IS42S16320B-7TLI

IS42S16320B-7TLI is an ISSI (Integrated Silicon Solution, Inc.) memory device. Key points:
- Type and organization: 64-Mbit synchronous memory, organized as 16M words × 32 bits.
- Interface: Synchronous DRAM/SRAM style with standard SDRAM-style control signals and a burst-capable, high-rate data path.
- Speed/grade: -7 indicates a 7 ns speed grade.
- Packaging/voltage: Typically in a TSOP/lead-free package; operates from a single supply (common 3.3V family devices in this line).
- Features: Banked memory with burst modes, page access, and predictable latency suitable for high-bandwidth applications.
- Typical use: Main memory or cache-like block in embedded systems, DSPs, graphics, and other high-speed computing tasks.
- Documentation: Exact electrical characteristics, pinout, timing, and recommended operating ranges are in the official IS42S16320B-7TLI datasheet from ISSI.
Note: Always verify with the latest ISSI datasheet for precise voltage, temperature range, package type, timing parameters, and recommended operating conditions.

A 54-pin TSOP II (Thin Small Outline Package II).

- Pin count: 54 pins (TSOP-II package)
- Function: 512-Mbit synchronous DRAM (SDRAM) organized as 16,384K × 32-bit. It provides a 32-bit wide data path with standard SDRAM control signals (RAS, CAS, WE, CS, CKE/CK, BA0–BA2, A0–A23) and DQ0–DQ31, typically operating at 3.3V.

Manufacturer: Integrated Silicon Solution, Inc. (ISSI).
ISSI is a US-based fabless semiconductor company that designs and markets memory products (DRAM and SRAM) and relies on external foundries for fabrication.
