Product details
Overview
CY62148EV30LL-45BVXI 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 (2.5 µA typ), active current of 3.5 mA at 1 MHz, and automatic power-down when deselected-enabling extended battery life in portable memory subsystems.
For engineers reviewing the CY62148EV30LL-45BVXI datasheet, CY62148EV30LL-45BVXI pinout, CY62148EV30LL-45BVXI application, or CY62148EV30LL-45BVXI equivalent, this device supports low-power embedded systems requiring fast, reliable parallel SRAM with CE/OE/WE control, high-impedance I/O tri-state behavior, and Pb-free 36-ball VFBGA packaging.
Technical Context
The CY62148EV30LL-45BVXI implements a full CMOS 512K × 8 asynchronous SRAM architecture with independent address decoding, sense amplifiers, and automatic power-down logic triggered by CE HIGH. Its timing is defined by tRC = 45 ns, tAA = 45 ns, and tDOE = 22 ns under industrial conditions at VCC = 3.6 V.
It supports three distinct operating modes: active read (CE/OE LOW, WE HIGH), active write (CE/WE LOW), and standby (CE HIGH), with all I/O pins entering high-impedance state during deselect, output disable, or write cycles. Data retention is guaranteed down to VCC = 1.5 V with ICCDR ≤ 8.8 µA.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Organization | 512K × 8 bits - provides byte-wide data interface compatible with 8-bit microcontrollers and legacy bus architectures. |
| Access Time (tAA) | 45 ns max - enables direct interfacing with MCUs running at ≤22 MHz without wait states. |
| Supply Voltage Range | 2.2 V to 3.6 V - supports single-supply operation across Li-ion battery discharge profiles and mixed-voltage system rails. |
| Standby Current (ISB2) | 7 µA max at 3.6 V, –40 °C to +85 °C - reduces quiescent power in always-on subsystems such as real-time clocks or sensor buffers. |
| Active Current (ICC) | 20 mA max at fmax, 3.6 V - limits peak power draw during burst reads/writes in portable instrumentation. |
| Data Retention Voltage | 1.5 V min - allows memory contents to persist through brown-out events or controlled low-power sleep modes. |
| Package Type | 36-ball VFBGA (6 × 6 mm, 0.5 mm pitch) - enables compact PCB layout for space-constrained handheld and automotive ECUs. |
Pinout & Package
Package: 36-ball very fine-pitch ball grid array (VFBGA), 6 mm × 6 mm, 0.5 mm pitch, Pb-free, RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A18 | Address inputs | 19-bit address bus supporting 512K-word addressing; A18 is MSB for full 512K × 8 capacity. |
| I/O0–I/O7 | Bi-directional data bus | 8-bit parallel interface; enters high-Z on CE HIGH, OE HIGH, or WE LOW to prevent bus contention. |
| CE | Chip Enable | Active-low enable controlling full device power state; HIGH forces automatic power-down and high-Z I/O. |
| OE | Output Enable | Active-low control for read data output only; does not affect write or power state. |
| WE | Write Enable | Active-low signal initiating write cycle; must be LOW with CE LOW and valid address/data present. |
| VCC | Power supply | Single 2.2–3.6 V supply; decoupling required per JEDEC guidelines due to 45 ns switching transients. |
| VSS | Ground | Dual ground balls (pins B1, H1) provide low-inductance return path for digital and I/O currents. |
| NC | No-connect | Pins D1 and F1 are unconnected on die; must be left floating or tied to ground per board design rules. |
Key Features
| Feature | Design Value |
|---|---|
| MoBL® (More Battery Life) | Ultra-low 2.5 µA typical standby current extends operational runtime in battery-powered telemetry modules. |
| Automatic Power-Down | Hardware-triggered transition to sub-µA retention mode when CE is deasserted-no software or external logic required. |
| Tri-State Output Control | Independent OE and CE controls allow flexible bus sharing in multi-peripheral systems without external bus transceivers. |
| Wide Voltage Operation | 2.2–3.6 V range eliminates need for level shifters when interfacing with 2.5 V or 3.3 V MCUs and peripherals. |
| Pb-Free VFBGA Packaging | 36-ball footprint supports automated assembly and meets automotive AEC-Q200 stress requirements for vibration and thermal cycling. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar asynchronous SRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ISSI IS62WV5128BLL-45NLI | Same 512K × 8 organization, 45 ns speed, but uses 32-pin TSOP-II package and has higher ISB2 (15 µA max). | Larger footprint and less suitable for space-constrained portable designs; better thermal dissipation in fixed-mount industrial controllers. | Select when board layout accommodates TSOP-II and higher standby current is acceptable for cost-sensitive deployments. |
| Renesas R1LV5128ASBG-45GBG | Identical VFBGA-36 pinout and 45 ns timing, but rated only for industrial (–40 °C to +85 °C), not automotive-A. | Not qualified for automotive body electronics requiring AEC-Q100 Grade 2 temperature validation. | Choose for non-automotive industrial applications where identical mechanical fit and timing simplify second-source qualification. |
Compared with IS62WV5128BLL-45NLI and R1LV5128ASBG-45GBG, the CY62148EV30LL-45BVXI uniquely combines automotive-A qualification, lowest standby current (7 µA max), and Pb-free VFBGA in a single offering-making it optimal for next-generation portable and automotive edge nodes demanding minimal power and maximum reliability.

FAQ
Is CY62148EV30LL-45BVXI pin-compatible with CY62148DV30?
Yes, CY62148EV30LL-45BVXI is explicitly stated as pin-compatible with CY62148DV30 in the official datasheet. Both share identical 36-ball VFBGA pinout, address/data/control signal mapping, and electrical timing specifications-enabling drop-in replacement in existing designs without PCB revision.
What is the maximum clock frequency supported for synchronous interface?
The CY62148EV30LL-45BVXI is an asynchronous SRAM and does not include an internal clock input or synchronous interface logic. Its maximum effective throughput is determined by tRC = 45 ns, yielding a theoretical upper limit of ~22.2 MHz for consecutive random-access cycles, but no clock signal is required or accepted.
Does this SRAM support battery backup or nonvolatile operation?
No, CY62148EV30LL-45BVXI is a volatile CMOS SRAM. It retains data only while powered above VDR = 1.5 V and loses contents upon complete power removal. For nonvolatile storage, external EEPROM or FRAM must be used alongside this device for data logging or configuration persistence.
Can I leave unused address pins floating in my design?
No. All address inputs (A0–A18) must be driven to valid logic levels (VIL ≤ 0.6 V or VIH ≥ 2.2 V depending on VCC) during operation. Floating address lines cause undefined memory location access and potential data corruption; tie unused pins to VSS or VCC via 10-kΩ resistors if not actively driven.
