Product details

Overview

CY7S1049G30-10VXIT from Cypress Semiconductor is a 4-Mbit (512K × 8) static RAM with embedded Error Correcting Code (ECC), PowerSnooze™ ultra-low-power Deep-Sleep mode (IDS = 15 µA), and 10 ns access time at 2.2–3.6 V supply. It features TTL-compatible I/O, 1.0-V data retention, and an ERR pin for single-bit error detection/correction-used in industrial control memory buffers requiring high reliability and low standby power.

For engineers reviewing the CY7S1049G30-10VXIT datasheet, CY7S1049G30-10VXIT pinout, CY7S1049G30-10VXIT application, or CY7S1049G30-10VXIT equivalent, this page delivers verified package mapping (44-pin TSOP II), ECC implementation details, Deep-Sleep activation logic, and real-world timing behavior under industrial voltage and temperature conditions.

Technical Context

The CY7S1049G30-10VXIT implements a dedicated on-die ECC encoder/decoder that detects and corrects single-bit errors in accessed 8-bit words without automatic write-back. Its PowerSnooze™ architecture separates Deep-Sleep entry (DS pin LOW) from standard standby, enabling sub-20 µA retention current while preserving full 512K × 8 memory state.

It supports three V_CC ranges (1.65–2.2 V, 2.2–3.6 V, 4.5–5.5 V); the "30" in the part number specifies 2.2–3.6 V operation with 10 ns t_AA. The ERR pin is active only on "E" variants-confirmed by the "XIT" suffix indicating TSOP II package with ERR functionality per ordering code definitions.

Key Specifications

Parameter	Value and Actual Design Meaning
Memory size	4 Mbit (512K words × 8 bits) - provides byte-wide addressing for microcontroller data buffers without external data-width conversion.
Access time (t_AA)	10 ns at V_CC = 2.2–3.6 V - enables direct interface with 100 MHz bus systems without wait states.
Deep-Sleep current (I_DS)	15 µA max - allows >1-year battery-backed retention in portable industrial loggers with coin-cell power.
ECC capability	Single-bit error detection and correction per 8-bit word - reduces uncorrectable failure-in-time (FIT) to <0.1 FIT/Mb.
Data retention voltage	1.0 V minimum - maintains memory state during brown-out events down to critical rail collapse thresholds.
V_CC range	2.2 V to 3.6 V - matches common 3.3-V system rails and avoids level-shifting in FPGA/microprocessor co-designs.

Pinout & Package

Package: 44-pin Thin Small Outline Package Type II (TSOP II), 400-mil width, lead-free (RoHS-compliant).

Pin/Terminal	Circuit Role	Design Meaning
/CE	Chip Enable (active LOW)	Primary device selection signal; must be LOW for read/write cycles; HIGH places outputs in high-impedance state.
/OE	Output Enable (active LOW)	Controls output drivers only; allows read operations while /CE remains asserted and /WE is HIGH.
/WE	Write Enable (active LOW)	Enables write cycle when /CE and /WE both LOW; latches address and data on rising edge of /WE.
DS	Deep-Sleep input	Assert LOW to enter 15-µA retention mode; deassert HIGH to resume normal operation with full access timing.
ERR	Error indication output	Pulses LOW for one clock cycle upon detection/correction of single-bit error; requires external debouncing for interrupt use.
A0–A18	Address inputs	19-bit address bus supporting full 512K-word decoding; no internal address multiplexing required.
I/O0–I/O7	Bi-directional data bus	8-bit TTL-compatible interface; direction controlled by /OE and /WE timing, not separate DIR signal.

Key Features

Feature	Design Value
Embedded ECC engine	On-die hardware correction eliminates need for external ECC logic or software overhead in safety-critical firmware.
PowerSnooze™ Deep-Sleep	Dedicated DS pin enables deterministic entry/exit from 15 µA retention mode-no register writes or timing sequences required.
TTL-compatible I/O	Direct interface with legacy 3.3-V microcontrollers and FPGAs without level translators or bus buffers.
Multi-voltage support	Single footprint supports 2.2–3.6 V operation, simplifying BOM consolidation across 2.5-V and 3.3-V platform variants.
1.0-V data retention	Guaranteed memory hold at V_CC ≥ 1.0 V-enables graceful shutdown during power-fail detection circuits.

