Product details
Overview
CY62148EV30LL-45ZSXIT from Infineon Technologies (formerly Cypress) is a 4-Mbit (512K × 8) CMOS static RAM with 45 ns access time, operating across 2.2 V–3.6 V supply, rated for –40 °C to +85 °C industrial/automotive-A environments, and featuring ultra-low standby current (7 µA max) and active current (6 mA max at fmax). It serves as main memory or buffer in portable battery-powered systems requiring fast, low-power volatile storage.
For engineers reviewing the CY62148EV30LL-45ZSXIT datasheet, CY62148EV30LL-45ZSXIT pinout, CY62148EV30LL-45ZSXIT application, or CY62148EV30LL-45ZSXIT equivalent, key selection criteria include VFBGA-36 package compatibility, CE/OE/WE control timing compliance, MoBL® low-power retention behavior, and pin-for-pin replacement feasibility with CY62148DV30 in space-constrained embedded designs.
Technical Context
This SRAM implements a fully decoded 512K × 8 architecture with synchronous address latch and tri-state I/O drivers. Its automatic power-down logic activates when CE is HIGH, reducing ICC to ≤7 µA while maintaining data integrity down to 1.5 V VCC during retention mode.
Timing is governed by strict AC parameters: tRC = 45 ns, tAA = 45 ns, tDOE = 22 ns, and tPD = 45 ns - all guaranteed over full voltage (2.2–3.6 V) and temperature (–40 °C to +85 °C) ranges, enabling reliable integration into high-speed microcontroller bus interfaces without wait states.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Size | 4 Mbit (512K × 8), providing byte-wide data path compatible with 8-bit MCU buses and legacy controllers. |
| Access Time | 45 ns max - enables direct connection to 22 MHz synchronous bus clocks without cycle stretching. |
| Supply Voltage | 2.2 V to 3.6 V - supports single-supply operation across Li-ion battery discharge profiles (3.6 V → 2.5 V). |
| Standby Current | 7 µA max (Industrial) - extends battery life >10× vs. standard SRAMs in always-on sensor nodes. |
| Operating Temperature | –40 °C to +85 °C - qualified for automotive cabin modules and industrial edge controllers. |
| Package | 36-ball VFBGA (6 mm × 8 mm, 0.5 mm pitch) - optimized for compact PCB layouts in handheld and telematics units. |
| Data Retention Voltage | 1.5 V min - maintains stored contents during brown-out or controlled shutdown sequences. |
Pinout & Package
Package: 36-ball very fine-pitch ball grid array (VFBGA), 6 mm × 8 mm body, 0.5 mm pitch, JEDEC MO-276 compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A18 | Address Inputs | 19-bit address bus supporting full 512K-word decoding; no external address latching required. |
| I/O0–I/O7 | Bidirectional Data Bus | CMOS-compatible 8-bit I/O with high-impedance state on CE HIGH, OE HIGH, or WE LOW - enables bus sharing. |
| CE | Chip Enable | Active-LOW enable controlling both access and automatic power-down; dominant control for system-level sleep coordination. |
| OE | Output Enable | Active-LOW output gate; decouples data bus without affecting internal state or power mode. |
| WE | Write Enable | Active-LOW write strobe; combined with CE LOW initiates write cycle; independent of OE state. |
| VCC | Power Supply | Single 2.2–3.6 V supply; internally regulated for stable core voltage across rail variation. |
| VSS | Ground | Dual ground balls (pins B1, H1) minimize noise coupling and improve signal integrity in high-speed reads. |
| NC | No Connect | Pins D1 and F1 are unconnected on die - must be left floating or tied to ground per layout guidelines. |
Key Features
| Feature | Design Value |
|---|---|
| MoBL® Ultra-Low Power | 2.5 µA typical standby current enables >1-year battery life in coin-cell–powered IoT endpoints. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar SRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY62148DV30-45ZSXI | Same 4-Mbit organization and 45 ns speed, but older Cypress die revision; lacks updated data retention spec at 1.5 V. | Valid for legacy designs where qualification to AEC-Q100 Grade 2 is not required. | Select only if existing design validation covers original CY62148DV30 timing margins and thermal derating. |
| IS62WV5128BLL-45NLI | 45 ns access, 512K × 8, but requires 3.3 V ±10% supply; higher ISB (15 µA max) and no 2.2 V operation. | Suitable for fixed 3.3 V industrial systems with less stringent battery-life requirements. | Choose when board already uses 3.3 V LDO and thermal profile stays below 70 °C ambient. |
Compared with CY62148DV30-45ZSXI, the CY62148EV30LL-45ZSXIT adds guaranteed 1.5 V data retention and tighter ISB2 spec; versus IS62WV5128BLL-45NLI, it delivers wider voltage range and lower standby power - making it optimal for battery-operated or automotive-grade deployments.

FAQ
Is CY62148EV30LL-45ZSXIT pin-compatible with CY62148DV30 in VFBGA packages?
Yes - both parts share identical 36-ball VFBGA pinouts, address/data/control signal mapping, and power/ground ball locations. No PCB redesign is needed when migrating from CY62148DV30-45ZSXI to CY62148EV30LL-45ZSXIT, though layout review for thermal pad soldering and decoupling is recommended per Infineon's AN98523.
What is the minimum VCC required to retain data without refresh?
The device guarantees data retention down to 1.5 V VCC when CE is HIGH and ambient temperature remains within –40 °C to +85 °C. At this voltage, ICCDR is specified at 8.8 µA max, enabling extended hold times during brown-out or backup power transitions.
Does CY62148EV30LL-45ZSXIT support partial-address decoding or require full A0–A18?
It requires full 19-bit address decoding (A0–A18) - the internal decoder is hardwired for 512K × 8 organization with no address aliasing or partial decode modes. External address lines must drive all 19 bits; unused upper address bits cannot be masked or ignored without causing unintended memory access.
Can OE and WE be tied together for simplified control in write-only applications?
No - OE and WE serve independent functions: OE controls output driver enable, while WE controls write latch enable. Tying them risks bus contention during read-modify-write sequences and violates timing specs for tLZOE, tHZOE, and tPWE. Separate routing is mandatory for compliant operation per Figure 8 in datasheet Rev. *X.
