Product details
Overview
CY62148DV30LL-55SXIT from Cypress Semiconductor is a 4-Mbit (512 K × 8) MoBL® CMOS static RAM with 55 ns access time, 2.2 V–3.6 V supply voltage, and industrial temperature range (–40 °C to +85 °C). It features ultra-low active current (1.5 mA at 1 MHz), automatic CE-controlled power-down, and high-impedance I/O tri-state control for portable memory subsystems in handheld instrumentation.
For engineers reviewing the CY62148DV30LL-55SXIT datasheet, CY62148DV30LL-55SXIT pinout, CY62148DV30LL-55SXIT application, or CY62148DV30LL-55SXIT equivalent, key selection criteria include standby current (2 µA typ), read cycle time (55 ns), data retention voltage (1.5 V), CE/OE/WE timing compatibility, and SOIC-32 package footprint alignment with legacy CY62148CV series.
Technical Context
This SRAM implements a full CMOS 512K × 8 asynchronous architecture with independent address decoding, sense amplifier array, and complementary metal oxide semiconductor logic for optimal speed/power trade-off. It supports three-state output control via OE and CE, and automatic low-power mode activation when CE is HIGH.
Timing behavior is defined by overlapping CE/WE/OE control signals: write requires CE and WE LOW; read requires CE and OE LOW with WE HIGH. Data retention operates down to 1.5 V with ICCDR = 6 µA, enabling battery-backed hold during brown-out conditions without external circuitry.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Organization | 512 K × 8 bits - provides byte-wide data bus interface compatible with 8-bit microcontrollers and legacy peripherals |
| Access Time | 55 ns - enables direct interfacing with 18 MHz synchronous buses or sub-20 MHz microprocessor address strobes |
| Supply Voltage Range | 2.2 V–3.6 V - supports single-supply operation across Li-ion (3.0–3.6 V) and regulated 2.5 V system rails |
| Active Current (1 MHz) | 1.5 mA typical - reduces average power to ~3.75 mW at 2.5 V, critical for battery runtime in portable devices |
| Standby Current | 2 µA typical - allows multi-week data retention on coin-cell backup without significant capacity loss |
| Data Retention Voltage | 1.5 V minimum - permits memory hold during deep sleep or partial power collapse without external supervisor IC |
| Operating Temperature | –40 °C to +85 °C - qualified for industrial-grade embedded systems including automotive infotainment head units |
Pinout & Package
Package: 32-pin Small-outline integrated circuit (SOIC), 300 mil body width, lead-free (Pb-free) finish, JEDEC MS-012AC compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A18 | Address inputs | 19-bit address bus supporting full 512 K-word decoding; A0 LSB, A18 MSB |
| I/O0–I/O7 | Bidirectional data bus | 8-bit parallel interface; high-impedance when CE HIGH, OE HIGH, or WE LOW |
| CE | Chip Enable | Active-LOW global enable; forces automatic power-down and high-Z I/O when HIGH |
| OE | Output Enable | Active-LOW read control; disables outputs (high-Z) when HIGH, independent of CE state |
| WE | Write Enable | Active-LOW write control; latches data on I/O pins when CE and WE both LOW |
| VCC | Power supply | 2.2–3.6 V core supply; decoupling capacitor required within 10 mm of pin 1 |
| VSS | Ground | Signal and power return reference; must be connected to low-impedance ground plane |

Equivalent & Alternatives
The following parts are listed as comparable options for similar static RAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IS62WV5128BLL-55QLI | 55 ns access, 2.5 V–3.6 V supply, 2 µA ISB, but lacks 2.2 V minimum VCC support | Not suitable for 2.2–2.5 V battery-only operation; requires LDO regulation if powered from single Li-ion cell | Select only if system uses regulated 2.7 V+ rail and requires higher production volume availability |
| AS6C4008-55TIN | 55 ns access, 2.7 V–3.6 V supply, 3 µA ISB, SOIC-32 package, but no 1.5 V data retention spec | Cannot retain data below 2.0 V; requires external supervisor or backup regulator for brown-out hold | Prefer where cost sensitivity outweighs ultra-low-VCC retention needs and industrial temp is not mandatory |
Compared with IS62WV5128BLL-55QLI and AS6C4008-55TIN, CY62148DV30LL-55SXIT uniquely supports 2.2 V operation and guaranteed 1.5 V data retention-critical for direct battery interfacing-while maintaining identical 55 ns timing and SOIC-32 footprint.

FAQ
What is the minimum VCC required to maintain data during standby?
The CY62148DV30LL-55SXIT guarantees data retention down to 1.5 V VCC when CE is HIGH and all inputs are held valid. At this voltage, typical retention current is 6 µA. Operation below 1.5 V risks data loss; no specification is provided for lower voltages.
Can OE be used independently of CE to disable outputs during read cycles?
Yes. When OE is HIGH while CE is LOW, outputs enter high-impedance state immediately (tHZOE ≤ 20 ns), allowing bus sharing without deselecting the device. This enables interleaved access with other peripherals on the same data bus without toggling CE.
Does this SRAM require an external clock signal?
No. The CY62148DV30LL-55SXIT is an asynchronous static RAM. All operations are controlled solely by edge- or level-sensitive CE, OE, and WE signals. No clock input or timing reference is needed, simplifying integration with microcontrollers lacking dedicated memory clocks.
Is the SOIC-32 package RoHS and REACH compliant?
Yes. The CY62148DV30LL-55SXIT uses a Pb-free (lead-free) SOIC-32 package fully compliant with EU RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006, including restrictions on SVHC substances at declared thresholds.
