Product details
Overview
CY62148ELL-45ZSXA from Infineon Technologies (formerly Cypress) is a 4-Mbit (512K × 8) high-speed CMOS static RAM with 45 ns access time, 4.5–5.5 V supply range, and ultra-low standby current (2.5 µA typical). It features automatic CE-controlled power-down, TTL-compatible I/O, and is designed for battery-sensitive portable systems requiring fast, reliable non-volatile data buffering.
For engineers reviewing the CY62148ELL-45ZSXA datasheet, CY62148ELL-45ZSXA pinout, CY62148ELL-45ZSXA application, or CY62148ELL-45ZSXA equivalent, key selection criteria include industrial-grade 45 ns timing, TSOP II 32-pin package compatibility, MoBL® low-power architecture, and CE/OE/WE control logic for seamless microcontroller memory interfacing.
Technical Context
The CY62148ELL-45ZSXA implements a fully static 512K × 8 memory array with complementary metal oxide semiconductor (CMOS) process technology, enabling zero-refresh operation and deterministic read/write timing. Its dual-stage power management includes automatic CE-driven power-down and deep data retention mode at ≥2.0 V.
It supports three active control signals-Chip Enable (CE), Output Enable (OE), and Write Enable (WE)-with defined setup/hold and tri-state transition times (e.g., tHZOE ≤ 18 ns, tLZCE = 10 ns). Input thresholds comply with TTL logic levels (VIH ≥ 2.2 V, VIL ≤ 0.8 V), making it interoperable with legacy 5 V microcontrollers but not CMOS-level-only processors.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Size | 4 Mbit (512K words × 8 bits); provides byte-wide data bus interface without external demultiplexing |
| Access Time | 45 ns max; enables direct interfacing with 10–15 MHz microcontroller buses without wait states |
| VCC Range | 4.5 V to 5.5 V; supports standard 5 V rail with ±10% tolerance, compatible with legacy industrial power supplies |
| Standby Current | 7 µA max (industrial temp); reduces system quiescent power by >99% when CE is HIGH |
| Active Current | 6 mA max at f = fmax; limits dynamic power draw during burst reads/writes in portable applications |
| Data Retention Voltage | ≥2.0 V; allows memory state preservation during brown-out or battery-swapping events |
| Package | 32-pin TSOP II (ZSxA suffix); surface-mount footprint optimized for high-density PCB layouts |
Pinout & Package
Package: 32-pin Thin Small Outline Package (TSOP II), 12.1 mm × 20.0 mm body, 0.5 mm lead pitch, JEDEC MO-141AC compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A18 | Address Inputs | 19-bit address bus supporting full 512K-word decoding; A18 selects upper/lower half of memory space |
| I/O0–I/O7 | Bidirectional Data Bus | 8-bit parallel interface; enters high-Z when CE HIGH, OE HIGH, or WE LOW to prevent bus contention |
| CE | Chip Enable | Active-LOW global enable; forces automatic power-down and high-Z outputs when HIGH (CMOS level) |
| OE | Output Enable | Active-LOW read control; disables output drivers when HIGH, independent of CE state |
| WE | Write Enable | Active-LOW write control; initiates write cycle when CE and WE both LOW; latches data on rising edge |
| VCC | Power Supply | +4.5 V to +5.5 V core supply; decoupling capacitor required within 10 mm of pin per layout guidelines |
| VSS | Ground | Signal reference plane; must be connected to low-impedance ground plane to meet AC timing specs |
Key Features
| Feature | Design Value |
|---|---|
| MoBL® Ultra-Low Power Architecture | Reduces standby current to 2.5 µA typical-enables multi-week battery life in handheld medical monitors |
| Automatic CE-Controlled Power-Down | Eliminates need for external power-gating circuitry; cuts active-to-standby transition time to ≤45 ns |
| TTL-Compatible I/O Levels | Accepts VIH ≥ 2.2 V and VIL ≤ 0.8 V-interoperates directly with 8051, Z80, and legacy ARM7-based controllers |
| High-Speed 45 ns Access | Meets timing budgets for real-time data logging at 10+ MB/s sustained throughput in instrumentation systems |
| Industrial Temperature Range | –40 °C to +85 °C operation ensures reliability in automotive infotainment head units and factory HMIs |

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 512K × 8 organization, 45 ns speed, but uses 3.3 V only (2.7–3.6 V); lower ICC active (2.5 mA typ) | Requires level translation when interfacing with 5 V microcontrollers; unsuitable for legacy 5 V systems | Select if migrating to 3.3 V platform and redesigning power delivery; not drop-in compatible |
| Renesas R1LV5256ESBG-45SI | 5 V tolerant I/O, 45 ns access, but higher ISB (15 µA max); SOIC-only packaging (no TSOP II) | Larger SOIC footprint increases board area; higher standby current reduces battery life in portable use | Choose only when TSOP II is unavailable and SOIC mechanical fit is acceptable |
Compared with IS62WV5128BLL-45NLI and R1LV5256ESBG-45SI, CY62148ELL-45ZSXA uniquely delivers 5 V native operation, TSOP II density, and sub-3 µA standby in a single industrial-grade package-making it optimal for cost-sensitive, battery-powered 5 V embedded designs where board space and power budget are constrained.

FAQ
Is CY62148ELL-45ZSXA compatible with 3.3 V microcontrollers?
No. The device requires 4.5–5.5 V VCC and features TTL-compatible input thresholds (VIH ≥ 2.2 V, VIL ≤ 0.8 V), but its outputs do not guarantee 3.3 V logic-high levels. Interfacing with 3.3 V systems requires level-shifting circuitry or voltage translation ICs per Application Note AN6081.
What happens to data during power interruption below 2.0 V?
Data retention is guaranteed only down to VDR = 2.0 V. Below this voltage, memory contents are not preserved. The device supports data retention current (ICCDR) of 8.8 µA max at VDR, enabling backup from a coin cell or supercapacitor during brief brown-outs.
Does CY62148ELL-45ZSXA require an external clock signal?
No. As a static RAM, it operates asynchronously-timing depends solely on CE, OE, and WE control edges and address/data stability windows. No clock input or refresh circuitry is needed, simplifying design and reducing EMI sources.
Can I use the SOIC version (CY62148ELL-55ZXI) interchangeably with this TSOP II part?
No. The SOIC variant has 55 ns access time, different thermal resistance (θJA = 51.57 °C/W vs. 59.10 °C/W), and incompatible pin-to-pin mechanical layout. Electrical behavior differs under high-frequency operation, and PCB footprints are not interchangeable.
