Product details
Overview
CY7C1041GN30-10VXI from Infineon Technologies (formerly Cypress) is a 4-Mbit (256K × 16) asynchronous CMOS static RAM with 10 ns access time, operating across 2.2 V–3.6 V supply range, TTL-compatible I/Os, and low-power standby current of 6 mA typical-designed for high-speed buffer and cache memory in industrial microcontroller systems.
For engineers reviewing the CY7C1041GN30-10VXI datasheet, CY7C1041GN30-10VXI pinout, CY7C1041GN30-10VXI application, or CY7C1041GN30-10VXI equivalent, key selection criteria include verified 10 ns tAA timing at 3.0 V, dual-byte write enable (BHE/ BLE), 48-ball VFBGA (BVXI) package mapping, and data retention at 1.0 V.
Technical Context
This SRAM implements a fully decoded 18-bit address space (A0–A17), supporting independent upper- and lower-byte writes via BHE and BLE control signals. All I/Os enter high-impedance state when CE is HIGH or OE/BLE/BHE are deasserted-enabling clean bus sharing without external isolation.
It operates across three voltage ranges but CY7C1041GN30 specifically targets 2.2 V–3.6 V, where ICC = 38 mA typical at fMAX, ISB2 = 6 mA typical in automatic CE power-down mode, and supports 1.0 V data retention with tCDR = 0 ns and tR = 10 ns (VCC > 2.2 V).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory size | 4 Mbit (256K words × 16 bits) - provides 512 KB of parallel-access storage for real-time data buffering |
| Access time (tAA) | 10 ns at VCC = 3.0 V - enables direct interfacing with 100 MHz microcontrollers without wait states |
| Supply voltage range | 2.2 V to 3.6 V - compatible with modern low-voltage logic families and battery-backed industrial systems |
| Active current (ICC) | 38 mA typical at fMAX - supports burst-mode operation in embedded controllers with thermal margin |
| Standby current (ISB2) | 6 mA typical - ensures low quiescent power during sleep modes in always-on edge devices |
| Data retention voltage | 1.0 V - maintains stored contents during brown-out or backup-battery operation |
| Input/output compatibility | TTL-compatible - eliminates level-shifting requirements when interfacing with legacy MCU buses |
Pinout & Package
Package: 48-ball Very Thin Fine-Pitch Ball Grid Array (VFBGA), 6 mm × 8 mm × 1.0 mm, JEDEC MO-276AC (Package ID: BVXI). Pinout validated per Figure 1, Document 001-95413 Rev. *D, Page 4.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A17 | Address inputs | 18-bit address bus supporting full 256K-word decoding without external latching |
| I/O0–I/O7 | Lower data byte | Driven or read under BLE = LOW; isolated when BLE = HIGH or CE = HIGH |
| I/O8–I/O15 | Upper data byte | Driven or read under BHE = LOW; isolated when BHE = HIGH or CE = HIGH |
| CE | Chip Enable | Active-LOW global device select; forces all I/Os into high-Z when HIGH |
| OE | Output Enable | Active-LOW read strobe; controls output drivers independently of CE and WE |
| WE | Write Enable | Active-LOW write strobe; initiates write cycle when CE and WE both LOW |
| BHE / BLE | Byte High/Low Enable | Independent active-LOW controls for upper/lower byte writes-enables 8-bit subsystem integration |
Key Features
| Feature | Design Value |
|---|---|
| Dual-byte write control | Separate BHE and BLE pins allow selective 8-bit writes without masking or extra logic |
| Multi-voltage support | Validated operation across 2.2 V–3.6 V enables drop-in use in mixed-supply industrial PCBs |
| Low-power data retention | Maintains valid data at 1.0 V with no clock or refresh-critical for battery-backed memory holdover |
| High-impedance I/O control | I/Os automatically tri-state on CE HIGH or OE/BLE deassertion-eliminates need for external bus buffers |
| Pb-free packaging | RoHS-compliant 48-ball VFBGA meets IPC/JEDEC standards for automated SMT assembly |

Equivalent & Alternatives
The following parts are listed as comparable options for similar asynchronous SRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IS61LV25616AL-10TLI | 10 ns access, 3.3 V only, 44-pin TSOP II package, no BHE/ BLE - uses single WE for full 16-bit writes | Lacks byte-write granularity; requires external gating for 8-bit subsystems | Select when board layout prioritizes TSOP II footprint and byte-level control is unnecessary |
| AS6C4008-10TIN | 10 ns access, 2.7–3.6 V, 44-pin TSOP II, TTL-compatible, but no 1.0 V data retention | Higher ISB2 (12 mA typical); no guaranteed data hold below 2.2 V | Prefer for cost-sensitive consumer applications where battery backup is not required |
Compared with IS61LV25616AL-10TLI and AS6C4008-10TIN, CY7C1041GN30-10VXI uniquely delivers byte-select write capability, 1.0 V data retention, and VFBGA packaging-making it optimal for space-constrained, battery-resilient industrial designs requiring flexible memory access.

FAQ
Is CY7C1041GN30-10VXI pin-compatible with CY7C1041GN18-15VXI?
No. While both share identical 48-ball VFBGA (BVXI) mechanical footprint, CY7C1041GN18 operates at 1.65–2.2 V with 15 ns tAA and different DC/AC characteristics. Voltage range mismatch and timing divergence prevent direct substitution without system-level validation.
Does CY7C1041GN30-10VXI support true 8-bit interface mode?
Yes. With BLE = LOW and BHE = HIGH, only I/O0–I/O7 are driven or read; with BHE = LOW and BLE = HIGH, only I/O8–I/O15 are active. Both byte lanes operate independently under CE and OE control-enabling native 8-bit peripheral interfacing without glue logic.
What is the maximum junction temperature for continuous operation?
The device is rated for –40 °C to +85 °C ambient temperature. Using θJA = 31.35 °C/W (VFBGA), maximum allowable power dissipation at 85 °C ambient is 1.56 W. At 38 mA ICC and 3.3 V, typical power is 125 mW-well within thermal limits for standard PCB layouts.
Can CY7C1041GN30-10VXI retain data during complete VCC removal?
No. Data retention requires VCC ≥ 1.0 V. If VCC drops below 1.0 V, data is not guaranteed. The device supports retention down to 1.0 V-not zero volts-so a backup capacitor or coin cell must maintain ≥1.0 V during main supply interruption.
