Infineon CY62148E Series SRAM, 4MB Memory Size, 1MHz Maximum Clock Frequency - CY62148ELL-55SXI
This SRAM is a static memory device designed for short-term data storage in electronic systems. It operates within typical embedded environments where quick read/write access and simple timing are required. The device is supplied as a surface-mount SOIC package and is intended for designs requiring non-volatile-free volatile memory with an 8-bit data path and 512K words of capacity.
Features and Benefits:
• Asynchronous 45 ns access time delivers fast random reads and writes
• Supports up to 1 MHz clock frequency for responsive memory cycles
• 5.5V maximum supply allows compatibility with higher-voltage systems
• 4.5V minimum supply enables reliable low-voltage operation
• 20 mA supply current provides predictable power budgeting
• Operating range -40 to 85 °C suits deployment across industrial temperatures
• Supports up to 1 MHz clock frequency for responsive memory cycles
• 5.5V maximum supply allows compatibility with higher-voltage systems
• 4.5V minimum supply enables reliable low-voltage operation
• 20 mA supply current provides predictable power budgeting
• Operating range -40 to 85 °C suits deployment across industrial temperatures
Applications
• Suitable for buffering in microcontroller-based systems
• Ideal for temporary data logging in industrial equipment
• Used with control units requiring 8-bit parallel data transfer
• Can be used for firmware shadow RAM in legacy electronics
• Suitable for surface-mount assemblies where SOIC is required

How is addressing organised for system integration?
The memory is arranged as 512K words of 8 bits, accessed through an 8-bit address bus width allowing straightforward byte-oriented addressing.
What package considerations affect PCB layout?
The device is supplied in a 32-pin SOIC surface-mount package, which informs footprint, solder paste mask and thermal considerations during PCB design.
How does the device behave thermally during operation?
It is specified for use from -40 °C to 85 °C, so thermal design should account for ambient extremes and power dissipation driven by its 20 mA supply current.
What pin-count and signalling style should I expect?
The component uses a 32-pin configuration and operates with asynchronous timing, which simplifies timing constraints compared with synchronous memory.
