Product details
Overview
CY62147GE18-55ZSXI from Infineon Technologies (formerly Cypress) is a 4-Mbit MoBL® SRAM with embedded single-bit error-correcting code (ECC), configured as 256K × 16-bit, operating at 55 ns access time across 1.65–2.2 V supply, featuring ERR output pin, ultra-low standby current (3.5 µA typical), and TTL-compatible I/Os - deployed in industrial-grade memory subsystems for medical imaging buffers and avionics data loggers.
For engineers reviewing the CY62147GE18-55ZSXI datasheet, CY62147GE18-55ZSXI pinout, CY62147GE18-55ZSXI application, or CY62147GE18-55ZSXI equivalent, key selection criteria include ECC-enabled reliability, dual-voltage support (1.65–2.2 V), 48-ball VFBGA package compatibility, and ERR signal behavior during single-bit correction events.
Technical Context
This SRAM implements a synchronous, byte-selectable CMOS architecture with independent BHE/ BLE controls for upper/lower 8-bit writes and reads, and integrates dedicated ECC encoder/decoder logic that detects and corrects single-bit errors on every read cycle without requiring external logic. The ERR pin asserts HIGH only when correction occurs - no automatic write-back is performed.
It supports three VCC ranges (1.65–2.2 V, 2.2–3.6 V, 4.5–5.5 V), but CY62147GE18-55ZSXI is specifically rated for 1.65–2.2 V operation at 55 ns. Its Byte Power Down feature enables automatic transition to standby mode when both BHE and BLE are deasserted - independent of CE state - reducing leakage in partial-access memory systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 4 Mbit (256K words × 16-bit) - supports 32 KB of wide-data storage per device, ideal for burst-mode buffering in microcontroller peripherals. |
| Access Time | 55 ns - guarantees deterministic read latency for real-time control loops running at ≤18.18 MHz bus frequency. |
| VCC Range | 1.65 V to 2.2 V - compatible with low-voltage FPGA I/O banks and battery-backed industrial SoCs. |
| Standby Current | 3.5 µA typical / 10 µA max - enables multi-year operation in energy-constrained edge sensor nodes with periodic wake-up. |
| ECC Function | Single-bit error detection and correction per read - reduces uncorrectable error rate to <0.1 FIT/Mb, critical for safety-critical logging. |
| ERR Pin Behavior | Open-drain output asserted HIGH only during correction event - allows direct connection to interrupt controller without level-shifting. |
| Package | 48-ball VFBGA (6 mm × 8 mm, 0.8 mm pitch) - supports high-density PCB layouts with thermal pad for improved power dissipation. |
Pinout & Package
Package: 48-ball Very Thin Fine-Pitch Ball Grid Array (VFBGA), 6 mm × 8 mm body, 0.8 mm ball pitch, RoHS-compliant, moisture sensitivity level 3.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A17 | Address Inputs | 18-bit address bus supporting full 256K-word addressing; A0–A17 directly map to internal row/column decoders. |
| I/O0–I/O15 | Bidirectional Data Bus | 16-bit parallel interface; HI-Z when CE/OE/BLE/BHE inactive - eliminates bus contention in shared-memory systems. |
| CE1, CE2 | Dual Chip Enable Inputs | Active-LOW CE1 and active-HIGH CE2 required simultaneously for access - prevents accidental enable during power sequencing transients. |
| WE | Write Enable | Active-LOW control synchronizing write cycles; combined with BHE/ BLE determines which byte lanes update memory. |
| OE | Output Enable | Active-LOW signal enabling read data onto I/O lines; independent of CE state for flexible timing control. |
| BHE, BLE | Byte Enable Controls | BHE enables I/O8–I/O15 (upper byte); BLE enables I/O0–I/O7 (lower byte); both LOW forces Byte Power Down mode. |
| ERR | Error Indication Output | Open-drain output asserted HIGH only when ECC corrects a single-bit error - requires external pull-up for interrupt signaling. |
| VCC, VSS | Power and Ground | Dual VCC pins (Balls A16, D1) and multiple VSS balls (C1, E1, G1, H2) reduce IR drop and improve noise immunity. |
Key Features
| Feature | Design Value |
|---|---|
| Embedded ECC Engine | Hardware-accelerated single-bit error correction per read cycle - eliminates need for external ECC logic or software overhead. |
| Byte Power Down Mode | Automatic entry into ultra-low-power standby when BHE and BLE are both deasserted - cuts ICC to 3.5 µA regardless of CE status. |
| Voltage Flexibility | Supports 1.65–2.2 V, 2.2–3.6 V, and 4.5–5.5 V rails - allows reuse across legacy 5 V, modern 3.3 V, and ultra-low-power 1.8 V designs. |
| TTL-Compatible I/O | VIH/VIL thresholds meet TTL logic levels at all VCC ranges - ensures interoperability with mixed-voltage microcontrollers and FPGAs. |
| Industrial Temperature Range | Rated for –40 °C to +85 °C ambient - validated for continuous operation in enclosed industrial enclosures without forced cooling. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ECC SRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ISSI IS61WV25616EDBLL-10MLI | No integrated ECC; requires external error-checking logic or software layer; 10 ns faster (10 ns access), but higher standby current (25 µA typical). | Lacks hardware-level error correction - unsuitable for safety-critical or long-term unattended logging where silent data corruption must be prevented. | Select only if speed is primary constraint and system-level ECC can be implemented reliably in firmware or companion logic. |
| Micron MT45W8MW16BGX-55 IT:D | DDR2 SDRAM with optional on-die ECC (not enabled by default); requires clocked interface and refresh management; 55 ns latency includes tRCD + tCL. | Not pin-compatible; demands memory controller with DDR2 timing compliance - increases design complexity versus SRAM's simplicity. | Choose only when bandwidth >200 MB/s is required and system already uses DDR2 infrastructure; avoid for deterministic latency-critical use cases. |
Compared with IS61WV25616EDBLL-10MLI and MT45W8MW16BGX-55 IT:D, CY62147GE18-55ZSXI delivers verified hardware ECC with zero software overhead, guaranteed 55 ns latency, and lowest standby power in its class - making it optimal for resource-constrained, safety-aware embedded memory applications.

FAQ
Does CY62147GE18-55ZSXI support automatic write-back after ECC correction?
No. The device detects and corrects single-bit errors during read operations but does not perform automatic write-back to memory. Corrected data appears on I/O lines, and the ERR pin signals the event, but the original corrupted word remains unchanged in the array unless explicitly rewritten by the host system.
What is the function of the ERR pin during normal (error-free) operation?
During error-free reads, the ERR pin remains in high-impedance (HI-Z) state. It only drives HIGH (open-drain, requires external pull-up) when a single-bit error is detected and corrected. No pull-down is needed, and the pin does not toggle or pulse - it latches HIGH until the next read access.
Can CY62147GE18-55ZSXI operate at 1.5 V?
No. The absolute minimum VCC is 1.65 V per datasheet specifications. Operation below 1.65 V violates maximum ratings and may result in undefined behavior, including ECC failure, data retention loss, or increased soft-error susceptibility - it is not characterized or guaranteed.
Is the 48-ball VFBGA package of CY62147GE18-55ZSXI compatible with standard reflow profiles?
Yes. The package complies with IPC/JEDEC J-STD-020D moisture sensitivity level 3 and is qualified for standard lead-free reflow profiles (peak temperature 260 °C, 60-second duration above 217 °C). Thermal pad (ball E3) must be soldered to PCB ground plane for optimal thermal performance and signal integrity.
