Infineon Technologies CY7C1041GN30-10BVJXIT

Overview

CY7C1041GN30-10BVJXIT from Infineon Technologies (formerly Cypress) is a 4-Mbit (256K × 16) asynchronous CMOS static RAM with 10 ns access time, 2.2 V–3.6 V supply range, 38 mA typical active current, and 6 mA typical standby current. It supports byte-wide writes via BHE/ BLE control and operates in industrial temperature range (–40 °C to +85 °C) in a 48-ball VFBGA package. It serves as fast on-board data buffer in real-time industrial controllers.

For engineers reviewing the CY7C1041GN30-10BVJXIT datasheet, CY7C1041GN30-10BVJXIT pinout, CY7C1041GN30-10BVJXIT application, or CY7C1041GN30-10BVJXIT equivalent, key selection criteria include VCC compatibility across 2.2–3.6 V, 10 ns tAA timing under industrial conditions, byte-select capability for partial-word writes, and VFBGA thermal resistance (θJA = 31.35 °C/W) for high-density PCB layouts.

Technical Context

This SRAM implements a fully decoded 18-bit address space (A0–A17), supporting 256K word × 16-bit organization with independent high-byte (I/O8–I/O15, controlled by BHE) and low-byte (I/O0–I/O7, controlled by BLE) write enable. Read and write cycles are initiated by CE-low with OE-low (read) or WE-low (write), all TTL-compatible at 3.0 V VCC.

It features dual power-down modes: ISB1 (15 mA, TTL input threshold) and ISB2 (6 mA, CMOS input threshold), triggered by CE-high while maintaining data retention down to 1.0 V. Data retention current ICCDR is specified ≤8 mA at VCC = 1.2 V, with tCDR = 0 ns and recovery time tR = 10 ns above 2.2 V.

FAQ

Is CY7C1041GN30-10BVJXIT pin-compatible with other CY7C1041GN variants?

Yes - all CY7C1041GN variants share identical 48-ball VFBGA pinout (BVJX footprint), including CY7C1041GN18 and CY7C1041GN. The only differences are speed grade (10 ns vs. 15 ns) and VCC range (2.2–3.6 V for GN30 vs. 1.65–2.2 V for GN18). No PCB redesign is needed when upgrading within the same package variant.

What is the maximum operating frequency supported by CY7C1041GN30-10BVJXIT?

The device does not have a clock input and is asynchronous; its maximum usable frequency depends on system timing margins. With tAA = 10 ns and tOH = 5 ns, it supports reliable 100 MHz burst reads/writes when interfaced with microcontrollers or FPGAs meeting setup/hold timing constraints per the datasheet AC switching characteristics table.

Does CY7C1041GN30-10BVJXIT require external decoupling capacitors?

Yes - the datasheet specifies two 0.1 µF ceramic capacitors: one between each VCC pin (Balls A5 and D5) and nearest VSS (Balls C6 and E5), placed within 3 mm of respective balls. This dual-decoupling scheme is mandatory to maintain signal integrity and meet ISB2 current spec under fast switching conditions.

Can CY7C1041GN30-10BVJXIT operate at 2.5 V with guaranteed 10 ns access time?

Yes - the 10 ns tAA specification is guaranteed over the full 2.2 V–3.6 V range, including 2.5 V. Electrical characteristics tables confirm VOH ≥ 2.2 V and VOL ≤ 0.4 V at VCC = 2.5 V, ensuring robust TTL/CMOS compatibility without level shifters in mixed-signal 2.5 V systems.
