Product details
Overview
CY62148GN-45SXI 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 extended battery life.
For engineers reviewing the CY62148GN-45SXI datasheet, CY62148GN-45SXI pinout, CY62148GN-45SXI application, or CY62148GN-45SXI equivalent, key selection criteria include verified 45 ns read/write timing, dual-voltage compatibility, TSOP II/SOIC package footprint, MoBL® low-power architecture, and industrial-grade temperature support (–40 °C to +85 °C).
Technical Context
The CY62148GN-45SXI implements a full CMOS 512K × 8 asynchronous SRAM 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.
It supports three distinct operational modes: active read (CE=LOW, OE=LOW, WE=HIGH), active write (CE=LOW, WE=LOW), and standby (CE=HIGH). Output enable (OE) and write enable (WE) are fully independent, enabling flexible bus sharing and partial write masking via address gating.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Size | 4 Mbit (512K words × 8 bits); supports byte-wide data bus interfacing without multiplexing or external latching. |
| Access Time | 45 ns max; guarantees deterministic read latency under worst-case voltage/temperature conditions for real-time control loops. |
| VCC Range | 2.2–3.6 V or 4.5–5.5 V; enables direct integration into both modern low-voltage microcontroller systems and legacy 5 V logic domains. |
| Standby Current | 8.7 µA max at VCC(max); reduces system quiescent power by >99% versus active mode, critical for battery-backed operation. |
| Operating Temperature | –40 °C to +85 °C; qualified for industrial embedded environments including programmable logic controllers and remote I/O modules. |
| Package Type | 32-pin TSOP II (thin small outline package); surface-mount compatible with standard reflow profiles and high-density PCB layouts. |
| Data Retention Voltage | 1.0 V min (VDR); maintains stored data during brown-out or backup-battery operation without refresh. |
Pinout & Package
Package: 32-pin Thin Small Outline Package (TSOP II), 0.4 mm pitch, 10.16 mm × 18.4 mm body size, JEDEC MO-141AC compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A18 | Address Inputs | 19-bit address bus supporting full 512K-word addressing; no internal address multiplexing required. |
| I/O0–I/O7 | Bidirectional Data Bus | 8-bit tri-state data interface; high-impedance during CE HIGH, OE HIGH, or WE LOW to prevent bus contention. |
| CE | Chip Enable | Active-LOW global device select; HIGH forces automatic power-down and output high-Z regardless of OE/WE state. |
| OE | Output Enable | Active-LOW read control; independent of WE, allowing simultaneous read/write arbitration on shared buses. |
| WE | Write Enable | Active-LOW write strobe; initiates write cycle when CE is LOW; does not affect outputs when CE is HIGH. |
| VCC | Power Supply | Single-supply input supporting dual voltage ranges; decoupling capacitor placement critical for 45 ns timing stability. |
| VSS | Ground | Dedicated ground pin; must be connected to low-impedance PCB plane to minimize switching noise on I/O and address lines. |
Key Features
| Feature | Design Value |
|---|---|
| MoBL® Ultra-Low Power Architecture | Reduces standby current to ≤8.7 µA while maintaining full SRAM functionality-enables multi-year battery life in portable instrumentation. |
| Automatic CE-Controlled Power-Down | Eliminates need for external power management logic; transitions to <10 µA state within 45 ns of CE deassertion. |
| Dual-Voltage Operation | Supports seamless migration between 2.5 V/3.3 V and 5 V systems without level-shifting circuitry or redesign. |
| Asynchronous Interface Timing | Guaranteed 45 ns tRC, tAA, and tWC with no clock or wait-state generation required-simplifies interface to FPGA, MCU, and ASIC hosts. |
| Industrial Temperature Qualification | Validated across –40 °C to +85 °C with full AC/DC parametric compliance-suitable for uncontrolled environmental deployments. |

FAQ
Does CY62148GN-45SXI require an external clock or refresh circuit?
No. The CY62148GN-45SXI is a fully asynchronous static RAM with no clock input or refresh requirement. Data retention is indefinite as long as VCC remains within specification and CE is held HIGH in standby mode. Its CMOS latch-based cell design eliminates periodic refresh overhead entirely.
Can CY62148GN-45SXI operate reliably at 2.5 V and 85 °C simultaneously?
Yes. The device is fully specified and tested across its entire industrial temperature range (–40 °C to +85 °C) at both 2.2–3.6 V and 4.5–5.5 V VCC ranges. At 2.5 V and +85 °C, all AC parameters-including 45 ns tRC and tWC-remain within guaranteed limits per datasheet Rev. *D.
What is the maximum capacitive load the I/O pins can drive while maintaining 45 ns timing?
The CY62148GN-45SXI is characterized for 30 pF total load (including board trace and scope probe capacitance) at 1 V/ns edge rate. Driving loads >30 pF may increase tAA and tDOE beyond 45 ns; for heavier loads, use series termination or buffer drivers to maintain timing compliance.
Is the TSOP II package of CY62148GN-45SXI RoHS and REACH compliant?
Yes. The CY62148GN-45SXI is manufactured in a Pb-free (RoHS-compliant) process and meets EU REACH SVHC requirements. The "S" suffix in the part number explicitly denotes lead-free finish, and full compliance documentation is available through Infineon's product change notifications (PCNs).
