Product details
Overview
CY62148GN-45ZSXI from Infineon Technologies (formerly Cypress) is a 4-Mbit (512K × 8) CMOS static RAM with 45 ns access time, operating across dual voltage ranges (2.2–3.6 V and 4.5–5.5 V), ultra-low standby current (3.5 µA typical), and automatic CE-controlled power-down. It serves as main or buffer memory in portable industrial controllers requiring deterministic timing and battery longevity.
For engineers reviewing the CY62148GN-45ZSXI datasheet, CY62148GN-45ZSXI pinout, CY62148GN-45ZSXI application, or CY62148GN-45ZSXI equivalent, key selection criteria include guaranteed 45 ns read/write cycle timing, dual-voltage compatibility, TSOP II package footprint, MoBL® low-power architecture, and industrial temperature support (–40 °C to +85 °C).
Technical Context
This SRAM implements a full CMOS 512K × 8 array with independent address decoding, sense amplifiers, and input/output buffers. Its automatic power-down logic activates when CE is HIGH and address lines are stable, reducing ICC to ≤8.7 µA without external control.
The device supports three distinct operational modes: active read (CE/OE LOW, WE HIGH), active write (CE/WE LOW), and standby (CE HIGH). I/O pins enter high-impedance state during deselection, OE HIGH, or write cycles-enabling seamless bus sharing in multi-chip systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Size | 4 Mbit (512K × 8) - provides byte-wide data interface with 19-bit address space (A0–A18) |
| Access Time | 45 ns - guarantees worst-case read latency under full industrial voltage/temperature conditions |
| VCC Range | 2.2–3.6 V or 4.5–5.5 V - supports both modern low-voltage microcontrollers and legacy 5 V systems |
| Standby Current | 3.5 µA typical / 8.7 µA max - enables >1-year battery life in always-on sensor nodes at 3 V |
| Operating Temperature | –40 °C to +85 °C - qualified for industrial control, metering, and automotive body electronics |
| Package | 32-pin TSOP II (ZS suffix) - 12.1 mm × 20.0 mm footprint compatible with automated SMT assembly |
| Data Retention Voltage | 1.0 V minimum - maintains stored data during brown-out or backup-battery operation |
Pinout & Package
Package: 32-pin Thin Small Outline Package (TSOP II), RoHS-compliant, lead-free, JEDEC MO-141AC standard.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A18 | Address Inputs | 19-bit address bus accepting 0x00000–0x7FFFF; no internal latching - requires stable address before CE activation |
| I/O0–I/O7 | Bidirectional Data Bus | CMOS-compatible 8-bit data path; high-impedance when CE HIGH, OE HIGH, or WE LOW |
| CE | Chip Enable | Active-LOW enable; drives automatic power-down when HIGH and address stable - primary power-gating control |
| OE | Output Enable | Active-LOW read control; disables outputs (high-Z) when HIGH - isolates data bus during writes or idle |
| WE | Write Enable | Active-LOW write strobe; initiates write on falling edge with CE LOW - defines write cycle boundaries |
| VCC | Power Supply | Single-supply input supporting two voltage domains; decoupling capacitor required per JEDEC guidelines |
| VSS | Ground | Digital ground reference; must be connected to system GND plane with low-inductance path |
Key Features
| Feature | Design Value |
|---|---|
| MoBL® Ultra-Low Standby Power | Reduces system quiescent current by >99% vs. standard SRAMs - critical for coin-cell-powered devices |
| Automatic CE Power-Down | Eliminates need for external power-management logic - transitions to <8.7 µA ISB2 with no software or timing overhead |
| Dual-Voltage Operation | Single part replaces two SKUs - interoperable with 3.3 V MCUs and 5 V peripherals without level shifters |
| High-Reliability CMOS Process | Qualified to AEC-Q100 stress tests - supports 10-year data retention at 85 °C in industrial deployments |
| Bus-Friendly Tri-State Control | Independent OE/CE/WE enables clean bus arbitration in multi-master systems - no bus contention during mode transitions |

Equivalent & Alternatives
The following parts are listed as comparable options for similar SRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ISSI IS62WV5128BLL-45NLI | Same density and speed; 2.7–3.6 V only; 10 µA max ISB; SOIC-32 only | Lacks 4.5–5.5 V support and TSOP II option - unsuitable for mixed-voltage systems | Select if design uses only 3.3 V and prioritizes second-source availability over package flexibility |
| Renesas R1LV5128ASBG-45SI | 45 ns, 2.2–3.6 V, 12 µA max ISB; supports 1.8 V data retention; TSOP II available | Higher standby current reduces battery life in long-idle applications; tighter VDR enables deeper sleep | Choose when 1.8 V data retention is mandatory and 3.5 µA ISB is not required |
Compared with IS62WV5128BLL-45NLI and R1LV5128ASBG-45SI, CY62148GN-45ZSXI uniquely delivers dual-voltage operation, lowest verified standby current (3.5 µA typ), and industrial-grade TSOP II packaging - making it optimal for battery-constrained, mixed-rail embedded systems.

FAQ
What is the maximum clock frequency supported by CY62148GN-45ZSXI?
CY62148GN-45ZSXI is an asynchronous SRAM and does not use a clock signal. Its performance is defined by access time (45 ns) and cycle time (45 ns), enabling reliable operation up to approximately 22 MHz random read/write throughput when interfaced with microcontrollers or FPGAs using proper timing margins.
Can CY62148GN-45ZSXI operate at 3.0 V and still meet the 45 ns specification?
Yes. The 45 ns access time is fully specified and tested across the entire 2.2–3.6 V range, including 3.0 V. Electrical characteristics tables confirm tAA, tRC, and tWC all maintain 45 ns max at VCC = 3.0 V and TA = 85 °C - no derating required.
Is the TSOP II package (ZS) pin-compatible with the SOIC package (Z)
Yes. Both the CY62148GN-45ZSXI (TSOP II) and CY62148GN-45ZXI (SOIC) share identical 32-pin numbering, signal mapping, and logic behavior. The ZS and ZX variants differ only in mechanical form factor - allowing drop-in replacement during layout revision or cost optimization.
Does CY62148GN-45ZSXI require external refresh circuitry?
No. As a static RAM, CY62148GN-45ZSXI retains data indefinitely while powered and does not require refresh cycles. Data retention continues down to 1.0 V VCC (ICCDR ≤13 µA), eliminating refresh logic, timers, or associated firmware overhead.
