Product details
Overview
CY7S1049GE30-10VXI from Cypress Semiconductor is a 4-Mbit (512K × 8) static RAM with embedded Error Correcting Code (ECC), PowerSnooze™ ultra-low-power Deep-Sleep mode (15 µA), 10 ns access time, and TTL-compatible I/O. It operates across 2.2 V–3.6 V supply range and features an ERR output pin for single-bit error detection/correction-used in industrial control systems requiring high-reliability data storage under thermal stress.
For engineers reviewing the CY7S1049GE30-10VXI datasheet, CY7S1049GE30-10VXI pinout, CY7S1049GE30-10VXI application, or CY7S1049GE30-10VXI equivalent, this device delivers deterministic ECC correction, sub-20 µA retention power, dual-voltage operation, and verified TSOP II package compatibility for legacy SRAM drop-in upgrades in avionics and medical data loggers.
Technical Context
The CY7S1049GE30-10VXI implements on-die ECC encoding/decoding logic that detects and corrects single-bit errors in real time during read operations, with ERR pin assertion confirming correction event. Its PowerSnooze™ architecture enables transition to Deep-Sleep mode via DS pin assertion, reducing current to 15 µA while retaining data at 1.0 V.
It supports three VCC ranges (1.65–2.2 V, 2.2–3.6 V, 4.5–5.5 V); the "30" suffix denotes 2.2–3.6 V operation with 10 ns tAA. The "E" in CY7S1049GE confirms presence of ERR pin; "VXI" indicates Industrial temperature grade (–40°C to +85°C) and 44-pin TSOP II package.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Size | 4 Mbit (512K words × 8 bits): supports byte-wide data bus interface without external multiplexing. |
| Access Time (tAA) | 10 ns at VCC = 2.2–3.6 V: enables direct replacement in 10 ns SRAM-based microcontroller address/data buses. |
| Deep-Sleep Current (IDS) | 15 µA max: allows >1-year battery-backed operation in remote sensor nodes with infrequent wake cycles. |
| ECC Functionality | Single-bit error detection and correction per 8-bit word: eliminates soft-error-induced crashes in radiation-prone environments. |
| ERR Pin Output | Dedicated open-drain output indicating corrected single-bit error: enables firmware logging without polling overhead. |
| Operating Voltage | 2.2 V–3.6 V: compatible with 3.3 V system rails and mixed-voltage FPGA/ASIC interfaces. |
| Data Retention Voltage | 1.0 V min: ensures nonvolatile hold during brown-out events down to critical supply threshold. |
Pinout & Package
Package: 44-pin Thin Small Outline Package Type II (TSOP II), 400-mil width, RoHS-compliant, surface-mount.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| /CE | Chip Enable (active-low) | Primary device selection signal; must be LOW for read/write access; HIGH places outputs in high-impedance state. |
| /OE | Output Enable (active-low) | Controls data bus drivers; LOW enables I/O pins as outputs during read; HIGH disables outputs. |
| /WE | Write Enable (active-low) | Asserted LOW with /CE LOW to initiate write cycle; timing-critical for setup/hold relative to address and data. |
| DS | Deep-Sleep input | LOW activates 15 µA retention mode; HIGH enables normal operation; no internal pull-up/pull-down. |
| ERR | Error indication output | Open-drain output asserted LOW when single-bit error is detected and corrected; requires external pull-up. |
| A0–A18 | Address inputs | 19-bit address bus supporting full 512K-word addressing; A0 least significant bit, A18 most significant. |
| I/O0–I/O7 | Bidirectional data bus | 8-bit TTL-compatible data path; direction controlled by /OE and /WE states; high-impedance when disabled. |
Key Features
| Feature | Design Value |
|---|---|
| Embedded ECC logic | On-die Hamming-code encoder/decoder corrects single-bit errors per 8-bit word without CPU intervention. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ECC-enabled SRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IS61WV5128BLL-10MLI | No embedded ECC; requires external error-handling logic; 10 ns access, 3.3 V only; 48-pin TSOPII. | Lacks hardware error correction; increases firmware complexity and latency for error recovery. | Select only if ECC is implemented externally and board layout accommodates larger 48-pin footprint. |
| AS6C4008-10TIN | 4-Mbit SRAM with no ECC; 10 ns access; 2.7–3.6 V; 32-pin SOJ; no ERR pin or Deep-Sleep mode. | Higher standby current (30 µA vs. 6 mA ISB2, no IDS spec); no error reporting capability. | Use only in cost-sensitive, non-safety-critical applications where ECC is unnecessary and power budget permits. |
Compared with IS61WV5128BLL-10MLI and AS6C4008-10TIN, CY7S1049GE30-10VXI uniquely integrates ECC correction, ERR signaling, and 15 µA Deep-Sleep-enabling safer, lower-power, and more maintainable designs in regulated industrial and transportation systems.

FAQ
Does CY7S1049GE30-10VXI support automatic error correction without CPU intervention?
Yes. The device performs single-bit error detection and correction autonomously during read operations using on-die ECC logic. No firmware action is required-the corrected data appears on I/O pins, and the ERR pin pulses LOW to indicate correction occurred.
What is the minimum VCC required to retain data in Deep-Sleep mode?
Data retention is guaranteed down to 1.0 V in Deep-Sleep mode, as specified in the datasheet. This allows operation with depleted backup batteries or during brown-out conditions where main supply drops below nominal levels.
Can the ERR pin be left unconnected if error logging is not needed?
No. The ERR pin is an open-drain output and requires an external pull-up resistor (typically 4.7 kΩ to VCC) to function correctly. Leaving it floating may cause undefined logic states and interfere with system-level error monitoring.
Is CY7S1049GE30-10VXI pin-compatible with standard 44-pin TSOP II SRAMs like CY62167EV30?
Yes-pinout matches industry-standard 44-pin TSOP II SRAMs for /CE, /OE, /WE, A0–A18, and I/O0–I/O7. However, DS and ERR pins are additional functions not present on non-PowerSnooze™ devices; unused pins must be tied per design guidelines (DS to VCC, ERR to pull-up).