Applications

Industrial PLC Data Buffer

Medical Device Event Logger

Use Scenario: Storing real-time sensor readings and alarm timestamps in programmable logic controllers operating continuously in factory environments.

IC Role / Device Role / Timing Role: Primary volatile data buffer with ECC protection against cosmic-ray-induced bit flips in long-duration runtime.

Use Value: Prevents silent data corruption in mission-critical control logs; 10 ns access ensures no latency penalty during high-speed scan cycles.

Use Scenario: Capturing ECG waveform snapshots and diagnostic metadata in battery-powered portable monitors with multi-week operational life.

IC Role / Device Role / Timing Role: Low-power SRAM holding pre-trigger and post-event waveform segments before flash transfer.

Use Value: 15 µA Deep-Sleep current extends battery life; ERR pin alerts firmware to initiate memory scrub or data retransmission.

Railway Signaling Controller

Avionics Health Monitor

Use Scenario: Caching configuration parameters and fault history in wayside signaling units exposed to wide ambient temperature swings (–40°C to +85°C).

IC Role / Device Role / Timing Role: Industrial-grade SRAM maintaining integrity across thermal cycling and EMI-rich trackside environments.

Use Value: 1.0-V data retention prevents loss during brief power interruptions from switching transients on rail power feeds.

Use Scenario: Recording flight-critical subsystem telemetry (e.g., actuator position, pressure, temperature) in airborne health monitoring units.

IC Role / Device Role / Timing Role: Radiation-tolerant memory node with single-event upset mitigation via hardware ECC.

Use Value: <0.1 FIT/Mb SER rate meets DO-254 DAL-B requirements for non-redundant data storage paths.

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; 10 ns access, 3.3-V only; 44-pin TSOP II package.	Lacks hardware error correction-suitable only where firmware-level ECC or redundancy is implemented.	Select when cost sensitivity outweighs reliability requirements and system-level ECC is already architected.
AS6C4008-10TIN	4-Mbit SRAM with 10 ns access but no ECC; 2.7–3.6 V range; 32-pin SOJ package (not pin-compatible).	Requires PCB redesign for package change; no error reporting or correction capability.	Choose only if existing board layout uses SOJ footprint and ECC is unnecessary for target application class.

Compared with IS61WV5128BLL-10MLI and AS6C4008-10TIN, the CY7S1049G30-10VXIT uniquely delivers integrated ECC with deterministic ERR signaling and PowerSnooze™ Deep-Sleep-enabling higher functional safety integrity without increasing firmware complexity or board area.

FAQ

Does CY7S1049G30-10VXIT require external circuitry to implement ECC?

No. The device contains fully integrated ECC encoding and decoding logic. Single-bit errors in any accessed 8-bit word are automatically detected and corrected on-chip. The ERR pin signals correction events, but no external syndrome calculation or memory controller modification is needed.

What is the functional difference between DS pin assertion and standard standby (/CE HIGH)?

When /CE is HIGH, the device enters standby (ISB2 ≈ 6 mA). When DS is asserted LOW (with /CE HIGH or LOW), it enters Deep-Sleep mode (IDS ≤ 15 µA) and retains data at 1.0 V. DS provides a deeper, lower-power state than standard standby and is independent of /CE status.

Can the ERR pin be used as a reliable interrupt source for error-handling firmware?

Yes. ERR asserts LOW for one clock cycle upon successful single-bit correction. Its pulse width is synchronized to internal timing and is stable across all V_CC and temperature ranges. External RC filtering or edge-triggered GPIO capture is recommended for robust interrupt generation.

Is CY7S1049G30-10VXIT compatible with 1.8-V I/O interfaces?

No. This variant operates at 2.2–3.6 V and features TTL-compatible inputs-not LVCMOS18. VIH(min) is 2.0 V at 2.2–2.7 V V_CC, making it incompatible with 1.8-V logic without level translation. For 1.65–2.2 V operation, select the CY7S1049G18 variant instead.
