IS42S16320D-7BLI

IS42S16320D-7BLI is an ISSI memory device from the IS42S family. It’s a high-density memory IC (the exact organization and data width depend on the device variant) with a fast speed grade (the “-7” typically denotes a 7 ns class). The “BLI” suffix refers to a Pb-free leadless package code.
Key points:
- Type: memory device (Synchronous/DRAM-style interface) designed for embedded/graphic/cache-like applications; it requires a memory controller to issue addresses, bank/select, and timing signals.
- Features: multi-bank organization, burst or page-style access, and standard timing parameters (tRCD, tRP, tCAS, etc.) as defined in the datasheet.
- Electricals/packaging: voltage and pinout depend on the exact variant; the -BLI package indicates a specific leadless package option.
- Applications: frame buffers, graphics memory, caching, or general embedded system memory where density and speed are needed.
For precise details (organization, voltage, timings, pinout, and package), refer to the official ISSI datasheet for IS42S16320D-7BLI. If you want, I can pull a summary of the exact specs.

IS42S16320D-7BLI is a 16M x 32-bit synchronous DRAM (SDRAM) device. Key features:
- Organization: 16M x 32-bit (512 Mb total), 32-bit I/O bus
- Voltage: 3.3V operation
- Banks: 4 banks for parallel access
- Burst: support for burst modes with sequential burst (burst lengths common include 4/8; programmable)
- CAS latency: speed grade -7 (typical CL around 3 for this grade)
- Timing: standard SDRAM timings (tRCD, tRP, tRC) with auto precharge
- Data masking: DQM for byte-lane write masking
- Control: full SDRAM command set (CS, RAS#, CAS#, WE#) with auto-refresh and precharge
- Power-saving: auto power-down/self-refresh options
- Packaging: Pb-free, ISBLi format (BLI)
Note: exact timing figures (tRC, tRCD, tRP), burst options, and voltage margins vary by part revision. For precise values, refer to the official datasheet for IS42S16320D-7BLI.
