Product details
Overview
CY62148VNLL-70ZSXIT from Cypress Semiconductor is a 4 Mbit (512K × 8) low-power CMOS static RAM with 2.7–3.6 V supply range, 70 ns access time, and automatic CE-controlled power-down mode reducing standby current to 2 μA. It features TTL-compatible I/O, high-impedance tri-state outputs, and is qualified for industrial temperature range (–40°C to +85°C). Used in battery-powered portable electronics requiring non-volatile data retention during sleep.
For engineers reviewing the CY62148VNLL-70ZSXIT datasheet, CY62148VNLL-70ZSXIT pinout, CY62148VNLL-70ZSXIT application, or CY62148VNLL-70ZSXIT equivalent, key selection criteria include ultra-low ISB2 (2–20 μA), guaranteed tRC = 70 ns at VCC = 3.6 V, CMOS-level input thresholds, data retention down to 1.0 V, and dual-package availability (TSOP II and SOIC).
Technical Context
This SRAM implements a full synchronous read/write interface with independent chip enable (CE), output enable (OE), and write enable (WE) controls. Address decoding supports 19-bit addressing (A0–A18) for 512K-word access, and I/O pins (I/O0–I/O7) serve bidirectional data paths with controlled bus contention via three-state logic.
Power management is hardware-automated: when CE is HIGH and all inputs are stable (CMOS levels), the device enters automatic power-down mode-reducing ICC to ISB1/ISB2 levels without external control signals. Data retention remains valid down to VCC = 1.0 V with ICCDR ≤ 5.5 μA.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Size | 4 Mbit (512K × 8), enabling byte-wide data access without multiplexing |
| Access Time (tRC) | 70 ns max at VCC = 3.6 V, supporting 14.3 MHz burst read/write cycles |

Equivalent & Alternatives
The following parts are listed as comparable options for similar SRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ISSI IS62WV5128BLL-70NLI | Same density (512K × 8), 70 ns speed, but wider VCC range (2.7–5.5 V); higher ISB (15 μA typ) | Supports mixed-voltage systems (e.g., legacy 5 V logic interfacing), less optimal for ultra-low-power battery use | Select if 5 V tolerance or legacy interface compatibility is required; avoid for sub-μA sleep-critical designs |
| ON Semiconductor NVSRAM NVTFS256K8PLFTBG | Non-volatile variant with integrated EEPROM backup; slower write (100+ ns), higher ICC (10 mA active) | Eliminates external backup battery/capacitor; suited for data-logging where power loss must not corrupt last state | Choose only when true non-volatility justifies 3× higher active current and 40% slower access |
Compared with IS62WV5128BLL-70NLI and NVTFS256K8PLFTBG, CY62148VNLL-70ZSXIT delivers the lowest standby power and tightest timing consistency across voltage/temperature, making it optimal for energy-constrained portable systems where volatility is acceptable.

FAQ
What is the minimum VCC required to retain data in CY62148VNLL-70ZSXIT?
The device guarantees data retention down to VCC = 1.0 V under specified conditions (CE HIGH, inputs stable, no signal exceeding VCC + 0.3 V). At this voltage, ICCDR is rated ≤ 5.5 μA. This allows integration into systems with brown-out detection or backup power schemes where main supply may dip below 2.7 V without memory loss.
Does CY62148VNLL-70ZSXIT require external pull-up resistors on I/O lines?
No external pull-ups are required. The I/O pins (I/O0–I/O7) are fully TTL-compatible with defined VIH (≥2.2 V at VCC = 3.6 V) and VIL (≤0.8 V at VCC = 2.7 V) thresholds, and exhibit high-impedance states during deselect, OE HIGH, or write cycles. Pull-ups would interfere with bidirectional operation and violate AC timing specifications.
Can CY62148VNLL-70ZSXIT be used with a 5 V microcontroller interface?
No-it is not 5 V tolerant. Absolute maximum input voltage is VCC + 0.5 V, and VCC is limited to 3.6 V max. Direct connection to 5 V logic will exceed VIH/VIL limits and risk damage. A level-shifting circuit or 3.3 V–compatible MCU is mandatory for safe operation.
How does the automatic power-down feature activate, and is it controllable?
Automatic power-down activates when CE is HIGH and all address/data/control inputs remain static (no toggling) for >10 ns. It requires no software or external signal-only stable CMOS-level inputs. The feature cannot be disabled; however, asserting CE LOW immediately resumes full-speed operation with no wake-up latency.
