Description
IS42S16320B-7TLI is a high-speed synchronous DRAM (SDRAM) device from ISSI/Intersil. It is a 3.3V memory with a 16,384-word by 32-bit (16K × 32) organization, operating at the -7 speed grade (roughly a 7 ns cycle time). The “TLI” suffix indicates a lead-free TSOP-II style package.
Key points:
- Interface: standard SDRAM signals (CLK, CS, RAS, CAS, WE, and DQ[31:0]), with multiplexed address/data.
- Features: multi-bank architecture, burst read/write modes, programmable CAS latency (typical CL=2/3 in SDRAMs), auto-refresh, and internal bank management.
- Power and temp: typically 3.3V supply; temperature range depends on exact device revision.
- Applications: main/system memory for embedded processors, graphics controllers, networking gear, and other high-rate memory needs.
For exact organization, timings, number of banks, refresh specs, and package details, consult the official datasheet. This is a concise introduction; specs vary by revision.
