Overview

The AS6C8016B-45BIN is an 8Mbit asynchronous CMOS static RAM organized as 512K x 16 bits. It operates from a wide supply range of 2.7V to 3.6V and is designed for applications requiring high-speed data access with low power consumption. The device is fully static, requiring no clock or refresh cycles, and features a battery backup mode with data retention down to 1.5V.

Why Choose This Part

This SRAM offers a fast 45ns access time while maintaining a low typical operating current of 12mA. Its 48-TFBGA package saves significant PCB space compared to TSOP alternatives, and its TTL-compatible inputs/outputs simplify interfacing with standard 3.3V logic. The device also includes data byte control (LB and UB pins) for flexible 8-bit or 16-bit word access.

Applications

Buffer Memory for Embedded Systems
Provides high-speed temporary storage for microcontrollers and DSPs during data processing tasks.
Industrial Control Systems
Used in PLC and HMI applications where reliable operation across an industrial temperature range of -40C to 85C is required.
Battery-Powered Handheld Devices
Ideal for portable equipment due to its very low 2.5uA typical standby current and low-voltage data retention capability.
Networking and Communication Hardware
Functions as a fast lookup table or packet buffer in communication modules using parallel memory interfaces.

Getting Started

To interface this SRAM, connect the address and data lines to your MCU external memory interface (EMI) or FSMC bus, ensuring proper pull-up resistors on control lines like CE, OE, and WE. For initial prototyping, use a BGA-to-DIP adapter or a custom breakout board since the 48-TFBGA package is not breadboard-friendly. Verify that your software wait-states are configured to meet the 45ns timing requirements at your specific operating voltage.
