Overview

The AS6C4016-55BIN is a 4Mbit asynchronous low-power CMOS Static RAM organized as 256K x 16 bits. It operates over a wide voltage range of 2.7V to 5.5V and features a fast 55ns access time, making it suitable for high-speed buffering and temporary data storage. The 48-TFBGA package provides a compact footprint for space-constrained industrial and embedded designs.

Why Choose This Part

This SRAM offers high reliability with an industrial temperature range of -40 to +85 degrees Celsius and broad supply voltage compatibility. Its asynchronous architecture simplifies design by eliminating the need for a complex clock interface, while the 16-bit wide bus improves data throughput compared to 8-bit alternatives.

Applications

Industrial Controller Buffer
Provides reliable, fast-access temporary storage for PLC data and real-time processing variables.
Microcontroller Memory Expansion
Extends the RAM capacity of MCUs for applications requiring large look-up tables or data logging.
Battery-Backed Data Storage
Utilized in low-power systems requiring data retention via backup batteries due to its low standby current.

Getting Started

Integration requires a parallel memory interface on your MCU or FPGA, with address lines A0-A17 and data lines DQ0-DQ15. Ensure proper decoupling with 0.1uF capacitors near the VCC pins and verify timing requirements for the 55ns write cycle in your firmware or HDL code. No specialized drivers are needed as it acts as standard mapped memory.
