IS42S16800F-6BLI

The IS42S16800F-6BLI is a 128-megabit synchronous dynamic random-access memory (SDRAM) from ISSI, Integrated Silicon Solution Inc. Organized as 8M x 16, this volatile memory device operates at clock frequencies up to 166MHz with a 5.4ns access time. The compact 54-TFBGA package measures just 8x8mm, making it suitable for space-constrained designs requiring parallel memory interfaces.

Key Features

• Memory Architecture - 128Mbit capacity organized in an 8M x 16 configuration provides flexible data width for parallel processing applications.
• Performance Specifications - 166MHz clock frequency with 5.4ns access time delivers responsive memory operations for embedded systems requiring moderate-speed volatile storage.
• Power Supply - Operates on 3V to 3.6V supply voltage, compatible with standard 3.3V logic systems commonly used in consumer and industrial electronics.
• Extended Temperature Range - Rated for -40°C to 85°C (TA) operation, supporting deployment in industrial environments with temperature variations.
• Compact Package - 54-pin TFBGA package in an 8x8mm footprint minimizes board space while maintaining reliable ball grid array connections.
• Parallel Interface - Standard parallel memory interface simplifies integration with microcontrollers, processors, and FPGAs using traditional SDRAM protocols.

Typical Applications

• Set-Top Boxes - This SDRAM serves as main memory in digital media players and streaming devices where the 128Mbit capacity handles buffering and UI rendering at 3.3V power levels.
• Embedded Systems - Microcontroller-based designs use this parallel SDRAM for program execution and data storage where the extended temperature range ensures operation in varying environmental conditions.
• Industrial Controls - Factory automation equipment and control systems benefit from the -40°C to 85°C temperature tolerance, maintaining memory reliability in non-climate-controlled installations.
• Consumer Electronics - Portable devices and home appliances incorporate this SDRAM for temporary data storage where the compact 8x8mm package fits tight PCB layouts.

Unique Advantages

• Space-Efficient Design: The 54-TFBGA package delivers 128Mbit capacity in just 64mm², reducing board area compared to larger memory packages.
• Standard Interface Compatibility: Parallel SDRAM interface works with existing controller designs without requiring specialized serial memory protocols or additional support circuitry.
