IS66WVH16M8DBLL-100B1LI

Memory IC Overview

The IS66WVH16M8DBLL-100B1LI is a 128Mb HyperRAM device manufactured by ISSI. It features an 8-bit data bus width and operates at a maximum clock frequency of 100 MHz with a 40 ns access time. The memory organization is 16 M x 8. It supports a supply voltage range of 2.7 V to 3.6 V and has a maximum power current of 60 mA. The component is housed in a 24-ball TFBGA package (6x8 mm) and functions within a temperature range of -40°C to +85°C.

Memory IC Feature Summary

• Implements the HyperBus protocol for reduced signal pin counts using a 12-pin interface.
• Provides DDR operation capability to achieve high throughput performance.
• Designed as a low-power dynamic random-access memory solution suitable for space-constrained applications.

Memory IC Applications

• Portable consumer electronics requiring low pin count memory solutions
• Industrial control systems operating within extended temperature ranges
• Automotive infotainment and instrument cluster displays

Memory IC Procurement Notes

Verify the specific suffix B1LI against the manufacturer's latest datasheet to confirm package type and temperature grade. Ensure compatibility with the host controller's HyperBus interface timing requirements. Check for RoHS compliance status relevant to your region. Confirm availability through authorized distributors as lead times may vary based on production schedules.

Memory IC Selection Notes

Select this part when a 128Mb capacity is required with a narrow 8-bit interface to save PCB routing space. It is appropriate for designs needing DDR speeds up to 100 MHz without complex parallel bus architectures. Consider the 2.7V to 3.6V supply range for standard 3.3V logic systems. Evaluate thermal management needs given the 60 mA maximum current consumption during active operation.

Memory IC Part Context

This component belongs to the IS66WVH series of HyperRAM devices from ISSI. These parts combine DRAM density with SRAM-like ease of use. The series offers various densities and interface options, including OctalRAM variants. This specific model targets applications prioritizing interface simplicity and moderate speed over raw bandwidth.

Memory IC Replacement Considerations

Direct substitutes include other ISSI HyperRAM models such as IS66WVH16M8ALL-166B1LI-TR for higher speed or IS66WVH16M8BLL-100B1LI-TR for parallel interface alternatives. Verify pinout and electrical specifications before substitution.
