Product details
Overview
CY62148G18-55ZSXIT from Infineon is a 4-MB MoBL™ ultra-low-power SRAM with embedded ECC, organized as 512K × 8-bit, operating at 55 ns access time across 1.65–2.2 V supply. It delivers 3.5 µA typical standby current, supports TTL-compatible I/O, and targets battery-backed memory in industrial instrumentation and portable medical devices.
For engineers reviewing the CY62148G18-55ZSXIT datasheet, CY62148G18-55ZSXIT pinout, CY62148G18-55ZSXIT application, or CY62148G18-55ZSXIT equivalent, key selection criteria include its triple-voltage-range support (1.65–2.2 V), ECC-enabled single-bit error correction without automatic write-back, and SOIC/TSOP II package compatibility for space-constrained PCB layouts.
Technical Context
This SRAM implements a synchronous CMOS architecture with dedicated row/column decoders, sense amplifiers, and separate ECC encoder/decoder blocks. Its logic block diagram confirms independent ECC processing on read/write paths, with no hardware-level error recovery beyond detection and correction of single-bit errors in data words.
Control interface uses standard asynchronous protocol: chip enable (/CE), output enable (/OE), and write enable (/WE) drive all timing modes. All eight bidirectional I/O lines enter high-impedance state when /CE is HIGH or /OE is deasserted, ensuring clean bus isolation during deselect.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory size | 4 MB (512K × 8-bit) - supports full byte-wide data transfers without address remapping |
| Access time | 55 ns - defines maximum clock rate of 18.18 MHz for burst-free sequential reads |
| Supply voltage range | 1.65 V to 2.2 V - enables direct integration with 1.8 V logic domains and low-power microcontrollers |
| Standby current | 3.5 µA typical - extends battery life in always-on monitoring systems by minimizing quiescent drain |
| ECC capability | Single-bit error correction - detects and corrects bit flips in stored data without software intervention |
| Data retention | 1.0 V minimum - maintains valid data during brown-out conditions down to 1 V supply |
| I/O compatibility | TTL-compatible - ensures interoperability with legacy 5 V or mixed-voltage system buses |
Pinout & Package
Package: 32-pin SOIC (Small Outline Integrated Circuit), RoHS-compliant, surface-mountable with 0.025-inch lead pitch.
| 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; enters HI-Z when /CE HIGH or /OE deasserted |
| /CE | Chip enable (active LOW) | Primary device select; disables internal circuitry and reduces current draw to ISB2 level |
| /OE | Output enable (active LOW) | Controls output drivers only; does not affect internal power state or ECC operation |
| /WE | Write enable (active LOW) | Initiates write cycle; triggers ECC encoding before data storage into RAM array |
| VCC | Power supply | Supports three discrete voltage ranges (1.65–2.2 V, 2.2–3.6 V, 4.5–5.5 V); must be stable before access |
| VSS | Ground reference | Single ground pin; requires low-inductance connection to minimize noise coupling into sensitive SRAM core |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low standby power | 3.5 µA typical - enables multi-year battery operation in energy-harvesting sensor nodes |
| Embedded ECC | Hardware-based single-bit correction - eliminates need for external error-checking logic or firmware overhead |
| Triple voltage range support | 1.65–2.2 V / 2.2–3.6 V / 4.5–5.5 V - allows reuse across 1.8 V, 3.3 V, and 5 V system designs without redesign |
| 1.0-V data retention | Maintains stored data at VCC ≥ 1.0 V - supports graceful shutdown during power failure without data loss |
| TTL-compatible I/O | Meets VIH/VIL thresholds across all supported VCC ranges - ensures reliable interfacing with diverse controller families |

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-55MLI | No embedded ECC; requires external error-handling logic | Suitable only where data integrity is managed at system level | Select if cost sensitivity outweighs ECC requirement and firmware can implement checksums |
| Cypress S27KL0641DPBHI020 | Serial Quad SPI NOR Flash with ECC; 64 Mb density; slower random access | Used for code storage, not high-speed data buffering | Select only for boot code storage with ECC-not as SRAM replacement |
Compared with IS62WV5128BLL-55MLI and S27KL0641DPBHI020, CY62148G18-55ZSXIT uniquely combines byte-wide parallel interface, 55 ns access, and hardware ECC-enabling drop-in replacement in legacy SRAM designs requiring fault-tolerant data buffering without architectural changes.

FAQ
Does CY62148G18-55ZSXIT support automatic error correction and write-back?
No. The device performs single-bit error correction on read operations but does not implement automatic write-back to repair corrupted bits in the memory array. Correction occurs only in the data path; the original faulty word remains unmodified in the RAM cell unless rewritten by the host system.
What is the minimum VCC required to retain data without refresh?
Data retention is guaranteed down to 1.0 V VCC across the full industrial temperature range (−40°C to +85°C). Below this threshold, data integrity is not assured, and the device may lose stored contents even in standby mode.
Can CY62148G18-55ZSXIT operate at 3.3 V supply?
Yes. The part supports 2.2 V to 3.6 V operation per its second voltage range. At 3.3 V, it meets all AC/DC specifications including 55 ns access time and 3.5 µA typical standby current, provided ambient temperature stays within −40°C to +85°C.
Is the SOIC package of CY62148G18-55ZSXIT pin-compatible with TSOP II variants?
Yes. Both 32-pin SOIC and 32-pin TSOP II packages share identical pin numbering and signal assignments per Infineon's datasheet Figures 1 and 2. Layout adaptation is required for footprint, but no signal re-routing is needed.
