Product details
Overview
CY62148DV30LL-70ZSXA from Cypress Semiconductor is a 4-Mbit (512K × 8) MoBL® CMOS static RAM optimized for automotive-A and industrial applications. It operates across 2.2 V–3.6 V, delivers 70 ns access time, draws only 1.5 mA typical active current at 1 MHz, and achieves ≤8 µA standby current. Its automatic CE-controlled power-down and high-impedance I/O states support battery-sensitive systems like telematics control units.
For engineers reviewing the CY62148DV30LL-70ZSXA datasheet, CY62148DV30LL-70ZSXA pinout, CY62148DV30LL-70ZSXA application, or CY62148DV30LL-70ZSXA equivalent, key selection criteria include its 70 ns read/write timing, 32-pin TSOP II Pb-free package, automotive-A temperature rating (–40°C to +85°C), ultra-low ISB2 standby current, and CE/OE/WE three-control interface for deterministic bus arbitration.
Technical Context
The CY62148DV30LL-70ZSXA implements a full CMOS 512K × 8 asynchronous SRAM architecture with independent address decoding, sense amplifiers, and data drivers. Its automatic power-down activates when CE is HIGH, forcing all I/Os into high-impedance and reducing ICC to ≤8 µA - verified under VCC = 3.6 V and VIN > VCC−0.2 V or < 0.2 V.
Timing is governed by overlapping CE and WE control: write cycles require CE and WE both LOW, while reads require CE and OE LOW with WE HIGH. All AC parameters - including tRC (70 ns), tACE (70 ns), and tHZOE (25 ns) - are specified over the full voltage (2.2–3.6 V) and temperature (–40°C to +85°C) range for automotive-A compliance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Organization | 512K words × 8 bits - supports byte-wide data bus interfacing without external demultiplexing |
| Access Time (tRC) | 70 ns - guarantees deterministic read/write latency for microcontroller-based real-time buffering |
| Supply Voltage Range | 2.2 V to 3.6 V - compatible with single-supply 2.5 V/3.3 V logic domains and brown-out tolerant operation |
| Active Current (ICC) | 1.5 mA typ @ 1 MHz - enables multi-second battery runtime in always-on vehicle event recorders |
| Standby Current (ISB2) | 8 µA max @ VCC = 3.6 V - meets automotive low-power sleep mode requirements per ISO 16750-2 |
| Operating Temperature | –40°C to +85°C (Automotive-A) - qualified for under-hood and infotainment module mounting locations |
| Package | 32-pin TSOP II (Pb-free) - surface-mount compatible with standard reflow profiles and IPC-7351B land patterns |
Pinout & Package
Package: 32-pin Thin Small Outline Package Type II (TSOP II), Pb-free, body size 11.8 mm × 13.9 mm × 1.2 mm, JEDEC MO-153 compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A18 | Address Inputs | 19-bit address bus supporting full 512K-word decoding; no internal latching - requires stable address during CE LOW |
| IO0–IO7 | Bidirectional Data I/O | CMOS-compatible 8-bit data bus; enters high-Z on CE HIGH, OE HIGH, or WE LOW - prevents bus contention |
| CE | Chip Enable | Active-LOW device select; initiates automatic power-down and disables outputs when HIGH |
| OE | Output Enable | Active-LOW read strobe; controls output driver enable independently of CE - enables memory-mapped peripheral sharing |
| WE | Write Enable | Active-LOW write strobe; combined with CE LOW to initiate write; forces IO pins to input mode during write |
| VCC | Power Supply | 2.2 V–3.6 V core supply; decoupling required within 5 mm of pins 1 and 32 per layout guidelines |
| VSS | Ground | Dual ground pins (pins 16 and 31) reduce ground bounce in high-speed burst transfers |
Key Features
| Feature | Design Value |
|---|---|
| MoBL® Ultra-Low Power | 1.5 mA typical ICC at 1 MHz and ≤8 µA ISB2 enable >10-year coin-cell operation in vehicle black-box loggers |
| Automotive-A Qualification | –40°C to +85°C operation with full AC/DC specs validated per AEC-Q100 stress test conditions |
| Three-Enable Control Architecture | Independent CE/OE/WE allows flexible bus arbitration - e.g., OE gating for shared-memory peripherals without disabling chip |
| Pb-Free TSOP II Packaging | RoHS-compliant 32-pin TSOP II footprint ensures drop-in replacement in legacy 3.3 V automotive PCBs |
