It operates with a 3.3V power supply and offers a data bus width of 16 bits. The "7" in the part number indicates a maximum clock frequency of 143 MHz, allowing for faster data transfer rates suitable for high-performance applications.
This DRAM is organized into a memory array allowing for efficient data storage and retrieval. It supports burst modes, which enhance performance during sequential data accesses. The device is housed in a standard package format, making it compatible with a range of circuit designs.
Typical applications include consumer electronics, networking equipment, and various embedded systems where compact memory solutions are required. Its reliability and speed make it a suitable choice for modern computing needs.

Package

The IS42S16400J-7TL is packaged in a TSOP-II (Thin Small Outline Package) format. This type of package is commonly used for memory devices, featuring a flat, low-profile design suitable for surface mounting on printed circuit boards.

Pinout

The IS42S16400J-7TL is a 16Mb (2M x 8) synchronous dynamic random-access memory (SDRAM) chip. It features a 54-pin TSOP II package.
The main functions of the pins are as follows:
- Data Pins (DQ0-DQ7): 8 data lines for input/output.
- Address Pins (A0-A10): Used for addressing the memory locations.
- Control Pins:
- CS (Chip Select): Activates the chip.
- RAS (Row Address Strobe): Indicates when a row address is valid.
- CAS (Column Address Strobe): Indicates when a column address is valid.
- WE (Write Enable): Controls writing to the memory.
- Clock Pins (CLK, CLK): Inputs for the clock signal to synchronize operations.
- Baud Rate Control Pins (BA0, BA1): For bank selection.
- Refresh Pins (REF): Used for refreshing the memory cells.
This combination of pins allows the IS42S16400J-7TL to function efficiently in various memory applications.
