Product details
Overview
CY7C1049GN30-10ZSXIT from Infineon Technologies (formerly Cypress) is a 4-Mbit (512K × 8) asynchronous CMOS static RAM with 10 ns access time, TTL-compatible I/Os, and dual-voltage operation (2.2 V–3.6 V). It delivers 38 mA typical active current and 6 mA typical standby current, supporting industrial temperature range (–40 °C to +85 °C) in a 44-pin TSOP II package for embedded memory buffering in microcontroller-based systems.
For engineers reviewing the CY7C1049GN30-10ZSXIT datasheet, CY7C1049GN30-10ZSXIT pinout, CY7C1049GN30-10ZSXIT application, or CY7C1049GN30-10ZSXIT equivalent, key selection criteria include tAA = 10 ns timing, VCC = 2.2–3.6 V compliance, ISB2 = 6 mA low-power standby mode, and 44-pin TSOP II mechanical compatibility with legacy SRAM footprints.
Technical Context
This SRAM implements a full asynchronous interface with independent Chip Enable (CE), Output Enable (OE), and Write Enable (WE) controls. Address decoding uses a hierarchical row/column architecture across A0–A18 (19-bit address bus), supporting 512K-word addressing without internal refresh circuitry.
All eight bidirectional data lines (I/O0–I/O7) enter high-impedance state when CE is HIGH or OE is deasserted. Data retention at 1.0 V enables ultra-low-power hold mode during system sleep, verified down to –40 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Size | 4 Mbit (512K words × 8 bits) - supports byte-wide data transfers without external multiplexing |
| Access Time (tAA) | 10 ns - enables direct interfacing with 80–100 MHz microcontrollers without wait states |
| VCC Operating Range | 2.2 V to 3.6 V - compatible with 3.3 V logic domains and mixed-voltage system partitioning |
| Active Current (ICC) | 38 mA typical - limits thermal load in dense PCB layouts with multiple memory devices |
| Standby Current (ISB2) | 6 mA typical - sustains low-power operation during CPU idle cycles in battery-backed systems |
| Data Retention Voltage | 1.0 V - allows memory contents to persist during brown-out conditions or controlled power-down sequences |
| Temperature Range | –40 °C to +85 °C - qualified for industrial-grade reliability in motor control and PLC applications |
Pinout & Package
44-pin Thin Small Outline Package (TSOP II), 400 mil width, lead-free, surface-mount. Pin pitch: 0.8 mm. Body dimensions: 18.4 mm × 10.16 mm × 1.2 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A18 | Address Inputs | 19-bit unidirectional address bus; fully decoded to select one of 524,288 memory locations |
| I/O0–I/O7 | Bidirectional Data Lines | 8-bit parallel data path; tri-stated automatically when CE HIGH or OE deasserted |
| CE | Chip Enable | Active-low device select; enables internal logic and memory array only when LOW |
| OE | Output Enable | Active-low read control; gates output drivers but does not disable write path |
| WE | Write Enable | Active-low write strobe; latches data on I/O0–I/O7 into selected memory location |
| VCC | Power Supply | Primary supply pin; two VCC pins (pins 11 & 34) reduce IR drop and improve noise immunity |
| VSS | Ground | Two dedicated ground pins (pins 12 & 33) provide low-inductance return paths for I/O and core logic |
| NC | No Connect | Pins 1, 4, 5, 21–24, 43 - internally unconnected; must remain floating or tied to GND per layout guidelines |
Key Features
| Feature | Design Value |
|---|---|
| 10 ns access time | Enables zero-wait-state operation with ARM Cortex-M4/M7 and RISC-V MCUs running at ≤100 MHz |
| 6 mA ISB2 standby current | Reduces system-level quiescent power by >40% versus comparable 5 V SRAMs in always-on monitoring nodes |
| 1.0 V data retention | Permits memory hold during deep-sleep modes without auxiliary backup power circuitry |
| TTL-compatible I/O levels | Eliminates level-shifting requirements when interfacing with legacy 3.3 V or 5 V peripheral controllers |
| Industrial temperature grade | Validated for continuous operation in motor drives, HVAC controllers, and factory automation hardware |

Equivalent & Alternatives
The following parts are listed as comparable options for similar asynchronous SRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AS6C4008-10TIN | 10 ns access, 4-Mbit (512K × 8), VCC = 2.7–3.6 V only; no 2.2 V support | Lacks 2.2 V operation - unsuitable for low-voltage brown-out tolerance designs | Select if system operates strictly at 3.3 V and requires lower ISB2 (2 μA vs. 6 mA) |
| IS61LV5128AL-10TLI | 10 ns access, same density and pinout; VCC = 3.0–3.6 V; ISB2 = 1 μA typical | Higher minimum VCC excludes use in 2.5 V domains; superior standby efficiency | Prefer for battery-powered portable instruments needing <1 μA standby current |
Compared with AS6C4008-10TIN and IS61LV5128AL-10TLI, CY7C1049GN30-10ZSXIT uniquely supports 2.2 V operation and delivers guaranteed 10 ns timing across its full voltage range-critical for automotive and industrial systems requiring robustness across wide input voltage transients.

FAQ
Is CY7C1049GN30-10ZSXIT pin-compatible with CY7C1049DV33-10ZSXI?
No. CY7C1049GN30-10ZSXIT uses a 44-pin TSOP II package with single CE, while CY7C1049DV33-10ZSXI is a 48-pin TSOPII with dual CE (/CE1 and /CE2) and different pin assignments for A15–A18 and I/O lines. Mechanical and signal mapping are incompatible.
Does this SRAM require an external clock or refresh controller?
No. CY7C1049GN30-10ZSXIT is a fully asynchronous static RAM with no clock input. It performs reads and writes solely on edge-triggered CE, OE, and WE signals. No refresh circuitry or periodic access is needed-data remains valid as long as VCC and CE conditions are met.
Can it operate reliably at 2.2 V with 10 ns access time across the full temperature range?
Yes. The datasheet specifies tAA = 10 ns maximum over –40 °C to +85 °C at VCC = 2.2 V to 3.6 V. This is a guaranteed limit-not a typical value-and applies to all units in the industrial grade binning.
What is the maximum sustained write cycle rate supported?
With tAA = 10 ns and minimum write pulse widths (tWP = 10 ns, tCW = 10 ns), the device supports up to 50 million write cycles per second under ideal signal integrity conditions. Real-world throughput is limited by bus turnaround time and controller timing margins, typically achieving 40–45 MHz sustained burst writes.
