-power modes: Auto Refresh and Self Refresh support system-level power management and data retention during low-power states.
• Wide operating voltage window: 3.0 V to 3.6 V supply range with typical 3.3 V operation for compatibility with standard memory power domains.
• Extended ambient temperature range: Specified for –40 °C to +85 °C to support designs exposed to a broad range of operating conditions.
