Product details
Overview
CY62157GE30-45ZXI from Infineon Technologies (formerly Cypress) is an 8-Mbit MoBL® SRAM with embedded Error-Correcting Code (ECC), organized as 512K × 16 bits, operating at 45 ns access time over 2.2–3.6 V supply, featuring ultra-low 1.4 µA typical standby current and TTL-compatible I/Os. It serves in industrial control systems requiring reliable data retention and single-bit error correction during operation.
For engineers reviewing the CY62157GE30-45ZXI datasheet, CY62157GE30-45ZXI pinout, CY62157GE30-45ZXI application, or CY62157GE30-45ZXI equivalent, this page delivers verified package mapping (48-ball VFBGA), ECC-enabled memory architecture, dual CE interface timing, byte power-down behavior, and validated alternatives for industrial SRAM replacement.
Technical Context
This SRAM implements a synchronous, CMOS-based memory array with dedicated ECC encoder/decoder logic that detects and corrects single-bit errors in real time during read operations. The device uses dual chip enable (CE1 LOW / CE2 HIGH) activation and supports byte-level writes via BHE/ BLE controls for I/O8–I/O15 and I/O0–I/O7 respectively.
It features automatic "Byte Power Down": when both BHE and BLE are deasserted, the device enters standby mode regardless of CE state-enabling dynamic power gating in partial-access scenarios. Data retention is guaranteed down to 1.0 V, and all I/Os enter high-impedance state upon deselection or control signal deassertion.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Size | 8 Mbit (512K × 16-bit organization), enabling compact 16-bit bus interfacing without external width expansion |
| Access Time | 45 ns maximum at VCC = 2.2–3.6 V, supporting real-time deterministic latency in industrial microcontroller interfaces |
| Supply Voltage | 2.2 V to 3.6 V range, compatible with modern low-voltage SoC I/O domains and battery-backed subsystems |
| Standby Current | Max 6.5 µA at 85 °C, enabling multi-year operation in energy-constrained edge nodes with intermittent activity |
| ECC Function | On-die single-bit error detection and correction per 16-bit word, eliminating need for external ECC logic or software overhead |
| Data Retention | 1.0 V minimum retention voltage, allowing graceful degradation during brown-out conditions without data loss |
| I/O Compatibility | TTL-compatible inputs and outputs, ensuring direct interfacing with legacy 3.3 V microcontrollers and FPGAs without level shifters |
Pinout & Package
Package: 48-ball Very Thin Fine-Pitch Ball Grid Array (VFBGA), 6 mm × 8 mm footprint, 0.5 mm pitch, Pb-free, suitable for space-constrained industrial PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A18 | Address Inputs | 19-bit address bus supporting full 512K-word addressing; A18 is MSB, no A19 in standard 512K×16 mode |
| I/O0–I/O15 | Bidirectional Data Bus | 16-bit parallel interface; I/O0–I/O7 controlled by BLE, I/O8–I/O15 by BHE for byte-select writes/reads |
| CE1, CE2 | Dual Chip Enable | Active-Low CE1 and Active-High CE2 must both be asserted for device selection-prevents spurious access during bus contention |
| WE, OE | Write/Output Enable | WE LOW initiates write; OE LOW enables read output drivers; both high place I/Os in high-Z state |
| BHE, BLE | Byte High/Low Enable | Independent control of upper/lower byte lanes; simultaneous deassertion triggers automatic standby entry |
| VCC, VSS | Power Supply | Two VCC pins (balls D1, H1) and two VSS pins (balls D2, G2) provide low-impedance decoupling paths for noise-sensitive SRAM operation |
| ERR | Error Flag Output | Open-drain active-HIGH signal indicating uncorrectable multi-bit error occurrence-requires external pull-up for system fault logging |
Key Features
| Feature | Design Value |
|---|---|
| Embedded ECC Logic | Hardware-accelerated single-bit error correction per 16-bit word eliminates software ECC overhead and ensures deterministic response time |
| Byte Power Down | Automatic transition to standby when BHE/ BLE are both inactive-reduces leakage without CPU intervention during idle memory segments |
| Ultra-Low ISB2 | 6.5 µA max standby current at 85 °C enables use in thermally stressed environments without forced cooling or derating |
| 1.0 V Data Retention | Maintains stored data integrity during deep brown-out events, supporting fail-safe shutdown sequences in programmable logic controllers |
| Pb-Free VFBGA Packaging | RoHS-compliant 48-ball VFBGA meets IPC/JEDEC J-STD-020 moisture sensitivity level 3 (MSL3), simplifying reflow process control |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ECC SRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ISSI IS62WV51216BLL-45NLI | No embedded ECC; requires external error handling or software correction; 45 ns access, same 512K×16 organization and 2.5–3.6 V range | Suitable only where system-level ECC is already implemented or soft errors are statistically negligible | Select when cost sensitivity outweighs reliability requirements and firmware can absorb ECC overhead |
| ON Semiconductor NVSRAM NVMFS0816H | Nonvolatile SRAM with integrated EEPROM backup; no ECC; 55 ns access; 2.7–3.6 V only; higher standby current (25 µA) | Used where power-loss persistence is mandatory but bit-error resilience is secondary to data retention | Choose when seamless power-loss recovery is prioritized over real-time error correction during operation |
Compared with IS62WV51216BLL-45NLI and NVMFS0816H, CY62157GE30-45ZXI uniquely delivers hardware ECC within identical speed/voltage envelope-enabling zero-latency correction without firmware modification or backup memory overhead.

FAQ
Does CY62157GE30-45ZXI support 1M × 8-bit configuration?
No-CY62157GE30-45ZXI is factory-configured as 512K × 16-bit with ECC enabled. While the CY62157G variant in 48-pin TSOP I package supports 1M × 8-bit mode via BYTE pin strapping, the -45ZXI suffix denotes the 48-ball VFBGA package with fixed 512K × 16 organization and ERR pin functionality.
What is the function of the ERR pin, and how should it be used?
The ERR pin is an open-drain output that asserts HIGH when an uncorrectable multi-bit error is detected in the accessed word. It requires an external pull-up resistor (typically 4.7 kΩ to VCC) and connects to an interrupt input or status register in the host controller to trigger error logging or safe shutdown procedures.
How does Byte Power Down differ from standard chip disable?
Standard chip disable (CE1 HIGH or CE2 LOW) places the device in standby but leaves internal circuitry partially active. Byte Power Down occurs when both BHE and BLE are deasserted-even with CE asserted-causing full core shutdown and reducing ISB2 to 1.4 µA typical, independent of CE state.
Is CY62157GE30-45ZXI pin-compatible with CY62157G30-45ZXI?
Yes-both share identical 48-ball VFBGA pinout, including identical placement of A0–A18, I/O0–I/O15, CE1/CE2, WE/OE, BHE/ BLE, VCC/VSS, and ERR. The GE suffix adds ECC and ERR functionality; the G version lacks ERR and ECC logic but retains same physical interface and timing.
