Overview

The CY62147GE30-45ZSXI is a 4-Mbit asynchronous SRAM organized as 256K words by 16 bits. It operates within a voltage range of 2.2V to 3.6V and features an integrated Error Correcting Code (ECC) engine to enhance data reliability. This MoBL (More Battery Life) series device is optimized for low-power applications, drawing only 8.7 uA in standby mode.

Why Choose This Part

The primary advantage is the on-chip ECC, which provides hardware-level single-bit error correction to improve system reliability. It offers a fast 45 ns access time while maintaining a low typical operating current of 15mA, making it suitable for high-performance yet power-constrained designs.

Applications

Industrial Control Systems
Used as reliable buffer memory for PLC and automation controllers that require fast, deterministic access without the overhead of a refresh cycle.
Battery-Powered Handhelds
Ideal for portable instruments and handheld terminals where the ultra-low standby current extends battery life.
Embedded Telemetry Units
Provides a non-volatile-like experience when paired with a small backup battery for critical data logging in remote environments.

Getting Started

To integrate this device, interface the 16-bit parallel data bus and address lines to your MCU's external memory interface (EMIF) or FSMC. Ensure proper decoupling with capacitors placed close to the VDD pins of the 44-pin TSOP II package to maintain signal integrity during high-speed switching.

Also Consider
