8 Mbit parallel SRAM in 44-TSOP II — what this part is and where it fits
The RMLV0816BGSB-4S2#HA0 is an 8 Mbit parallel SRAM organized as 512K x 16 bits, with a 45 ns access time and a 2.4 V to 3.6 V supply range. It comes in a 44-TSOP II surface-mount package and is rated for the industrial temperature range of -40°C to 85°C. This is a volatile memory — data is retained only while power is applied — and it uses a standard parallel interface for read and write operations. Typical applications include industrial controllers, telecom line cards, networking equipment, and embedded systems where a 16-bit data bus needs fast, deterministic SRAM for code execution or data buffering.
45 ns access time — bus timing for the 16-bit interface
The 45 ns access time and write cycle time are symmetrical for read and write operations.
Package: 44-TSOP II — footprint and handling
The 44-TSOP II (0.400" body width, 10.16 mm) is a standard thin small-outline package for mid-density parallel SRAM. It is surface-mount, so it reflows with standard lead-free profiles. The Tape & Reel (TR) and Cut Tape (CT) options are the shipping media — the device itself is always the same 44-TSOP II package. Board layout can reuse a 44-pin TSOP II footprint common across multiple SRAM vendors, simplifying second-sourcing.
