Product details
Overview
CY62148G30-45SXI from Infineon is a 4-MB MoBL™ ultra-low-power SRAM with embedded ECC, organized as 512K words × 8-bit. It operates at 45 ns access time across 2.2 V–3.6 V supply, delivers 3.5 µA typical standby current, and supports TTL-compatible I/O for embedded memory subsystems in battery-powered industrial controllers.
For engineers reviewing the CY62148G30-45SXI datasheet, CY62148G30-45SXI pinout, CY62148G30-45SXI application, or CY62148G30-45SXI equivalent, this device serves as a drop-in replacement for legacy low-voltage SRAMs requiring ECC correction, stable data retention at 1.0 V, and dual-voltage-range compatibility in space-constrained designs.
Technical Context
This SRAM implements a synchronous read/write interface with three independent control inputs (CE, OE, WE) enabling precise memory access timing and bus contention management. Its internal ECC engine performs single-bit error correction on every read cycle without external logic or software intervention.
The device integrates row/column decoders, sense amplifiers, and dedicated ECC encoder/decoder blocks within a single CMOS die. It supports full data retention down to 1.0 V while maintaining functional integrity across –40°C to +85°C industrial temperature range.

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-power SRAM with ECC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ISSI IS62WV5128BLL-45NLI | No embedded ECC; requires external error detection logic or software overhead | Suitable where cost sensitivity outweighs reliability requirements in non-critical data paths | Select when ECC is not mandated and BOM cost reduction is primary objective |
| ON Semiconductor NVSRAM N25S80A-45G | Non-volatile SRAM with integrated EEPROM backup; higher write latency and lower endurance than CY62148G30 | Preferred for applications needing guaranteed data persistence after total power loss | Choose when true non-volatility (not just low-V retention) is required for mission-critical state storage |
Compared with IS62WV5128BLL-45NLI and N25S80A-45G, CY62148G30-45SXI uniquely balances hardware ECC, ultra-low standby, and wide voltage tolerance-making it optimal for battery-operated industrial edge devices where reliability and power efficiency are jointly constrained.

FAQ
Does CY62148G30-45SXI support automatic error correction during read operations?
Yes. The device performs single-bit error correction automatically on every read cycle using its embedded ECC decoder. No external logic or software intervention is required. Correction occurs transparently before data appears on I/O0–I/O7, and uncorrectable multi-bit errors are flagged via standard SRAM timing behavior (no dedicated error pin).
What is the maximum clock frequency supported for continuous read/write bursts?
The device does not use a clock input; it is an asynchronous SRAM. Maximum effective throughput is determined by access time: 45 ns allows sustained operation at 22.22 MHz (1/45 ns) when interfaced with a controller capable of meeting setup/hold timing. AC switching characteristics in the datasheet define valid timing margins for CE/OE/WE assertion.
Can CY62148G30-45SXI operate at 1.8 V supply?
No. This variant (CY62148G30) is specified only for 2.2 V–3.6 V operation. For 1.65 V–2.2 V operation, Infineon offers CY62148G18. Attempting 1.8 V operation on CY62148G30-45SXI violates the absolute maximum ratings and may result in data corruption or functional failure.
Is the SOIC package RoHS-compliant and lead-free?
Yes. The CY62148G30-45SXI in 32-pin SOIC packaging is Pb-free and RoHS-compliant, as confirmed in Infineon's ordering information (Section 14) and package diagrams (Section 15). The "SXI" suffix denotes industrial temperature grade and lead-free finish per JEDEC J-STD-609.
