Product details

Overview

CY62148G30-45ZSXIT from Infineon is a 4-MB MoBL™ ultra-low-power SRAM with embedded ECC, organized as 512K × 8-bit. It operates across 2.2 V–3.6 V, delivers 45 ns access time, draws ≤8.7 µA standby current, and supports TTL-compatible I/O for battery-backed industrial memory applications.

For engineers reviewing the CY62148G30-45ZSXIT datasheet, CY62148G30-45ZSXIT pinout, CY62148G30-45ZSXIT application, or CY62148G30-45ZSXIT equivalent, key selection criteria include ECC-enabled single-bit error correction, multi-voltage support (2.2–3.6 V), 32-pin TSOP II package compatibility, and sub-10 µA standby power for always-on systems.

Technical Context

This SRAM implements a synchronous CMOS architecture with dedicated row/column decoders, sense amplifiers, and integrated ECC encoder/decoder logic-enabling real-time single-bit error detection and correction without external circuitry. The device uses standard asynchronous control signals (CE, OE, WE) and does not perform automatic write-back on error detection.

It supports three distinct V_CC operating ranges (1.65–2.2 V, 2.2–3.6 V, 4.5–5.5 V); this variant is specified for 2.2–3.6 V operation with 45 ns access time and guaranteed 3.5 µA typical / 8.7 µA maximum standby current at T_A = –40°C to +85°C.

Key Specifications

Parameter	Value and Actual Design Meaning
Memory Size	4 MB (512K words × 8-bit) - provides sufficient buffer space for firmware caching or real-time data logging in resource-constrained edge nodes.
Access Time	45 ns - enables direct interface with microcontrollers running at ≤22 MHz without wait states.
Standby Current	Max 8.7 µA - ensures multi-year battery life in coin-cell-powered IoT sensors during deep-sleep modes.
V_CC Range	2.2 V to 3.6 V - compatible with Li-ion, Li-Po, and regulated 3.3 V rails without level-shifting.
ECC Function	Embedded single-bit error correction - detects and corrects soft errors in memory cells without software overhead or external logic.
Data Retention	1.0 V minimum - maintains stored data during brown-out conditions down to critical supply thresholds.
I/O Compatibility	TTL-compatible inputs/outputs - simplifies integration with legacy 3.3 V logic families without bus buffers.

Pinout & Package

Package: 32-pin TSOP II (Thin Small Outline Package, Type II), 12.0 mm × 20.0 mm body, 0.5 mm pitch, RoHS-compliant, lead-free.

Pin/Terminal	Circuit Role	Design Meaning
A0–A18	Address Inputs	19-bit address bus supporting full 512K-word addressing; no multiplexing required.
I/O0–I/O7	Bidirectional Data Bus	8-bit parallel interface; placed in high-impedance state when CE HIGH or OE de-asserted.
/CE	Chip Enable (active LOW)	Primary device select; disables internal circuitry and reduces current draw to standby level when HIGH.
/OE	Output Enable (active LOW)	Controls output drivers only; allows read operations while keeping address/data paths active.
/WE	Write Enable (active LOW)	Initiates write cycle; latches data from I/O lines into memory array when asserted with /CE LOW.
V_CC	Power Supply	Single-supply input for core and I/O; accepts 2.2–3.6 V with internal regulation for stable SRAM operation.
V_SS	Ground	Digital ground reference for all logic and memory circuits; requires low-impedance connection to minimize noise coupling.

Key Features

Feature	Design Value
Ultra-low standby power	8.7 µA max at 85°C - extends battery runtime in portable medical monitors and remote telemetry units.
Embedded ECC	Hardware-based single-bit error correction - eliminates need for external ECC logic or software polling in safety-critical storage.
Multi-voltage support	2.2–3.6 V operation - enables drop-in replacement across designs using different LDO outputs or battery chemistries.
1.0-V data retention	Retains valid data down to 1.0 V - prevents memory corruption during power-fail sequences in industrial PLCs.
TTL-compatible I/O	Meets VIH/VIL thresholds for 3.3 V logic families - avoids level translators in mixed-voltage systems with legacy controllers.

