Product details
Overview
CY62146GE-45ZSXI from Cypress Semiconductor is a 4-Mbit (256K × 16) MoBL® SRAM with embedded single-bit error-correcting code (ECC), TTL-compatible I/Os, and an active-HIGH ERR output pin for real-time error detection/correction. It operates across 2.2 V–3.6 V or 4.5 V–5.5 V supply ranges, delivers 45 ns access time, and draws only 3.5 µA typical standby current - deployed in industrial control modules requiring data integrity under extended temperature (–40 °C to +85 °C).
For engineers reviewing the CY62146GE-45ZSXI datasheet, CY62146GE-45ZSXI pinout, CY62146GE-45ZSXI application, or CY62146GE-45ZSXI equivalent, key selection criteria include ECC-enabled memory reliability, dual-voltage support, TSOP II package compatibility, and ERR signal integration for fault-aware systems.
Technical Context
This SRAM integrates on-die ECC encoding/decoding logic that automatically detects and corrects single-bit errors during read cycles without external circuitry. The ERR pin asserts HIGH only when correction occurs, enabling system-level logging or recovery actions.
It supports both single CE (CE pin only) and dual CE (CE1/CE2) addressing modes, byte-wide writes via BHE/ BLE controls, and full 16-bit parallel I/O. Data retention is guaranteed down to 1.0 V, and all I/Os enter HI-Z state upon deselection or control deassertion.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 4 Mbit (256K words × 16 bits) - provides 512 KB of byte-addressable, non-refreshed volatile storage. |
| Access Time | 45 ns - enables direct interface with 22.22 MHz synchronous bus controllers without wait states. |
| Supply Voltage Range | 2.2 V–3.6 V or 4.5 V–5.5 V - supports dual-rail legacy and modern low-voltage systems without level-shifting. |
| Standby Current | Typical 3.5 µA - allows battery-backed operation for >10 years in industrial data loggers. |
| ECC Function | On-die single-bit error correction with ERR output - eliminates need for external ECC logic or software overhead. |
| Operating Temperature | –40 °C to +85 °C - qualified for industrial-grade embedded applications without derating. |
| Data Retention Voltage | 1.0 V - maintains stored data during brown-out conditions until backup power engages. |
Pinout & Package
Package: 44-pin TSOP II (Type II, 400 mil width), RoHS-compliant, lead-free.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A17 | Address Inputs | 18-bit address bus supporting full 256K-word addressing; A12–A17 used for row/column decoding. |
| I/O0–I/O15 | Bidirectional Data Bus | 16-bit parallel interface; high-impedance when OE, CE, BHE, and BLE are inactive. |
| CE | Chip Enable (Active LOW) | Single-chip-enable mode: device selected only when CE = LOW; all I/Os disabled when HIGH. |
| OE | Output Enable (Active LOW) | Controls read-data output drive; I/Os remain in HI-Z if OE is HIGH during read cycle. |
| WE | Write Enable (Active LOW) | Initiates write operation; data latched on rising edge of WE when CE and OE are asserted. |
| BLE / BHE | Byte Low/High Enable | BLE enables I/O0–I/O7; BHE enables I/O8–I/O15 - supports 8-bit sub-word writes without masking. |
| ERR | Error Indication Output | Open-drain, active-HIGH signal asserted only when single-bit error is detected and corrected. |
| VCC / VSS | Power / Ground | VCC accepts 2.2–3.6 V or 4.5–5.5 V; dual VSS pins reduce ground bounce in high-speed operation. |
Key Features
| Feature | Design Value |
|---|---|
| Embedded ECC engine | Hardware-accelerated single-bit error correction with no CPU intervention or latency penalty. |
| Ultra-low standby power | 3.5 µA typical ISB2 enables multi-year operation in energy-constrained remote sensors. |
| Dual voltage range support | Eliminates need for separate 3.3 V and 5 V memory families - simplifies BOM and layout reuse. |
| ERR output pin | Direct hardware flag for error events - enables deterministic system response without polling or interrupts. |
| 1.0 V data retention | Preserves memory contents during undervoltage lockout (UVLO) or battery switchover transitions. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar ECC SRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ISSI IS62WV25616BLL-45NLI | No integrated ECC; requires external error-handling logic or software correction. | Suitable for cost-sensitive designs where ECC is optional and system-level correction is acceptable. | Select when BOM cost reduction outweighs reliability assurance and board space permits external ECC implementation. |
| Micron MT45W8MW16BGX-45IT:D | 45 ns access, but only supports 3.3 V operation (no 4.5–5.5 V range); includes built-in ECC. | Limited to single-voltage systems; lacks dual-rail flexibility required for mixed-signal legacy interfaces. | Choose for new 3.3 V-only designs prioritizing Micron's long-term supply commitment over voltage versatility. |
Compared with IS62WV25616BLL-45NLI and MT45W8MW16BGX-45IT:D, CY62146GE-45ZSXI uniquely combines dual-voltage support, hardware ECC with dedicated ERR signaling, and industrial temperature rating - making it optimal for field-deployed systems where voltage interoperability and autonomous error reporting are mandatory.

FAQ
Does CY62146GE-45ZSXI support automatic error correction without host intervention?
Yes. The device performs fully autonomous single-bit error detection and correction on every read cycle using on-die ECC logic. No host processor action or firmware routine is required - corrected data appears on I/O lines, and the ERR pin pulses HIGH to signal the event.
What is the function of the ERR pin, and how should it be interfaced?
The ERR pin is an open-drain output that asserts HIGH only when a single-bit error is detected and corrected during a read access. It must be pulled up externally (typically to VCC) and can directly drive an interrupt input or status LED. No debouncing or filtering is required per datasheet timing.
Can CY62146GE-45ZSXI operate reliably at 3.3 V?
Yes. The 2.2 V–3.6 V supply range explicitly includes 3.3 V operation. All AC/DC specifications - including 45 ns access time and 3.5 µA standby current - are guaranteed at VCC = 3.3 V and TA = –40 °C to +85 °C per the Industrial grade specification.
Is the 44-pin TSOP II package of CY62146GE-45ZSXI pin-compatible with earlier CY62146G variants?
Yes, for single-CE configurations. The CY62146GE-45ZSXI uses the same 44-pin TSOP II footprint and signal mapping as CY62146G-45ZSXI, with ERR replacing the NC pin at position 29. No PCB redesign is needed when upgrading to ECC-enabled functionality.
