IS45S16800F-7CTLA2

The IS45S16800F-7CTLA2 from ISSI is a 128 Mbit volatile SDRAM organized as 8M x 16 with a parallel memory interface. It is supplied in a 54-TSOP II package (0.400", 10.16 mm width) and is designed for applications that require on-board parallel DRAM capacity with standard SDRAM timing and signaling.

Key characteristics include a 143 MHz maximum clock frequency, 5.4 ns access time, 3.0 V–3.6 V supply range, and an extended ambient operating temperature range of -40°C to 105°C (TA), making it suitable for systems requiring moderate speed and wide-temperature operation.

Key Features

• Memory Type — Volatile SDRAM in DRAM format, organized as 8M x 16 for 128 Mbit total capacity.
• Performance — Rated for a clock frequency up to 143 MHz with an access time of 5.4 ns for predictable read/write timing.
• Interface — Parallel memory interface suitable for designs using standard SDRAM signaling and pin-out conventions.
• Power — Nominal supply range of 3.0 V to 3.6 V, compatible with 3.3 V system rails.
• Package — 54-TSOP II package (0.400" / 10.16 mm width) in a standard supplier device package footprint for compact board mounting.
• Temperature Range — Operating ambient temperature from -40°C to 105°C (TA) for extended-environment use.

Typical Applications

• Embedded systems — Provides parallel SDRAM working memory where 128 Mbit capacity and standard SDRAM timing are required.
• Industrial electronics — Suitable for systems that require extended ambient operation up to 105°C and 3.3 V power domains.
• Legacy parallel-memory designs — Fits designs that use a parallel DRAM interface and a 54-TSOP II package footprint.

Unique Advantages

• 128 Mbit density in a compact package: 8M x 16 organization delivers significant on-board DRAM capacity in a 54-TSOP II footprint.