Applications

Medical Wearables

Industrial Data Loggers

Use Scenario: Continuous ECG waveform buffering in patch-style monitors powered by CR2032 batteries.

IC Role / Device Role / Timing Role: Asynchronous SRAM buffer storing raw sensor samples prior to BLE transmission.

Use Value: 8.7 µA standby current enables >3 months of operation between battery replacements; ECC prevents corrupted waveform artifacts.

Use Scenario: Hourly temperature/humidity snapshots stored in factory-floor environmental sensors.

IC Role / Device Role / Timing Role: Nonvolatile shadow RAM holding last valid reading during brown-out events.

Use Value: 1.0-V data retention preserves integrity through 100+ ms power dips; 45 ns access supports rapid burst reads for diagnostics.

Smart Metering Modules

Avionics Health Monitors

Use Scenario: Tamper-event timestamping and energy consumption history in ANSI C12.22-compliant meters.

IC Role / Device Role / Timing Role: Dedicated ECC-protected memory bank for secure event logs.

Use Value: Embedded ECC eliminates risk of undetected bit flips in long-term archival data; 2.2–3.6 V range matches meter's DC-DC output.

Use Scenario: Real-time vibration signature capture in engine-mounted health monitoring units.

IC Role / Device Role / Timing Role: High-reliability buffer feeding FFT processing pipeline in DO-254-certified hardware.

Use Value: Industrial-grade –40°C to +85°C operation ensures functionality at altitude; 45 ns timing meets deterministic latency budgets.

Equivalent & Alternatives

The following parts are listed as comparable options for similar SRAM with ECC applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
ISSI IS62WV5128BLL-45NLI	No embedded ECC; requires external error handling or software mitigation.	Suitable for non-safety-critical buffering where cost sensitivity outweighs reliability requirements.	Select if ECC is not mandated and BOM cost reduction is primary objective.
Cypress S27KL0641DPBHI020	Serial Quad SPI NOR Flash with ECC; 64 Mbit density, slower random access (≥8 µs), no true SRAM interface.	Used for code storage with error resilience, not for high-speed data buffering.	Choose only for firmware storage with ECC-not as functional replacement for SRAM-based data buffers.

Compared with IS62WV5128BLL-45NLI and S27KL0641DPBHI020, CY62148G30-45ZSXIT uniquely combines 45 ns random access, hardware ECC, and ultra-low standby current in a parallel SRAM interface-making it irreplaceable for battery-powered, safety-aware data buffering where both speed and integrity are non-negotiable.

FAQ

Does CY62148G30-45ZSXIT support automatic error correction write-back?

No. The device performs single-bit error detection and correction on read operations but does not automatically rewrite corrected data back to the memory array. Error correction is transparent to the host system, and no write-back cycle is triggered upon correction-this behavior is explicitly documented in the datasheet note on page 1.

What is the maximum clock frequency supported for continuous read/write bursts?

CY62148G30-45ZSXIT is an asynchronous SRAM and does not use a clock signal. Its maximum sustained data throughput is determined by access time: at 45 ns, it supports up to 22.22 MHz random read/write cycles under worst-case timing conditions with proper setup/hold margins.

Can this part operate reliably at 1.8 V?

No. CY62148G30-45ZSXIT is rated only for 2.2 V to 3.6 V operation. Operation below 2.2 V falls outside its specified operating range and may result in undefined behavior, timing violations, or failure to retain data-even though some units may function intermittently at 1.8 V.

Is the 32-pin TSOP II package pin-compatible with CY62148G18 or CY62148G variants?

Yes. All CY62148G family members-including CY62148G18, CY62148G30, and CY62148G-share identical 32-pin TSOP II and SOIC pinouts and signal definitions. Voltage range and speed grades differ, but PCB layout and interface logic remain fully interchangeable.
