Product details
Overview
CY62148EV30LL-55SXIT from Infineon Technologies (formerly Cypress) is a 4-Mbit (512K × 8) CMOS static RAM with 45 ns access time, 2.2–3.6 V supply range, and industrial/automotive-A temperature rating (–40 °C to +85 °C). It delivers ultra-low standby current (7 µA max), active current of 3.5 mA at 1 MHz, and automatic CE-controlled power-down-enabling battery-critical MoBL® applications such as portable medical monitors and automotive telematics modules.
For engineers reviewing the CY62148EV30LL-55SXIT datasheet, CY62148EV30LL-55SXIT pinout, CY62148EV30LL-55SXIT application, or CY62148EV30LL-55SXIT equivalent, key selection criteria include VFBGA-36 package compatibility, 512K × 8 organization, 45 ns read cycle time, CE/OE/WE control logic timing, and data retention down to 1.5 V.
Technical Context
This SRAM implements a fully decoded 512K × 8 array with complementary metal oxide semiconductor (CMOS) architecture optimized for speed-power trade-off in portable systems. Its automatic power-down activates when CE is HIGH, reducing ICC to ≤7 µA while placing I/Os in high-impedance state-critical for intermittent-data logging in low-duty-cycle IoT edge nodes.
The device supports three standard memory control protocols: read (CE & OE LOW, WE HIGH), write (CE & WE LOW), and standby (CE HIGH). Timing parameters-including tRC = 45 ns, tDOE = 22 ns, and tHZOE = 18 ns-are guaranteed across full voltage (2.2–3.6 V) and temperature (–40 °C to +85 °C) ranges, ensuring deterministic behavior in safety-relevant automotive subsystems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Size | 4 Mbit (512K × 8) - provides byte-wide data interface compatible with 8-bit microcontrollers and legacy bus architectures. |
| Access Time | 45 ns - enables direct interfacing with ARM Cortex-M4/M7 MCUs running at ≤22 MHz without wait states. |
| Supply Voltage | 2.2 V to 3.6 V - supports single-supply operation across Li-ion (3.0–3.6 V) and regulated 2.5 V rails in portable instrumentation. |
| Standby Current | 7 µA max (Industrial) - extends battery life >10 years in always-on sensor nodes with periodic wake-up intervals. |
| Operating Temperature | –40 °C to +85 °C - qualified for under-hood automotive-A and industrial control cabinet deployment. |
| Data Retention Voltage | 1.5 V min - allows memory contents to persist during brown-out conditions or controlled power-down sequences. |
| Package Type | 36-ball VFBGA (6 × 8 mm, 0.5 mm pitch) - enables compact PCB layout in space-constrained wearable and ADAS camera modules. |
Pinout & Package
Package: 36-ball very fine-pitch ball grid array (VFBGA), 6 mm × 8 mm, 0.5 mm pitch, JEDEC MO-220 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 map. |
| I/O0–I/O7 | Bidirectional Data Lines | 8-bit parallel data path; tri-stated automatically on CE HIGH, OE HIGH, or WE LOW to prevent bus contention. |
| CE | Chip Enable | Active-LOW enable controlling power state: HIGH → automatic standby (≤7 µA); LOW → active mode. |
| OE | Output Enable | Active-LOW signal enabling read data output; must be LOW during read cycles and HIGH to disable outputs. |
| WE | Write Enable | Active-LOW control initiating write operations; concurrent LOW with CE defines write window per timing specs. |
| VCC | Power Supply | Primary 2.2–3.6 V supply; decoupling required within 5 mm due to fast switching transients (tRC = 45 ns). |
| VSS | Ground | Digital ground reference; two dedicated VSS balls (B1, D1) ensure low-impedance return path for I/O switching. |
| NC | No Connect | Unbonded die pads (pins B2, F1); must remain unconnected and unpopulated on PCB to avoid noise coupling. |
Key Features
| Feature | Design Value |
|---|---|
| MoBL® Ultra-Low Power Architecture | Reduces active current to 3.5 mA at 1 MHz and standby to 2.5 µA typical-enabling multi-year battery life in wireless sensor transmitters. |
| Automatic CE-Controlled Power-Down | Eliminates external power management circuitry; transitions to <7 µA standby within 45 ns of CE HIGH assertion. |
| Full-Voltage-Rate Timing Guarantees | All AC parameters (tRC, tDOE, tHZOE) specified over 2.2–3.6 V and –40 °C to +85 °C-no derating needed for wide-input-range designs. |
| Tri-State Output Control Logic | I/O pins enter high-Z on any combination of CE HIGH, OE HIGH, or WE LOW-preventing bus conflicts during reset or multi-device sharing. |
| Robust Data Retention | Maintains stored data at VCC ≥ 1.5 V and TA ≤ +85 °C, supporting graceful shutdown during power failure in automotive infotainment systems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 4-Mbit SRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IS62WV5128BLL-45NLI | 45 ns access, 2.7–3.6 V only, SOIC-32 package; no 2.2 V support or VFBGA option. | Lacks low-voltage operation and compact packaging-unsuitable for battery-powered or space-constrained designs. | Select if legacy SOIC footprint and 3.3 V-only systems require drop-in replacement with identical timing. |
| AS6C4008-55TIN | 55 ns access, 2.7–3.6 V, TSOP-II-32; higher standby current (25 µA typ) and no data retention below 2.0 V. | Cannot meet MoBL® battery-life targets or operate during brown-out events in automotive environments. | Choose only for cost-sensitive industrial controls where 55 ns latency and 3.3 V rail are acceptable. |
Compared with IS62WV5128BLL-45NLI and AS6C4008-55TIN, CY62148EV30LL-55SXIT uniquely combines 2.2 V operation, VFBGA-36 packaging, 7 µA max standby, and 1.5 V data retention-making it the sole choice for next-generation portable and automotive SRAM applications demanding ultra-low power and miniaturization.

FAQ
Is CY62148EV30LL-55SXIT pin-compatible with CY62148DV30?
Yes, CY62148EV30LL-55SXIT is explicitly pin-compatible with CY62148DV30 per the Cypress/Infineon datasheet. Both share identical VFBGA-36 pinout, address/data/control signal mapping, and power/ground ball locations-enabling direct PCB-level replacement without layout changes.
What is the maximum clock frequency supported for synchronous interface?
CY62148EV30LL-55SXIT is an asynchronous SRAM and does not use a clock signal. Its operation relies solely on CE, OE, and WE timing; the maximum effective interface rate is determined by tRC = 45 ns, supporting up to ~22 MHz random-access throughput without wait states.
Does this SRAM support battery backup mode with external capacitor?
No-CY62148EV30LL-55SXIT lacks built-in battery-switching circuitry or dedicated VBAT pin. However, its 1.5 V data retention threshold allows integration with external low-dropout regulators or supercapacitor hold-up circuits to maintain memory during main supply interruption.
Can I use the NC pins for mechanical anchoring or thermal relief?
No-NC pins (B2, F1) are unconnected on-die and must remain unpopulated and unconnected on the PCB. Using them for solder anchoring or thermal vias risks introducing noise coupling or mechanical stress that may compromise VFBGA joint reliability per JEDEC standards.
