IS46R86400F-6TLA1

The IS46R86400F-6TLA1 is a 512 Mbit volatile DRAM organized as 64M × 8 and implemented using DDR SDRAM technology. It provides a synchronous SSTL_2 memory interface with a 166 MHz clock frequency and is supplied in a 66‑TSSOP (66‑TSOP II) package.

Targeted for designs requiring a compact, automotive‑grade DDR memory component, this device offers AEC‑Q100 qualification, a wide operating temperature range, and a supply voltage window of 2.3 V to 2.7 V.

Key Features

• Memory Core  512 Mbit DRAM organized as 64M × 8 for byte-wide data paths.
• Technology & Interface  SDRAM – DDR technology with an SSTL_2 memory interface suitable for SSTL_2 signaling environments.
• Performance  166 MHz clock frequency with a 700 ps access time and a 15 ns write cycle time (word page), providing defined timing characteristics for system integration.
• Power  Operates from a 2.3 V to 2.7 V supply range, enabling use in systems designed around this DDR supply window.
• Package & Mounting  Supplied in a 66‑TSSOP (66‑TSOP II) package (0.400", 10.16 mm width) for board‑level mounting where this package footprint is required.
• Temperature & Qualification  Rated for -40°C to 85°C ambient (TA) and qualified to AEC‑Q100.

Typical Applications

• Automotive memory subsystems  AEC‑Q100 qualification and a -40°C to 85°C operating range make the device suitable for automotive electronic module designs that require DDR memory.
• SSTL_2 interface systems  Use in boards and modules that implement SSTL_2 signaling for synchronous DDR memory interfacing.
• Space‑constrained PCB designs  The 66‑TSSOP (66‑TSOP II) package supports installations where a compact TSOP footprint is required.

Unique Advantages

• AEC‑Q100 qualified: Automotive qualification is provided explicitly by AEC‑Q100 certification, supporting use in qualified automotive designs.
• Wide ambient temperature range: Rated from -40°C to 85°C (TA) to meet thermal requirements of harsher environments.
• SSTL_2 signaling compatibility: Native SSTL_2 memory interface simplifies integration into systems using this standard.
• Defined timing performance: 166 MHz clock rate, 700 ps access time and 15 ns write cycle time (word page) offer clear timing parameters for system timing budgets.
• Compact package: 66‑TSSOP (66‑TSOP II) package (10.16 mm width) enables implementation where a TSOP footprint is needed.
• Industry standard DDR SDRAM: DDR SDRAM architecture with 64M × 8 organization supports common byte‑wide memory mapping requirements.