| Automatic Power-Down | No external control needed: CE HIGH alone reduces ICC to ISB2 level - eliminates need for power-gating logic |
Applications
| Telematics Control Unit (TCU) | Advanced Driver Assistance System (ADAS) Camera Buffer |
|---|---|
Use Scenario: Stores GPS trajectory logs and cellular handover metadata during intermittent network connectivity. IC Role / Device Role / Timing Role: Asynchronous SRAM buffer between MCU and modem IC; absorbs burst writes at 10–50 kB/s with 70 ns random access. Use Value: 8 µA ISB2 enables TCU to maintain RTC and wake-on-event capability for >3 months on backup supercapacitor. |
Use Scenario: Temporarily holds uncompressed frame data from 1.3 MP image sensor before JPEG compression. IC Role / Device Role / Timing Role: High-speed frame line buffer; interfaces directly to sensor parallel output bus using CE/OE handshaking. Use Value: 70 ns tRC supports ≥15 fps full-resolution capture without pipeline stalls or FIFO overflow. |
| Infotainment Head Unit Audio DSP Cache | Electronic Parking Brake (EPB) Controller Memory |
Use Scenario: Caches FIR filter coefficients and audio sample buffers for real-time equalization and noise cancellation. IC Role / Device Role / Timing Role: Low-latency scratchpad memory mapped to DSP's external memory interface; accessed via burst reads. Use Value: 2.2–3.6 V operating range matches DSP I/O voltage, eliminating level-shifter components. |
Use Scenario: Stores brake actuator calibration tables and fault history logs in fail-safe ECU with ASIL-B compliance. IC Role / Device Role / Timing Role: Non-volatile shadow RAM (paired with EEPROM); retains critical data during main power loss via VDR = 1.5 V retention. Use Value: 1.5 V data retention threshold allows seamless switchover to backup power without data corruption. |
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-70NLI | Same 512K × 8 organization, 70 ns speed, but rated only for industrial (–40°C to +85°C), not automotive-A | Lacks AEC-Q100 qualification; unsuitable for under-dash or engine-bay mounting | Select only for non-automotive industrial control where extended temp validation is unnecessary |
| Cypress CY62148EV30LL-70ZSXI | Successor generation with identical pinout and timing, but enhanced data retention (VDR = 1.2 V vs. 1.5 V) and lower ISB2 (≤5 µA) | Backward-compatible upgrade path; requires no PCB change but improves battery life in always-on modules | Preferred for new designs targeting longer service intervals and lower quiescent power |
Compared with IS62WV5128BLL-70NLI, CY62148DV30LL-70ZSXA provides certified automotive-A reliability and higher VDR margin; versus CY62148EV30LL-70ZSXI, it trades slightly higher ISB2 for proven field deployment in legacy telematics platforms.

FAQ
Is CY62148DV30LL-70ZSXA pin-compatible with CY62148CV30 series devices?
Yes - it is explicitly pin-compatible with CY62148CV25, CY62148CV30, and CY62148CV33 per the datasheet Feature section. The 32-pin TSOP II footprint, signal assignment (A0–A18, IO0–IO7, CE/OE/WE, VCC/VSS), and power sequencing requirements match exactly, enabling direct substitution in existing layouts.
What is the minimum VCC required to retain data during power loss?
The device guarantees data retention down to VCC = 1.5 V (VDR parameter), with ICCDR ≤6 µA at that voltage. This allows integration with supercapacitor or lithium-thionyl chloride backup circuits that decay slowly below nominal 3.3 V, preserving critical fault logs during ignition-off periods.
Does CY62148DV30LL-70ZSXA support partial-address write operations?
No - it is a byte-wide (x8) asynchronous SRAM with no internal write masking. All eight IO lines participate in every write cycle; partial-byte updates require external logic or MCU software handling of read-modify-write sequences to avoid unintended data corruption.
How does the automatic power-down feature interact with OE and WE signals?
Automatic power-down activates solely on CE HIGH - independent of OE or WE state. When CE is HIGH, outputs go high-Z and ICC drops to ISB2 regardless of OE/WE levels. OE and WE only affect I/O direction and data transfer timing when CE is LOW.
