Product details
Overview
CY7C1041GN30-10ZSXI from Infineon Technologies (formerly Cypress) is a 4-Mbit (256K × 16) asynchronous CMOS static RAM with 10 ns access time, 2.2–3.6 V supply operation, 38 mA typical active current, and 6 mA typical standby current. It supports byte-level write control via BHE/ BLE pins and operates across industrial temperature range (–40 °C to +85 °C) in a 44-pin TSOP II package - used in real-time data buffering for industrial PLCs, legacy telecom line cards, and FPGA configuration memory.
For engineers reviewing the CY7C1041GN30-10ZSXI datasheet, CY7C1041GN30-10ZSXI pinout, CY7C1041GN30-10ZSXI application, or CY7C1041GN30-10ZSXI equivalent, key selection criteria include verified 10 ns tAA timing at 3.0 V, dual-byte enable architecture, industrial-grade VCC tolerance (2.2–3.6 V), and compatibility with TTL-level I/O signaling in space-constrained board layouts.
Technical Context
This SRAM implements a fully decoded 18-bit address bus (A0–A17) driving a 256K-word × 16-bit memory array with independent high- and low-byte write enables (BHE/BLE). Read/write cycles are controlled by CE, OE, and WE with full TTL-compatible input thresholds and output drive strength.
It features automatic CE-controlled power-down (ISB2 = 6 mA typ) and retains data at 1.0 V VCC, enabling low-power suspend modes. The device supports three distinct VCC ranges - this variant is specified strictly for 2.2–3.6 V operation with guaranteed 10 ns access at fMAX = 100 MHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Organization | 256K words × 16 bits = 4 Mbit total storage; supports parallel 16-bit data bus interfacing without external multiplexing. |
| Access Time (tAA) | 10 ns max at VCC = 3.0 V, TA = 85 °C; enables direct interface with 100 MHz microcontrollers and FPGAs without wait states. |
| Supply Voltage Range | 2.2 V to 3.6 V only; not interoperable with 1.8 V or 5 V systems - requires dedicated LDO regulation in mixed-voltage designs. |
| Active Current (ICC) | 38 mA typical at VCC = 3.0 V, f = 100 MHz; defines thermal budget for continuous burst-mode operation in compact enclosures. |
| Standby Current (ISB2) | 6 mA typical when CE > VCC – 0.2 V and inputs held valid; enables low-power retention during processor sleep without external power gating. |
| Data Retention Voltage | 1.0 V minimum; allows system-level power sequencing where core logic shuts down before memory, preserving state during brownout. |
| I/O Compatibility | TTL-compatible inputs and outputs; eliminates level-shifter requirement when interfacing with legacy 3.3 V or 5 V controllers. |
Pinout & Package
Package: 44-pin Thin Small Outline Package Type II (TSOP II), JEDEC MO-141AC compliant, body size 12.0 mm × 20.0 mm × 1.2 mm, lead pitch 0.8 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| /CE | Chip Enable (active-low) | Primary device select; places all I/Os in high-impedance state when HIGH, enabling multi-SRAM bus sharing. |
| /OE | Output Enable (active-low) | Controls read-data output drivers only; allows CE-driven deselection while maintaining address/data bus integrity during partial reads. |
| /WE | Write Enable (active-low) | Initiates write cycle when CE and /WE both LOW; latches address and data on falling edge of /WE. |
| BHE | Byte High Enable | Enables write to I/O8–I/O15 only; permits 8-bit peripheral access to upper byte without disturbing lower byte contents. |
| BLE | Byte Low Enable | Enables write to I/O0–I/O7 only; supports mixed 8/16-bit data transfers in legacy ISA or CompactPCI subsystems. |
| A0–A17 | Address Inputs | 18-bit address bus decoding 256K locations; no internal address latching - requires stable address during entire CE-active window. |
| I/O0–I/O15 | Bi-directional Data Bus | 16-bit bidirectional CMOS/TTL-compatible data path; transitions to high-Z within tHZCE (10 ns max) after /CE goes HIGH. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-byte write control | Independent BHE/BLE pins allow atomic 8-bit writes to upper or lower half of 16-bit word - critical for MISRA-compliant firmware updates in safety-critical PLCs. |
| 10 ns access at 3.0 V | Guaranteed tAA ≤ 10 ns across full industrial temperature range, enabling deterministic timing closure in real-time motion control loops. |
| 1.0 V data retention | Preserves stored configuration or fault logs during main power loss, supporting fail-safe restart without external backup capacitors. |
| Low ISB2 standby current | 6 mA typical at VCC = 3.0 V ensures <15 mW standby power in always-on industrial gateways - meets EN 50178 leakage limits. |
| TTL-compatible I/O | Eliminates need for voltage translators when interfacing with legacy 3.3 V or 5 V microcontrollers (e.g., TI C2000, NXP S32K), reducing BOM count. |

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 | 4-Mbit (512K × 8), 10 ns, 2.7–3.6 V only; no BHE/BLE; SOJ-32 package | Requires external byte-width adaptation for 16-bit buses; lacks industrial temp support (0–70 °C only) | Select only if 8-bit bus architecture is fixed and ambient temperature stays below 70 °C. |
| IS61LV25616AL-10TLI | 4-Mbit (256K × 16), 10 ns, 3.3 V ±10%; ISB = 1 µA (vs. 6 mA); 44-pin TSOP II | Ultra-low standby power enables battery-backed operation; tighter VCC tolerance restricts use with wide-input DC/DCs | Prefer for portable or energy-harvesting systems where ISB < 10 µA is mandatory and 3.0–3.6 V rail is regulated. |
Compared with AS6C4008-10TIN and IS61LV25616AL-10TLI, CY7C1041GN30-10ZSXI uniquely supports 2.2–3.6 V operation with byte-enable flexibility and industrial temperature rating - making it the only choice for ruggedized 16-bit bus systems requiring wide-input voltage tolerance and deterministic timing across –40 °C to +85 °C.

FAQ
Is CY7C1041GN30-10ZSXI pin-compatible with CY7C1041GN30-10ZSI?
Yes - both share identical 44-pin TSOP II footprint and pinout. The 'X' suffix denotes extended temperature grade (–40 °C to +85 °C), while 'S' indicates standard industrial grade (0 °C to +70 °C); electrical specs and timing are identical within their respective operating ranges.
Can CY7C1041GN30-10ZSXI operate at 1.8 V?
No - this variant is rated exclusively for 2.2 V to 3.6 V operation. Attempting 1.8 V operation violates absolute maximum ratings and results in undefined behavior, including data corruption and increased ICC. Use CY7C1041GN18-15ZSXI for 1.65–2.2 V applications.
What is the maximum clock frequency supported for burst reads?
This is an asynchronous SRAM - it has no internal clock. Maximum effective throughput depends on external controller timing: with 10 ns tAA and 10 ns tOH, sustained 100 MHz bus cycles are achievable when CE/OE/WE setup/hold times are met, yielding up to 160 MB/s peak bandwidth on a 16-bit bus.
Does CY7C1041GN30-10ZSXI support battery backup mode?
Yes - its 1.0 V data retention capability allows connection to a coin-cell or supercapacitor via diode-OR circuit. When main VCC drops below 2.2 V, the device automatically enters retention mode with ISB2 ≤ 8 mA, preserving data for >1 year at room temperature with 10 µF hold-up capacitance.
