Description

Product Overview

The CY7C1041GN30-10ZSXIT from Infineon Technologies (formerly Cypress Semiconductor) is a 4-Mbit (256K × 16-bit) asynchronous static RAM in a 44-pin TSOP II package, offering 10 ns access time. It operates from a 2.2 V to 3.6 V supply with 38 mA typical active current and 6 mA typical standby current, featuring byte-enable control and 1.0 V data retention.

  • Digital signal processing
  • Industrial control systems
  • Data acquisition and buffering

The Infineon CY7C1041GN30-10ZSXIT is a high-performance CMOS static RAM organized as 256K words by 16 bits, providing 4 Mbit of fast asynchronous memory with 10 ns access time. It operates from a 2.2 V to 3.6 V supply and features independent byte enable inputs (BHE and BLE) for flexible upper and lower byte access. The device supports 1.0 V data retention for battery-backed operation. With TTL-compatible I/O, low 38 mA active current, and a compact 44-pin TSOP II package, it is ideal for high-speed buffering in networking, DSP, and embedded processor applications.

The CY7C1041GN operates as an asynchronous static RAM requiring no clock or refresh. Data writes are performed by asserting Chip Enable (CE) and Write Enable (WE) low while presenting data on I/O0-I/O15 and address on A0-A17. Byte High Enable (BHE) and Byte Low Enable (BLE) control write access to the upper (I/O8-I/O15) and lower (I/O0-I/O7) bytes independently. Data reads are performed by asserting CE and Output Enable (OE) low, placing the addressed data on the I/O lines. When CE is high or control signals are de-asserted, all I/Os enter a high-impedance state. The device maintains data as long as VCC is above the data retention voltage of 1.0 V.
